    Phytophthora genome sequences uncover evolutionary origins and mechanisms of pathogenesis (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-02
    Description: Draft genome sequences have been determined for the soybean pathogen Phytophthora sojae and the sudden oak death pathogen Phytophthora ramorum. Oomycetes such as these Phytophthora species share the kingdom Stramenopila with photosynthetic algae such as diatoms, and the presence of many Phytophthora genes of probable phototroph origin supports a photosynthetic ancestry for the stramenopiles. Comparison of the two species' genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oomycete avirulence genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tyler, Brett M -- Tripathy, Sucheta -- Zhang, Xuemin -- Dehal, Paramvir -- Jiang, Rays H Y -- Aerts, Andrea -- Arredondo, Felipe D -- Baxter, Laura -- Bensasson, Douda -- Beynon, Jim L -- Chapman, Jarrod -- Damasceno, Cynthia M B -- Dorrance, Anne E -- Dou, Daolong -- Dickerman, Allan W -- Dubchak, Inna L -- Garbelotto, Matteo -- Gijzen, Mark -- Gordon, Stuart G -- Govers, Francine -- Grunwald, Niklaus J -- Huang, Wayne -- Ivors, Kelly L -- Jones, Richard W -- Kamoun, Sophien -- Krampis, Konstantinos -- Lamour, Kurt H -- Lee, Mi-Kyung -- McDonald, W Hayes -- Medina, Monica -- Meijer, Harold J G -- Nordberg, Eric K -- Maclean, Donald J -- Ospina-Giraldo, Manuel D -- Morris, Paul F -- Phuntumart, Vipaporn -- Putnam, Nicholas H -- Rash, Sam -- Rose, Jocelyn K C -- Sakihama, Yasuko -- Salamov, Asaf A -- Savidor, Alon -- Scheuring, Chantel F -- Smith, Brian M -- Sobral, Bruno W S -- Terry, Astrid -- Torto-Alalibo, Trudy A -- Win, Joe -- Xu, Zhanyou -- Zhang, Hongbin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Boore, Jeffrey L -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1261-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Virginia Bioinformatics Institute, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA. bmtyler@vt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946064" target="_blank"〉PubMed〈/a〉

    Sequencing and analysis of Neanderthal genomic DNA (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-18
    Description: Our knowledge of Neanderthals is based on a limited number of remains and artifacts from which we must make inferences about their biology, behavior, and relationship to ourselves. Here, we describe the characterization of these extinct hominids from a new perspective, based on the development of a Neanderthal metagenomic library and its high-throughput sequencing and analysis. Several lines of evidence indicate that the 65,250 base pairs of hominid sequence so far identified in the library are of Neanderthal origin, the strongest being the ascertainment of sequence identities between Neanderthal and chimpanzee at sites where the human genomic sequence is different. These results enabled us to calculate the human-Neanderthal divergence time based on multiple randomly distributed autosomal loci. Our analyses suggest that on average the Neanderthal genomic sequence we obtained and the reference human genome sequence share a most recent common ancestor approximately 706,000 years ago, and that the human and Neanderthal ancestral populations split approximately 370,000 years ago, before the emergence of anatomically modern humans. Our finding that the Neanderthal and human genomes are at least 99.5% identical led us to develop and successfully implement a targeted method for recovering specific ancient DNA sequences from metagenomic libraries. This initial analysis of the Neanderthal genome advances our understanding of the evolutionary relationship of Homo sapiens and Homo neanderthalensis and signifies the dawn of Neanderthal genomics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2583069/" 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/PMC2583069/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noonan, James P -- Coop, Graham -- Kudaravalli, Sridhar -- Smith, Doug -- Krause, Johannes -- Alessi, Joe -- Chen, Feng -- Platt, Darren -- Paabo, Svante -- Pritchard, Jonathan K -- Rubin, Edward M -- 1-F32-GM074367/GM/NIGMS NIH HHS/ -- HL066681/HL/NHLBI NIH HHS/ -- R01 HG002772/HG/NHGRI NIH HHS/ -- R01 HG002772-01/HG/NHGRI NIH HHS/ -- R01 HG002772-1/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 17;314(5802):1113-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17110569" target="_blank"〉PubMed〈/a〉

    Comment on "Statistical independence of escalatory ecological trends in Phanerozoic marine invertebrates" (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-11
    Description: The analysis of Madin et al. (Reports, 12 May 2006, p. 897) of Phanerozoic diversity failed to support expected correlations between carnivores and noncarnivores, leading the authors to reject escalation as an important macroevolutionary process. The test, however, is based on a flawed model of causality, and the ecological groups are improperly delineated with regard to the hypothesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roopnarine, Peter D -- Angielczyk, Kenneth D -- Hertog, Rachel -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):925; author reply 925.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Invertebrate Zoology and Geology, California Academy of Sciences, 875 Howard Street, San Francisco, CA 94103, USA. proopnarine@calacademy.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095679" target="_blank"〉PubMed〈/a〉

    Late Precambrian oxygenation; inception of the clay mineral factory (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-04
    Description: An enigmatic stepwise increase in oxygen in the late Precambrian is widely considered a prerequisite for the expansion of animal life. Accumulation of oxygen requires organic matter burial in sediments, which is largely controlled by the sheltering or preservational effects of detrital clay minerals in modern marine continental margin depocenters. Here, we show mineralogical and geochemical evidence for an increase in clay mineral deposition in the Neoproterozoic that immediately predated the first metazoans. Today most clay minerals originate in biologically active soils, so initial expansion of a primitive land biota would greatly enhance production of pedogenic clay minerals (the "clay mineral factory"), leading to increased marine burial of organic carbon via mineral surface preservation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kennedy, Martin -- Droser, Mary -- Mayer, Lawrence M -- Pevear, David -- Mrofka, David -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1446-9.

    Gene regulatory networks and the evolution of animal body plans (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-14
    Description: Development of the animal body plan is controlled by large gene regulatory networks (GRNs), and hence evolution of body plans must depend upon change in the architecture of developmental GRNs. However, these networks are composed of diverse components that evolve at different rates and in different ways. Because of the hierarchical organization of developmental GRNs, some kinds of change affect terminal properties of the body plan such as occur in speciation, whereas others affect major aspects of body plan morphology. A notable feature of the paleontological record of animal evolution is the establishment by the Early "Cambrian of virtually all phylum-level body plans. We identify a class of GRN component, the kernels" of the network, which, because of their developmental role and their particular internal structure, are most impervious to change. Conservation of phyletic body plans may have been due to the retention since pre-Cambrian time of GRN kernels, which underlie development of major body parts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davidson, Eric H -- Erwin, Douglas H -- HD37105/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):796-800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology 156-29, California Institute of Technology, Pasadena, CA 91125, USA. davidson@caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469913" target="_blank"〉PubMed〈/a〉

    An equivalence principle for the incorporation of favorable mutations in asexual populations (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-03-18
    Description: Rapid evolution of asexual populations, such as that of cancer cells or of microorganisms developing drug resistance, can include the simultaneous spread of distinct beneficial mutations. We demonstrate that evolution in such cases is driven by the fitness effects and appearance times of only a small minority of favorable mutations. The complexity of the mutation-selection process is thereby greatly reduced, and much of the evolutionary dynamics can be encapsulated in two parameters-an effective selection coefficient and effective rate of beneficial mutations. We confirm this theoretical finding and estimate the effective parameters for evolving populations of fluorescently labeled Escherichia coli. The effective parameters constitute a simple description and provide a natural standard for comparing adaptation between species and across environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hegreness, Matthew -- Shoresh, Noam -- Hartl, Daniel -- Kishony, Roy -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1615-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bauer Center for Genomics Research, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16543462" target="_blank"〉PubMed〈/a〉

    Lower Cambrian vendobionts from China and early diploblast evolution (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-06
    Description: Ediacaran assemblages immediately predate the Cambrian explosion of metazoans and should have played a crucial role in this radiation. Their wider relationships, however, have remained refractory and difficult to integrate with early metazoan phylogeny. Here, we describe a frondlike fossil, Stromatoveris (S. psygmoglena sp. nov.), from the Lower Cambrian Chengjiang Lagerstatte (Yunnan, China) that is strikingly similar to Ediacaran vendobionts. The exquisite preservation reveals closely spaced branches, probably ciliated, that appear to represent precursors of the diagnostic comb rows of ctenophores. Therefore, this finding has important implications for the early evolution of this phylum and related diploblasts, some of which independently evolved a frondose habit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shu, D-G -- Morris, S Conway -- Han, J -- Li, Y -- Zhang, X-L -- Hua, H -- Zhang, Z-F -- Liu, J-N -- Guo, J-F -- Yao, Y -- Yasui, K -- New York, N.Y. -- Science. 2006 May 5;312(5774):731-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Early Life Institute and Key Laboratory of Continental Dynamics, Northwest University, Xi'an 710069, China. elidgshu@nwu.edu.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16675697" target="_blank"〉PubMed〈/a〉
