    [Perspective] How to break down crystalline cellulose (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-05-27
    Description: Biomass-degrading microorganisms use lytic polysaccharide monooxygenase (LPMO) enzymes to help digest cellulose, chitin, and starch. By cleaving otherwise inaccessible crystalline cellulose chains, these enzymes provide access to hydrolytic enzymes. LPMOs are of interest to biotechnology because efficient depolymerization of cellulose is a major bottleneck for the production of biologically based chemicals and fuels. On page 1098 of this issue, Kracher et al. (1) compare LPMO-reducing substrates in fungi from different taxonomic groups and lifestyles, based on both biochemical and genomic evidence. The results provide insights into reductive activation of LPMO that are important for developing more efficient industrial enzymes for lignocellulose biorefineries. Author: Angel T. Martínez

    The Chlamydomonas genome reveals the evolution of key animal and plant functions (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-13
    Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" 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/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉

    Climate-driven basin-scale decadal oscillations of oceanic phytoplankton (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: Phytoplankton--the microalgae that populate the upper lit layers of the ocean--fuel the oceanic food web and affect oceanic and atmospheric carbon dioxide levels through photosynthetic carbon fixation. Here, we show that multidecadal changes in global phytoplankton abundances are related to basin-scale oscillations of the physical ocean, specifically the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation. This relationship is revealed in approximately 20 years of satellite observations of chlorophyll and sea surface temperature. Interaction between the main pycnocline and the upper ocean seasonal mixed layer is one mechanism behind this correlation. Our findings provide a context for the interpretation of contemporary changes in global phytoplankton and should improve predictions of their future evolution with climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez, Elodie -- Antoine, David -- D'Ortenzio, Fabrizio -- Gentili, Bernard -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1253-6. doi: 10.1126/science.1177012.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UPMC University of Paris 06, UMR 7093, Laboratoire d'Oceanographie de Villefranche (LOV), 06230 Villefranche-sur-Mer, France. martinez@obs-vlfr.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965473" target="_blank"〉PubMed〈/a〉

    The Palomero genome suggests metal effects on domestication (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: Maize domestication (Zea mays ssp. mays L.) resulted in a wide diversity of native landraces that represent an invaluable source of genetic information for exploring natural variation and genome evolution. We sequenced de novo the approximately 2-gigabase genome of the Mexican landrace Palomero Toluqueno (Palomero) and compared its features to those of the modern inbred line B73. We revealed differences concordant with its ancient origin and identified chromosomal regions of low nucleotide variability that contain domestication genes involved in heavy-metal detoxification. Our results indicate that environmental changes were important selective forces acting on maize domestication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vielle-Calzada, Jean-Philippe -- Martinez de la Vega, Octavio -- Hernandez-Guzman, Gustavo -- Ibarra-Laclette, Enrique -- Alvarez-Mejia, Cesar -- Vega-Arreguin, Julio C -- Jimenez-Moraila, Beatriz -- Fernandez-Cortes, Araceli -- Corona-Armenta, Guillermo -- Herrera-Estrella, Luis -- Herrera-Estrella, Alfredo -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1078. doi: 10.1126/science.1178437.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratorio Nacional de Genomica para la Biodiversidad, CINVESTAV Irapuato, Km 9.6 Libramiento Norte Carretera Irapuato-Leon, 36500 Irapuato, Mexico.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965420" target="_blank"〉PubMed〈/a〉

    Cellodextrin transport in yeast for improved biofuel production (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-09-11
    Description: Fungal degradation of plant biomass may provide insights for improving cellulosic biofuel production. We show that the model cellulolytic fungus Neurospora crassa relies on a high-affinity cellodextrin transport system for rapid growth on cellulose. Reconstitution of the N. crassa cellodextrin transport system in Saccharomyces cerevisiae promotes efficient growth of this yeast on cellodextrins. In simultaneous saccharification and fermentation experiments, the engineered yeast strains more rapidly convert cellulose to ethanol when compared with yeast lacking this system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Galazka, Jonathan M -- Tian, Chaoguang -- Beeson, William T -- Martinez, Bruno -- Glass, N Louise -- Cate, Jamie H D -- New York, N.Y. -- Science. 2010 Oct 1;330(6000):84-6. doi: 10.1126/science.1192838.

    The protein kinase complement of the human genome (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-12-10
    Description: We have catalogued the protein kinase complement of the human genome (the "kinome") using public and proprietary genomic, complementary DNA, and expressed sequence tag (EST) sequences. This provides a starting point for comprehensive analysis of protein phosphorylation in normal and disease states, as well as a detailed view of the current state of human genome analysis through a focus on one large gene family. We identify 518 putative protein kinase genes, of which 71 have not previously been reported or described as kinases, and we extend or correct the protein sequences of 56 more kinases. New genes include members of well-studied families as well as previously unidentified families, some of which are conserved in model organisms. Classification and comparison with model organism kinomes identified orthologous groups and highlighted expansions specific to human and other lineages. We also identified 106 protein kinase pseudogenes. Chromosomal mapping revealed several small clusters of kinase genes and revealed that 244 kinases map to disease loci or cancer amplicons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Manning, G -- Whyte, D B -- Martinez, R -- Hunter, T -- Sudarsanam, S -- New York, N.Y. -- Science. 2002 Dec 6;298(5600):1912-34.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉SUGEN Inc., 230 East Grand Avenue, South San Francisco, CA 94080, USA. gerard-manning@sugen.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12471243" target="_blank"〉PubMed〈/a〉

    Imaging CF3I conical intersection and photodissociation dynamics with ultrafast electron diffraction (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-07-06
    Description: Conical intersections play a critical role in excited-state dynamics of polyatomic molecules because they govern the reaction pathways of many nonadiabatic processes. However, ultrafast probes have lacked sufficient spatial resolution to image wave-packet trajectories through these intersections directly. Here, we present the simultaneous experimental characterization of one-photon and two-photon excitation channels in isolated CF 3 I molecules using ultrafast gas-phase electron diffraction. In the two-photon channel, we have mapped out the real-space trajectories of a coherent nuclear wave packet, which bifurcates onto two potential energy surfaces when passing through a conical intersection. In the one-photon channel, we have resolved excitation of both the umbrella and the breathing vibrational modes in the CF 3 fragment in multiple nuclear dimensions. These findings benchmark and validate ab initio nonadiabatic dynamics calculations.

    Community genomics among stratified microbial assemblages in the ocean's interior (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-28
    Description: Microbial life predominates in the ocean, yet little is known about its genomic variability, especially along the depth continuum. We report here genomic analyses of planktonic microbial communities in the North Pacific Subtropical Gyre, from the ocean's surface to near-sea floor depths. Sequence variation in microbial community genes reflected vertical zonation of taxonomic groups, functional gene repertoires, and metabolic potential. The distributional patterns of microbial genes suggested depth-variable community trends in carbon and energy metabolism, attachment and motility, gene mobility, and host-viral interactions. Comparative genomic analyses of stratified microbial communities have the potential to provide significant insight into higher-order community organization and dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DeLong, Edward F -- Preston, Christina M -- Mincer, Tracy -- Rich, Virginia -- Hallam, Steven J -- Frigaard, Niels-Ulrik -- Martinez, Asuncion -- Sullivan, Matthew B -- Edwards, Robert -- Brito, Beltran Rodriguez -- Chisholm, Sallie W -- Karl, David M -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):496-503.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, Cambridge, MA 02139, USA. delong@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16439655" target="_blank"〉PubMed〈/a〉

    Five-vertebrate ChIP-seq reveals the evolutionary dynamics of transcription factor binding (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-10
    Description: Transcription factors (TFs) direct gene expression by binding to DNA regulatory regions. To explore the evolution of gene regulation, we used chromatin immunoprecipitation with high-throughput sequencing (ChIP-seq) to determine experimentally the genome-wide occupancy of two TFs, CCAAT/enhancer-binding protein alpha and hepatocyte nuclear factor 4 alpha, in the livers of five vertebrates. Although each TF displays highly conserved DNA binding preferences, most binding is species-specific, and aligned binding events present in all five species are rare. Regions near genes with expression levels that are dependent on a TF are often bound by the TF in multiple species yet show no enhanced DNA sequence constraint. Binding divergence between species can be largely explained by sequence changes to the bound motifs. Among the binding events lost in one lineage, only half are recovered by another binding event within 10 kilobases. Our results reveal large interspecies differences in transcriptional regulation and provide insight into regulatory evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" 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/PMC3008766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmidt, Dominic -- Wilson, Michael D -- Ballester, Benoit -- Schwalie, Petra C -- Brown, Gordon D -- Marshall, Aileen -- Kutter, Claudia -- Watt, Stephen -- Martinez-Jimenez, Celia P -- Mackay, Sarah -- Talianidis, Iannis -- Flicek, Paul -- Odom, Duncan T -- 062023/Wellcome Trust/United Kingdom -- 079643/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- WT062023/Wellcome Trust/United Kingdom -- WT079643/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2010 May 21;328(5981):1036-40. doi: 10.1126/science.1186176.

    Iron fertilization of the Subantarctic ocean during the last ice age (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-22
    Description: John H. Martin, who discovered widespread iron limitation of ocean productivity, proposed that dust-borne iron fertilization of Southern Ocean phytoplankton caused the ice age reduction in atmospheric carbon dioxide (CO2). In a sediment core from the Subantarctic Atlantic, we measured foraminifera-bound nitrogen isotopes to reconstruct ice age nitrate consumption, burial fluxes of iron, and proxies for productivity. Peak glacial times and millennial cold events are characterized by increases in dust flux, productivity, and the degree of nitrate consumption; this combination is uniquely consistent with Subantarctic iron fertilization. The associated strengthening of the Southern Ocean's biological pump can explain the lowering of CO2 at the transition from mid-climate states to full ice age conditions as well as the millennial-scale CO2 oscillations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez-Garcia, Alfredo -- Sigman, Daniel M -- Ren, Haojia -- Anderson, Robert F -- Straub, Marietta -- Hodell, David A -- Jaccard, Samuel L -- Eglinton, Timothy I -- Haug, Gerald H -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1347-50. doi: 10.1126/science.1246848.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geological Institute, ETH Zurich, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653031" target="_blank"〉PubMed〈/a〉
