    Archaeorhizomycetes: unearthing an ancient class of ubiquitous soil fungi (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-08-13
    Description: Estimates suggest that only one-tenth of the true fungal diversity has been described. Among numerous fungal lineages known only from environmental DNA sequences, Soil Clone Group 1 is the most ubiquitous. These globally distributed fungi may dominate below-ground fungal communities, but their placement in the fungal tree of life has been uncertain. Here, we report cultures of this group and describe the class, Archaeorhizomycetes, phylogenetically placed within subphylum Taphrinomycotina in the Ascomycota. Archaeorhizomycetes comprises hundreds of cryptically reproducing filamentous species that do not form recognizable mycorrhizal structures and have saprotrophic potential, yet are omnipresent in roots and rhizosphere soil and show ecosystem and host root habitat specificity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosling, Anna -- Cox, Filipa -- Cruz-Martinez, Karelyn -- Ihrmark, Katarina -- Grelet, Gwen-Aelle -- Lindahl, Bjorn D -- Menkis, Audrius -- James, Timothy Y -- New York, N.Y. -- Science. 2011 Aug 12;333(6044):876-9. doi: 10.1126/science.1206958.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Forest Mycology and Pathology, Uppsala BioCentre, SLU, Box 7026, 750 07 Uppsala, Sweden. anna.rosling@slu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21836015" target="_blank"〉PubMed〈/a〉

    Five-vertebrate ChIP-seq reveals the evolutionary dynamics of transcription factor binding (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-04-10
    Description: Transcription factors (TFs) direct gene expression by binding to DNA regulatory regions. To explore the evolution of gene regulation, we used chromatin immunoprecipitation with high-throughput sequencing (ChIP-seq) to determine experimentally the genome-wide occupancy of two TFs, CCAAT/enhancer-binding protein alpha and hepatocyte nuclear factor 4 alpha, in the livers of five vertebrates. Although each TF displays highly conserved DNA binding preferences, most binding is species-specific, and aligned binding events present in all five species are rare. Regions near genes with expression levels that are dependent on a TF are often bound by the TF in multiple species yet show no enhanced DNA sequence constraint. Binding divergence between species can be largely explained by sequence changes to the bound motifs. Among the binding events lost in one lineage, only half are recovered by another binding event within 10 kilobases. Our results reveal large interspecies differences in transcriptional regulation and provide insight into regulatory evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmidt, Dominic -- Wilson, Michael D -- Ballester, Benoit -- Schwalie, Petra C -- Brown, Gordon D -- Marshall, Aileen -- Kutter, Claudia -- Watt, Stephen -- Martinez-Jimenez, Celia P -- Mackay, Sarah -- Talianidis, Iannis -- Flicek, Paul -- Odom, Duncan T -- 062023/Wellcome Trust/United Kingdom -- 079643/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- WT062023/Wellcome Trust/United Kingdom -- WT079643/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2010 May 21;328(5981):1036-40. doi: 10.1126/science.1186176.

    Erosion of lizard diversity by climate change and altered thermal niches (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-05-15
    Description: It is predicted that climate change will cause species extinctions and distributional shifts in coming decades, but data to validate these predictions are relatively scarce. Here, we compare recent and historical surveys for 48 Mexican lizard species at 200 sites. Since 1975, 12% of local populations have gone extinct. We verified physiological models of extinction risk with observed local extinctions and extended projections worldwide. Since 1975, we estimate that 4% of local populations have gone extinct worldwide, but by 2080 local extinctions are projected to reach 39% worldwide, and species extinctions may reach 20%. Global extinction projections were validated with local extinctions observed from 1975 to 2009 for regional biotas on four other continents, suggesting that lizards have already crossed a threshold for extinctions caused by climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sinervo, Barry -- Mendez-de-la-Cruz, Fausto -- Miles, Donald B -- Heulin, Benoit -- Bastiaans, Elizabeth -- Villagran-Santa Cruz, Maricela -- Lara-Resendiz, Rafael -- Martinez-Mendez, Norberto -- Calderon-Espinosa, Martha Lucia -- Meza-Lazaro, Rubi Nelsi -- Gadsden, Hector -- Avila, Luciano Javier -- Morando, Mariana -- De la Riva, Ignacio J -- Victoriano Sepulveda, Pedro -- Rocha, Carlos Frederico Duarte -- Ibarguengoytia, Nora -- Aguilar Puntriano, Cesar -- Massot, Manuel -- Lepetz, Virginie -- Oksanen, Tuula A -- Chapple, David G -- Bauer, Aaron M -- Branch, William R -- Clobert, Jean -- Sites, Jack W Jr -- New York, N.Y. -- Science. 2010 May 14;328(5980):894-9. doi: 10.1126/science.1184695.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95064, USA. lizardrps@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20466932" target="_blank"〉PubMed〈/a〉

    Potential for chemolithoautotrophy among ubiquitous bacteria lineages in the dark ocean (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-09-03
    Description: Recent studies suggest that unidentified prokaryotes fix inorganic carbon at globally significant rates in the immense dark ocean. Using single-cell sorting and whole-genome amplification of prokaryotes from two subtropical gyres, we obtained genomic DNA from 738 cells representing most cosmopolitan lineages. Multiple cells of Deltaproteobacteria cluster SAR324, Gammaproteobacteria clusters ARCTIC96BD-19 and Agg47, and some Oceanospirillales from the lower mesopelagic contained ribulose-1,5-bisphosphate carboxylase-oxygenase and sulfur oxidation genes. These results corroborated community DNA and RNA profiling from diverse geographic regions. The SAR324 genomes also suggested C(1) metabolism and a particle-associated life-style. Microautoradiography and fluorescence in situ hybridization confirmed bicarbonate uptake and particle association of SAR324 cells. Our study suggests potential chemolithoautotrophy in several uncultured Proteobacteria lineages that are ubiquitous in the dark oxygenated ocean and provides new perspective on carbon cycling in the ocean's largest habitat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swan, Brandon K -- Martinez-Garcia, Manuel -- Preston, Christina M -- Sczyrba, Alexander -- Woyke, Tanja -- Lamy, Dominique -- Reinthaler, Thomas -- Poulton, Nicole J -- Masland, E Dashiell P -- Gomez, Monica Lluesma -- Sieracki, Michael E -- DeLong, Edward F -- Herndl, Gerhard J -- Stepanauskas, Ramunas -- New York, N.Y. -- Science. 2011 Sep 2;333(6047):1296-300. doi: 10.1126/science.1203690.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bigelow Laboratory for Ocean Sciences, 180 McKown Point Road, Post Office Box 475, West Boothbay Harbor, ME 04575, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21885783" target="_blank"〉PubMed〈/a〉

    A basal dinosaur from the dawn of the dinosaur era in southwestern Pangaea (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-01-15
    Description: Upper Triassic rocks in northwestern Argentina preserve the most complete record of dinosaurs before their rise to dominance in the Early Jurassic. Here, we describe a previously unidentified basal theropod, reassess its contemporary Eoraptor as a basal sauropodomorph, divide the faunal record of the Ischigualasto Formation with biozones, and bracket the formation with (40)Ar/(39)Ar ages. Some 230 million years ago in the Late Triassic (mid Carnian), the earliest dinosaurs were the dominant terrestrial carnivores and small herbivores in southwestern Pangaea. The extinction of nondinosaurian herbivores is sequential and is not linked to an increase in dinosaurian diversity, which weakens the predominant scenario for dinosaurian ascendancy as opportunistic replacement.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez, Ricardo N -- Sereno, Paul C -- Alcober, Oscar A -- Colombi, Carina E -- Renne, Paul R -- Montanez, Isabel P -- Currie, Brian S -- New York, N.Y. -- Science. 2011 Jan 14;331(6014):206-10. doi: 10.1126/science.1198467.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Instituto y Museo de Ciencias Naturales, Universidad Nacional de San Juan, San Juan 5400, Argentina.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21233386" target="_blank"〉PubMed〈/a〉
