    Description: Many oomycete and fungal plant pathogens are obligate biotrophs, which extract nutrients only from living plant tissue and cannot grow apart from their hosts. Although these pathogens cause substantial crop losses, little is known about the molecular basis or evolution of obligate biotrophy. Here, we report the genome sequence of the oomycete Hyaloperonospora arabidopsidis (Hpa), an obligate biotroph and natural pathogen of Arabidopsis thaliana. In comparison with genomes of related, hemibiotrophic Phytophthora species, the Hpa genome exhibits dramatic reductions in genes encoding (i) RXLR effectors and other secreted pathogenicity proteins, (ii) enzymes for assimilation of inorganic nitrogen and sulfur, and (iii) proteins associated with zoospore formation and motility. These attributes comprise a genomic signature of evolution toward obligate biotrophy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3971456/" 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/PMC3971456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baxter, Laura -- Tripathy, Sucheta -- Ishaque, Naveed -- Boot, Nico -- Cabral, Adriana -- Kemen, Eric -- Thines, Marco -- Ah-Fong, Audrey -- Anderson, Ryan -- Badejoko, Wole -- Bittner-Eddy, Peter -- Boore, Jeffrey L -- Chibucos, Marcus C -- Coates, Mary -- Dehal, Paramvir -- Delehaunty, Kim -- Dong, Suomeng -- Downton, Polly -- Dumas, Bernard -- Fabro, Georgina -- Fronick, Catrina -- Fuerstenberg, Susan I -- Fulton, Lucinda -- Gaulin, Elodie -- Govers, Francine -- Hughes, Linda -- Humphray, Sean -- Jiang, Rays H Y -- Judelson, Howard -- Kamoun, Sophien -- Kyung, Kim -- Meijer, Harold -- Minx, Patrick -- Morris, Paul -- Nelson, Joanne -- Phuntumart, Vipa -- Qutob, Dinah -- Rehmany, Anne -- Rougon-Cardoso, Alejandra -- Ryden, Peter -- Torto-Alalibo, Trudy -- Studholme, David -- Wang, Yuanchao -- Win, Joe -- Wood, Jo -- Clifton, Sandra W -- Rogers, Jane -- Van den Ackerveken, Guido -- Jones, Jonathan D G -- McDowell, John M -- Beynon, Jim -- Tyler, Brett M -- 079643/Wellcome Trust/United Kingdom -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E007120/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024815/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024882/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F0161901/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G015244/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- EP/F500025/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- T12144/Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1549-51. doi: 10.1126/science.1195203.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, Warwick University, Wellesbourne, CV35 9EF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148394" target="_blank"〉PubMed〈/a〉

    Description: Transcription factors (TFs) are key players in evolution. Changes affecting their function can yield novel life forms but may also have deleterious effects. Consequently, gene duplication events that release one gene copy from selective pressure are thought to be the common mechanism by which TFs acquire new activities. Here, we show that LEAFY, a major regulator of flower development and cell division in land plants, underwent changes to its DNA binding specificity, even though plant genomes generally contain a single copy of the LEAFY gene. We examined how these changes occurred at the structural level and identify an intermediate LEAFY form in hornworts that appears to adopt all different specificities. This promiscuous intermediate could have smoothed the evolutionary transitions, thereby allowing LEAFY to evolve new binding specificities while remaining a single-copy gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sayou, Camille -- Monniaux, Marie -- Nanao, Max H -- Moyroud, Edwige -- Brockington, Samuel F -- Thevenon, Emmanuel -- Chahtane, Hicham -- Warthmann, Norman -- Melkonian, Michael -- Zhang, Yong -- Wong, Gane Ka-Shu -- Weigel, Detlef -- Parcy, Francois -- Dumas, Renaud -- New York, N.Y. -- Science. 2014 Feb 7;343(6171):645-8. doi: 10.1126/science.1248229.

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

    Description: Extreme gene duplication is a major source of evolutionary novelty. A genome-wide survey of gene copy number variation among human and great ape lineages revealed that the most striking human lineage-specific amplification was due to an unknown gene, MGC8902, which is predicted to encode multiple copies of a protein domain of unknown function (DUF1220). Sequences encoding these domains are virtually all primate-specific, show signs of positive selection, and are increasingly amplified generally as a function of a species' evolutionary proximity to humans, where the greatest number of copies (212) is found. DUF1220 domains are highly expressed in brain regions associated with higher cognitive function, and in brain show neuron-specific expression preferentially in cell bodies and dendrites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popesco, Magdalena C -- Maclaren, Erik J -- Hopkins, Janet -- Dumas, Laura -- Cox, Michael -- Meltesen, Lynne -- McGavran, Loris -- Wyckoff, Gerald J -- Sikela, James M -- AA11853/AA/NIAAA NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1304-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Medical Genetics, University of Colorado at Denver and Health Sciences Center, Aurora, CO 80045, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946073" target="_blank"〉PubMed〈/a〉
