    Description: The human immunodeficiency virus type 1 (HIV-1) envelope (Env) spike, comprising three gp120 and three gp41 subunits, is a conformational machine that facilitates HIV-1 entry by rearranging from a mature unliganded state, through receptor-bound intermediates, to a post-fusion state. As the sole viral antigen on the HIV-1 virion surface, Env is both the target of neutralizing antibodies and a focus of vaccine efforts. Here we report the structure at 3.5 A resolution for an HIV-1 Env trimer captured in a mature closed state by antibodies PGT122 and 35O22. This structure reveals the pre-fusion conformation of gp41, indicates rearrangements needed for fusion activation, and defines parameters of immune evasion and immune recognition. Pre-fusion gp41 encircles amino- and carboxy-terminal strands of gp120 with four helices that form a membrane-proximal collar, fastened by insertion of a fusion peptide-proximal methionine into a gp41-tryptophan clasp. Spike rearrangements required for entry involve opening the clasp and expelling the termini. N-linked glycosylation and sequence-variable regions cover the pre-fusion closed spike; we used chronic cohorts to map the prevalence and location of effective HIV-1-neutralizing responses, which were distinguished by their recognition of N-linked glycan and tolerance for epitope-sequence variation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4348022/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4348022/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pancera, Marie -- Zhou, Tongqing -- Druz, Aliaksandr -- Georgiev, Ivelin S -- Soto, Cinque -- Gorman, Jason -- Huang, Jinghe -- Acharya, Priyamvada -- Chuang, Gwo-Yu -- Ofek, Gilad -- Stewart-Jones, Guillaume B E -- Stuckey, Jonathan -- Bailer, Robert T -- Joyce, M Gordon -- Louder, Mark K -- Tumba, Nancy -- Yang, Yongping -- Zhang, Baoshan -- Cohen, Myron S -- Haynes, Barton F -- Mascola, John R -- Morris, Lynn -- Munro, James B -- Blanchard, Scott C -- Mothes, Walther -- Connors, Mark -- Kwong, Peter D -- AI0678501/AI/NIAID NIH HHS/ -- AI100645/AI/NIAID NIH HHS/ -- P01 GM056550/GM/NIGMS NIH HHS/ -- P01-GM56550/GM/NIGMS NIH HHS/ -- P30 AI050410/AI/NIAID NIH HHS/ -- R01 GM098859/GM/NIGMS NIH HHS/ -- R01-GM098859/GM/NIGMS NIH HHS/ -- R21 AI100696/AI/NIAID NIH HHS/ -- R21-AI100696/AI/NIAID NIH HHS/ -- UL1 TR000142/TR/NCATS NIH HHS/ -- UM1 AI100645/AI/NIAID NIH HHS/ -- ZIA AI005023-13/Intramural NIH HHS/ -- ZIA AI005024-13/Intramural NIH HHS/ -- England -- Nature. 2014 Oct 23;514(7523):455-61. doi: 10.1038/nature13808.

    Description: A defining feature governing head patterning of jawed vertebrates is a highly conserved gene regulatory network that integrates hindbrain segmentation with segmentally restricted domains of Hox gene expression. Although non-vertebrate chordates display nested domains of axial Hox expression, they lack hindbrain segmentation. The sea lamprey, a jawless fish, can provide unique insights into vertebrate origins owing to its phylogenetic position at the base of the vertebrate tree. It has been suggested that lamprey may represent an intermediate state where nested Hox expression has not been coupled to the process of hindbrain segmentation. However, little is known about the regulatory network underlying Hox expression in lamprey or its relationship to hindbrain segmentation. Here, using a novel tool that allows cross-species comparisons of regulatory elements between jawed and jawless vertebrates, we report deep conservation of both upstream regulators and segmental activity of enhancer elements across these distant species. Regulatory regions from diverse gnathostomes drive segmental reporter expression in the lamprey hindbrain and require the same transcriptional inputs (for example, Kreisler (also known as Mafba), Krox20 (also known as Egr2a)) in both lamprey and zebrafish. We find that lamprey hox genes display dynamic segmentally restricted domains of expression; we also isolated a conserved exonic hox2 enhancer from lamprey that drives segmental expression in rhombomeres 2 and 4. Our results show that coupling of Hox gene expression to segmentation of the hindbrain is an ancient trait with origin at the base of vertebrates that probably led to the formation of rhombomeric compartments with an underlying Hox code.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4209185/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4209185/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, Hugo J -- Bronner, Marianne E -- Krumlauf, Robb -- R01 DE017911/DE/NIDCR NIH HHS/ -- R01 NS086907/NS/NINDS NIH HHS/ -- R01DE017911/DE/NIDCR NIH HHS/ -- R01NS086907/NS/NINDS NIH HHS/ -- England -- Nature. 2014 Oct 23;514(7523):490-3. doi: 10.1038/nature13723.

    Description: Emerging evidence suggests that the ribosome has a regulatory function in directing how the genome is translated in time and space. However, how this regulation is encoded in the messenger RNA sequence remains largely unknown. Here we uncover unique RNA regulons embedded in homeobox (Hox) 5' untranslated regions (UTRs) that confer ribosome-mediated control of gene expression. These structured RNA elements, resembling viral internal ribosome entry sites (IRESs), are found in subsets of Hox mRNAs. They facilitate ribosome recruitment and require the ribosomal protein RPL38 for their activity. Despite numerous layers of Hox gene regulation, these IRES elements are essential for converting Hox transcripts into proteins to pattern the mammalian body plan. This specialized mode of IRES-dependent translation is enabled by an additional regulatory element that we term the translation inhibitory element (TIE), which blocks cap-dependent translation of transcripts. Together, these data uncover a new paradigm for ribosome-mediated control of gene expression and organismal development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4353651/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4353651/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Shifeng -- Tian, Siqi -- Fujii, Kotaro -- Kladwang, Wipapat -- Das, Rhiju -- Barna, Maria -- 7DP2OD00850902/OD/NIH HHS/ -- DP2 OD008509/OD/NIH HHS/ -- R01 GM102519/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Jan 1;517(7532):33-8. doi: 10.1038/nature14010.

    Description: The kinetochore is the crucial apparatus regulating chromosome segregation in mitosis and meiosis. Particularly in meiosis I, unlike in mitosis, sister kinetochores are captured by microtubules emanating from the same spindle pole (mono-orientation) and centromeric cohesion mediated by cohesin is protected in the following anaphase. Although meiotic kinetochore factors have been identified only in budding and fission yeasts, these molecules and their functions are thought to have diverged earlier. Therefore, a conserved mechanism for meiotic kinetochore regulation remains elusive. Here we have identified in mouse a meiosis-specific kinetochore factor that we termed MEIKIN, which functions in meiosis I but not in meiosis II or mitosis. MEIKIN plays a crucial role in both mono-orientation and centromeric cohesion protection, partly by stabilizing the localization of the cohesin protector shugoshin. These functions are mediated mainly by the activity of Polo-like kinase PLK1, which is enriched to kinetochores in a MEIKIN-dependent manner. Our integrative analysis indicates that the long-awaited key regulator of meiotic kinetochore function is Meikin, which is conserved from yeasts to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jihye -- Ishiguro, Kei-ichiro -- Nambu, Aya -- Akiyoshi, Bungo -- Yokobayashi, Shihori -- Kagami, Ayano -- Ishiguro, Tadashi -- Pendas, Alberto M -- Takeda, Naoki -- Sakakibara, Yogo -- Kitajima, Tomoya S -- Tanno, Yuji -- Sakuno, Takeshi -- Watanabe, Yoshinori -- England -- Nature. 2015 Jan 22;517(7535):466-71. doi: 10.1038/nature14097.

    Description: The widespread reorganization of cellular architecture in mitosis is achieved through extensive protein phosphorylation, driven by the coordinated activation of a mitotic kinase network and repression of counteracting phosphatases. Phosphatase activity must subsequently be restored to promote mitotic exit. Although Cdc14 phosphatase drives this reversal in budding yeast, protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A) activities have each been independently linked to mitotic exit control in other eukaryotes. Here we describe a mitotic phosphatase relay in which PP1 reactivation is required for the reactivation of both PP2A-B55 and PP2A-B56 to coordinate mitotic progression and exit in fission yeast. The staged recruitment of PP1 (the Dis2 isoform) to the regulatory subunits of the PP2A-B55 and PP2A-B56 (B55 also known as Pab1; B56 also known as Par1) holoenzymes sequentially activates each phosphatase. The pathway is blocked in early mitosis because the Cdk1-cyclin B kinase (Cdk1 also known as Cdc2) inhibits PP1 activity, but declining cyclin B levels later in mitosis permit PP1 to auto-reactivate. PP1 first reactivates PP2A-B55; this enables PP2A-B55 in turn to promote the reactivation of PP2A-B56 by dephosphorylating a PP1-docking site in PP2A-B56, thereby promoting the recruitment of PP1. PP1 recruitment to human, mitotic PP2A-B56 holoenzymes and the sequences of these conserved PP1-docking motifs suggest that PP1 regulates PP2A-B55 and PP2A-B56 activities in a variety of signalling contexts throughout eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4338534/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4338534/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grallert, Agnes -- Boke, Elvan -- Hagting, Anja -- Hodgson, Ben -- Connolly, Yvonne -- Griffiths, John R -- Smith, Duncan L -- Pines, Jonathon -- Hagan, Iain M -- 092096/Wellcome Trust/United Kingdom -- A13678/Cancer Research UK/United Kingdom -- A16406/Cancer Research UK/United Kingdom -- C147/A16406/Cancer Research UK/United Kingdom -- C29/A13678/Cancer Research UK/United Kingdom -- England -- Nature. 2015 Jan 1;517(7532):94-8. doi: 10.1038/nature14019.

    Description: A fundamental feature of immune systems is the ability to distinguish pathogenic from self and commensal elements, and to attack the former but tolerate the latter. Prokaryotic CRISPR-Cas immune systems defend against phage infection by using Cas nucleases and small RNA guides that specify one or more target sites for cleavage of the viral genome. Temperate phages include viruses that can integrate into the bacterial chromosome, and they can carry genes that provide a fitness advantage to the lysogenic host. However, CRISPR-Cas targeting that relies strictly on DNA sequence recognition provides indiscriminate immunity both to lytic and lysogenic infection by temperate phages-compromising the genetic stability of these potentially beneficial elements altogether. Here we show that the Staphylococcus epidermidis CRISPR-Cas system can prevent lytic infection but tolerate lysogenization by temperate phages. Conditional tolerance is achieved through transcription-dependent DNA targeting, and ensures that targeting is resumed upon induction of the prophage lytic cycle. Our results provide evidence for the functional divergence of CRISPR-Cas systems and highlight the importance of targeting mechanism diversity. In addition, they extend the concept of 'tolerance to non-self' to the prokaryotic branch of adaptive immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214910/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214910/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldberg, Gregory W -- Jiang, Wenyan -- Bikard, David -- Marraffini, Luciano A -- 1DP2AI104556-01/AI/NIAID NIH HHS/ -- DP2 AI104556/AI/NIAID NIH HHS/ -- T32 AI070084/AI/NIAID NIH HHS/ -- England -- Nature. 2014 Oct 30;514(7524):633-7. doi: 10.1038/nature13637.

    Description: Originally conceived to conserve iconic landscapes and wildlife, protected areas are now expected to achieve an increasingly diverse set of conservation, social and economic objectives. The amount of land and sea designated as formally protected has markedly increased over the past century, but there is still a major shortfall in political commitments to enhance the coverage and effectiveness of protected areas. Financial support for protected areas is dwarfed by the benefits that they provide, but these returns depend on effective management. A step change involving increased recognition, funding, planning and enforcement is urgently needed if protected areas are going to fulfil their potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, James E M -- Dudley, Nigel -- Segan, Daniel B -- Hockings, Marc -- England -- Nature. 2014 Nov 6;515(7525):67-73. doi: 10.1038/nature13947.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] School of Geography, Planning and Environmental Management, University of Queensland, St Lucia, Queensland 4072, Australia.

    Description: The reorganization of patterns of species diversity driven by anthropogenic climate change, and the consequences for humans, are not yet fully understood or appreciated. Nevertheless, changes in climate conditions are useful for predicting shifts in species distributions at global and local scales. Here we use the velocity of climate change to derive spatial trajectories for climatic niches from 1960 to 2009 (ref. 7) and from 2006 to 2100, and use the properties of these trajectories to infer changes in species distributions. Coastlines act as barriers and locally cooler areas act as attractors for trajectories, creating source and sink areas for local climatic conditions. Climate source areas indicate where locally novel conditions are not connected to areas where similar climates previously occurred, and are thereby inaccessible to climate migrants tracking isotherms: 16% of global surface area for 1960 to 2009, and 34% of ocean for the 'business as usual' climate scenario (representative concentration pathway (RCP) 8.5) representing continued use of fossil fuels without mitigation. Climate sink areas are where climate conditions locally disappear, potentially blocking the movement of climate migrants. Sink areas comprise 1.0% of ocean area and 3.6% of land and are prevalent on coasts and high ground. Using this approach to infer shifts in species distributions gives global and regional maps of the expected direction and rate of shifts of climate migrants, and suggests areas of potential loss of species richness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burrows, Michael T -- Schoeman, David S -- Richardson, Anthony J -- Molinos, Jorge Garcia -- Hoffmann, Ary -- Buckley, Lauren B -- Moore, Pippa J -- Brown, Christopher J -- Bruno, John F -- Duarte, Carlos M -- Halpern, Benjamin S -- Hoegh-Guldberg, Ove -- Kappel, Carrie V -- Kiessling, Wolfgang -- O'Connor, Mary I -- Pandolfi, John M -- Parmesan, Camille -- Sydeman, William J -- Ferrier, Simon -- Williams, Kristen J -- Poloczanska, Elvira S -- England -- Nature. 2014 Mar 27;507(7493):492-5. doi: 10.1038/nature12976.

    Description: Intestinal microbial communities have profound effects on host physiology. Whereas the symbiotic contribution of commensal bacteria is well established, the role of eukaryotic viruses that are present in the gastrointestinal tract under homeostatic conditions is undefined. Here we demonstrate that a common enteric RNA virus can replace the beneficial function of commensal bacteria in the intestine. Murine norovirus (MNV) infection of germ-free or antibiotic-treated mice restored intestinal morphology and lymphocyte function without inducing overt inflammation and disease. The presence of MNV also suppressed an expansion of group 2 innate lymphoid cells observed in the absence of bacteria, and induced transcriptional changes in the intestine associated with immune development and type I interferon (IFN) signalling. Consistent with this observation, the IFN-alpha receptor was essential for the ability of MNV to compensate for bacterial depletion. Importantly, MNV infection offset the deleterious effect of treatment with antibiotics in models of intestinal injury and pathogenic bacterial infection. These data indicate that eukaryotic viruses have the capacity to support intestinal homeostasis and shape mucosal immunity, similarly to commensal bacteria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4257755/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4257755/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kernbauer, Elisabeth -- Ding, Yi -- Cadwell, Ken -- J 3435/Austrian Science Fund FWF/Austria -- P30CA016087/CA/NCI NIH HHS/ -- R01 DK093668/DK/NIDDK NIH HHS/ -- England -- Nature. 2014 Dec 4;516(7529):94-8. doi: 10.1038/nature13960.

    Description: Antibodies capable of neutralizing HIV-1 often target variable regions 1 and 2 (V1V2) of the HIV-1 envelope, but the mechanism of their elicitation has been unclear. Here we define the developmental pathway by which such antibodies are generated and acquire the requisite molecular characteristics for neutralization. Twelve somatically related neutralizing antibodies (CAP256-VRC26.01-12) were isolated from donor CAP256 (from the Centre for the AIDS Programme of Research in South Africa (CAPRISA)); each antibody contained the protruding tyrosine-sulphated, anionic antigen-binding loop (complementarity-determining region (CDR) H3) characteristic of this category of antibodies. Their unmutated ancestor emerged between weeks 30-38 post-infection with a 35-residue CDR H3, and neutralized the virus that superinfected this individual 15 weeks after initial infection. Improved neutralization breadth and potency occurred by week 59 with modest affinity maturation, and was preceded by extensive diversification of the virus population. HIV-1 V1V2-directed neutralizing antibodies can thus develop relatively rapidly through initial selection of B cells with a long CDR H3, and limited subsequent somatic hypermutation. These data provide important insights relevant to HIV-1 vaccine development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4395007/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4395007/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doria-Rose, Nicole A -- Schramm, Chaim A -- Gorman, Jason -- Moore, Penny L -- Bhiman, Jinal N -- DeKosky, Brandon J -- Ernandes, Michael J -- Georgiev, Ivelin S -- Kim, Helen J -- Pancera, Marie -- Staupe, Ryan P -- Altae-Tran, Han R -- Bailer, Robert T -- Crooks, Ema T -- Cupo, Albert -- Druz, Aliaksandr -- Garrett, Nigel J -- Hoi, Kam H -- Kong, Rui -- Louder, Mark K -- Longo, Nancy S -- McKee, Krisha -- Nonyane, Molati -- O'Dell, Sijy -- Roark, Ryan S -- Rudicell, Rebecca S -- Schmidt, Stephen D -- Sheward, Daniel J -- Soto, Cinque -- Wibmer, Constantinos Kurt -- Yang, Yongping -- Zhang, Zhenhai -- NISC Comparative Sequencing Program -- Mullikin, James C -- Binley, James M -- Sanders, Rogier W -- Wilson, Ian A -- Moore, John P -- Ward, Andrew B -- Georgiou, George -- Williamson, Carolyn -- Abdool Karim, Salim S -- Morris, Lynn -- Kwong, Peter D -- Shapiro, Lawrence -- Mascola, John R -- P01 AI082362/AI/NIAID NIH HHS/ -- R01 AI100790/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2014 May 1;509(7498):55-62. doi: 10.1038/nature13036.

    Description: Corneal epithelial homeostasis and regeneration are sustained by limbal stem cells (LSCs), and LSC deficiency is a major cause of blindness worldwide. Transplantation is often the only therapeutic option available to patients with LSC deficiency. However, while transplant success depends foremost on LSC frequency within grafts, a gene allowing for prospective LSC enrichment has not been identified so far. Here we show that ATP-binding cassette, sub-family B, member 5 (ABCB5) marks LSCs and is required for LSC maintenance, corneal development and repair. Furthermore, we demonstrate that prospectively isolated human or murine ABCB5-positive LSCs possess the exclusive capacity to fully restore the cornea upon grafting to LSC-deficient mice in xenogeneic or syngeneic transplantation models. ABCB5 is preferentially expressed on label-retaining LSCs in mice and p63alpha-positive LSCs in humans. Consistent with these findings, ABCB5-positive LSC frequency is reduced in LSC-deficient patients. Abcb5 loss of function in Abcb5 knockout mice causes depletion of quiescent LSCs due to enhanced proliferation and apoptosis, and results in defective corneal differentiation and wound healing. Our results from gene knockout studies, LSC tracing and transplantation models, as well as phenotypic and functional analyses of human biopsy specimens, provide converging lines of evidence that ABCB5 identifies mammalian LSCs. Identification and prospective isolation of molecularly defined LSCs with essential functions in corneal development and repair has important implications for the treatment of corneal disease, particularly corneal blindness due to LSC deficiency.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4246512/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4246512/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ksander, Bruce R -- Kolovou, Paraskevi E -- Wilson, Brian J -- Saab, Karim R -- Guo, Qin -- Ma, Jie -- McGuire, Sean P -- Gregory, Meredith S -- Vincent, William J B -- Perez, Victor L -- Cruz-Guilloty, Fernando -- Kao, Winston W Y -- Call, Mindy K -- Tucker, Budd A -- Zhan, Qian -- Murphy, George F -- Lathrop, Kira L -- Alt, Clemens -- Mortensen, Luke J -- Lin, Charles P -- Zieske, James D -- Frank, Markus H -- Frank, Natasha Y -- DP2 OD007483/OD/NIH HHS/ -- DP2OD007483/OD/NIH HHS/ -- EY08098/EY/NEI NIH HHS/ -- I01 BX000516/BX/BLRD VA/ -- I01 RX000989/RX/RRD VA/ -- K08 NS051349/NS/NINDS NIH HHS/ -- K08NS051349/NS/NINDS NIH HHS/ -- P30 EY014801/EY/NEI NIH HHS/ -- P30EY014801/EY/NEI NIH HHS/ -- P41EB015903/EB/NIBIB NIH HHS/ -- R01 CA113796/CA/NCI NIH HHS/ -- R01 CA138231/CA/NCI NIH HHS/ -- R01 CA158467/CA/NCI NIH HHS/ -- R01 EB017274/EB/NIBIB NIH HHS/ -- R01CA113796/CA/NCI NIH HHS/ -- R01CA138231/CA/NCI NIH HHS/ -- R01CA158467/CA/NCI NIH HHS/ -- R01EY018624/EY/NEI NIH HHS/ -- R01EY021768/EY/NEI NIH HHS/ -- U01HL100402/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Jul 17;511(7509):353-7. doi: 10.1038/nature13426.

    Description: Nitrate is a primary nutrient for plant growth, but its levels in soil can fluctuate by several orders of magnitude. Previous studies have identified Arabidopsis NRT1.1 as a dual-affinity nitrate transporter that can take up nitrate over a wide range of concentrations. The mode of action of NRT1.1 is controlled by phosphorylation of a key residue, Thr 101; however, how this post-translational modification switches the transporter between two affinity states remains unclear. Here we report the crystal structure of unphosphorylated NRT1.1, which reveals an unexpected homodimer in the inward-facing conformation. In this low-affinity state, the Thr 101 phosphorylation site is embedded in a pocket immediately adjacent to the dimer interface, linking the phosphorylation status of the transporter to its oligomeric state. Using a cell-based fluorescence resonance energy transfer assay, we show that functional NRT1.1 dimerizes in the cell membrane and that the phosphomimetic mutation of Thr 101 converts the protein into a monophasic high-affinity transporter by structurally decoupling the dimer. Together with analyses of the substrate transport tunnel, our results establish a phosphorylation-controlled dimerization switch that allows NRT1.1 to uptake nitrate with two distinct affinity modes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3968801/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3968801/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sun, Ji -- Bankston, John R -- Payandeh, Jian -- Hinds, Thomas R -- Zagotta, William N -- Zheng, Ning -- NS074545/NS/NINDS NIH HHS/ -- R01EY10329/EY/NEI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Mar 6;507(7490):73-7. doi: 10.1038/nature13074.

    Description: Microbes and their viruses drive myriad processes across ecosystems ranging from oceans and soils to bioreactors and humans. Despite this importance, microbial diversity is only now being mapped at scales relevant to nature, while the viral diversity associated with any particular host remains little researched. Here we quantify host-associated viral diversity using viral-tagged metagenomics, which links viruses to specific host cells for high-throughput screening and sequencing. In a single experiment, we screened 10(7) Pacific Ocean viruses against a single strain of Synechococcus and found that naturally occurring cyanophage genome sequence space is statistically clustered into discrete populations. These population-based, host-linked viral ecological data suggest that, for this single host and seawater sample alone, there are at least 26 double-stranded DNA viral populations with estimated relative abundances ranging from 0.06 to 18.2%. These populations include previously cultivated cyanophage and new viral types missed by decades of isolate-based studies. Nucleotide identities of homologous genes mostly varied by less than 1% within populations, even in hypervariable genome regions, and by 42-71% between populations, which provides benchmarks for viral metagenomics and genome-based viral species definitions. Together these findings showcase a new approach to viral ecology that quantitatively links objectively defined environmental viral populations, and their genomes, to their hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deng, Li -- Ignacio-Espinoza, J Cesar -- Gregory, Ann C -- Poulos, Bonnie T -- Weitz, Joshua S -- Hugenholtz, Philip -- Sullivan, Matthew B -- England -- Nature. 2014 Sep 11;513(7517):242-5. doi: 10.1038/nature13459.

    Description: Cultivated bacteria such as actinomycetes are a highly useful source of biomedically important natural products. However, such 'talented' producers represent only a minute fraction of the entire, mostly uncultivated, prokaryotic diversity. The uncultured majority is generally perceived as a large, untapped resource of new drug candidates, but so far it is unknown whether taxa containing talented bacteria indeed exist. Here we report the single-cell- and metagenomics-based discovery of such producers. Two phylotypes of the candidate genus 'Entotheonella' with genomes of greater than 9 megabases and multiple, distinct biosynthetic gene clusters co-inhabit the chemically and microbially rich marine sponge Theonella swinhoei. Almost all bioactive polyketides and peptides known from this animal were attributed to a single phylotype. 'Entotheonella' spp. are widely distributed in sponges and belong to an environmental taxon proposed here as candidate phylum 'Tectomicrobia'. The pronounced bioactivities and chemical uniqueness of 'Entotheonella' compounds provide significant opportunities for ecological studies and drug discovery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Micheal C -- Mori, Tetsushi -- Ruckert, Christian -- Uria, Agustinus R -- Helf, Maximilian J -- Takada, Kentaro -- Gernert, Christine -- Steffens, Ursula A E -- Heycke, Nina -- Schmitt, Susanne -- Rinke, Christian -- Helfrich, Eric J N -- Brachmann, Alexander O -- Gurgui, Cristian -- Wakimoto, Toshiyuki -- Kracht, Matthias -- Crusemann, Max -- Hentschel, Ute -- Abe, Ikuro -- Matsunaga, Shigeki -- Kalinowski, Jorn -- Takeyama, Haruko -- Piel, Jorn -- England -- Nature. 2014 Feb 6;506(7486):58-62. doi: 10.1038/nature12959.

    Description: In photosynthetic organisms, D-ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the major enzyme assimilating atmospheric CO2 into the biosphere. Owing to the wasteful oxygenase activity and slow turnover of Rubisco, the enzyme is among the most important targets for improving the photosynthetic efficiency of vascular plants. It has been anticipated that introducing the CO2-concentrating mechanism (CCM) from cyanobacteria into plants could enhance crop yield. However, the complex nature of Rubisco's assembly has made manipulation of the enzyme extremely challenging, and attempts to replace it in plants with the enzymes from cyanobacteria and red algae have not been successful. Here we report two transplastomic tobacco lines with functional Rubisco from the cyanobacterium Synechococcus elongatus PCC7942 (Se7942). We knocked out the native tobacco gene encoding the large subunit of Rubisco by inserting the large and small subunit genes of the Se7942 enzyme, in combination with either the corresponding Se7942 assembly chaperone, RbcX, or an internal carboxysomal protein, CcmM35, which incorporates three small subunit-like domains. Se7942 Rubisco and CcmM35 formed macromolecular complexes within the chloroplast stroma, mirroring an early step in the biogenesis of cyanobacterial beta-carboxysomes. Both transformed lines were photosynthetically competent, supporting autotrophic growth, and their respective forms of Rubisco had higher rates of CO2 fixation per unit of enzyme than the tobacco control. These transplastomic tobacco lines represent an important step towards improved photosynthesis in plants and will be valuable hosts for future addition of the remaining components of the cyanobacterial CCM, such as inorganic carbon transporters and the beta-carboxysome shell proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4176977/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4176977/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Myat T -- Occhialini, Alessandro -- Andralojc, P John -- Parry, Martin A J -- Hanson, Maureen R -- BB/I024488/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/J/00426X/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- F32 GM103019/GM/NIGMS NIH HHS/ -- F32GM103019/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Sep 25;513(7519):547-50. doi: 10.1038/nature13776.

    Description: Microorganisms evolve via a range of mechanisms that may include or involve sexual/parasexual reproduction, mutators, aneuploidy, Hsp90 and even prions. Mechanisms that may seem detrimental can be repurposed to generate diversity. Here we show that the human fungal pathogen Mucor circinelloides develops spontaneous resistance to the antifungal drug FK506 (tacrolimus) via two distinct mechanisms. One involves Mendelian mutations that confer stable drug resistance; the other occurs via an epigenetic RNA interference (RNAi)-mediated pathway resulting in unstable drug resistance. The peptidylprolyl isomerase FKBP12 interacts with FK506 forming a complex that inhibits the protein phosphatase calcineurin. Calcineurin inhibition by FK506 blocks M. circinelloides transition to hyphae and enforces yeast growth. Mutations in the fkbA gene encoding FKBP12 or the calcineurin cnbR or cnaA genes confer FK506 resistance and restore hyphal growth. In parallel, RNAi is spontaneously triggered to silence the fkbA gene, giving rise to drug-resistant epimutants. FK506-resistant epimutants readily reverted to the drug-sensitive wild-type phenotype when grown without exposure to the drug. The establishment of these epimutants is accompanied by generation of abundant fkbA small RNAs and requires the RNAi pathway as well as other factors that constrain or reverse the epimutant state. Silencing involves the generation of a double-stranded RNA trigger intermediate using the fkbA mature mRNA as a template to produce antisense fkbA RNA. This study uncovers a novel epigenetic RNAi-based epimutation mechanism controlling phenotypic plasticity, with possible implications for antimicrobial drug resistance and RNAi-regulatory mechanisms in fungi and other eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4177005/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4177005/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calo, Silvia -- Shertz-Wall, Cecelia -- Lee, Soo Chan -- Bastidas, Robert J -- Nicolas, Francisco E -- Granek, Joshua A -- Mieczkowski, Piotr -- Torres-Martinez, Santiago -- Ruiz-Vazquez, Rosa M -- Cardenas, Maria E -- Heitman, Joseph -- R01 AI039115/AI/NIAID NIH HHS/ -- R01 AI50438-10/AI/NIAID NIH HHS/ -- R01 CA154499/CA/NCI NIH HHS/ -- R01 CA154499-04/CA/NCI NIH HHS/ -- R37 AI039115/AI/NIAID NIH HHS/ -- R37 AI39115-17/AI/NIAID NIH HHS/ -- England -- Nature. 2014 Sep 25;513(7519):555-8. doi: 10.1038/nature13575.

    Description: The decomposition of dead organic matter is a major determinant of carbon and nutrient cycling in ecosystems, and of carbon fluxes between the biosphere and the atmosphere. Decomposition is driven by a vast diversity of organisms that are structured in complex food webs. Identifying the mechanisms underlying the effects of biodiversity on decomposition is critical given the rapid loss of species worldwide and the effects of this loss on human well-being. Yet despite comprehensive syntheses of studies on how biodiversity affects litter decomposition, key questions remain, including when, where and how biodiversity has a role and whether general patterns and mechanisms occur across ecosystems and different functional types of organism. Here, in field experiments across five terrestrial and aquatic locations, ranging from the subarctic to the tropics, we show that reducing the functional diversity of decomposer organisms and plant litter types slowed the cycling of litter carbon and nitrogen. Moreover, we found evidence of nitrogen transfer from the litter of nitrogen-fixing plants to that of rapidly decomposing plants, but not between other plant functional types, highlighting that specific interactions in litter mixtures control carbon and nitrogen cycling during decomposition. The emergence of this general mechanism and the coherence of patterns across contrasting terrestrial and aquatic ecosystems suggest that biodiversity loss has consistent consequences for litter decomposition and the cycling of major elements on broad spatial scales.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Handa, I Tanya -- Aerts, Rien -- Berendse, Frank -- Berg, Matty P -- Bruder, Andreas -- Butenschoen, Olaf -- Chauvet, Eric -- Gessner, Mark O -- Jabiol, Jeremy -- Makkonen, Marika -- McKie, Brendan G -- Malmqvist, Bjorn -- Peeters, Edwin T H M -- Scheu, Stefan -- Schmid, Bernhard -- van Ruijven, Jasper -- Vos, Veronique C A -- Hattenschwiler, Stephan -- England -- Nature. 2014 May 8;509(7499):218-21. doi: 10.1038/nature13247.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Centre d'Ecologie Fonctionnelle et Evolutive (CEFE), CNRS, 1919 Route de Mende, 34293 Montpellier, France [2] Departement des Sciences Biologiques, Universite du Quebec a Montreal, C.P. 8888, succursale Centre-ville, Montreal, Quebec H3C 3P8, Canada. ; Department of Ecological Science, VU University Amsterdam, De Boelelaan 1085, 1081 HV Amsterdam, The Netherlands. ; Nature Conservation and Plant Ecology Group, Wageningen University, Droevendaalsesteeg 3a, 6708 PB Wageningen, The Netherlands. ; 1] Department of Aquatic Ecology, Eawag: Swiss Federal Institute of Aquatic Science and Technology, Uberlandstrasse 133, 8600 Dubendorf, Switzerland [2] Institute of Integrative Biology (IBZ), ETH Zurich, 8092 Zurich, Switzerland. ; Georg August University Gottingen, J.F.

    Description: Ancient and diverse antibiotic resistance genes (ARGs) have previously been identified from soil, including genes identical to those in human pathogens. Despite the apparent overlap between soil and clinical resistomes, factors influencing ARG composition in soil and their movement between genomes and habitats remain largely unknown. General metagenome functions often correlate with the underlying structure of bacterial communities. However, ARGs are proposed to be highly mobile, prompting speculation that resistomes may not correlate with phylogenetic signatures or ecological divisions. To investigate these relationships, we performed functional metagenomic selections for resistance to 18 antibiotics from 18 agricultural and grassland soils. The 2,895 ARGs we discovered were mostly new, and represent all major resistance mechanisms. We demonstrate that distinct soil types harbour distinct resistomes, and that the addition of nitrogen fertilizer strongly influenced soil ARG content. Resistome composition also correlated with microbial phylogenetic and taxonomic structure, both across and within soil types. Consistent with this strong correlation, mobility elements (genes responsible for horizontal gene transfer between bacteria such as transposases and integrases) syntenic with ARGs were rare in soil by comparison with sequenced pathogens, suggesting that ARGs may not transfer between soil bacteria as readily as is observed between human pathogens. Together, our results indicate that bacterial community composition is the primary determinant of soil ARG content, challenging previous hypotheses that horizontal gene transfer effectively decouples resistomes from phylogeny.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4079543/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4079543/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Forsberg, Kevin J -- Patel, Sanket -- Gibson, Molly K -- Lauber, Christian L -- Knight, Rob -- Fierer, Noah -- Dantas, Gautam -- DP2 DK098089/DK/NIDDK NIH HHS/ -- DP2-DK-098089/DK/NIDDK NIH HHS/ -- GM 007067/GM/NIGMS NIH HHS/ -- T32 GM007067/GM/NIGMS NIH HHS/ -- T32 HG000045/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 May 29;509(7502):612-6. doi: 10.1038/nature13377.

    Description: Liquid water has been known to occur beneath the Antarctic ice sheet for more than 40 years, but only recently have these subglacial aqueous environments been recognized as microbial ecosystems that may influence biogeochemical transformations on a global scale. Here we present the first geomicrobiological description of water and surficial sediments obtained from direct sampling of a subglacial Antarctic lake. Subglacial Lake Whillans (SLW) lies beneath approximately 800 m of ice on the lower portion of the Whillans Ice Stream (WIS) in West Antarctica and is part of an extensive and evolving subglacial drainage network. The water column of SLW contained metabolically active microorganisms and was derived primarily from glacial ice melt with solute sources from lithogenic weathering and a minor seawater component. Heterotrophic and autotrophic production data together with small subunit ribosomal RNA gene sequencing and biogeochemical data indicate that SLW is a chemosynthetically driven ecosystem inhabited by a diverse assemblage of bacteria and archaea. Our results confirm that aquatic environments beneath the Antarctic ice sheet support viable microbial ecosystems, corroborating previous reports suggesting that they contain globally relevant pools of carbon and microbes that can mobilize elements from the lithosphere and influence Southern Ocean geochemical and biological systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Christner, Brent C -- Priscu, John C -- Achberger, Amanda M -- Barbante, Carlo -- Carter, Sasha P -- Christianson, Knut -- Michaud, Alexander B -- Mikucki, Jill A -- Mitchell, Andrew C -- Skidmore, Mark L -- Vick-Majors, Trista J -- WISSARD Science Team -- England -- Nature. 2014 Aug 21;512(7514):310-3. doi: 10.1038/nature13667.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana 70803, USA. ; Department of Land Resources and Environmental Science, Montana State University, Bozeman, Montana 59717, USA. ; Institute for the Dynamics of Environmental Processes - CNR, Venice, and Department of Environmental Sciences, Informatics and Statistics, Ca'Foscari University of Venice, Venice 30123, Italy. ; Institute of Geophysics and Planetary Physics, Scripps Institution of Oceanography, University of California San Diego, La Jolla, California 92093, USA. ; 1] Physics Department, St Olaf College, Northfield, Minnesota 55057, USA [2] Courant Institute of Mathematical Sciences, New York University, New York, New York 10012, USA (K.C.). ; Department of Microbiology, University of Tennessee, Knoxville, Tennessee 37996, USA. ; Department of Geography and Earth Sciences, Aberystwyth University, Aberystwyth SY23 3DB, UK. ; Department of Earth Science, Montana State University, Bozeman, Montana 59717, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25143114" target="_blank"〉PubMed〈/a〉

    Description: Neurotransmitter-gated ion channels of the Cys-loop receptor family mediate fast neurotransmission throughout the nervous system. The molecular processes of neurotransmitter binding, subsequent opening of the ion channel and ion permeation remain poorly understood. Here we present the X-ray structure of a mammalian Cys-loop receptor, the mouse serotonin 5-HT3 receptor, at 3.5 A resolution. The structure of the proteolysed receptor, made up of two fragments and comprising part of the intracellular domain, was determined in complex with stabilizing nanobodies. The extracellular domain reveals the detailed anatomy of the neurotransmitter binding site capped by a nanobody. The membrane domain delimits an aqueous pore with a 4.6 A constriction. In the intracellular domain, a bundle of five intracellular helices creates a closed vestibule where lateral portals are obstructed by loops. This 5-HT3 receptor structure, revealing part of the intracellular domain, expands the structural basis for understanding the operating mechanism of mammalian Cys-loop receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hassaine, Gherici -- Deluz, Cedric -- Grasso, Luigino -- Wyss, Romain -- Tol, Menno B -- Hovius, Ruud -- Graff, Alexandra -- Stahlberg, Henning -- Tomizaki, Takashi -- Desmyter, Aline -- Moreau, Christophe -- Li, Xiao-Dan -- Poitevin, Frederic -- Vogel, Horst -- Nury, Hugues -- England -- Nature. 2014 Aug 21;512(7514):276-81. doi: 10.1038/nature13552.

    Description: Historically, farmers and hunter-gatherers relied directly on ecosystem services, which they both exploited and enjoyed. Urban populations still rely on ecosystems, but prioritize non-ecosystem services (socioeconomic). Population growth and densification increase the scale and change the nature of both ecosystem- and non-ecosystem-service supply and demand, weakening direct feedbacks between ecosystems and societies and potentially pushing social-ecological systems into traps that can lead to collapse. The interacting and mutually reinforcing processes of technological change, population growth and urbanization contribute to over-exploitation of ecosystems through complex feedbacks that have important implications for sustainable resource use.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cumming, Graeme S -- Buerkert, Andreas -- Hoffmann, Ellen M -- Schlecht, Eva -- von Cramon-Taubadel, Stephan -- Tscharntke, Teja -- England -- Nature. 2014 Nov 6;515(7525):50-7. doi: 10.1038/nature13945.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Percy FitzPatrick Institute, DST/NRF Centre of Excellence, University of Cape Town, Rondebosch, Cape Town 7701, South Africa. ; Organic Plant Production and Agroecosystems Research in the Tropics and Subtropics, Universitat Kassel, Steinstr. 19, D-37213 Witzenhausen, Germany. ; Animal Husbandry in the Tropics and Subtropics, Universitat Kassel and Georg-August-Universitat Gottingen, Steinstr. 19, D-37213 Witzenhausen, Germany. ; Department of Agricultural Economics and Rural Development, Georg-August-Universitat, Platz der Gottinger Sieben 5, D-37073 Germany. ; Agroecology, Georg-August-Universitat Gottingen, Grisebachstr. 6, D-37077 Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25373674" target="_blank"〉PubMed〈/a〉

    Description: H2A.Z is an essential histone variant implicated in the regulation of key nuclear events. However, the metazoan chaperones responsible for H2A.Z deposition and its removal from chromatin remain unknown. Here we report the identification and characterization of the human protein ANP32E as a specific H2A.Z chaperone. We show that ANP32E is a member of the presumed H2A.Z histone-exchange complex p400/TIP60. ANP32E interacts with a short region of the docking domain of H2A.Z through a new motif termed H2A.Z interacting domain (ZID). The 1.48 A resolution crystal structure of the complex formed between the ANP32E-ZID and the H2A.Z/H2B dimer and biochemical data support an underlying molecular mechanism for H2A.Z/H2B eviction from the nucleosome and its stabilization by ANP32E through a specific extension of the H2A.Z carboxy-terminal alpha-helix. Finally, analysis of H2A.Z localization in ANP32E(-/-) cells by chromatin immunoprecipitation followed by sequencing shows genome-wide enrichment, redistribution and accumulation of H2A.Z at specific chromatin control regions, in particular at enhancers and insulators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Obri, Arnaud -- Ouararhni, Khalid -- Papin, Christophe -- Diebold, Marie-Laure -- Padmanabhan, Kiran -- Marek, Martin -- Stoll, Isabelle -- Roy, Ludovic -- Reilly, Patrick T -- Mak, Tak W -- Dimitrov, Stefan -- Romier, Christophe -- Hamiche, Ali -- England -- Nature. 2014 Jan 30;505(7485):648-53. doi: 10.1038/nature12922.

    Description: RNA is arguably the most functionally diverse biological macromolecule. In some cases a single discrete RNA sequence performs multiple roles, and this can be conferred by a complex three-dimensional structure. Such multifunctionality can also be driven or enhanced by the ability of a given RNA to assume different conformational (and therefore functional) states. Despite its biological importance, a detailed structural understanding of the paradigm of RNA structure-driven multifunctionality is lacking. To address this gap it is useful to study examples from single-stranded positive-sense RNA viruses, a prototype being the tRNA-like structure (TLS) found at the 3' end of the turnip yellow mosaic virus (TYMV). This TLS not only acts like a tRNA to drive aminoacylation of the viral genomic (g)RNA, but also interacts with other structures in the 3' untranslated region of the gRNA, contains the promoter for negative-strand synthesis, and influences several infection-critical processes. TLS RNA can provide a glimpse into the structural basis of RNA multifunctionality and plasticity, but for decades its high-resolution structure has remained elusive. Here we present the crystal structure of the complete TYMV TLS to 2.0 A resolution. Globally, the RNA adopts a shape that mimics tRNA, but it uses a very different set of intramolecular interactions to achieve this shape. These interactions also allow the TLS to readily switch conformations. In addition, the TLS structure is 'two faced': one face closely mimics tRNA and drives aminoacylation, the other face diverges from tRNA and enables additional functionality. The TLS is thus structured to perform several functions and interact with diverse binding partners, and we demonstrate its ability to specifically bind to ribosomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136544/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136544/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colussi, Timothy M -- Costantino, David A -- Hammond, John A -- Ruehle, Grant M -- Nix, Jay C -- Kieft, Jeffrey S -- GM081346/GM/NIGMS NIH HHS/ -- GM097333/GM/NIGMS NIH HHS/ -- P30 CA046934/CA/NCI NIH HHS/ -- P30CA046934/CA/NCI NIH HHS/ -- R01 GM081346/GM/NIGMS NIH HHS/ -- R01 GM097333/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Jul 17;511(7509):366-9. doi: 10.1038/nature13378.

    Description: Sulphur is an essential element for life and is ubiquitous in living systems. Yet how the sulphur atom is incorporated into many sulphur-containing secondary metabolites is poorly understood. For bond formation between carbon and sulphur in primary metabolites, the major ionic sulphur sources are the persulphide and thiocarboxylate groups on sulphur-carrier (donor) proteins. Each group is post-translationally generated through the action of a specific activating enzyme. In all reported bacterial cases, the gene encoding the enzyme that catalyses the carbon-sulphur bond formation reaction and that encoding the cognate sulphur-carrier protein exist in the same gene cluster. To study the production of the 2-thiosugar moiety in BE-7585A, an antibiotic from Amycolatopsis orientalis, we identified a putative 2-thioglucose synthase, BexX, whose protein sequence and mode of action seem similar to those of ThiG, the enzyme that catalyses thiazole formation in thiamine biosynthesis. However, no gene encoding a sulphur-carrier protein could be located in the BE-7585A cluster. Subsequent genome sequencing uncovered a few genes encoding sulphur-carrier proteins that are probably involved in the biosynthesis of primary metabolites but only one activating enzyme gene in the A. orientalis genome. Further experiments showed that this activating enzyme can adenylate each of these sulphur-carrier proteins and probably also catalyses the subsequent thiolation, through its rhodanese domain. A proper combination of these sulphur-delivery systems is effective for BexX-catalysed 2-thioglucose production. The ability of BexX to selectively distinguish sulphur-carrier proteins is given a structural basis using X-ray crystallography. This study is, to our knowledge, the first complete characterization of thiosugar formation in nature and also demonstrates the receptor promiscuity of the A. orientalis sulphur-delivery system. Our results also show that co-opting the sulphur-delivery machinery of primary metabolism for the biosynthesis of sulphur-containing natural products is probably a general strategy found in nature.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4082789/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4082789/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sasaki, Eita -- Zhang, Xuan -- Sun, He G -- Lu, Mei-yeh Jade -- Liu, Tsung-lin -- Ou, Albert -- Li, Jeng-yi -- Chen, Yu-hsiang -- Ealick, Steven E -- Liu, Hung-wen -- DK67081/DK/NIDDK NIH HHS/ -- GM035906/GM/NIGMS NIH HHS/ -- GM103403/GM/NIGMS NIH HHS/ -- GM103485/GM/NIGMS NIH HHS/ -- P41 GM103403/GM/NIGMS NIH HHS/ -- P41 GM103485/GM/NIGMS NIH HHS/ -- R01 DK067081/DK/NIDDK NIH HHS/ -- R01 GM035906/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Jun 19;510(7505):427-31. doi: 10.1038/nature13256.

    Description: Evidence is mounting that the immense diversity of microorganisms and animals that live belowground contributes significantly to shaping aboveground biodiversity and the functioning of terrestrial ecosystems. Our understanding of how this belowground biodiversity is distributed, and how it regulates the structure and functioning of terrestrial ecosystems, is rapidly growing. Evidence also points to soil biodiversity as having a key role in determining the ecological and evolutionary responses of terrestrial ecosystems to current and future environmental change. Here we review recent progress and propose avenues for further research in this field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bardgett, Richard D -- van der Putten, Wim H -- England -- Nature. 2014 Nov 27;515(7528):505-11. doi: 10.1038/nature13855.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Life Sciences, Michael Smith Building, The University of Manchester, Manchester M13 9PT, United Kingdom. ; 1] Department of Terrestrial Ecology, Netherlands Institute of Ecology (NIOO-KNAW), PO Box 50, 6700 AB Wageningen, The Netherlands [2] Laboratory of Nematology, Wageningen University, PO Box 8123, 6700 ES Wageningen, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25428498" target="_blank"〉PubMed〈/a〉

    Description: We present the high-quality genome sequence of a approximately 45,000-year-old modern human male from Siberia. This individual derives from a population that lived before-or simultaneously with-the separation of the populations in western and eastern Eurasia and carries a similar amount of Neanderthal ancestry as present-day Eurasians. However, the genomic segments of Neanderthal ancestry are substantially longer than those observed in present-day individuals, indicating that Neanderthal gene flow into the ancestors of this individual occurred 7,000-13,000 years before he lived. We estimate an autosomal mutation rate of 0.4 x 10(-9) to 0.6 x 10(-9) per site per year, a Y chromosomal mutation rate of 0.7 x 10(-9) to 0.9 x 10(-9) per site per year based on the additional substitutions that have occurred in present-day non-Africans compared to this genome, and a mitochondrial mutation rate of 1.8 x 10(-8) to 3.2 x 10(-8) per site per year based on the age of the bone.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4753769/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4753769/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fu, Qiaomei -- Li, Heng -- Moorjani, Priya -- Jay, Flora -- Slepchenko, Sergey M -- Bondarev, Aleksei A -- Johnson, Philip L F -- Aximu-Petri, Ayinuer -- Prufer, Kay -- de Filippo, Cesare -- Meyer, Matthias -- Zwyns, Nicolas -- Salazar-Garcia, Domingo C -- Kuzmin, Yaroslav V -- Keates, Susan G -- Kosintsev, Pavel A -- Razhev, Dmitry I -- Richards, Michael P -- Peristov, Nikolai V -- Lachmann, Michael -- Douka, Katerina -- Higham, Thomas F G -- Slatkin, Montgomery -- Hublin, Jean-Jacques -- Reich, David -- Kelso, Janet -- Viola, T Bence -- Paabo, Svante -- F32 GM115006/GM/NIGMS NIH HHS/ -- GM100233/GM/NIGMS NIH HHS/ -- K99 GM104158/GM/NIGMS NIH HHS/ -- K99-GM104158/GM/NIGMS NIH HHS/ -- R01 GM100233/GM/NIGMS NIH HHS/ -- R01-GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Oct 23;514(7523):445-9. doi: 10.1038/nature13810.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, IVPP, CAS, Beijing 100044, China [2] Department of Evolutionary Genetics, Max Planck Institute for Evolutionary Anthropology, D-04103 Leipzig, Germany. ;

    Description: What mechanisms underlie the transitions responsible for the diverse shapes observed in the living world? Although bacteria exhibit a myriad of morphologies, the mechanisms responsible for the evolution of bacterial cell shape are not understood. We investigated morphological diversity in a group of bacteria that synthesize an appendage-like extension of the cell envelope called the stalk. The location and number of stalks varies among species, as exemplified by three distinct subcellular positions of stalks within a rod-shaped cell body: polar in the genus Caulobacter and subpolar or bilateral in the genus Asticcacaulis. Here we show that a developmental regulator of Caulobacter crescentus, SpmX, is co-opted in the genus Asticcacaulis to specify stalk synthesis either at the subpolar or bilateral positions. We also show that stepwise evolution of a specific region of SpmX led to the gain of a new function and localization of this protein, which drove the sequential transition in stalk positioning. Our results indicate that changes in protein function, co-option and modularity are key elements in the evolution of bacterial morphology. Therefore, similar evolutionary principles of morphological transitions apply to both single-celled prokaryotes and multicellular eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4035126/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4035126/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Chao -- Brown, Pamela J B -- Ducret, Adrien -- Brun, Yves V -- AI072992/AI/NIAID NIH HHS/ -- GM051986/GM/NIGMS NIH HHS/ -- R01 GM051986/GM/NIGMS NIH HHS/ -- S10RR028697-01/RR/NCRR NIH HHS/ -- England -- Nature. 2014 Feb 27;506(7489):489-93. doi: 10.1038/nature12900.

    Description: The TMEM16 family of proteins, also known as anoctamins, features a remarkable functional diversity. This family contains the long sought-after Ca(2+)-activated chloride channels as well as lipid scramblases and cation channels. Here we present the crystal structure of a TMEM16 family member from the fungus Nectria haematococca that operates as a Ca(2+)-activated lipid scramblase. Each subunit of the homodimeric protein contains ten transmembrane helices and a hydrophilic membrane-traversing cavity that is exposed to the lipid bilayer as a potential site of catalysis. This cavity harbours a conserved Ca(2+)-binding site located within the hydrophobic core of the membrane. Mutations of residues involved in Ca(2+) coordination affect both lipid scrambling in N. haematococca TMEM16 and ion conduction in the Cl(-) channel TMEM16A. The structure reveals the general architecture of the family and its mode of Ca(2+) activation. It also provides insight into potential scrambling mechanisms and serves as a framework to unravel the conduction of ions in certain TMEM16 proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brunner, Janine D -- Lim, Novandy K -- Schenck, Stephan -- Duerst, Alessia -- Dutzler, Raimund -- England -- Nature. 2014 Dec 11;516(7530):207-12. doi: 10.1038/nature13984.

    Description: Speciation generally involves a three-step process--range expansion, range fragmentation and the development of reproductive isolation between spatially separated populations. Speciation relies on cycling through these three steps and each may limit the rate at which new species form. We estimate phylogenetic relationships among all Himalayan songbirds to ask whether the development of reproductive isolation and ecological competition, both factors that limit range expansions, set an ultimate limit on speciation. Based on a phylogeny for all 358 species distributed along the eastern elevational gradient, here we show that body size and shape differences evolved early in the radiation, with the elevational band occupied by a species evolving later. These results are consistent with competition for niche space limiting species accumulation. Even the elevation dimension seems to be approaching ecological saturation, because the closest relatives both inside the assemblage and elsewhere in the Himalayas are on average separated by more than five million years, which is longer than it generally takes for reproductive isolation to be completed; also, elevational distributions are well explained by resource availability, notably the abundance of arthropods, and not by differences in diversification rates in different elevational zones. Our results imply that speciation rate is ultimately set by niche filling (that is, ecological competition for resources), rather than by the rate of acquisition of reproductive isolation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Price, Trevor D -- Hooper, Daniel M -- Buchanan, Caitlyn D -- Johansson, Ulf S -- Tietze, D Thomas -- Alstrom, Per -- Olsson, Urban -- Ghosh-Harihar, Mousumi -- Ishtiaq, Farah -- Gupta, Sandeep K -- Martens, Jochen -- Harr, Bettina -- Singh, Pratap -- Mohan, Dhananjai -- England -- Nature. 2014 May 8;509(7499):222-5. doi: 10.1038/nature13272.

    Description: The silkworm Bombyx mori uses a WZ sex determination system that is analogous to the one found in birds and some reptiles. In this system, males have two Z sex chromosomes, whereas females have Z and W sex chromosomes. The silkworm W chromosome has a dominant role in female determination, suggesting the existence of a dominant feminizing gene in this chromosome. However, the W chromosome is almost fully occupied by transposable element sequences, and no functional protein-coding gene has been identified so far. Female-enriched PIWI-interacting RNAs (piRNAs) are the only known transcripts that are produced from the sex-determining region of the W chromosome, but the function(s) of these piRNAs are unknown. Here we show that a W-chromosome-derived, female-specific piRNA is the feminizing factor of B. mori. This piRNA is produced from a piRNA precursor which we named Fem. Fem sequences were arranged in tandem in the sex-determining region of the W chromosome. Inhibition of Fem-derived piRNA-mediated signalling in female embryos led to the production of the male-specific splice variants of B. mori doublesex (Bmdsx), a gene which acts at the downstream end of the sex differentiation cascade. A target gene of Fem-derived piRNA was identified on the Z chromosome of B. mori. This gene, which we named Masc, encoded a CCCH-type zinc finger protein. We show that the silencing of Masc messenger RNA by Fem piRNA is required for the production of female-specific isoforms of Bmdsx in female embryos, and that Masc protein controls both dosage compensation and masculinization in male embryos. Our study characterizes a single small RNA that is responsible for primary sex determination in the WZ sex determination system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kiuchi, Takashi -- Koga, Hikaru -- Kawamoto, Munetaka -- Shoji, Keisuke -- Sakai, Hiroki -- Arai, Yuji -- Ishihara, Genki -- Kawaoka, Shinpei -- Sugano, Sumio -- Shimada, Toru -- Suzuki, Yutaka -- Suzuki, Masataka G -- Katsuma, Susumu -- England -- Nature. 2014 May 29;509(7502):633-6. doi: 10.1038/nature13315.

    Description: Efficient duplication of the genome requires the concerted action of helicase and DNA polymerases at replication forks to avoid stalling of the replication machinery and consequent genomic instability. In eukaryotes, the physical coupling between helicase and DNA polymerases remains poorly understood. Here we define the molecular mechanism by which the yeast Ctf4 protein links the Cdc45-MCM-GINS (CMG) DNA helicase to DNA polymerase alpha (Pol alpha) within the replisome. We use X-ray crystallography and electron microscopy to show that Ctf4 self-associates in a constitutive disk-shaped trimer. Trimerization depends on a beta-propeller domain in the carboxy-terminal half of the protein, which is fused to a helical extension that protrudes from one face of the trimeric disk. Critically, Pol alpha and the CMG helicase share a common mechanism of interaction with Ctf4. We show that the amino-terminal tails of the catalytic subunit of Pol alpha and the Sld5 subunit of GINS contain a conserved Ctf4-binding motif that docks onto the exposed helical extension of a Ctf4 protomer within the trimer. Accordingly, we demonstrate that one Ctf4 trimer can support binding of up to three partner proteins, including the simultaneous association with both Pol alpha and GINS. Our findings indicate that Ctf4 can couple two molecules of Pol alpha to one CMG helicase within the replisome, providing a new model for lagging-strand synthesis in eukaryotes that resembles the emerging model for the simpler replisome of Escherichia coli. The ability of Ctf4 to act as a platform for multivalent interactions illustrates a mechanism for the concurrent recruitment of factors that act together at the fork.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4059944/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4059944/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simon, Aline C -- Zhou, Jin C -- Perera, Rajika L -- van Deursen, Frederick -- Evrin, Cecile -- Ivanova, Marina E -- Kilkenny, Mairi L -- Renault, Ludovic -- Kjaer, Svend -- Matak-Vinkovic, Dijana -- Labib, Karim -- Costa, Alessandro -- Pellegrini, Luca -- 084279/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- England -- Nature. 2014 Jun 12;510(7504):293-7. doi: 10.1038/nature13234.

    Description: Recognition of modified histones by 'reader' proteins plays a critical role in the regulation of chromatin. H3K36 trimethylation (H3K36me3) is deposited onto the nucleosomes in the transcribed regions after RNA polymerase II elongation. In yeast, this mark in turn recruits epigenetic regulators to reset the chromatin to a relatively repressive state, thus suppressing cryptic transcription. However, much less is known about the role of H3K36me3 in transcription regulation in mammals. This is further complicated by the transcription-coupled incorporation of the histone variant H3.3 in gene bodies. Here we show that the candidate tumour suppressor ZMYND11 specifically recognizes H3K36me3 on H3.3 (H3.3K36me3) and regulates RNA polymerase II elongation. Structural studies show that in addition to the trimethyl-lysine binding by an aromatic cage within the PWWP domain, the H3.3-dependent recognition is mediated by the encapsulation of the H3.3-specific 'Ser 31' residue in a composite pocket formed by the tandem bromo-PWWP domains of ZMYND11. Chromatin immunoprecipitation followed by sequencing shows a genome-wide co-localization of ZMYND11 with H3K36me3 and H3.3 in gene bodies, and its occupancy requires the pre-deposition of H3.3K36me3. Although ZMYND11 is associated with highly expressed genes, it functions as an unconventional transcription co-repressor by modulating RNA polymerase II at the elongation stage. ZMYND11 is critical for the repression of a transcriptional program that is essential for tumour cell growth; low expression levels of ZMYND11 in breast cancer patients correlate with worse prognosis. Consistently, overexpression of ZMYND11 suppresses cancer cell growth in vitro and tumour formation in mice. Together, this study identifies ZMYND11 as an H3.3-specific reader of H3K36me3 that links the histone-variant-mediated transcription elongation control to tumour suppression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4142212/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4142212/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wen, Hong -- Li, Yuanyuan -- Xi, Yuanxin -- Jiang, Shiming -- Stratton, Sabrina -- Peng, Danni -- Tanaka, Kaori -- Ren, Yongfeng -- Xia, Zheng -- Wu, Jun -- Li, Bing -- Barton, Michelle C -- Li, Wei -- Li, Haitao -- Shi, Xiaobing -- CA016672/CA/NCI NIH HHS/ -- P30 CA016672/CA/NCI NIH HHS/ -- R01 GM090077/GM/NIGMS NIH HHS/ -- R01 HG007538/HG/NHGRI NIH HHS/ -- R01GM090077/GM/NIGMS NIH HHS/ -- R01HG007538/HG/NHGRI NIH HHS/ -- England -- Nature. 2014 Apr 10;508(7495):263-8. doi: 10.1038/nature13045.

    Description: In the ciliate Paramecium, transposable elements and their single-copy remnants are deleted during the development of somatic macronuclei from germline micronuclei, at each sexual generation. Deletions are targeted by scnRNAs, small RNAs produced from the germ line during meiosis that first scan the maternal macronuclear genome to identify missing sequences, and then allow the zygotic macronucleus to reproduce the same deletions. Here we show that this process accounts for the maternal inheritance of mating types in Paramecium tetraurelia, a long-standing problem in epigenetics. Mating type E depends on expression of the transmembrane protein mtA, and the default type O is determined during development by scnRNA-dependent excision of the mtA promoter. In the sibling species Paramecium septaurelia, mating type O is determined by coding-sequence deletions in a different gene, mtB, which is specifically required for mtA expression. These independently evolved mechanisms suggest frequent exaptation of the scnRNA pathway to regulate cellular genes and mediate transgenerational epigenetic inheritance of essential phenotypic polymorphisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Singh, Deepankar Pratap -- Saudemont, Baptiste -- Guglielmi, Gerard -- Arnaiz, Olivier -- Gout, Jean-Francois -- Prajer, Malgorzata -- Potekhin, Alexey -- Przybos, Ewa -- Aubusson-Fleury, Anne -- Bhullar, Simran -- Bouhouche, Khaled -- Lhuillier-Akakpo, Maoussi -- Tanty, Veronique -- Blugeon, Corinne -- Alberti, Adriana -- Labadie, Karine -- Aury, Jean-Marc -- Sperling, Linda -- Duharcourt, Sandra -- Meyer, Eric -- England -- Nature. 2014 May 22;509(7501):447-52. doi: 10.1038/nature13318.

    Description: Without an approved vaccine or treatments, Ebola outbreak management has been limited to palliative care and barrier methods to prevent transmission. These approaches, however, have yet to end the 2014 outbreak of Ebola after its prolonged presence in West Africa. Here we show that a combination of monoclonal antibodies (ZMapp), optimized from two previous antibody cocktails, is able to rescue 100% of rhesus macaques when treatment is initiated up to 5 days post-challenge. High fever, viraemia and abnormalities in blood count and blood chemistry were evident in many animals before ZMapp intervention. Advanced disease, as indicated by elevated liver enzymes, mucosal haemorrhages and generalized petechia could be reversed, leading to full recovery. ELISA and neutralizing antibody assays indicate that ZMapp is cross-reactive with the Guinean variant of Ebola. ZMapp exceeds the efficacy of any other therapeutics described so far, and results warrant further development of this cocktail for clinical use.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214273/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214273/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Qiu, Xiangguo -- Wong, Gary -- Audet, Jonathan -- Bello, Alexander -- Fernando, Lisa -- Alimonti, Judie B -- Fausther-Bovendo, Hugues -- Wei, Haiyan -- Aviles, Jenna -- Hiatt, Ernie -- Johnson, Ashley -- Morton, Josh -- Swope, Kelsi -- Bohorov, Ognian -- Bohorova, Natasha -- Goodman, Charles -- Kim, Do -- Pauly, Michael H -- Velasco, Jesus -- Pettitt, James -- Olinger, Gene G -- Whaley, Kevin -- Xu, Bianli -- Strong, James E -- Zeitlin, Larry -- Kobinger, Gary P -- U19 AI109762/AI/NIAID NIH HHS/ -- U19AI109762/AI/NIAID NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2014 Oct 2;514(7520):47-53. doi: 10.1038/nature13777.

    Description: The genetic architecture of autism spectrum disorder involves the interplay of common and rare variants and their impact on hundreds of genes. Using exome sequencing, here we show that analysis of rare coding variation in 3,871 autism cases and 9,937 ancestry-matched or parental controls implicates 22 autosomal genes at a false discovery rate (FDR) 〈 0.05, plus a set of 107 autosomal genes strongly enriched for those likely to affect risk (FDR 〈 0.30). These 107 genes, which show unusual evolutionary constraint against mutations, incur de novo loss-of-function mutations in over 5% of autistic subjects. Many of the genes implicated encode proteins for synaptic formation, transcriptional regulation and chromatin-remodelling pathways.

    Description: The origins of neural systems remain unresolved. In contrast to other basal metazoans, ctenophores (comb jellies) have both complex nervous and mesoderm-derived muscular systems. These holoplanktonic predators also have sophisticated ciliated locomotion, behaviour and distinct development. Here we present the draft genome of Pleurobrachia bachei, Pacific sea gooseberry, together with ten other ctenophore transcriptomes, and show that they are remarkably distinct from other animal genomes in their content of neurogenic, immune and developmental genes. Our integrative analyses place Ctenophora as the earliest lineage within Metazoa. This hypothesis is supported by comparative analysis of multiple gene families, including the apparent absence of HOX genes, canonical microRNA machinery, and reduced immune complement in ctenophores. Although two distinct nervous systems are well recognized in ctenophores, many bilaterian neuron-specific genes and genes of 'classical' neurotransmitter pathways either are absent or, if present, are not expressed in neurons. Our metabolomic and physiological data are consistent with the hypothesis that ctenophore neural systems, and possibly muscle specification, evolved independently from those in other animals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4337882/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4337882/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moroz, Leonid L -- Kocot, Kevin M -- Citarella, Mathew R -- Dosung, Sohn -- Norekian, Tigran P -- Povolotskaya, Inna S -- Grigorenko, Anastasia P -- Dailey, Christopher -- Berezikov, Eugene -- Buckley, Katherine M -- Ptitsyn, Andrey -- Reshetov, Denis -- Mukherjee, Krishanu -- Moroz, Tatiana P -- Bobkova, Yelena -- Yu, Fahong -- Kapitonov, Vladimir V -- Jurka, Jerzy -- Bobkov, Yuri V -- Swore, Joshua J -- Girardo, David O -- Fodor, Alexander -- Gusev, Fedor -- Sanford, Rachel -- Bruders, Rebecca -- Kittler, Ellen -- Mills, Claudia E -- Rast, Jonathan P -- Derelle, Romain -- Solovyev, Victor V -- Kondrashov, Fyodor A -- Swalla, Billie J -- Sweedler, Jonathan V -- Rogaev, Evgeny I -- Halanych, Kenneth M -- Kohn, Andrea B -- 1R01GM097502/GM/NIGMS NIH HHS/ -- 1S10RR027052/RR/NCRR NIH HHS/ -- 55007424/Howard Hughes Medical Institute/ -- 5R21DA030118/DA/NIDA NIH HHS/ -- P30 DA018310/DA/NIDA NIH HHS/ -- R01 AG029360/AG/NIA NIH HHS/ -- R01 GM097502/GM/NIGMS NIH HHS/ -- R01 MH097062/MH/NIMH NIH HHS/ -- R01MH097062/MH/NIMH NIH HHS/ -- R21 DA030118/DA/NIDA NIH HHS/ -- R21 RR025699/RR/NCRR NIH HHS/ -- R21RR025699/RR/NCRR NIH HHS/ -- S10 RR027052/RR/NCRR NIH HHS/ -- England -- Nature. 2014 Jun 5;510(7503):109-14. doi: 10.1038/nature13400.

    Description: Since the recognition that allopatric speciation can be induced by large-scale reconfigurations of the landscape that isolate formerly continuous populations, such as the separation of continents by plate tectonics, the uplift of mountains or the formation of large rivers, landscape change has been viewed as a primary driver of biological diversification. This process is referred to in biogeography as vicariance. In the most species-rich region of the world, the Neotropics, the sundering of populations associated with the Andean uplift is ascribed this principal role in speciation. An alternative model posits that rather than being directly linked to landscape change, allopatric speciation is initiated to a greater extent by dispersal events, with the principal drivers of speciation being organism-specific abilities to persist and disperse in the landscape. Landscape change is not a necessity for speciation in this model. Here we show that spatial and temporal patterns of genetic differentiation in Neotropical birds are highly discordant across lineages and are not reconcilable with a model linking speciation solely to landscape change. Instead, the strongest predictors of speciation are the amount of time a lineage has persisted in the landscape and the ability of birds to move through the landscape matrix. These results, augmented by the observation that most species-level diversity originated after episodes of major Andean uplift in the Neogene period, suggest that dispersal and differentiation on a matrix previously shaped by large-scale landscape events was a major driver of avian speciation in lowland Neotropical rainforests.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Brian Tilston -- McCormack, John E -- Cuervo, Andres M -- Hickerson, Michael J -- Aleixo, Alexandre -- Cadena, Carlos Daniel -- Perez-Eman, Jorge -- Burney, Curtis W -- Xie, Xiaoou -- Harvey, Michael G -- Faircloth, Brant C -- Glenn, Travis C -- Derryberry, Elizabeth P -- Prejean, Jesse -- Fields, Samantha -- Brumfield, Robb T -- England -- Nature. 2014 Nov 20;515(7527):406-9. doi: 10.1038/nature13687.

    Description: Variation in terrestrial net primary production (NPP) with climate is thought to originate from a direct influence of temperature and precipitation on plant metabolism. However, variation in NPP may also result from an indirect influence of climate by means of plant age, stand biomass, growing season length and local adaptation. To identify the relative importance of direct and indirect climate effects, we extend metabolic scaling theory to link hypothesized climate influences with NPP, and assess hypothesized relationships using a global compilation of ecosystem woody plant biomass and production data. Notably, age and biomass explained most of the variation in production whereas temperature and precipitation explained almost none, suggesting that climate indirectly (not directly) influences production. Furthermore, our theory shows that variation in NPP is characterized by a common scaling relationship, suggesting that global change models can incorporate the mechanisms governing this relationship to improve predictions of future ecosystem function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michaletz, Sean T -- Cheng, Dongliang -- Kerkhoff, Andrew J -- Enquist, Brian J -- England -- Nature. 2014 Aug 7;512(7512):39-43. doi: 10.1038/nature13470.

    Description: Zoonotic infectious diseases such as influenza continue to pose a grave threat to human health. However, the factors that mediate the emergence of RNA viruses such as influenza A virus (IAV) are still incompletely understood. Phylogenetic inference is crucial to reconstructing the origins and tracing the flow of IAV within and between hosts. Here we show that explicitly allowing IAV host lineages to have independent rates of molecular evolution is necessary for reliable phylogenetic inference of IAV and that methods that do not do so, including 'relaxed' molecular clock models, can be positively misleading. A phylogenomic analysis using a host-specific local clock model recovers extremely consistent evolutionary histories across all genomic segments and demonstrates that the equine H7N7 lineage is a sister clade to strains from birds--as well as those from humans, swine and the equine H3N8 lineage--sharing an ancestor with them in the mid to late 1800s. Moreover, major western and eastern hemisphere avian influenza lineages inferred for each gene coalesce in the late 1800s. On the basis of these phylogenies and the synchrony of these key nodes, we infer that the internal genes of avian influenza virus (AIV) underwent a global selective sweep beginning in the late 1800s, a process that continued throughout the twentieth century and up to the present. The resulting western hemispheric AIV lineage subsequently contributed most of the genomic segments to the 1918 pandemic virus and, independently, the 1963 equine H3N8 panzootic lineage. This approach provides a clear resolution of evolutionary patterns and processes in IAV, including the flow of viral genes and genomes within and between host lineages.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4098125/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4098125/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worobey, Michael -- Han, Guan-Zhu -- Rambaut, Andrew -- 092807/Wellcome Trust/United Kingdom -- 095831/Wellcome Trust/United Kingdom -- R01 AI084691/AI/NIAID NIH HHS/ -- R01AI084691/AI/NIAID NIH HHS/ -- England -- Nature. 2014 Apr 10;508(7495):254-7. doi: 10.1038/nature13016.

    Description: The human immunodeficiency virus (HIV)-1 protein Vif has a central role in the neutralization of host innate defences by hijacking cellular proteasomal degradation pathways to subvert the antiviral activity of host restriction factors; however, the underlying mechanism by which Vif achieves this remains unclear. Here we report a crystal structure of the Vif-CBF-beta-CUL5-ELOB-ELOC complex. The structure reveals that Vif, by means of two domains, organizes formation of the pentameric complex by interacting with CBF-beta, CUL5 and ELOC. The larger domain (alpha/beta domain) of Vif binds to the same side of CBF-beta as RUNX1, indicating that Vif and RUNX1 are exclusive for CBF-beta binding. Interactions of the smaller domain (alpha-domain) of Vif with ELOC and CUL5 are cooperative and mimic those of SOCS2 with the latter two proteins. A unique zinc-finger motif of Vif, which is located between the two Vif domains, makes no contacts with the other proteins but stabilizes the conformation of the alpha-domain, which may be important for Vif-CUL5 interaction.

    Description: One of the most striking examples of sexual dimorphism is sex-limited mimicry in butterflies, a phenomenon in which one sex--usually the female--mimics a toxic model species, whereas the other sex displays a different wing pattern. Sex-limited mimicry is phylogenetically widespread in the swallowtail butterfly genus Papilio, in which it is often associated with female mimetic polymorphism. In multiple polymorphic species, the entire wing pattern phenotype is controlled by a single Mendelian 'supergene'. Although theoretical work has explored the evolutionary dynamics of supergene mimicry, there are almost no empirical data that address the critical issue of what a mimicry supergene actually is at a functional level. Using an integrative approach combining genetic and association mapping, transcriptome and genome sequencing, and gene expression analyses, we show that a single gene, doublesex, controls supergene mimicry in Papilio polytes. This is in contrast to the long-held view that supergenes are likely to be controlled by a tightly linked cluster of loci. Analysis of gene expression and DNA sequence variation indicates that isoform expression differences contribute to the functional differences between dsx mimicry alleles, and protein sequence evolution may also have a role. Our results combine elements from different hypotheses for the identity of supergenes, showing that a single gene can switch the entire wing pattern among mimicry phenotypes but may require multiple, tightly linked mutations to do so.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kunte, K -- Zhang, W -- Tenger-Trolander, A -- Palmer, D H -- Martin, A -- Reed, R D -- Mullen, S P -- Kronforst, M R -- England -- Nature. 2014 Mar 13;507(7491):229-32. doi: 10.1038/nature13112.

    Description: The study of cancer genes in mouse models has traditionally relied on genetically-engineered strains made via transgenesis or gene targeting in embryonic stem cells. Here we describe a new method of cancer model generation using the CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR-associated proteins) system in vivo in wild-type mice. We used hydrodynamic injection to deliver a CRISPR plasmid DNA expressing Cas9 and single guide RNAs (sgRNAs) to the liver that directly target the tumour suppressor genes Pten (ref. 5) and p53 (also known as TP53 and Trp53) (ref. 6), alone and in combination. CRISPR-mediated Pten mutation led to elevated Akt phosphorylation and lipid accumulation in hepatocytes, phenocopying the effects of deletion of the gene using Cre-LoxP technology. Simultaneous targeting of Pten and p53 induced liver tumours that mimicked those caused by Cre-loxP-mediated deletion of Pten and p53. DNA sequencing of liver and tumour tissue revealed insertion or deletion mutations of the tumour suppressor genes, including bi-allelic mutations of both Pten and p53 in tumours. Furthermore, co-injection of Cas9 plasmids harbouring sgRNAs targeting the beta-catenin gene and a single-stranded DNA oligonucleotide donor carrying activating point mutations led to the generation of hepatocytes with nuclear localization of beta-catenin. This study demonstrates the feasibility of direct mutation of tumour suppressor genes and oncogenes in the liver using the CRISPR/Cas system, which presents a new avenue for rapid development of liver cancer models and functional genomics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4199937/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4199937/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Wen -- Chen, Sidi -- Yin, Hao -- Tammela, Tuomas -- Papagiannakopoulos, Thales -- Joshi, Nikhil S -- Cai, Wenxin -- Yang, Gillian -- Bronson, Roderick -- Crowley, Denise G -- Zhang, Feng -- Anderson, Daniel G -- Sharp, Phillip A -- Jacks, Tyler -- 1K99CA169512/CA/NCI NIH HHS/ -- 2-P01-CA42063/CA/NCI NIH HHS/ -- 5-U54-CA151884-04/CA/NCI NIH HHS/ -- DP1 MH100706/MH/NIMH NIH HHS/ -- K99 CA169512/CA/NCI NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- R00 CA169512/CA/NCI NIH HHS/ -- R01 DK097768/DK/NIDDK NIH HHS/ -- R01-CA115527/CA/NCI NIH HHS/ -- R01-CA132091/CA/NCI NIH HHS/ -- R01-CA133404/CA/NCI NIH HHS/ -- R01-EB000244/EB/NIBIB NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Oct 16;514(7522):380-4. doi: 10.1038/nature13589.

    Description: Soil contains more carbon than the atmosphere and vegetation combined. Understanding the mechanisms controlling the accumulation and stability of soil carbon is critical to predicting the Earth's future climate. Recent studies suggest that decomposition of soil organic matter is often limited by nitrogen availability to microbes and that plants, via their fungal symbionts, compete directly with free-living decomposers for nitrogen. Ectomycorrhizal and ericoid mycorrhizal (EEM) fungi produce nitrogen-degrading enzymes, allowing them greater access to organic nitrogen sources than arbuscular mycorrhizal (AM) fungi. This leads to the theoretical prediction that soil carbon storage is greater in ecosystems dominated by EEM fungi than in those dominated by AM fungi. Using global data sets, we show that soil in ecosystems dominated by EEM-associated plants contains 70% more carbon per unit nitrogen than soil in ecosystems dominated by AM-associated plants. The effect of mycorrhizal type on soil carbon is independent of, and of far larger consequence than, the effects of net primary production, temperature, precipitation and soil clay content. Hence the effect of mycorrhizal type on soil carbon content holds at the global scale. This finding links the functional traits of mycorrhizal fungi to carbon storage at ecosystem-to-global scales, suggesting that plant-decomposer competition for nutrients exerts a fundamental control over the terrestrial carbon cycle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Averill, Colin -- Turner, Benjamin L -- Finzi, Adrien C -- England -- Nature. 2014 Jan 23;505(7484):543-5. doi: 10.1038/nature12901.

    Description: The emergence of jawed vertebrates (gnathostomes) from jawless vertebrates was accompanied by major morphological and physiological innovations, such as hinged jaws, paired fins and immunoglobulin-based adaptive immunity. Gnathostomes subsequently diverged into two groups, the cartilaginous fishes and the bony vertebrates. Here we report the whole-genome analysis of a cartilaginous fish, the elephant shark (Callorhinchus milii). We find that the C. milii genome is the slowest evolving of all known vertebrates, including the 'living fossil' coelacanth, and features extensive synteny conservation with tetrapod genomes, making it a good model for comparative analyses of gnathostome genomes. Our functional studies suggest that the lack of genes encoding secreted calcium-binding phosphoproteins in cartilaginous fishes explains the absence of bone in their endoskeleton. Furthermore, the adaptive immune system of cartilaginous fishes is unusual: it lacks the canonical CD4 co-receptor and most transcription factors, cytokines and cytokine receptors related to the CD4 lineage, despite the presence of polymorphic major histocompatibility complex class II molecules. It thus presents a new model for understanding the origin of adaptive immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3964593/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3964593/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Venkatesh, Byrappa -- Lee, Alison P -- Ravi, Vydianathan -- Maurya, Ashish K -- Lian, Michelle M -- Swann, Jeremy B -- Ohta, Yuko -- Flajnik, Martin F -- Sutoh, Yoichi -- Kasahara, Masanori -- Hoon, Shawn -- Gangu, Vamshidhar -- Roy, Scott W -- Irimia, Manuel -- Korzh, Vladimir -- Kondrychyn, Igor -- Lim, Zhi Wei -- Tay, Boon-Hui -- Tohari, Sumanty -- Kong, Kiat Whye -- Ho, Shufen -- Lorente-Galdos, Belen -- Quilez, Javier -- Marques-Bonet, Tomas -- Raney, Brian J -- Ingham, Philip W -- Tay, Alice -- Hillier, LaDeana W -- Minx, Patrick -- Boehm, Thomas -- Wilson, Richard K -- Brenner, Sydney -- Warren, Wesley C -- AI27877/AI/NIAID NIH HHS/ -- R01 AI027877/AI/NIAID NIH HHS/ -- R01 OD010549/OD/NIH HHS/ -- RR006603/RR/NCRR NIH HHS/ -- U41 HG002371/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- England -- Nature. 2014 Jan 9;505(7482):174-9. doi: 10.1038/nature12826.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Comparative Genomics Laboratory, Institute of Molecular and Cell Biology, A*STAR, Biopolis, Singapore 138673 [2] Department of Paediatrics, Yong Loo Lin School of Medicine, National University of Singapore, Singapore 119228. ; Comparative Genomics Laboratory, Institute of Molecular and Cell Biology, A*STAR, Biopolis, Singapore 138673. ; Developmental and Biomedical Genetics Laboratory, Institute of Molecular and Cell Biology, A*STAR, Biopolis, Singapore 138673. ; Department of Developmental Immunology, Max-Planck-Institute of Immunobiology and Epigenetics, Stuebeweg 51, 79108 Freiburg, Germany. ; Department of Microbiology and Immunology, University of Maryland, Baltimore, Maryland 21201, USA. ; Department of Pathology, Hokkaido University Graduate School of Medicine, Sapporo 060-8638, Japan. ; Molecular Engineering Laboratory, Biomedical Sciences Institutes, A*STAR, Biopolis, Singapore 138673. ; Department of Biology, San Francisco State University, San Francisco, California 94132, USA. ; Banting and Best Department of Medical Research and Donnelly Centre, University of Toronto, Toronto, Ontario M5S 3E1, Canada. ; Fish Developmental Biology Laboratory, Institute of Molecular and Cell Biology, A*STAR, Biopolis, Singapore 138673. ; 1] Institut de Biologia Evolutiva (UPF-CSIC), PRBB, 08003 Barcelona, Spain [2] Institucio Catalana de Recerca i Estudis Avancats (ICREA), 08010 Barcelona, Catalonia, Spain. ; Center for Biomolecular Science and Engineering, School of Engineering, University of California Santa Cruz, Santa Cruz, California 95064, USA. ; The Genome Institute at Washington University, St Louis, Missouri 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24402279" target="_blank"〉PubMed〈/a〉

    Description: Programmed -1 ribosomal frameshift (-1 PRF) signals redirect translating ribosomes to slip back one base on messenger RNAs. Although well characterized in viruses, how these elements may regulate cellular gene expression is not understood. Here we describe a -1 PRF signal in the human mRNA encoding CCR5, the HIV-1 co-receptor. CCR5 mRNA-mediated -1 PRF is directed by an mRNA pseudoknot, and is stimulated by at least two microRNAs. Mapping the mRNA-miRNA interaction suggests that formation of a triplex RNA structure stimulates -1 PRF. A -1 PRF event on the CCR5 mRNA directs translating ribosomes to a premature termination codon, destabilizing it through the nonsense-mediated mRNA decay pathway. At least one additional mRNA decay pathway is also involved. Functional -1 PRF signals that seem to be regulated by miRNAs are also demonstrated in mRNAs encoding six other cytokine receptors, suggesting a novel mode through which immune responses may be fine-tuned in mammalian cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4369343/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4369343/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Belew, Ashton Trey -- Meskauskas, Arturas -- Musalgaonkar, Sharmishtha -- Advani, Vivek M -- Sulima, Sergey O -- Kasprzak, Wojciech K -- Shapiro, Bruce A -- Dinman, Jonathan D -- 5 R01GM058859/GM/NIGMS NIH HHS/ -- HHSN261200800001/PHS HHS/ -- R01 GM058859/GM/NIGMS NIH HHS/ -- R01 HL119439/HL/NHLBI NIH HHS/ -- R21 GM068123/GM/NIGMS NIH HHS/ -- R21GM068123/GM/NIGMS NIH HHS/ -- T32 AI051967/AI/NIAID NIH HHS/ -- T32AI051967/AI/NIAID NIH HHS/ -- T32GM080201/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2014 Aug 21;512(7514):265-9. doi: 10.1038/nature13429.

    Description: The human X and Y chromosomes evolved from an ordinary pair of autosomes, but millions of years ago genetic decay ravaged the Y chromosome, and only three per cent of its ancestral genes survived. We reconstructed the evolution of the Y chromosome across eight mammals to identify biases in gene content and the selective pressures that preserved the surviving ancestral genes. Our findings indicate that survival was nonrandom, and in two cases, convergent across placental and marsupial mammals. We conclude that the gene content of the Y chromosome became specialized through selection to maintain the ancestral dosage of homologous X-Y gene pairs that function as broadly expressed regulators of transcription, translation and protein stability. We propose that beyond its roles in testis determination and spermatogenesis, the Y chromosome is essential for male viability, and has unappreciated roles in Turner's syndrome and in phenotypic differences between the sexes in health and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4139287/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4139287/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bellott, Daniel W -- Hughes, Jennifer F -- Skaletsky, Helen -- Brown, Laura G -- Pyntikova, Tatyana -- Cho, Ting-Jan -- Koutseva, Natalia -- Zaghlul, Sara -- Graves, Tina -- Rock, Susie -- Kremitzki, Colin -- Fulton, Robert S -- Dugan, Shannon -- Ding, Yan -- Morton, Donna -- Khan, Ziad -- Lewis, Lora -- Buhay, Christian -- Wang, Qiaoyan -- Watt, Jennifer -- Holder, Michael -- Lee, Sandy -- Nazareth, Lynne -- Alfoldi, Jessica -- Rozen, Steve -- Muzny, Donna M -- Warren, Wesley C -- Gibbs, Richard A -- Wilson, Richard K -- Page, David C -- P51 RR013986/RR/NCRR NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Apr 24;508(7497):494-9. doi: 10.1038/nature13206.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute, Howard Hughes Medical Institute, & Department of Biology, Massachusetts Institute of Technology, Cambridge, Massachusetts 02142, USA. ; The Genome Institute, Washington University School of Medicine, St. Louis, Missouri 63108, USA. ; Human Genome Sequencing Center, Baylor College of Medicine, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24759411" target="_blank"〉PubMed〈/a〉

    Description: Female mosquitoes are major vectors of human disease and the most dangerous are those that preferentially bite humans. A 'domestic' form of the mosquito Aedes aegypti has evolved to specialize in biting humans and is the main worldwide vector of dengue, yellow fever, and chikungunya viruses. The domestic form coexists with an ancestral, 'forest' form that prefers to bite non-human animals and is found along the coast of Kenya. We collected the two forms, established laboratory colonies, and document striking divergence in preference for human versus non-human animal odour. We further show that the evolution of preference for human odour in domestic mosquitoes is tightly linked to increases in the expression and ligand-sensitivity of the odorant receptor AaegOr4, which we found recognizes a compound present at high levels in human odour. Our results provide a rare example of a gene contributing to behavioural evolution and provide insight into how disease-vectoring mosquitoes came to specialize on humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4286346/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4286346/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McBride, Carolyn S -- Baier, Felix -- Omondi, Aman B -- Spitzer, Sarabeth A -- Lutomiah, Joel -- Sang, Rosemary -- Ignell, Rickard -- Vosshall, Leslie B -- 5UL1TR000043/TR/NCATS NIH HHS/ -- HHSN272200900039C/AI/NIAID NIH HHS/ -- HHSN272200900039C/PHS HHS/ -- K99 DC012069/DC/NIDCD NIH HHS/ -- R00 DC012069/DC/NIDCD NIH HHS/ -- UL1 TR000043/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Nov 13;515(7526):222-7. doi: 10.1038/nature13964.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Laboratory of Neurogenetics and Behavior, The Rockefeller University, New York, New York 10065, USA [2] Howard Hughes Medical Institute, 1230 York Avenue, New York, New York 10065, USA. ; Laboratory of Neurogenetics and Behavior, The Rockefeller University, New York, New York 10065, USA. ; Unit of Chemical Ecology, Department of Plant Protection Biology, Swedish University of Agricultural Sciences, Box 102, Sundsvagen 14, 230 53 Alnarp, Sweden. ; Center for Virus Research, Kenya Medical Research Institute, PO Box 54840 - 00200, Off Mbagathi Way, Nairobi, Kenya.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25391959" target="_blank"〉PubMed〈/a〉

    Description: Permafrost contains about 50% of the global soil carbon. It is thought that the thawing of permafrost can lead to a loss of soil carbon in the form of methane and carbon dioxide emissions. The magnitude of the resulting positive climate feedback of such greenhouse gas emissions is still unknown and may to a large extent depend on the poorly understood role of microbial community composition in regulating the metabolic processes that drive such ecosystem-scale greenhouse gas fluxes. Here we show that changes in vegetation and increasing methane emissions with permafrost thaw are associated with a switch from hydrogenotrophic to partly acetoclastic methanogenesis, resulting in a large shift in the delta(13)C signature (10-15 per thousand) of emitted methane. We used a natural landscape gradient of permafrost thaw in northern Sweden as a model to investigate the role of microbial communities in regulating methane cycling, and to test whether a knowledge of community dynamics could improve predictions of carbon emissions under loss of permafrost. Abundance of the methanogen Candidatus 'Methanoflorens stordalenmirensis' is a key predictor of the shifts in methane isotopes, which in turn predicts the proportions of carbon emitted as methane and as carbon dioxide, an important factor for simulating the climate feedback associated with permafrost thaw in global models. By showing that the abundance of key microbial lineages can be used to predict atmospherically relevant patterns in methane isotopes and the proportion of carbon metabolized to methane during permafrost thaw, we establish a basis for scaling changing microbial communities to ecosystem isotope dynamics. Our findings indicate that microbial ecology may be important in ecosystem-scale responses to global change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCalley, Carmody K -- Woodcroft, Ben J -- Hodgkins, Suzanne B -- Wehr, Richard A -- Kim, Eun-Hae -- Mondav, Rhiannon -- Crill, Patrick M -- Chanton, Jeffrey P -- Rich, Virginia I -- Tyson, Gene W -- Saleska, Scott R -- England -- Nature. 2014 Oct 23;514(7523):478-81. doi: 10.1038/nature13798.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, USA. ; Australian Centre for Ecogenomics, School of Chemistry and Molecular Biosciences, University of Queensland, Brisbane 4072, Queensland, Australia. ; Department of Earth, Ocean and Atmospheric Science, Florida State University, Tallahassee, Florida 32306, USA. ; Department of Soil, Water and Environmental Science, University of Arizona, Tucson, Arizona 85721, USA. ; Department of Geological Sciences, Stockholm University, Stockholm 106 91, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25341787" target="_blank"〉PubMed〈/a〉

    Description: The land and ocean act as a sink for fossil-fuel emissions, thereby slowing the rise of atmospheric carbon dioxide concentrations. Although the uptake of carbon by oceanic and terrestrial processes has kept pace with accelerating carbon dioxide emissions until now, atmospheric carbon dioxide concentrations exhibit a large variability on interannual timescales, considered to be driven primarily by terrestrial ecosystem processes dominated by tropical rainforests. We use a terrestrial biogeochemical model, atmospheric carbon dioxide inversion and global carbon budget accounting methods to investigate the evolution of the terrestrial carbon sink over the past 30 years, with a focus on the underlying mechanisms responsible for the exceptionally large land carbon sink reported in 2011 (ref. 2). Here we show that our three terrestrial carbon sink estimates are in good agreement and support the finding of a 2011 record land carbon sink. Surprisingly, we find that the global carbon sink anomaly was driven by growth of semi-arid vegetation in the Southern Hemisphere, with almost 60 per cent of carbon uptake attributed to Australian ecosystems, where prevalent La Nina conditions caused up to six consecutive seasons of increased precipitation. In addition, since 1981, a six per cent expansion of vegetation cover over Australia was associated with a fourfold increase in the sensitivity of continental net carbon uptake to precipitation. Our findings suggest that the higher turnover rates of carbon pools in semi-arid biomes are an increasingly important driver of global carbon cycle inter-annual variability and that tropical rainforests may become less relevant drivers in the future. More research is needed to identify to what extent the carbon stocks accumulated during wet years are vulnerable to rapid decomposition or loss through fire in subsequent years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poulter, Benjamin -- Frank, David -- Ciais, Philippe -- Myneni, Ranga B -- Andela, Niels -- Bi, Jian -- Broquet, Gregoire -- Canadell, Josep G -- Chevallier, Frederic -- Liu, Yi Y -- Running, Steven W -- Sitch, Stephen -- van der Werf, Guido R -- England -- Nature. 2014 May 29;509(7502):600-3. doi: 10.1038/nature13376.

    Description: Thirty years ago it was shown that the non-enzymatic, template-directed polymerization of activated mononucleotides proceeds readily in a homochiral system, but is severely inhibited by the presence of the opposing enantiomer. This finding poses a severe challenge for the spontaneous emergence of RNA-based life, and has led to the suggestion that either RNA was preceded by some other genetic polymer that is not subject to chiral inhibition or chiral symmetry was broken through chemical processes before the origin of RNA-based life. Once an RNA enzyme arose that could catalyse the polymerization of RNA, it would have been possible to distinguish among the two enantiomers, enabling RNA replication and RNA-based evolution to occur. It is commonly thought that the earliest RNA polymerase and its substrates would have been of the same handedness, but this is not necessarily the case. Replicating D- and L-RNA molecules may have emerged together, based on the ability of structured RNAs of one handedness to catalyse the templated polymerization of activated mononucleotides of the opposite handedness. Here we develop such a cross-chiral RNA polymerase, using in vitro evolution starting from a population of random-sequence RNAs. The D-RNA enzyme, consisting of 83 nucleotides, catalyses the joining of L-mono- or oligonucleotide substrates on a complementary L-RNA template, and similar behaviour occurs for the L-enzyme with D-substrates and a D-template. Chiral inhibition is avoided because the 10(6)-fold rate acceleration of the enzyme only pertains to cross-chiral substrates. The enzyme's activity is sufficient to generate full-length copies of its enantiomer through the templated joining of 11 component oligonucleotides.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4239201/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4239201/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sczepanski, Jonathan T -- Joyce, Gerald F -- F32 GM101741/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Nov 20;515(7527):440-2. doi: 10.1038/nature13900.

    Description: The impacts of escalating wildfire in many regions - the lives and homes lost, the expense of suppression and the damage to ecosystem services - necessitate a more sustainable coexistence with wildfire. Climate change and continued development on fire-prone landscapes will only compound current problems. Emerging strategies for managing ecosystems and mitigating risks to human communities provide some hope, although greater recognition of their inherent variation and links is crucial. Without a more integrated framework, fire will never operate as a natural ecosystem process, and the impact on society will continue to grow. A more coordinated approach to risk management and land-use planning in these coupled systems is needed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moritz, Max A -- Batllori, Enric -- Bradstock, Ross A -- Gill, A Malcolm -- Handmer, John -- Hessburg, Paul F -- Leonard, Justin -- McCaffrey, Sarah -- Odion, Dennis C -- Schoennagel, Tania -- Syphard, Alexandra D -- England -- Nature. 2014 Nov 6;515(7525):58-66. doi: 10.1038/nature13946.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Environmental Science, Policy, and Management, Division of Ecosystem Sciences, University of California, Berkeley, 130 Mulford Hall, Berkeley, California 94720, USA. ; 1] Department of Environmental Science, Policy, and Management, Division of Ecosystem Sciences, University of California, Berkeley, 130 Mulford Hall, Berkeley, California 94720, USA.

    Description: The response of the terrestrial carbon cycle to climate change is among the largest uncertainties affecting future climate change projections. The feedback between the terrestrial carbon cycle and climate is partly determined by changes in the turnover time of carbon in land ecosystems, which in turn is an ecosystem property that emerges from the interplay between climate, soil and vegetation type. Here we present a global, spatially explicit and observation-based assessment of whole-ecosystem carbon turnover times that combines new estimates of vegetation and soil organic carbon stocks and fluxes. We find that the overall mean global carbon turnover time is 23(+7)(-4) years (95 per cent confidence interval). On average, carbon resides in the vegetation and soil near the Equator for a shorter time than at latitudes north of 75 degrees north (mean turnover times of 15 and 255 years, respectively). We identify a clear dependence of the turnover time on temperature, as expected from our present understanding of temperature controls on ecosystem dynamics. Surprisingly, our analysis also reveals a similarly strong association between turnover time and precipitation. Moreover, we find that the ecosystem carbon turnover times simulated by state-of-the-art coupled climate/carbon-cycle models vary widely and that numerical simulations, on average, tend to underestimate the global carbon turnover time by 36 per cent. The models show stronger spatial relationships with temperature than do observation-based estimates, but generally do not reproduce the strong relationships with precipitation and predict faster carbon turnover in many semi-arid regions. Our findings suggest that future climate/carbon-cycle feedbacks may depend more strongly on changes in the hydrological cycle than is expected at present and is considered in Earth system models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carvalhais, Nuno -- Forkel, Matthias -- Khomik, Myroslava -- Bellarby, Jessica -- Jung, Martin -- Migliavacca, Mirco -- Mu, Mingquan -- Saatchi, Sassan -- Santoro, Maurizio -- Thurner, Martin -- Weber, Ulrich -- Ahrens, Bernhard -- Beer, Christian -- Cescatti, Alessandro -- Randerson, James T -- Reichstein, Markus -- England -- Nature. 2014 Oct 9;514(7521):213-7. doi: 10.1038/nature13731.

    Description: Observations of a longer growing season through earlier plant growth in temperate to polar regions have been thought to be a response to climate warming. However, data from experimental warming studies indicate that many species that initiate leaf growth and flowering earlier also reach seed maturation and senesce earlier, shortening their active and reproductive periods. A conceptual model to explain this apparent contradiction, and an analysis of the effect of elevated CO2--which can delay annual life cycle events--on changing season length, have not been tested. Here we show that experimental warming in a temperate grassland led to a longer growing season through earlier leaf emergence by the first species to leaf, often a grass, and constant or delayed senescence by other species that were the last to senesce, supporting the conceptual model. Elevated CO2 further extended growing, but not reproductive, season length in the warmed grassland by conserving water, which enabled most species to remain active longer. Our results suggest that a longer growing season, especially in years or biomes where water is a limiting factor, is not due to warming alone, but also to higher atmospheric CO2 concentrations that extend the active period of plant annual life cycles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reyes-Fox, Melissa -- Steltzer, Heidi -- Trlica, M J -- McMaster, Gregory S -- Andales, Allan A -- LeCain, Dan R -- Morgan, Jack A -- England -- Nature. 2014 Jun 12;510(7504):259-62. doi: 10.1038/nature13207.

    Description: Clovis, with its distinctive biface, blade and osseous technologies, is the oldest widespread archaeological complex defined in North America, dating from 11,100 to 10,700 (14)C years before present (bp) (13,000 to 12,600 calendar years bp). Nearly 50 years of archaeological research point to the Clovis complex as having developed south of the North American ice sheets from an ancestral technology. However, both the origins and the genetic legacy of the people who manufactured Clovis tools remain under debate. It is generally believed that these people ultimately derived from Asia and were directly related to contemporary Native Americans. An alternative, Solutrean, hypothesis posits that the Clovis predecessors emigrated from southwestern Europe during the Last Glacial Maximum. Here we report the genome sequence of a male infant (Anzick-1) recovered from the Anzick burial site in western Montana. The human bones date to 10,705 +/- 35 (14)C years bp (approximately 12,707-12,556 calendar years bp) and were directly associated with Clovis tools. We sequenced the genome to an average depth of 14.4x and show that the gene flow from the Siberian Upper Palaeolithic Mal'ta population into Native American ancestors is also shared by the Anzick-1 individual and thus happened before 12,600 years bp. We also show that the Anzick-1 individual is more closely related to all indigenous American populations than to any other group. Our data are compatible with the hypothesis that Anzick-1 belonged to a population directly ancestral to many contemporary Native Americans. Finally, we find evidence of a deep divergence in Native American populations that predates the Anzick-1 individual.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rasmussen, Morten -- Anzick, Sarah L -- Waters, Michael R -- Skoglund, Pontus -- DeGiorgio, Michael -- Stafford, Thomas W Jr -- Rasmussen, Simon -- Moltke, Ida -- Albrechtsen, Anders -- Doyle, Shane M -- Poznik, G David -- Gudmundsdottir, Valborg -- Yadav, Rachita -- Malaspinas, Anna-Sapfo -- White, Samuel Stockton 5th -- Allentoft, Morten E -- Cornejo, Omar E -- Tambets, Kristiina -- Eriksson, Anders -- Heintzman, Peter D -- Karmin, Monika -- Korneliussen, Thorfinn Sand -- Meltzer, David J -- Pierre, Tracey L -- Stenderup, Jesper -- Saag, Lauri -- Warmuth, Vera M -- Lopes, Margarida C -- Malhi, Ripan S -- Brunak, Soren -- Sicheritz-Ponten, Thomas -- Barnes, Ian -- Collins, Matthew -- Orlando, Ludovic -- Balloux, Francois -- Manica, Andrea -- Gupta, Ramneek -- Metspalu, Mait -- Bustamante, Carlos D -- Jakobsson, Mattias -- Nielsen, Rasmus -- Willerslev, Eske -- BB/H005854/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/H008802/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- P25032/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2014 Feb 13;506(7487):225-9. doi: 10.1038/nature13025.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Centre for GeoGenetics, Natural History Museum of Denmark, University of Copenhagen, Oster Voldgade 5-7, DK-1350 Copenhagen K, Denmark [2]. ; 1] Anzick Family, 31 Old Clyde Park Road, Livingston, Montana 59047, USA [2]. ; Center for the Study of the First Americans, Departments of Anthropology and Geography, Texas A&M University, 4352 TAMU, College Station, Texas 77843-4352, USA. ; Department of Evolutionary Biology, Uppsala University, Norbyvagen 18D, 752 36 Uppsala, Sweden. ; 1] Department of Integrative Biology, University of California, Berkeley, 4134 Valley Life Sciences Building, Berkeley, California 94720, USA [2] Earth Sciences Department, Natural History Museum, Cromwell Road, London SW7 5BD, UK (I.B.); Department of Biology, Pennsylvania State University, 502 Wartik Laboratory, University Park, Pennsylvania 16802, USA (M.D.). ; 1] Centre for GeoGenetics, Natural History Museum of Denmark, University of Copenhagen, Oster Voldgade 5-7, DK-1350 Copenhagen K, Denmark [2] AMS 14C Dating Centre, Department of Physics & Astronomy, University of Aarhus, Ny Munkegade 120, DK-8000 Aarhus C, Denmark. ; Center for Biological Sequence Analysis, Department of Systems Biology, Technical University of Denmark, Kemitorvet 208, Kgs.

    Description: In line with global targets agreed under the Convention on Biological Diversity, the number of marine protected areas (MPAs) is increasing rapidly, yet socio-economic benefits generated by MPAs remain difficult to predict and under debate. MPAs often fail to reach their full potential as a consequence of factors such as illegal harvesting, regulations that legally allow detrimental harvesting, or emigration of animals outside boundaries because of continuous habitat or inadequate size of reserve. Here we show that the conservation benefits of 87 MPAs investigated worldwide increase exponentially with the accumulation of five key features: no take, well enforced, old (〉10 years), large (〉100 km(2)), and isolated by deep water or sand. Using effective MPAs with four or five key features as an unfished standard, comparisons of underwater survey data from effective MPAs with predictions based on survey data from fished coasts indicate that total fish biomass has declined about two-thirds from historical baselines as a result of fishing. Effective MPAs also had twice as many large (〉250 mm total length) fish species per transect, five times more large fish biomass, and fourteen times more shark biomass than fished areas. Most (59%) of the MPAs studied had only one or two key features and were not ecologically distinguishable from fished sites. Our results show that global conservation targets based on area alone will not optimize protection of marine biodiversity. More emphasis is needed on better MPA design, durable management and compliance to ensure that MPAs achieve their desired conservation value.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Edgar, Graham J -- Stuart-Smith, Rick D -- Willis, Trevor J -- Kininmonth, Stuart -- Baker, Susan C -- Banks, Stuart -- Barrett, Neville S -- Becerro, Mikel A -- Bernard, Anthony T F -- Berkhout, Just -- Buxton, Colin D -- Campbell, Stuart J -- Cooper, Antonia T -- Davey, Marlene -- Edgar, Sophie C -- Forsterra, Gunter -- Galvan, David E -- Irigoyen, Alejo J -- Kushner, David J -- Moura, Rodrigo -- Parnell, P Ed -- Shears, Nick T -- Soler, German -- Strain, Elisabeth M A -- Thomson, Russell J -- England -- Nature. 2014 Feb 13;506(7487):216-20. doi: 10.1038/nature13022.

    Description: Methane (CH4) is an important greenhouse gas because it has 25 times the global warming potential of carbon dioxide (CO2) by mass over a century. Recent calculations suggest that atmospheric CH4 emissions have been responsible for approximately 20% of Earth's warming since pre-industrial times. Understanding how CH4 emissions from ecosystems will respond to expected increases in global temperature is therefore fundamental to predicting whether the carbon cycle will mitigate or accelerate climate change. Methanogenesis is the terminal step in the remineralization of organic matter and is carried out by strictly anaerobic Archaea. Like most other forms of metabolism, methanogenesis is temperature-dependent. However, it is not yet known how this physiological response combines with other biotic processes (for example, methanotrophy, substrate supply, microbial community composition) and abiotic processes (for example, water-table depth) to determine the temperature dependence of ecosystem-level CH4 emissions. It is also not known whether CH4 emissions at the ecosystem level have a fundamentally different temperature dependence than other key fluxes in the carbon cycle, such as photosynthesis and respiration. Here we use meta-analyses to show that seasonal variations in CH4 emissions from a wide range of ecosystems exhibit an average temperature dependence similar to that of CH4 production derived from pure cultures of methanogens and anaerobic microbial communities. This average temperature dependence (0.96 electron volts (eV)), which corresponds to a 57-fold increase between 0 and 30 degrees C, is considerably higher than previously observed for respiration (approximately 0.65 eV) and photosynthesis (approximately 0.3 eV). As a result, we show that both the emission of CH4 and the ratio of CH4 to CO2 emissions increase markedly with seasonal increases in temperature. Our findings suggest that global warming may have a large impact on the relative contributions of CO2 and CH4 to total greenhouse gas emissions from aquatic ecosystems, terrestrial wetlands and rice paddies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yvon-Durocher, Gabriel -- Allen, Andrew P -- Bastviken, David -- Conrad, Ralf -- Gudasz, Cristian -- St-Pierre, Annick -- Thanh-Duc, Nguyen -- del Giorgio, Paul A -- England -- Nature. 2014 Mar 27;507(7493):488-91. doi: 10.1038/nature13164.

    Description: A well-balanced human diet includes a significant intake of non-starch polysaccharides, collectively termed 'dietary fibre', from the cell walls of diverse fruits and vegetables. Owing to the paucity of alimentary enzymes encoded by the human genome, our ability to derive energy from dietary fibre depends on the saccharification and fermentation of complex carbohydrates by the massive microbial community residing in our distal gut. The xyloglucans (XyGs) are a ubiquitous family of highly branched plant cell wall polysaccharides whose mechanism(s) of degradation in the human gut and consequent importance in nutrition have been unclear. Here we demonstrate that a single, complex gene locus in Bacteroides ovatus confers XyG catabolism in this common colonic symbiont. Through targeted gene disruption, biochemical analysis of all predicted glycoside hydrolases and carbohydrate-binding proteins, and three-dimensional structural determination of the vanguard endo-xyloglucanase, we reveal the molecular mechanisms through which XyGs are hydrolysed to component monosaccharides for further metabolism. We also observe that orthologous XyG utilization loci (XyGULs) serve as genetic markers of XyG catabolism in Bacteroidetes, that XyGULs are restricted to a limited number of phylogenetically diverse strains, and that XyGULs are ubiquitous in surveyed human metagenomes. Our findings reveal that the metabolism of even highly abundant components of dietary fibre may be mediated by niche species, which has immediate fundamental and practical implications for gut symbiont population ecology in the context of human diet, nutrition and health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4282169/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4282169/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larsbrink, Johan -- Rogers, Theresa E -- Hemsworth, Glyn R -- McKee, Lauren S -- Tauzin, Alexandra S -- Spadiut, Oliver -- Klinter, Stefan -- Pudlo, Nicholas A -- Urs, Karthik -- Koropatkin, Nicole M -- Creagh, A Louise -- Haynes, Charles A -- Kelly, Amelia G -- Cederholm, Stefan Nilsson -- Davies, Gideon J -- Martens, Eric C -- Brumer, Harry -- BB/I014802/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- DK084214/DK/NIDDK NIH HHS/ -- GM099513/GM/NIGMS NIH HHS/ -- K01 DK084214/DK/NIDDK NIH HHS/ -- R01 GM099513/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Feb 27;506(7489):498-502. doi: 10.1038/nature12907.

    Description: Cytosine residues in mammalian DNA occur in five forms: cytosine (C), 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC). The ten-eleven translocation (Tet) dioxygenases convert 5mC to 5hmC, 5fC and 5caC in three consecutive, Fe(II)- and alpha-ketoglutarate-dependent oxidation reactions. The Tet family of dioxygenases is widely distributed across the tree of life, including in the heterolobosean amoeboflagellate Naegleria gruberi. The genome of Naegleria encodes homologues of mammalian DNA methyltransferase and Tet proteins. Here we study biochemically and structurally one of the Naegleria Tet-like proteins (NgTet1), which shares significant sequence conservation (approximately 14% identity or 39% similarity) with mammalian Tet1. Like mammalian Tet proteins, NgTet1 acts on 5mC and generates 5hmC, 5fC and 5caC. The crystal structure of NgTet1 in complex with DNA containing a 5mCpG site revealed that NgTet1 uses a base-flipping mechanism to access 5mC. The DNA is contacted from the minor groove and bent towards the major groove. The flipped 5mC is positioned in the active-site pocket with planar stacking contacts, Watson-Crick polar hydrogen bonds and van der Waals interactions specific for 5mC. The sequence conservation between NgTet1 and mammalian Tet1, including residues involved in structural integrity and functional significance, suggests structural conservation across phyla.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4364404/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4364404/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hashimoto, Hideharu -- Pais, June E -- Zhang, Xing -- Saleh, Lana -- Fu, Zheng-Qing -- Dai, Nan -- Correa, Ivan R Jr -- Zheng, Yu -- Cheng, Xiaodong -- GM049245/GM/NIGMS NIH HHS/ -- GM095209/GM/NIGMS NIH HHS/ -- GM105132/GM/NIGMS NIH HHS/ -- R01 GM049245/GM/NIGMS NIH HHS/ -- R44 GM105132/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Feb 20;506(7488):391-5. doi: 10.1038/nature12905.

    Description: The isolation of human monoclonal antibodies is providing important insights into the specificities that underlie broad neutralization of HIV-1 (reviewed in ref. 1). Here we report a broad and extremely potent HIV-specific monoclonal antibody, termed 35O22, which binds a novel HIV-1 envelope glycoprotein (Env) epitope. 35O22 neutralized 62% of 181 pseudoviruses with a half-maximum inhibitory concentration (IC50) 〈50 mug ml(-1). The median IC50 of neutralized viruses was 0.033 mug ml(-1), among the most potent thus far described. 35O22 did not bind monomeric forms of Env tested, but did bind the trimeric BG505 SOSIP.664. Mutagenesis and a reconstruction by negative-stain electron microscopy of the Fab in complex with trimer revealed that it bound to a conserved epitope, which stretched across gp120 and gp41. The specificity of 35O22 represents a novel site of vulnerability on HIV Env, which serum analysis indicates to be commonly elicited by natural infection. Binding to this new site of vulnerability may thus be an important complement to current monoclonal-antibody-based approaches to immunotherapies, prophylaxis and vaccine design.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224615/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224615/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Jinghe -- Kang, Byong H -- Pancera, Marie -- Lee, Jeong Hyun -- Tong, Tommy -- Feng, Yu -- Imamichi, Hiromi -- Georgiev, Ivelin S -- Chuang, Gwo-Yu -- Druz, Aliaksandr -- Doria-Rose, Nicole A -- Laub, Leo -- Sliepen, Kwinten -- van Gils, Marit J -- de la Pena, Alba Torrents -- Derking, Ronald -- Klasse, Per-Johan -- Migueles, Stephen A -- Bailer, Robert T -- Alam, Munir -- Pugach, Pavel -- Haynes, Barton F -- Wyatt, Richard T -- Sanders, Rogier W -- Binley, James M -- Ward, Andrew B -- Mascola, John R -- Kwong, Peter D -- Connors, Mark -- 280829/European Research Council/International -- AI84714/AI/NIAID NIH HHS/ -- AI93278/AI/NIAID NIH HHS/ -- P01 AI082362/AI/NIAID NIH HHS/ -- R01 AI100790/AI/NIAID NIH HHS/ -- UM1 AI100645/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- ZIA AI000855-15/Intramural NIH HHS/ -- ZIA AI001090-05/Intramural NIH HHS/ -- England -- Nature. 2014 Nov 6;515(7525):138-42. doi: 10.1038/nature13601.

    Description: UvrD helicase is required for nucleotide excision repair, although its role in this process is not well defined. Here we show that Escherichia coli UvrD binds RNA polymerase during transcription elongation and, using its helicase/translocase activity, forces RNA polymerase to slide backward along DNA. By inducing backtracking, UvrD exposes DNA lesions shielded by blocked RNA polymerase, allowing nucleotide excision repair enzymes to gain access to sites of damage. Our results establish UvrD as a bona fide transcription elongation factor that contributes to genomic integrity by resolving conflicts between transcription and DNA repair complexes. Furthermore, we show that the elongation factor NusA cooperates with UvrD in coupling transcription to DNA repair by promoting backtracking and recruiting nucleotide excision repair enzymes to exposed lesions. Because backtracking is a shared feature of all cellular RNA polymerases, we propose that this mechanism enables RNA polymerases to function as global DNA damage scanners in bacteria and eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4471481/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4471481/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epshtein, Vitaly -- Kamarthapu, Venu -- McGary, Katelyn -- Svetlov, Vladimir -- Ueberheide, Beatrix -- Proshkin, Sergey -- Mironov, Alexander -- Nudler, Evgeny -- R01 GM058750/GM/NIGMS NIH HHS/ -- T32 GM088118/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Jan 16;505(7483):372-7. doi: 10.1038/nature12928.

    Description: Gibbons are small arboreal apes that display an accelerated rate of evolutionary chromosomal rearrangement and occupy a key node in the primate phylogeny between Old World monkeys and great apes. Here we present the assembly and analysis of a northern white-cheeked gibbon (Nomascus leucogenys) genome. We describe the propensity for a gibbon-specific retrotransposon (LAVA) to insert into chromosome segregation genes and alter transcription by providing a premature termination site, suggesting a possible molecular mechanism for the genome plasticity of the gibbon lineage. We further show that the gibbon genera (Nomascus, Hylobates, Hoolock and Symphalangus) experienced a near-instantaneous radiation approximately 5 million years ago, coincident with major geographical changes in southeast Asia that caused cycles of habitat compression and expansion. Finally, we identify signatures of positive selection in genes important for forelimb development (TBX5) and connective tissues (COL1A1) that may have been involved in the adaptation of gibbons to their arboreal habitat.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4249732/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4249732/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carbone, Lucia -- Harris, R Alan -- Gnerre, Sante -- Veeramah, Krishna R -- Lorente-Galdos, Belen -- Huddleston, John -- Meyer, Thomas J -- Herrero, Javier -- Roos, Christian -- Aken, Bronwen -- Anaclerio, Fabio -- Archidiacono, Nicoletta -- Baker, Carl -- Barrell, Daniel -- Batzer, Mark A -- Beal, Kathryn -- Blancher, Antoine -- Bohrson, Craig L -- Brameier, Markus -- Campbell, Michael S -- Capozzi, Oronzo -- Casola, Claudio -- Chiatante, Giorgia -- Cree, Andrew -- Damert, Annette -- de Jong, Pieter J -- Dumas, Laura -- Fernandez-Callejo, Marcos -- Flicek, Paul -- Fuchs, Nina V -- Gut, Ivo -- Gut, Marta -- Hahn, Matthew W -- Hernandez-Rodriguez, Jessica -- Hillier, LaDeana W -- Hubley, Robert -- Ianc, Bianca -- Izsvak, Zsuzsanna -- Jablonski, Nina G -- Johnstone, Laurel M -- Karimpour-Fard, Anis -- Konkel, Miriam K -- Kostka, Dennis -- Lazar, Nathan H -- Lee, Sandra L -- Lewis, Lora R -- Liu, Yue -- Locke, Devin P -- Mallick, Swapan -- Mendez, Fernando L -- Muffato, Matthieu -- Nazareth, Lynne V -- Nevonen, Kimberly A -- O'Bleness, Majesta -- Ochis, Cornelia -- Odom, Duncan T -- Pollard, Katherine S -- Quilez, Javier -- Reich, David -- Rocchi, Mariano -- Schumann, Gerald G -- Searle, Stephen -- Sikela, James M -- Skollar, Gabriella -- Smit, Arian -- Sonmez, Kemal -- ten Hallers, Boudewijn -- Terhune, Elizabeth -- Thomas, Gregg W C -- Ullmer, Brygg -- Ventura, Mario -- Walker, Jerilyn A -- Wall, Jeffrey D -- Walter, Lutz -- Ward, Michelle C -- Wheelan, Sarah J -- Whelan, Christopher W -- White, Simon -- Wilhelm, Larry J -- Woerner, August E -- Yandell, Mark -- Zhu, Baoli -- Hammer, Michael F -- Marques-Bonet, Tomas -- Eichler, Evan E -- Fulton, Lucinda -- Fronick, Catrina -- Muzny, Donna M -- Warren, Wesley C -- Worley, Kim C -- Rogers, Jeffrey -- Wilson, Richard K -- Gibbs, Richard A -- 095908/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 260372/European Research Council/International -- HG002385/HG/NHGRI NIH HHS/ -- P30 AA019355/AA/NIAAA NIH HHS/ -- P30CA006973/CA/NCI NIH HHS/ -- P51 RR000163/RR/NCRR NIH HHS/ -- R01 GM059290/GM/NIGMS NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002385/HG/NHGRI NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 HG005226/HG/NHGRI NIH HHS/ -- R01 MH081203/MH/NIMH NIH HHS/ -- R01_HG005226/HG/NHGRI NIH HHS/ -- T15 LM007088/LM/NLM NIH HHS/ -- U41 HG007497/HG/NHGRI NIH HHS/ -- U41 HG007497-01/HG/NHGRI NIH HHS/ -- U41HG007234/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54HG003273/HG/NHGRI NIH HHS/ -- WT095908/Wellcome Trust/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Sep 11;513(7517):195-201. doi: 10.1038/nature13679.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Oregon Health &Science University, Department of Behavioral Neuroscience, 3181 SW Sam Jackson Park Road Portland, Oregon 97239, USA.

    Description: Emerging infectious diseases (EIDs) pose a risk to human welfare, both directly and indirectly, by affecting managed livestock and wildlife that provide valuable resources and ecosystem services, such as the pollination of crops. Honeybees (Apis mellifera), the prevailing managed insect crop pollinator, suffer from a range of emerging and exotic high-impact pathogens, and population maintenance requires active management by beekeepers to control them. Wild pollinators such as bumblebees (Bombus spp.) are in global decline, one cause of which may be pathogen spillover from managed pollinators like honeybees or commercial colonies of bumblebees. Here we use a combination of infection experiments and landscape-scale field data to show that honeybee EIDs are indeed widespread infectious agents within the pollinator assemblage. The prevalence of deformed wing virus (DWV) and the exotic parasite Nosema ceranae in honeybees and bumblebees is linked; as honeybees have higher DWV prevalence, and sympatric bumblebees and honeybees are infected by the same DWV strains, Apis is the likely source of at least one major EID in wild pollinators. Lessons learned from vertebrates highlight the need for increased pathogen control in managed bee species to maintain wild pollinators, as declines in native pollinators may be caused by interspecies pathogen transmission originating from managed pollinators.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3985068/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3985068/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Furst, M A -- McMahon, D P -- Osborne, J L -- Paxton, R J -- Brown, M J F -- 094888/Wellcome Trust/United Kingdom -- BB/I000097/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I000100/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I000151/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2014 Feb 20;506(7488):364-6. doi: 10.1038/nature12977.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Royal Holloway University of London, School of Biological Sciences, Bourne Building, Egham TW20 0EX, UK [2] IST Austria (Institute of Science and Technology Austria), 3400 Klosterneuburg, Austria. ; Queen's University Belfast, School of Biological Sciences, 97 Lisburn Road, Belfast BT9 7BL, UK. ; 1] Rothamsted Research, Department of Agro-Ecology, Harpenden AL5 2JQ, UK [2] University of Exeter, Environment & Sustainability Institute, Penryn TR10 9EZ, UK. ; 1] Queen's University Belfast, School of Biological Sciences, 97 Lisburn Road, Belfast BT9 7BL, UK [2] Martin-Luther-Universitat Halle-Wittenberg, Institute for Biology/General Zoology, Hoher Weg 8, 06120 Halle (Saale), Germany [3] German Centre for Integrative Biodiversity Research (iDiv), Halle-Jena-Leipzig, Deutscher Platz 5e, 04103 Leipzig, Germany. ; Royal Holloway University of London, School of Biological Sciences, Bourne Building, Egham TW20 0EX, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24553241" target="_blank"〉PubMed〈/a〉

    Description: Post-translational histone modifications have a critical role in regulating transcription, the cell cycle, DNA replication and DNA damage repair. The identification of new histone modifications critical for transcriptional regulation at initiation, elongation or termination is of particular interest. Here we report a new layer of regulation in transcriptional elongation that is conserved from yeast to mammals. This regulation is based on the phosphorylation of a highly conserved tyrosine residue, Tyr 57, in histone H2A and is mediated by the unsuspected tyrosine kinase activity of casein kinase 2 (CK2). Mutation of Tyr 57 in H2A in yeast or inhibition of CK2 activity impairs transcriptional elongation in yeast as well as in mammalian cells. Genome-wide binding analysis reveals that CK2alpha, the catalytic subunit of CK2, binds across RNA-polymerase-II-transcribed coding genes and active enhancers. Mutation of Tyr 57 causes a loss of H2B mono-ubiquitination as well as H3K4me3 and H3K79me3, histone marks associated with active transcription. Mechanistically, both CK2 inhibition and the H2A(Y57F) mutation enhance H2B deubiquitination activity of the Spt-Ada-Gcn5 acetyltransferase (SAGA) complex, suggesting a critical role of this phosphorylation in coordinating the activity of the SAGA complex during transcription. Together, these results identify a new component of regulation in transcriptional elongation based on CK2-dependent tyrosine phosphorylation of the globular domain of H2A.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4461219/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4461219/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Basnet, Harihar -- Su, Xue B -- Tan, Yuliang -- Meisenhelder, Jill -- Merkurjev, Daria -- Ohgi, Kenneth A -- Hunter, Tony -- Pillus, Lorraine -- Rosenfeld, Michael G -- CA173903/CA/NCI NIH HHS/ -- CA82683/CA/NCI NIH HHS/ -- DK018477/DK/NIDDK NIH HHS/ -- DK039949/DK/NIDDK NIH HHS/ -- GM033279/GM/NIGMS NIH HHS/ -- HL065445/HL/NHLBI NIH HHS/ -- NS034934/NS/NINDS NIH HHS/ -- P30 CA023100/CA/NCI NIH HHS/ -- R01 DK018477/DK/NIDDK NIH HHS/ -- R01 GM033279/GM/NIGMS NIH HHS/ -- R01 HL065445/HL/NHLBI NIH HHS/ -- R01 NS034934/NS/NINDS NIH HHS/ -- R37 DK039949/DK/NIDDK NIH HHS/ -- T32 DK007541/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Dec 11;516(7530):267-71. doi: 10.1038/nature13736.

    Description: Environmental constraints severely restrict crop yields in most production environments, and expanding the use of variation will underpin future progress in breeding. In semi-arid environments boron toxicity constrains productivity, and genetic improvement is the only effective strategy for addressing the problem. Wheat breeders have sought and used available genetic diversity from landraces to maintain yield in these environments; however, the identity of the genes at the major tolerance loci was unknown. Here we describe the identification of near-identical, root-specific boron transporter genes underlying the two major-effect quantitative trait loci for boron tolerance in wheat, Bo1 and Bo4 (ref. 2). We show that tolerance to a high concentration of boron is associated with multiple genomic changes including tetraploid introgression, dispersed gene duplication, and variation in gene structure and transcript level. An allelic series was identified from a panel of bread and durum wheat cultivars and landraces originating from diverse agronomic zones. Our results demonstrate that, during selection, breeders have matched functionally different boron tolerance alleles to specific environments. The characterization of boron tolerance in wheat illustrates the power of the new wheat genomic resources to define key adaptive processes that have underpinned crop improvement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pallotta, Margaret -- Schnurbusch, Thorsten -- Hayes, Julie -- Hay, Alison -- Baumann, Ute -- Paull, Jeff -- Langridge, Peter -- Sutton, Tim -- England -- Nature. 2014 Oct 2;514(7520):88-91. doi: 10.1038/nature13538.
