    Description: The three-dimensional molecular structure of DNA, specifically the shape of the backbone and grooves of genomic DNA, can be dramatically affected by nucleotide changes, which can cause differences in protein-binding affinity and phenotype. We developed an algorithm to measure constraint on the basis of similarity of DNA topography among multiple species, using hydroxyl radical cleavage patterns to interrogate the solvent-accessible surface area of DNA. This algorithm found that 12% of bases in the human genome are evolutionarily constrained-double the number detected by nucleotide sequence-based algorithms. Topography-informed constrained regions correlated with functional noncoding elements, including enhancers, better than did regions identified solely on the basis of nucleotide sequence. These results support the idea that the molecular shape of DNA is under selection and can identify evolutionary history.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2749491/" 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/PMC2749491/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, Stephen C J -- Hansen, Loren -- Abaan, Hatice Ozel -- Tullius, Thomas D -- Margulies, Elliott H -- R01 HG003541/HG/NHGRI NIH HHS/ -- R01 HG003541-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):389-92. doi: 10.1126/science.1169050.

    Description: Understanding of plant-pathogen coevolution in natural systems continues to develop as new theories at the population and species level are increasingly informed by studies unraveling the molecular basis of interactions between individual plants and their pathogens. The next challenge lies in further integration of these approaches to develop a comprehensive picture of how life history traits of both players interact with the environment to shape evolutionary trajectories.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2689373/" 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/PMC2689373/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burdon, Jeremy J -- Thrall, Peter H -- R01 GM074265-01A2/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):755-6. doi: 10.1126/science.1171663.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Commonwealth Scientific and Industrial Research Organization (CSIRO)-Plant Industry, Post Office Box 1600, Canberra, ACT 2601, Australia.

    Description: Hepatitis delta virus (HDV) and cytoplasmic polyadenylation element-binding protein 3 (CPEB3) ribozymes form a family of self-cleaving RNAs characterized by a conserved nested double-pseudoknot and minimal sequence conservation. Secondary structure-based searches were used to identify sequences capable of forming this fold, and their self-cleavage activity was confirmed in vitro. Active sequences were uncovered in several marine organisms, two nematodes, an arthropod, a bacterium, and an insect virus, often in multiple sequence families and copies. Sequence searches based on identified ribozymes showed that plants, fungi, and a unicellular eukaryote also harbor the ribozymes. In Anopheles gambiae, the ribozymes were found differentially expressed and self-cleaved at basic developmental stages. Our results indicate that HDV-like ribozymes are abundant in nature and suggest that self-cleaving RNAs may play a variety of biological roles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3159031/" 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/PMC3159031/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Webb, Chiu-Ho T -- Riccitelli, Nathan J -- Ruminski, Dana J -- Luptak, Andrej -- R01 GM094929/GM/NIGMS NIH HHS/ -- R01 GM094929-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):953. doi: 10.1126/science.1178084.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Biochemistry, University of California, Irvine, CA 92697 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965505" target="_blank"〉PubMed〈/a〉

    Description: Despite tremendous progress in understanding the nature of the immune system, the full diversity of an organism's antibody repertoire is unknown. We used high-throughput sequencing of the variable domain of the antibody heavy chain from 14 zebrafish to analyze VDJ usage and antibody sequence. Zebrafish were found to use between 50 and 86% of all possible VDJ combinations and shared a similar frequency distribution, with some correlation of VDJ patterns between individuals. Zebrafish antibodies retained a few thousand unique heavy chains that also exhibited a shared frequency distribution. We found evidence of convergence, in which different individuals made the same antibody. This approach provides insight into the breadth of the expressed antibody repertoire and immunological diversity at the level of an individual organism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3086368/" 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/PMC3086368/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, Joshua A -- Jiang, Ning -- White, Richard A 3rd -- Fisher, Daniel S -- Quake, Stephen R -- DP1 OD000251/OD/NIH HHS/ -- DP1 OD000251-04/OD/NIH HHS/ -- DP1 OD000251-05/OD/NIH HHS/ -- DP1 OD000251-06/OD/NIH HHS/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):807-10. doi: 10.1126/science.1170020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biophysics Program, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423829" target="_blank"〉PubMed〈/a〉

    Description: Plants have distinct RNA polymerase complexes (Pol IV and Pol V) with largely unknown roles in maintaining small RNA-associated gene silencing. Curiously, the eudicot Arabidopsis thaliana is not affected when either function is lost. By use of mutation selection and positional cloning, we showed that the largest subunit of the presumed maize Pol IV is involved in paramutation, an inherited epigenetic change facilitated by an interaction between two alleles, as well as normal maize development. Bioinformatics analyses and nuclear run-on transcription assays indicate that Pol IV does not engage in the efficient RNA synthesis typical of the three major eukaryotic DNA-dependent RNA polymerases. These results indicate that Pol IV employs abnormal RNA polymerase activities to achieve genome-wide silencing and that its absence affects both maize development and heritable epigenetic changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erhard, Karl F Jr -- Stonaker, Jennifer L -- Parkinson, Susan E -- Lim, Jana P -- Hale, Christopher J -- Hollick, Jay B -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1201-5. doi: 10.1126/science.1164508.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant and Microbial Biology, 111 Koshland Hall, University of California, Berkeley, CA 94720-3102, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251626" target="_blank"〉PubMed〈/a〉

    Description: Genes are not simply turned on or off, but instead their expression is fine-tuned to meet the needs of a cell. How genes are modulated so precisely is not well understood. The glucocorticoid receptor (GR) regulates target genes by associating with specific DNA binding sites, the sequences of which differ between genes. Traditionally, these binding sites have been viewed only as docking sites. Using structural, biochemical, and cell-based assays, we show that GR binding sequences, differing by as little as a single base pair, differentially affect GR conformation and regulatory activity. We therefore propose that DNA is a sequence-specific allosteric ligand of GR that tailors the activity of the receptor toward specific target genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2777810/" 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/PMC2777810/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meijsing, Sebastiaan H -- Pufall, Miles A -- So, Alex Y -- Bates, Darren L -- Chen, Lin -- Yamamoto, Keith R -- GM08537/GM/NIGMS NIH HHS/ -- R01 CA020535/CA/NCI NIH HHS/ -- R01 CA020535-31/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):407-10. doi: 10.1126/science.1164265.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372434" target="_blank"〉PubMed〈/a〉

    Description: Primordial organisms of the putative RNA world would have required polymerase ribozymes able to replicate RNA. Known ribozymes with polymerase activity best approximating that needed for RNA replication contain at their catalytic core the class I RNA ligase, an artificial ribozyme with a catalytic rate among the fastest of known ribozymes. Here we present the 3.0 angstrom crystal structure of this ligase. The architecture resembles a tripod, its three legs converging near the ligation junction. Interacting with this tripod scaffold through a series of 10 minor-groove interactions (including two A-minor triads) is the unpaired segment that contributes to and organizes the active site. A cytosine nucleobase and two backbone phosphates abut the ligation junction; their location suggests a model for catalysis resembling that of proteinaceous polymerases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3978776/" 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/PMC3978776/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shechner, David M -- Grant, Robert A -- Bagby, Sarah C -- Koldobskaya, Yelena -- Piccirilli, Joseph A -- Bartel, David P -- GM61835/GM/NIGMS NIH HHS/ -- R01 GM061835/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1271-5. doi: 10.1126/science.1174676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research and Howard Hughes Medical Institute, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965478" target="_blank"〉PubMed〈/a〉

    Description: Sequence preferences of DNA binding proteins are a primary mechanism by which cells interpret the genome. Despite the central importance of these proteins in physiology, development, and evolution, comprehensive DNA binding specificities have been determined experimentally for only a few proteins. Here, we used microarrays containing all 10-base pair sequences to examine the binding specificities of 104 distinct mouse DNA binding proteins representing 22 structural classes. Our results reveal a complex landscape of binding, with virtually every protein analyzed possessing unique preferences. Roughly half of the proteins each recognized multiple distinctly different sequence motifs, challenging our molecular understanding of how proteins interact with their DNA binding sites. This complexity in DNA recognition may be important in gene regulation and in the evolution of transcriptional regulatory networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905877/" 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/PMC2905877/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Badis, Gwenael -- Berger, Michael F -- Philippakis, Anthony A -- Talukder, Shaheynoor -- Gehrke, Andrew R -- Jaeger, Savina A -- Chan, Esther T -- Metzler, Genita -- Vedenko, Anastasia -- Chen, Xiaoyu -- Kuznetsov, Hanna -- Wang, Chi-Fong -- Coburn, David -- Newburger, Daniel E -- Morris, Quaid -- Hughes, Timothy R -- Bulyk, Martha L -- R01 HG003985/HG/NHGRI NIH HHS/ -- R01 HG003985-01/HG/NHGRI NIH HHS/ -- R01 HG003985-02/HG/NHGRI NIH HHS/ -- R01 HG003985-03/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1720-3. doi: 10.1126/science.1162327.

    Description: Hominid fossils predating the emergence of Australopithecus have been sparse and fragmentary. The evolution of our lineage after the last common ancestor we shared with chimpanzees has therefore remained unclear. Ardipithecus ramidus, recovered in ecologically and temporally resolved contexts in Ethiopia's Afar Rift, now illuminates earlier hominid paleobiology and aspects of extant African ape evolution. More than 110 specimens recovered from 4.4-million-year-old sediments include a partial skeleton with much of the skull, hands, feet, limbs, and pelvis. This hominid combined arboreal palmigrade clambering and careful climbing with a form of terrestrial bipedality more primitive than that of Australopithecus. Ar. ramidus had a reduced canine/premolar complex and a little-derived cranial morphology and consumed a predominantly C3 plant-based diet (plants using the C3 photosynthetic pathway). Its ecological habitat appears to have been largely woodland-focused. Ar. ramidus lacks any characters typical of suspension, vertical climbing, or knuckle-walking. Ar. ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor we last shared probably differed substantially from any extant African ape. Hominids and extant African apes have each become highly specialized through very different evolutionary pathways. This evidence also illuminates the origins of orthogrady, bipedality, ecology, diet, and social behavior in earliest Hominidae and helps to define the basal hominid adaptation, thereby accentuating the derived nature of Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, Tim D -- Asfaw, Berhane -- Beyene, Yonas -- Haile-Selassie, Yohannes -- Lovejoy, C Owen -- Suwa, Gen -- WoldeGabriel, Giday -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):75-86.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Evolution Research Center and Department of Integrative Biology, 3101 Valley Life Sciences Building, University of California, Berkeley, CA 94720, USA. timwhite@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810190" target="_blank"〉PubMed〈/a〉

    Description: Miniature inverted repeat transposable elements (MITEs) are widespread in eukaryotic genomes, where they can attain high copy numbers despite a lack of coding capacity. However, little is known about how they originate and amplify. We performed a genome-wide screen of functional interactions between Stowaway MITEs and potential transposases in the rice genome and identified a transpositionally active MITE that possesses key properties that enhance transposition. Although not directly related to its autonomous element, the MITE has less affinity for the transposase than does the autonomous element but lacks a motif repressing transposition in the autonomous element. The MITE contains internal sequences that enhance transposition. These findings suggest that MITEs achieve high transposition activity by scavenging transposases encoded by distantly related and self-restrained autonomous elements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Guojun -- Nagel, Dawn Holligan -- Feschotte, Cedric -- Hancock, C Nathan -- Wessler, Susan R -- New York, N.Y. -- Science. 2009 Sep 11;325(5946):1391-4. doi: 10.1126/science.1175688.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of Georgia, Athens, GA 30602, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19745152" target="_blank"〉PubMed〈/a〉

    Description: To explore the mechanisms and evolution of cell-cycle control, we analyzed the position and conservation of large numbers of phosphorylation sites for the cyclin-dependent kinase Cdk1 in the budding yeast Saccharomyces cerevisiae. We combined specific chemical inhibition of Cdk1 with quantitative mass spectrometry to identify the positions of 547 phosphorylation sites on 308 Cdk1 substrates in vivo. Comparisons of these substrates with orthologs throughout the ascomycete lineage revealed that the position of most phosphorylation sites is not conserved in evolution; instead, clusters of sites shift position in rapidly evolving disordered regions. We propose that the regulation of protein function by phosphorylation often depends on simple nonspecific mechanisms that disrupt or enhance protein-protein interactions. The gain or loss of phosphorylation sites in rapidly evolving regions could facilitate the evolution of kinase-signaling circuits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2813701/" 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/PMC2813701/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holt, Liam J -- Tuch, Brian B -- Villen, Judit -- Johnson, Alexander D -- Gygi, Steven P -- Morgan, David O -- GM037049/GM/NIGMS NIH HHS/ -- GM50684/GM/NIGMS NIH HHS/ -- HG3456/HG/NHGRI NIH HHS/ -- R01 GM069901/GM/NIGMS NIH HHS/ -- R01 GM069901-06/GM/NIGMS NIH HHS/ -- R01 HG003456/HG/NHGRI NIH HHS/ -- R01 HG003456-06/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1682-6. doi: 10.1126/science.1172867.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Physiology and Biochemistry and Biophysics, University of California, San Francisco, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19779198" target="_blank"〉PubMed〈/a〉

    Description: Although the nematode Caenorhabditis elegans produces self-fertile hermaphrodites, it descended from a male/female species, so hermaphroditism provides a model for the origin of novel traits. In the related species C. remanei, which has only male and female sexes, lowering the activity of tra-2 by RNA interference created XX animals that made spermatids as well as oocytes, but their spermatids could not activate without the addition of male seminal fluid. However, by lowering the expression of both tra-2 and swm-1, a gene that regulates sperm activation in C. elegans, we produced XX animals with active sperm that were self-fertile. Thus, the evolution of hermaphroditism in Caenorhabditis probably required two steps: a mutation in the sex-determination pathway that caused XX spermatogenesis and a mutation that allowed these spermatids to self-activate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldi, Chris -- Cho, Soochin -- Ellis, Ronald E -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1002-5. doi: 10.1126/science.1176013.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biomedical Sciences, University of Medicine and Dentistry of New Jersey, Stratford, NJ 08084, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965511" target="_blank"〉PubMed〈/a〉

    Description: The evolution of cis regulatory elements (enhancers) of developmentally regulated genes plays a large role in the evolution of animal morphology. However, the mutational path of enhancer evolution--the number, origin, effect, and order of mutations that alter enhancer function--has not been elucidated. Here, we localized a suite of substitutions in a modular enhancer of the ebony locus responsible for adaptive melanism in a Ugandan Drosophila population. We show that at least five mutations with varied effects arose recently from a combination of standing variation and new mutations and combined to create an allele of large phenotypic effect. We underscore how enhancers are distinct macromolecular entities, subject to fundamentally different, and generally more relaxed, functional constraints relative to protein sequences.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3363996/" 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/PMC3363996/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rebeiz, Mark -- Pool, John E -- Kassner, Victoria A -- Aquadro, Charles F -- Carroll, Sean B -- F32GM78972/GM/NIGMS NIH HHS/ -- F32HG004182/HG/NHGRI NIH HHS/ -- GM036431/GM/NIGMS NIH HHS/ -- R01 GM036431/GM/NIGMS NIH HHS/ -- R01 GM036431-22/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1663-7. doi: 10.1126/science.1178357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Laboratory of Molecular Biology, University of Wisconsin, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20019281" target="_blank"〉PubMed〈/a〉

    Description: Colonization of the land by plants most likely occurred in a stepwise fashion starting in the Mid-Ordovician. The earliest flora of bryophyte-like plants appears to have been cosmopolitan and dominated the planet, relatively unchanged, for some 30 million years. It is represented by fossilized dispersed cryptospores and fragmentary plant remains. In the Early Silurian, cryptospore abundance and diversity diminished abruptly as trilete spores appeared, became abundant, and underwent rapid diversification. This change coincides approximately with the appearance of vascular plant megafossils and probably represents the origin and adaptive radiation of vascular plants. We have obtained a diverse trilete spore occurrence from the Late Ordovician that suggests that vascular plants originated and diversified earlier than previously hypothesized, in Gondwana, before migrating elsewhere and secondarily diversifying.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steemans, Philippe -- Herisse, Alain Le -- Melvin, John -- Miller, Merrell A -- Paris, Florentin -- Verniers, Jacques -- Wellman, Charles H -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):353. doi: 10.1126/science.1169659.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Palaeobotany, B-18, University of Liege, 4000 Liege, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372423" target="_blank"〉PubMed〈/a〉

    Description: Evolution may be dominated by biotic factors, as in the Red Queen model, or abiotic factors, as in the Court Jester model, or a mixture of both. The two models appear to operate predominantly over different geographic and temporal scales: Competition, predation, and other biotic factors shape ecosystems locally and over short time spans, but extrinsic factors such as climate and oceanographic and tectonic events shape larger-scale patterns regionally and globally, and through thousands and millions of years. Paleobiological studies suggest that species diversity is driven largely by abiotic factors such as climate, landscape, or food supply, and comparative phylogenetic approaches offer new insights into clade dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benton, Michael J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):728-32. doi: 10.1126/science.1157719.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK. mike.benton@bristol.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197051" target="_blank"〉PubMed〈/a〉

    Description: Ever since the integration of Mendelian genetics into evolutionary biology in the early 20th century, evolutionary geneticists have for the most part treated genes and mutations as generic entities. However, recent observations indicate that all genes are not equal in the eyes of evolution. Evolutionarily relevant mutations tend to accumulate in hotspot genes and at specific positions within genes. Genetic evolution is constrained by gene function, the structure of genetic networks, and population biology. The genetic basis of evolution may be predictable to some extent, and further understanding of this predictability requires incorporation of the specific functions and characteristics of genes into evolutionary theory.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3184636/" 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/PMC3184636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stern, David L -- Orgogozo, Virginie -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):746-51. doi: 10.1126/science.1158997.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Howard Hughes Medical Institute, Princeton University, Princeton, NJ 08544, USA. dstern@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197055" target="_blank"〉PubMed〈/a〉

    Description: Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in ecosystems ranging from tropical to polar and could serve as sentinel organisms for biogeochemical fluxes of modern oceans during climate change. These broadly distributed primary producers belong to an anciently diverged sister clade to land plants. Although Micromonas isolates have high 18S ribosomal RNA gene identity, we found that genomes from two isolates shared only 90% of their predicted genes. Their independent evolutionary paths were emphasized by distinct riboswitch arrangements as well as the discovery of intronic repeat elements in one isolate, and in metagenomic data, but not in other genomes. Divergence appears to have been facilitated by selection and acquisition processes that actively shape the repertoire of genes that are mutually exclusive between the two isolates differently than the core genes. Analyses of the Micromonas genomes offer valuable insights into ecological differentiation and the dynamic nature of early plant evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worden, Alexandra Z -- Lee, Jae-Hyeok -- Mock, Thomas -- Rouze, Pierre -- Simmons, Melinda P -- Aerts, Andrea L -- Allen, Andrew E -- Cuvelier, Marie L -- Derelle, Evelyne -- Everett, Meredith V -- Foulon, Elodie -- Grimwood, Jane -- Gundlach, Heidrun -- Henrissat, Bernard -- Napoli, Carolyn -- McDonald, Sarah M -- Parker, Micaela S -- Rombauts, Stephane -- Salamov, Aasf -- Von Dassow, Peter -- Badger, Jonathan H -- Coutinho, Pedro M -- Demir, Elif -- Dubchak, Inna -- Gentemann, Chelle -- Eikrem, Wenche -- Gready, Jill E -- John, Uwe -- Lanier, William -- Lindquist, Erika A -- Lucas, Susan -- Mayer, Klaus F X -- Moreau, Herve -- Not, Fabrice -- Otillar, Robert -- Panaud, Olivier -- Pangilinan, Jasmyn -- Paulsen, Ian -- Piegu, Benoit -- Poliakov, Aaron -- Robbens, Steven -- Schmutz, Jeremy -- Toulza, Eve -- Wyss, Tania -- Zelensky, Alexander -- Zhou, Kemin -- Armbrust, E Virginia -- Bhattacharya, Debashish -- Goodenough, Ursula W -- Van de Peer, Yves -- Grigoriev, Igor V -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):268-72. doi: 10.1126/science.1167222.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monterey Bay Aquarium Research Institute, Moss Landing, CA 95039 USA. azworden@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359590" target="_blank"〉PubMed〈/a〉

    Description: The head and mouthpart structures of 11 species of Eurasian scorpionflies represent three extinct and closely related families during a 62-million-year interval from the late Middle Jurassic to the late Early Cretaceous. These taxa had elongate, siphonate (tubular) proboscides and fed on ovular secretions of extinct gymnosperms. Five potential ovulate host-plant taxa co-occur with these insects: a seed fern, conifer, ginkgoopsid, pentoxylalean, and gnetalean. The presence of scorpionfly taxa suggests that siphonate proboscides fed on gymnosperm pollination drops and likely engaged in pollination mutualisms with gymnosperms during the mid-Mesozoic, long before the similar and independent coevolution of nectar-feeding flies, moths, and beetles on angiosperms. All three scorpionfly families became extinct during the later Early Cretaceous, coincident with global gymnosperm-to-angiosperm turnover.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2944650/" 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/PMC2944650/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ren, Dong -- Labandeira, Conrad C -- Santiago-Blay, Jorge A -- Rasnitsyn, Alexandr -- Shih, ChungKun -- Bashkuev, Alexei -- Logan, M Amelia V -- Hotton, Carol L -- Dilcher, David -- Z99 LM999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):840-7. doi: 10.1126/science.1178338.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉College of Life Sciences, Capital Normal University, Beijing 100048, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892981" target="_blank"〉PubMed〈/a〉

    Description: Biologists have long been fascinated by the exceptionally high diversity displayed by some evolutionary groups. Adaptive radiation in such clades is not only spectacular, but is also an extremely complex process influenced by a variety of ecological, genetic, and developmental factors and strongly dependent on historical contingencies. Using modeling approaches, we identify 10 general patterns concerning the temporal, spatial, and genetic/morphological properties of adaptive radiation. Some of these are strongly supported by empirical work, whereas for others, empirical support is more tentative. In almost all cases, more data are needed. Future progress in our understanding of adaptive radiation will be most successful if theoretical and empirical approaches are integrated, as has happened in other areas of evolutionary biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gavrilets, Sergey -- Losos, Jonathan B -- GM56693/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):732-7. doi: 10.1126/science.1157966.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, National Institute for Mathematical and Biological Synthesis, University of Tennessee, Knoxville, TN 37996, USA. sergey@tiem.utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197052" target="_blank"〉PubMed〈/a〉

    Description: Environmental perturbations during mass extinctions were likely manifested differently in epicontinental seas than in open-ocean-facing habitats of comparable depth. Here, we present a dissection of origination and extinction in epicontinental seas versus open-ocean-facing coastal regions in the Permian through Cretaceous periods, an interval through which both settings are well represented in the fossil record. Results demonstrate that extinction rates were significantly higher in open-ocean settings than in epicontinental seas during major mass extinctions but not at other times and that origination rates were significantly higher in open-ocean settings for a protracted interval from the Late Jurassic through the Late Cretaceous. These patterns are manifested even when other paleogeographic and environmental variables are held fixed, indicating that epicontinental seas and open-ocean-facing coastlines carry distinct macroevolutionary signatures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Arnold I -- Foote, Michael -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1106-9. doi: 10.1126/science.1180061.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, University of Cincinnati, Post Office Box 210013, Cincinnati, OH 45221, USA. arnold.miller@uc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965428" target="_blank"〉PubMed〈/a〉

    Description: The toolbox of rat genetics currently lacks the ability to introduce site-directed, heritable mutations into the genome to create knockout animals. By using engineered zinc-finger nucleases (ZFNs) designed to target an integrated reporter and two endogenous rat genes, Immunoglobulin M (IgM) and Rab38, we demonstrate that a single injection of DNA or messenger RNA encoding ZFNs into the one-cell rat embryo leads to a high frequency of animals carrying 25 to 100% disruption at the target locus. These mutations are faithfully and efficiently transmitted through the germline. Our data demonstrate the feasibility of targeted gene disruption in multiple rat strains within 4 months time, paving the way to a humanized monoclonal antibody platform and additional human disease models.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2831805/" 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/PMC2831805/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geurts, Aron M -- Cost, Gregory J -- Freyvert, Yevgeniy -- Zeitler, Bryan -- Miller, Jeffrey C -- Choi, Vivian M -- Jenkins, Shirin S -- Wood, Adam -- Cui, Xiaoxia -- Meng, Xiangdong -- Vincent, Anna -- Lam, Stephen -- Michalkiewicz, Mieczyslaw -- Schilling, Rebecca -- Foeckler, Jamie -- Kalloway, Shawn -- Weiler, Hartmut -- Menoret, Severine -- Anegon, Ignacio -- Davis, Gregory D -- Zhang, Lei -- Rebar, Edward J -- Gregory, Philip D -- Urnov, Fyodor D -- Jacob, Howard J -- Buelow, Roland -- 5P01HL082798-03/HL/NHLBI NIH HHS/ -- 5U01HL066579-08/HL/NHLBI NIH HHS/ -- P01 HL082798/HL/NHLBI NIH HHS/ -- P01 HL082798-03/HL/NHLBI NIH HHS/ -- U01 HL066579/HL/NHLBI NIH HHS/ -- U01 HL066579-08/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):433. doi: 10.1126/science.1172447.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human and Molecular Genetics Center, Medical College of Wisconsin, Milwaukee, WI 52336, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19628861" target="_blank"〉PubMed〈/a〉

    Description: Combining biomolecular function with integrated circuit technology could usher in a new era of biologically enabled electronics. A key challenge has been coupling different molecular functions to specific chip locations for communication with the circuit. We used spatially confined electric fields to assemble different populations of DNA-coated nanowires to desired positions with an accuracy that enabled postassembly fabrication of contacts to each individual nanowire, with high yield and without loss of DNA function. This combination of off-chip synthesis and biofunctionalization with high-density, heterogeneous assembly and integration at the individual nanowire level points to new ways of incorporating biological functionality with silicon electronics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2837912/" 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/PMC2837912/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morrow, Thomas J -- Li, Mingwei -- Kim, Jaekyun -- Mayer, Theresa S -- Keating, Christine D -- R01 EB000268/EB/NIBIB NIH HHS/ -- R01 EB000268-08/EB/NIBIB NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):352. doi: 10.1126/science.1165921.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Pennsylvania State University, University Park, PA 16802, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19150837" target="_blank"〉PubMed〈/a〉

    Description: John Nash showed that within a complex system, individuals are best off if they make the best decision that they can, taking into account the decisions of the other individuals. Here, we investigate whether similar principles influence the evolution of signaling networks in multicellular animals. Specifically, by analyzing a set of metazoan species we observed a striking negative correlation of genomically encoded tyrosine content with biological complexity (as measured by the number of cell types in each organism). We discuss how this observed tyrosine loss correlates with the expansion of tyrosine kinases in the evolution of the metazoan lineage and how it may relate to the optimization of signaling systems in multicellular animals. We propose that this phenomenon illustrates genome-wide adaptive evolution to accommodate beneficial genetic perturbation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3066034/" 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/PMC3066034/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tan, Chris Soon Heng -- Pasculescu, Adrian -- Lim, Wendell A -- Pawson, Tony -- Bader, Gary D -- Linding, Rune -- R01 GM055040/GM/NIGMS NIH HHS/ -- R01 GM055040-11/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1686-8. doi: 10.1126/science.1174301.

    Description: The turtle shell offers a fascinating case study of vertebrate evolution, based on the modification of a common body plan. The carapace is formed from ribs, which encapsulate the scapula; this stands in contrast to the typical amniote body plan and serves as a key to understanding turtle evolution. Comparative analyses of musculoskeletal development between the Chinese soft-shelled turtle and other amniotes revealed that initial turtle development conforms to the amniote pattern; however, during embryogenesis, lateral rib growth results in a shift of elements. In addition, some limb muscles establish new turtle-specific attachments associated with carapace formation. We propose that the evolutionary origin of the turtle body plan results from heterotopy based on folding and novel connectivities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nagashima, Hiroshi -- Sugahara, Fumiaki -- Takechi, Masaki -- Ericsson, Rolf -- Kawashima-Ohya, Yoshie -- Narita, Yuichi -- Kuratani, Shigeru -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):193-6. doi: 10.1126/science.1173826.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Evolutionary Morphology, RIKEN Center for Developmental Biology, 2-2-3 Minatojima-minami, Kobe 650-0047, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590000" target="_blank"〉PubMed〈/a〉

Over 32,000 genes were predicted, of which 99.8% were placed on reference chromosomes. Nearly 85% of the genome is composed of hundreds of families of transposable elements, dispersed nonuniformly across the genome. These were responsible for the capture and amplification of numerous gene fragments and affect the composition, sizes, and positions of centromeres. We also report on the correlation of methylation-poor regions with Mu transposon insertions and recombination, and copy number variants with insertions and/or deletions, as well as how uneven gene losses between duplicated regions were involved in returning an ancient allotetraploid to a genetically diploid state. These analyses inform and set the stage for further investigations to improve our understanding of the domestication and agricultural improvements of maize.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schnable, Patrick S -- Ware, Doreen -- Fulton, Robert S -- Stein, Joshua C -- Wei, Fusheng -- Pasternak, Shiran -- Liang, Chengzhi -- Zhang, Jianwei -- Fulton, Lucinda -- Graves, Tina A -- Minx, Patrick -- Reily, Amy Denise -- Courtney, Laura -- Kruchowski, Scott S -- Tomlinson, Chad -- Strong, Cindy -- Delehaunty, Kim -- Fronick, Catrina -- Courtney, Bill -- Rock, Susan M -- Belter, Eddie -- Du, Feiyu -- Kim, Kyung -- Abbott, Rachel M -- Cotton, Marc -- Levy, Andy -- Marchetto, Pamela -- Ochoa, Kerri -- Jackson, Stephanie M -- Gillam, Barbara -- Chen, Weizu -- Yan, Le -- Higginbotham, Jamey -- Cardenas, Marco -- Waligorski, Jason -- Applebaum, Elizabeth -- Phelps, Lindsey -- Falcone, Jason -- Kanchi, Krishna -- Thane, Thynn -- Scimone, Adam -- Thane, Nay -- Henke, Jessica -- Wang, Tom -- Ruppert, Jessica -- Shah, Neha -- Rotter, Kelsi -- Hodges, Jennifer -- Ingenthron, Elizabeth -- Cordes, Matt -- Kohlberg, Sara -- Sgro, Jennifer -- Delgado, Brandon -- Mead, Kelly -- Chinwalla, Asif -- Leonard, Shawn -- Crouse, Kevin -- Collura, Kristi -- Kudrna, Dave -- Currie, Jennifer -- He, Ruifeng -- Angelova, Angelina -- Rajasekar, Shanmugam -- Mueller, Teri -- Lomeli, Rene -- Scara, Gabriel -- Ko, Ara -- Delaney, Krista -- Wissotski, Marina -- Lopez, Georgina -- Campos, David -- Braidotti, Michele -- Ashley, Elizabeth -- Golser, Wolfgang -- Kim, HyeRan -- Lee, Seunghee -- Lin, Jinke -- Dujmic, Zeljko -- Kim, Woojin -- Talag, Jayson -- Zuccolo, Andrea -- Fan, Chuanzhu -- Sebastian, Aswathy -- Kramer, Melissa -- Spiegel, Lori -- Nascimento, Lidia -- Zutavern, Theresa -- Miller, Beth -- Ambroise, Claude -- Muller, Stephanie -- Spooner, Will -- Narechania, Apurva -- Ren, Liya -- Wei, Sharon -- Kumari, Sunita -- Faga, Ben -- Levy, Michael J -- McMahan, Linda -- Van Buren, Peter -- Vaughn, Matthew W -- Ying, Kai -- Yeh, Cheng-Ting -- Emrich, Scott J -- Jia, Yi -- Kalyanaraman, Ananth -- Hsia, An-Ping -- Barbazuk, W Brad -- Baucom, Regina S -- Brutnell, Thomas P -- Carpita, Nicholas C -- Chaparro, Cristian -- Chia, Jer-Ming -- Deragon, Jean-Marc -- Estill, James C -- Fu, Yan -- Jeddeloh, Jeffrey A -- Han, Yujun -- Lee, Hyeran -- Li, Pinghua -- Lisch, Damon R -- Liu, Sanzhen -- Liu, Zhijie -- Nagel, Dawn Holligan -- McCann, Maureen C -- SanMiguel, Phillip -- Myers, Alan M -- Nettleton, Dan -- Nguyen, John -- Penning, Bryan W -- Ponnala, Lalit -- Schneider, Kevin L -- Schwartz, David C -- Sharma, Anupma -- Soderlund, Carol -- Springer, Nathan M -- Sun, Qi -- Wang, Hao -- Waterman, Michael -- Westerman, Richard -- Wolfgruber, Thomas K -- Yang, Lixing -- Yu, Yeisoo -- Zhang, Lifang -- Zhou, Shiguo -- Zhu, Qihui -- Bennetzen, Jeffrey L -- Dawe, R Kelly -- Jiang, Jiming -- Jiang, Ning -- Presting, Gernot G -- Wessler, Susan R -- Aluru, Srinivas -- Martienssen, Robert A -- Clifton, Sandra W -- McCombie, W Richard -- Wing, Rod A -- Wilson, Richard K -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1112-5. doi: 10.1126/science.1178534.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Plant Genomics, Iowa State University, Ames, IA 50011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965430" target="_blank"〉PubMed〈/a〉

    Description: Male animals of many species deploy conditional reproductive strategies that contain distinct alternative phenotypes. Such facultatively expressed male tactics are assumed to be due to a single developmental threshold mechanism switching between the expression of two alternative phenotypes. However, we discovered a clade of dung beetles that commonly expresses two threshold mechanisms, resulting in three alternative phenotypes (male trimorphism). Once recognized, we found trimorphism in other beetle families that involves different types of male weapons. Evidence that insects assumed to be dimorphic can express three facultative male forms suggests that we need to adjust how we think about animal mating systems and the evolution of conditional strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowland, J Mark -- Emlen, Douglas J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):773-6. doi: 10.1126/science.1167345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of New Mexico, Albuquerque, NM 87131, USA. rowland@unm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197062" target="_blank"〉PubMed〈/a〉

    Description: Several classes of nucleic acid analogs have been reported, but no synthetic informational polymer has yet proven responsive to selection pressures under enzyme-free conditions. Here, we introduce an oligomer family that efficiently self-assembles by means of reversible covalent anchoring of nucleobase recognition units onto simple oligo-dipeptide backbones [thioester peptide nucleic acids (tPNAs)] and undergoes dynamic sequence modification in response to changing templates in solution. The oligomers specifically self-pair with complementary tPNA strands and cross-pair with RNA and DNA in Watson-Crick fashion. Thus, tPNA combines base-pairing interactions with the side-chain functionalities of typical peptides and proteins. These characteristics might prove advantageous for the design or selection of catalytic constructs or biomaterials that are capable of dynamic sequence repair and adaptation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ura, Yasuyuki -- Beierle, John M -- Leman, Luke J -- Orgel, Leslie E -- Ghadiri, M Reza -- New York, N.Y. -- Science. 2009 Jul 3;325(5936):73-7. doi: 10.1126/science.1174577.

    Description: The femur and pelvis of Ardipithecus ramidus have characters indicative of both upright bipedal walking and movement in trees. Consequently, bipedality in Ar. ramidus was more primitive than in later Australopithecus. Compared with monkeys and Early Miocene apes such as Proconsul, the ilium in Ar. ramidus is mediolaterally expanded, and its sacroiliac joint is located more posteriorly. These changes are shared with some Middle and Late Miocene apes as well as with African apes and later hominids. However, in contrast to extant apes, bipedality in Ar. ramidus was facilitated by craniocaudal shortening of the ilium and enhanced lordotic recurvature of the lower spine. Given the predominant absence of derived traits in other skeletal regions of Ar. ramidus, including the forelimb, these adaptations were probably acquired shortly after divergence from our last common ancestor with chimpanzees. They therefore bear little or no functional relationship to the highly derived suspension, vertical climbing, knuckle-walking, and facultative bipedality of extant African apes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lovejoy, C Owen -- Suwa, Gen -- Spurlock, Linda -- Asfaw, Berhane -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):71e1-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, School of Biomedical Sciences, Kent State University, Kent, OH 44242-0001, USA. olovejoy@aol.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810197" target="_blank"〉PubMed〈/a〉

    Description: In vertebrates, the readily apparent left/right (L/R) anatomical asymmetries of the internal organs can be traced to molecular events initiated at or near the time of gastrulation. However, the earliest steps of this process do not seem to be universally conserved. In particular, how this axis is first defined in chicks has remained problematic. Here we show that asymmetric cell rearrangements take place within chick embryos, creating a leftward movement of cells around the node. It is the relative displacement of cells expressing sonic hedgehog (Shh) and fibroblast growth factor 8 (Fgf8) that is responsible for establishing their asymmetric expression patterns. The creation of asymmetric expression domains as a passive effect of cell movements represents an alternative strategy for breaking L/R symmetry in gene activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2993078/" 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/PMC2993078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gros, Jerome -- Feistel, Kerstin -- Viebahn, Christoph -- Blum, Martin -- Tabin, Clifford J -- R01 HD045499/HD/NICHD NIH HHS/ -- R01 HD045499-06/HD/NICHD NIH HHS/ -- R01-HD045499/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2009 May 15;324(5929):941-4. doi: 10.1126/science.1172478.

    Description: As the largest predators of the Cambrian seas, the anomalocaridids had an important impact in structuring the first complex marine animal communities, but many aspects of anomalocaridid morphology, diversity, ecology, and affinity remain unclear owing to a paucity of specimens. Here we describe the anomalocaridid Hurdia, based on several hundred specimens from the Burgess Shale in Canada. Hurdia possesses a general body architecture similar to those of Anomalocaris and Laggania, including the presence of exceptionally well-preserved gills, but differs from those anomalocaridids by possessing a prominent anterior carapace structure. These features amplify and clarify the diversity of known anomalocaridid morphology and provide insight into the origins of important arthropod features, such as the head shield and respiratory exites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Daley, Allison C -- Budd, Graham E -- Caron, Jean-Bernard -- Edgecombe, Gregory D -- Collins, Desmond -- New York, N.Y. -- Science. 2009 Mar 20;323(5921):1597-600. doi: 10.1126/science.1169514.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Palaeobiology, Uppsala University, Villavagen 16, Uppsala SE-752 36, Sweden. allison.daley@geo.uu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19299617" target="_blank"〉PubMed〈/a〉

    Description: To study basic principles of transcriptome organization in bacteria, we analyzed one of the smallest self-replicating organisms, Mycoplasma pneumoniae. We combined strand-specific tiling arrays, complemented by transcriptome sequencing, with more than 252 spotted arrays. We detected 117 previously undescribed, mostly noncoding transcripts, 89 of them in antisense configuration to known genes. We identified 341 operons, of which 139 are polycistronic; almost half of the latter show decaying expression in a staircase-like manner. Under various conditions, operons could be divided into 447 smaller transcriptional units, resulting in many alternative transcripts. Frequent antisense transcripts, alternative transcripts, and multiple regulators per gene imply a highly dynamic transcriptome, more similar to that of eukaryotes than previously thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guell, Marc -- van Noort, Vera -- Yus, Eva -- Chen, Wei-Hua -- Leigh-Bell, Justine -- Michalodimitrakis, Konstantinos -- Yamada, Takuji -- Arumugam, Manimozhiyan -- Doerks, Tobias -- Kuhner, Sebastian -- Rode, Michaela -- Suyama, Mikita -- Schmidt, Sabine -- Gavin, Anne-Claude -- Bork, Peer -- Serrano, Luis -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1268-71. doi: 10.1126/science.1176951.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Genomic Regulation (CRG), Universitat Pompeu Fabra, Barcelona, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965477" target="_blank"〉PubMed〈/a〉

    Description: Selenocysteine is the only genetically encoded amino acid in humans whose biosynthesis occurs on its cognate transfer RNA (tRNA). O-Phosphoseryl-tRNA:selenocysteinyl-tRNA synthase (SepSecS) catalyzes the final step of selenocysteine formation by a poorly understood tRNA-dependent mechanism. The crystal structure of human tRNA(Sec) in complex with SepSecS, phosphoserine, and thiophosphate, together with in vivo and in vitro enzyme assays, supports a pyridoxal phosphate-dependent mechanism of Sec-tRNA(Sec) formation. Two tRNA(Sec) molecules, with a fold distinct from other canonical tRNAs, bind to each SepSecS tetramer through their 13-base pair acceptor-TPsiC arm (where Psi indicates pseudouridine). The tRNA binding is likely to induce a conformational change in the enzyme's active site that allows a phosphoserine covalently attached to tRNA(Sec), but not free phosphoserine, to be oriented properly for the reaction to occur.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2857584/" 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/PMC2857584/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Palioura, Sotiria -- Sherrer, R Lynn -- Steitz, Thomas A -- Soll, Dieter -- Simonovic, Miljan -- R01 GM022854/GM/NIGMS NIH HHS/ -- R01 GM022854-33/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Jul 17;325(5938):321-5. doi: 10.1126/science.1173755.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biophysics and Biochemistry, Yale University, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19608919" target="_blank"〉PubMed〈/a〉

    Description: The molecular mechanisms underlying major phenotypic changes that have evolved repeatedly in nature are generally unknown. Pelvic loss in different natural populations of threespine stickleback fish has occurred through regulatory mutations deleting a tissue-specific enhancer of the Pituitary homeobox transcription factor 1 (Pitx1) gene. The high prevalence of deletion mutations at Pitx1 may be influenced by inherent structural features of the locus. Although Pitx1 null mutations are lethal in laboratory animals, Pitx1 regulatory mutations show molecular signatures of positive selection in pelvic-reduced populations. These studies illustrate how major expression and morphological changes can arise from single mutational leaps in natural populations, producing new adaptive alleles via recurrent regulatory alterations in a key developmental control gene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3109066/" 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/PMC3109066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, Yingguang Frank -- Marks, Melissa E -- Jones, Felicity C -- Villarreal, Guadalupe Jr -- Shapiro, Michael D -- Brady, Shannon D -- Southwick, Audrey M -- Absher, Devin M -- Grimwood, Jane -- Schmutz, Jeremy -- Myers, Richard M -- Petrov, Dmitri -- Jonsson, Bjarni -- Schluter, Dolph -- Bell, Michael A -- Kingsley, David M -- P50 HG002568/HG/NHGRI NIH HHS/ -- P50 HG002568-09/HG/NHGRI NIH HHS/ -- P50 HG02568/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):302-5. doi: 10.1126/science.1182213.

    Description: Pathogens can use DNA recombination to promote antigenic variation (Av) of surface structures to avoid immune detection. We identified a cis-acting DNA sequence near the antigenically variable pilin locus of the human pathogen, Neisseria gonorrhoeae. This 16-base pair guanine (G)-rich sequence was required for pilin Av and formed a guanine quartet (G4) structure in vitro. Individual mutations that disrupted the structure also blocked pilin Av and prevented nicks required for recombination from occurring within the G4 region. A compound that binds and stabilizes G4 structures also inhibited pilin Av and prevented nicks from occurring on the G-rich strand. This site constitutes a recombination initiation sequence/structure that directs gene conversion to a specific chromosomal locus.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803317/" 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/PMC2803317/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cahoon, Laty A -- Seifert, H Steven -- R01 AI044239/AI/NIAID NIH HHS/ -- R01 AI044239-08/AI/NIAID NIH HHS/ -- R01 AI044239-09/AI/NIAID NIH HHS/ -- R01 AI044239-10/AI/NIAID NIH HHS/ -- R01 AI055977/AI/NIAID NIH HHS/ -- R01 AI055977-03/AI/NIAID NIH HHS/ -- R01 AI055977-04/AI/NIAID NIH HHS/ -- R01 AI055977-05/AI/NIAID NIH HHS/ -- R01AI044239/AI/NIAID NIH HHS/ -- R01AI055977/AI/NIAID NIH HHS/ -- R37 AI033493/AI/NIAID NIH HHS/ -- R37 AI033493-14/AI/NIAID NIH HHS/ -- R37 AI033493-15/AI/NIAID NIH HHS/ -- R37 AI033493-16/AI/NIAID NIH HHS/ -- R37AI033493/AI/NIAID NIH HHS/ -- T32GM08061/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 7;325(5941):764-7. doi: 10.1126/science.1175653.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Northwestern University Feinberg School of Medicine, 303 East Chicago Avenue, Chicago, IL 60611, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19661435" target="_blank"〉PubMed〈/a〉

    Description: Infection by human rhinovirus (HRV) is a major cause of upper and lower respiratory tract disease worldwide and displays considerable phenotypic variation. We examined diversity by completing the genome sequences for all known serotypes (n = 99). Superimposition of capsid crystal structure and optimal-energy RNA configurations established alignments and phylogeny. These revealed conserved motifs; clade-specific diversity, including a potential newly identified species (HRV-D); mutations in field isolates; and recombination. In analogy with poliovirus, a hypervariable 5' untranslated region tract may affect virulence. A configuration consistent with nonscanning internal ribosome entry was found in all HRVs and may account for rapid translation. The data density from complete sequences of the reference HRVs provided high resolution for this degree of modeling and serves as a platform for full genome-based epidemiologic studies and antiviral or vaccine development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3923423/" 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/PMC3923423/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Palmenberg, Ann C -- Spiro, David -- Kuzmickas, Ryan -- Wang, Shiliang -- Djikeng, Appolinaire -- Rathe, Jennifer A -- Fraser-Liggett, Claire M -- Liggett, Stephen B -- R01 HL091490/HL/NHLBI NIH HHS/ -- U19 AI070503/AI/NIAID NIH HHS/ -- U19-AI070503/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):55-9. doi: 10.1126/science.1165557.

    Description: Morphological diversity within closely related species is an essential aspect of evolution and adaptation. Mutations in the Melanocortin 1 receptor (Mc1r) gene contribute to pigmentary diversity in natural populations of fish, birds, and many mammals. However, melanism in the gray wolf, Canis lupus, is caused by a different melanocortin pathway component, the K locus, that encodes a beta-defensin protein that acts as an alternative ligand for Mc1r. We show that the melanistic K locus mutation in North American wolves derives from past hybridization with domestic dogs, has risen to high frequency in forested habitats, and exhibits a molecular signature of positive selection. The same mutation also causes melanism in the coyote, Canis latrans, and in Italian gray wolves, and hence our results demonstrate how traits selected in domesticated species can influence the morphological diversity of their wild relatives.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2903542/" 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/PMC2903542/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Tovi M -- vonHoldt, Bridgett M -- Candille, Sophie I -- Musiani, Marco -- Greco, Claudia -- Stahler, Daniel R -- Smith, Douglas W -- Padhukasahasram, Badri -- Randi, Ettore -- Leonard, Jennifer A -- Bustamante, Carlos D -- Ostrander, Elaine A -- Tang, Hua -- Wayne, Robert K -- Barsh, Gregory S -- P01 DK068384/DK/NIDDK NIH HHS/ -- P01 DK068384-050001/DK/NIDDK NIH HHS/ -- R01 GM068882/GM/NIGMS NIH HHS/ -- R01 GM068882-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1339-43. doi: 10.1126/science.1165448.

    Description: The long-term effects of mass extinctions on spatial and evolutionary dynamics have been poorly studied. Here we show that the evolutionary consequences of the end-Cretaceous [Cretaceous/Paleogene (K/Pg)] mass extinction persist in present-day biogeography. The geologic ages of genera of living marine bivalves show a significant break from a smooth exponential distribution, corresponding to the K/Pg boundary. The break reflects a permanent increase in origination rates, intermediate between the Mesozoic rate and the post-extinction recovery pulse. This global rate shift is most clearly seen today in tropical bioprovinces and weakens toward the poles. Coupled with the modern geographic distributions of taxa originating before and after the K/Pg boundary, this spatial pattern indicates that tropical origination rates after the K/Pg event have left a permanent mark on the taxonomic and biogeographic structure of the modern biota, despite the complex Cenozoic history of marine environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krug, Andrew Z -- Jablonski, David -- Valentine, James W -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):767-71. doi: 10.1126/science.1164905.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197060" target="_blank"〉PubMed〈/a〉

    Description: Classification was a key practice of the natural history sciences in the early 19th century, but leading taxonomists disagreed over basic matters, such as how many species the British flora contained. In this arena, the impact of Charles Darwin's ideas was surprisingly limited. For taxonomists like Darwin's friend, Joseph Dalton Hooker, the priority was to establish a reputation as a philosophical naturalist, and to do so Hooker embarked on a survey of global vegetation patterns. He believed that taxonomic "splitters" hindered his ambition to create natural laws for botany (and hence establish it as a prestigious science) by generating a multitude of redundant synonyms for every plant variety. Despite the fact that Darwin's ideas apparently promised a justification for splitting, they also offered a philosophical justification for Hooker's taxonomic practice, and so he enthusiastically championed his friend.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Endersby, Jim -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1496-9. doi: 10.1126/science.1165915.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of History, University of Sussex, Falmer, Brighton BN1 9SH, UK. j.j.endersby@sussex.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007893" target="_blank"〉PubMed〈/a〉

    Description: To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.〈br /〉〈br /〉〈a

    Description: The definitive mammalian middle ear (DMME) is defined by the loss of embryonic Meckel's cartilage and disconnection of the middle ear from the mandible in adults. It is a major feature distinguishing living mammals from nonmammalian vertebrates. We report a Cretaceous trechnotherian mammal with an ossified Meckel's cartilage in the adult, showing that homoplastic evolution of the DMME occurred in derived therian mammals, besides the known cases of eutriconodonts. The mandible with ossified Meckel's cartilage appears to be paedomorphic. Reabsorption of embryonic Meckel's cartilage to disconnect the ear ossicles from the mandible is patterned by a network of genes and signaling pathways. This fossil suggests that developmental heterochrony and gene patterning are major mechanisms in homplastic evolution of the DMME.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ji, Qiang -- Luo, Zhe-Xi -- Zhang, Xingliao -- Yuan, Chong-Xi -- Xu, Li -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):278-81. doi: 10.1126/science.1178501.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19815774" target="_blank"〉PubMed〈/a〉

    Description: Genetic changes contributing to phenotypic differences within or between species have been identified for a handful of traits, but the relationship between alleles underlying intraspecific polymorphism and interspecific divergence is largely unknown. We found that noncoding changes in the tan gene, as well as changes linked to the ebony gene, contribute to pigmentation divergence between closely related Drosophila species. Moreover, we found that alleles linked to tan and ebony fixed in one Drosophila species also contribute to variation within another species, and that multiple genotypes underlie similar phenotypes even within the same population. These alleles appear to predate speciation, which suggests that standing genetic variation present in the common ancestor gave rise to both intraspecific polymorphism and interspecific divergence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wittkopp, Patricia J -- Stewart, Emma E -- Arnold, Lisa L -- Neidert, Adam H -- Haerum, Belinda K -- Thompson, Elizabeth M -- Akhras, Saleh -- Smith-Winberry, Gabriel -- Shefner, Laura -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):540-4. doi: 10.1126/science.1176980.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA. wittkopp@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19900891" target="_blank"〉PubMed〈/a〉

    Description: TAL effectors of plant pathogenic bacteria in the genus Xanthomonas bind host DNA and activate genes that contribute to disease or turn on defense. Target specificity depends on an effector-variable number of typically 34 amino acid repeats, but the mechanism of recognition is not understood. We show that a repeat-variable pair of residues specifies the nucleotides in the target site, one pair to one nucleotide, with no apparent context dependence. Our finding represents a previously unknown mechanism for protein-DNA recognition that explains TAL effector specificity, enables target site prediction, and opens prospects for use of TAL effectors in research and biotechnology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moscou, Matthew J -- Bogdanove, Adam J -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1501. doi: 10.1126/science.1178817.

    Description: Retroviruses have the potential to acquire host cell-derived genetic material during reverse transcription and can integrate into the genomes of larger, more complex DNA viruses. In contrast, RNA viruses were believed not to integrate into the host's genome under any circumstances. We found that illegitimate recombination between an exogenous nonretroviral RNA virus, lymphocytic choriomeningitis virus, and the endogenous intracisternal A-type particle (IAP) retrotransposon occurred and led to reverse transcription of exogenous viral RNA. The resulting complementary DNA was integrated into the host's genome with an IAP element. Thus, RNA viruses should be closely scrutinized for any capacity to interact with endogenous retroviral elements before their approval for therapeutic use in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geuking, Markus B -- Weber, Jacqueline -- Dewannieux, Marie -- Gorelik, Elieser -- Heidmann, Thierry -- Hengartner, Hans -- Zinkernagel, Rolf M -- Hangartner, Lars -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):393-6. doi: 10.1126/science.1167375.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Experimental Immunology, University Hospital Zurich, Schmelzbergstrasse 12, 8091 Zurich, Switzerland. geuking@mcmaster.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19150848" target="_blank"〉PubMed〈/a〉

    Description: Adenosine-to-inosine (A-to-I) RNA editing leads to transcriptome diversity and is important for normal brain function. To date, only a handful of functional sites have been identified in mammals. We developed an unbiased assay to screen more than 36,000 computationally predicted nonrepetitive A-to-I sites using massively parallel target capture and DNA sequencing. A comprehensive set of several hundred human RNA editing sites was detected by comparing genomic DNA with RNAs from seven tissues of a single individual. Specificity of our profiling was supported by observations of enrichment with known features of targets of adenosine deaminases acting on RNA (ADAR) and validation by means of capillary sequencing. This efficient approach greatly expands the repertoire of RNA editing targets and can be applied to studies involving RNA editing-related human diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Jin Billy -- Levanon, Erez Y -- Yoon, Jung-Ki -- Aach, John -- Xie, Bin -- Leproust, Emily -- Zhang, Kun -- Gao, Yuan -- Church, George M -- New York, N.Y. -- Science. 2009 May 29;324(5931):1210-3. doi: 10.1126/science.1170995.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, 77 Avenue Louis Pasteur, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478186" target="_blank"〉PubMed〈/a〉

    Description: Rates and mechanisms of intron gain and loss have traditionally been inferred from alignments of highly conserved genes sampled from phylogenetically distant taxa. We report a population-genomic approach that detected 24 discordant intron/exon boundaries between the whole-genome sequences of two Daphnia pulex isolates. Sequencing of presence/absence loci across a collection of D. pulex isolates and outgroup Daphnia species shows that most polymorphisms are a consequence of recent gains, with parallel gains often occurring at the same locations in independent allelic lineages. More than half of the recent gains are associated with short sequence repeats, suggesting an origin via repair of staggered double-strand breaks. By comparing the allele-frequency spectrum of intron-gain alleles with that for derived single-base substitutions, we also provide evidence that newly arisen introns are intrinsically deleterious and tend to accumulate in population-genetic settings where random genetic drift is a relatively strong force.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3878872/" 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/PMC3878872/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Wenli -- Tucker, Abraham E -- Sung, Way -- Thomas, W Kelley -- Lynch, Michael -- R01 GM036827/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1260-2. doi: 10.1126/science.1179302.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Indiana University, Bloomington, IN 47405, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965475" target="_blank"〉PubMed〈/a〉

    Description: The highly fragmented and distorted skull of the adult skeleton ARA-VP-6/500 includes most of the dentition and preserves substantial parts of the face, vault, and base. Anatomical comparisons and micro-computed tomography-based analysis of this and other remains reveal pre-Australopithecus hominid craniofacial morphology and structure. The Ardipithecus ramidus skull exhibits a small endocranial capacity (300 to 350 cubic centimeters), small cranial size relative to body size, considerable midfacial projection, and a lack of modern African ape-like extreme lower facial prognathism. Its short posterior cranial base differs from that of both Pan troglodytes and P. paniscus. Ar. ramidus lacks the broad, anteriorly situated zygomaxillary facial skeleton developed in later Australopithecus. This combination of features is apparently shared by Sahelanthropus, showing that the Mio-Pliocene hominid cranium differed substantially from those of both extant apes and Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suwa, Gen -- Asfaw, Berhane -- Kono, Reiko T -- Kubo, Daisuke -- Lovejoy, C Owen -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):68e1-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University Museum, University of Tokyo, Hongo, Bunkyo-ku, Tokyo, 113-0033, Japan. suwa@um.u-tokyo.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810194" target="_blank"〉PubMed〈/a〉

    Description: Strict one-to-one correspondence between codons and amino acids is thought to be an essential feature of the genetic code. However, we report that one codon can code for two different amino acids with the choice of the inserted amino acid determined by a specific 3' untranslated region structure and location of the dual-function codon within the messenger RNA (mRNA). We found that the codon UGA specifies insertion of selenocysteine and cysteine in the ciliate Euplotes crassus, that the dual use of this codon can occur even within the same gene, and that the structural arrangements of Euplotes mRNA preserve location-dependent dual function of UGA when expressed in mammalian cells. Thus, the genetic code supports the use of one codon to code for multiple amino acids.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3088105/" 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/PMC3088105/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turanov, Anton A -- Lobanov, Alexey V -- Fomenko, Dmitri E -- Morrison, Hilary G -- Sogin, Mitchell L -- Klobutcher, Lawrence A -- Hatfield, Dolph L -- Gladyshev, Vadim N -- AI058054/AI/NIAID NIH HHS/ -- GM061603/GM/NIGMS NIH HHS/ -- GM065204/GM/NIGMS NIH HHS/ -- R01 GM061603/GM/NIGMS NIH HHS/ -- R01 GM061603-04S2/GM/NIGMS NIH HHS/ -- ZIA BC010767-03/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 9;323(5911):259-61. doi: 10.1126/science.1164748.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Redox Biology Center, University of Nebraska, Lincoln, NE 68588, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19131629" target="_blank"〉PubMed〈/a〉
