    Description: Lancelets ('amphioxus') are the modern survivors of an ancient chordate lineage, with a fossil record dating back to the Cambrian period. Here we describe the structure and gene content of the highly polymorphic approximately 520-megabase genome of the Florida lancelet Branchiostoma floridae, and analyse it in the context of chordate evolution. Whole-genome comparisons illuminate the murky relationships among the three chordate groups (tunicates, lancelets and vertebrates), and allow not only reconstruction of the gene complement of the last common chordate ancestor but also partial reconstruction of its genomic organization, as well as a description of two genome-wide duplications and subsequent reorganizations in the vertebrate lineage. These genome-scale events shaped the vertebrate genome and provided additional genetic variation for exploitation during vertebrate evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putnam, Nicholas H -- Butts, Thomas -- Ferrier, David E K -- Furlong, Rebecca F -- Hellsten, Uffe -- Kawashima, Takeshi -- Robinson-Rechavi, Marc -- Shoguchi, Eiichi -- Terry, Astrid -- Yu, Jr-Kai -- Benito-Gutierrez, E Lia -- Dubchak, Inna -- Garcia-Fernandez, Jordi -- Gibson-Brown, Jeremy J -- Grigoriev, Igor V -- Horton, Amy C -- de Jong, Pieter J -- Jurka, Jerzy -- Kapitonov, Vladimir V -- Kohara, Yuji -- Kuroki, Yoko -- Lindquist, Erika -- Lucas, Susan -- Osoegawa, Kazutoyo -- Pennacchio, Len A -- Salamov, Asaf A -- Satou, Yutaka -- Sauka-Spengler, Tatjana -- Schmutz, Jeremy -- Shin-I, Tadasu -- Toyoda, Atsushi -- Bronner-Fraser, Marianne -- Fujiyama, Asao -- Holland, Linda Z -- Holland, Peter W H -- Satoh, Nori -- Rokhsar, Daniel S -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Jun 19;453(7198):1064-71. doi: 10.1038/nature06967.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18563158" target="_blank"〉PubMed〈/a〉

    Description: Sea anemones are seemingly primitive animals that, along with corals, jellyfish, and hydras, constitute the oldest eumetazoan phylum, the Cnidaria. Here, we report a comparative analysis of the draft genome of an emerging cnidarian model, the starlet sea anemone Nematostella vectensis. The sea anemone genome is complex, with a gene repertoire, exon-intron structure, and large-scale gene linkage more similar to vertebrates than to flies or nematodes, implying that the genome of the eumetazoan ancestor was similarly complex. Nearly one-fifth of the inferred genes of the ancestor are eumetazoan novelties, which are enriched for animal functions like cell signaling, adhesion, and synaptic transmission. Analysis of diverse pathways suggests that these gene "inventions" along the lineage leading to animals were likely already well integrated with preexisting eukaryotic genes in the eumetazoan progenitor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Putnam, Nicholas H -- Srivastava, Mansi -- Hellsten, Uffe -- Dirks, Bill -- Chapman, Jarrod -- Salamov, Asaf -- Terry, Astrid -- Shapiro, Harris -- Lindquist, Erika -- Kapitonov, Vladimir V -- Jurka, Jerzy -- Genikhovich, Grigory -- Grigoriev, Igor V -- Lucas, Susan M -- Steele, Robert E -- Finnerty, John R -- Technau, Ulrich -- Martindale, Mark Q -- Rokhsar, Daniel S -- 5 P41 LM006252-09/LM/NLM NIH HHS/ -- THL007279F/PHS HHS/ -- New York, N.Y. -- Science. 2007 Jul 6;317(5834):86-94.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17615350" target="_blank"〉PubMed〈/a〉

    Description: The western clawed frog Xenopus tropicalis is an important model for vertebrate development that combines experimental advantages of the African clawed frog Xenopus laevis with more tractable genetics. Here we present a draft genome sequence assembly of X. tropicalis. This genome encodes more than 20,000 protein-coding genes, including orthologs of at least 1700 human disease genes. Over 1 million expressed sequence tags validated the annotation. More than one-third of the genome consists of transposable elements, with unusually prevalent DNA transposons. Like that of other tetrapods, the genome of X. tropicalis contains gene deserts enriched for conserved noncoding elements. The genome exhibits substantial shared synteny with human and chicken over major parts of large chromosomes, broken by lineage-specific chromosome fusions and fissions, mainly in the mammalian lineage.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2994648/" 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/PMC2994648/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hellsten, Uffe -- Harland, Richard M -- Gilchrist, Michael J -- Hendrix, David -- Jurka, Jerzy -- Kapitonov, Vladimir -- Ovcharenko, Ivan -- Putnam, Nicholas H -- Shu, Shengqiang -- Taher, Leila -- Blitz, Ira L -- Blumberg, Bruce -- Dichmann, Darwin S -- Dubchak, Inna -- Amaya, Enrique -- Detter, John C -- Fletcher, Russell -- Gerhard, Daniela S -- Goodstein, David -- Graves, Tina -- Grigoriev, Igor V -- Grimwood, Jane -- Kawashima, Takeshi -- Lindquist, Erika -- Lucas, Susan M -- Mead, Paul E -- Mitros, Therese -- Ogino, Hajime -- Ohta, Yuko -- Poliakov, Alexander V -- Pollet, Nicolas -- Robert, Jacques -- Salamov, Asaf -- Sater, Amy K -- Schmutz, Jeremy -- Terry, Astrid -- Vize, Peter D -- Warren, Wesley C -- Wells, Dan -- Wills, Andrea -- Wilson, Richard K -- Zimmerman, Lyle B -- Zorn, Aaron M -- Grainger, Robert -- Grammer, Timothy -- Khokha, Mustafa K -- Richardson, Paul M -- Rokhsar, Daniel S -- HHSN261200800001E/CA/NCI NIH HHS/ -- MC_U117560482/Medical Research Council/United Kingdom -- P41 HD064556/HD/NICHD NIH HHS/ -- P41 HD064556-01/HD/NICHD NIH HHS/ -- P41 HD064556-02/HD/NICHD NIH HHS/ -- R01 AI027877/AI/NIAID NIH HHS/ -- R01 AI027877-20/AI/NIAID NIH HHS/ -- R01 DK070858/DK/NIDDK NIH HHS/ -- R01 DK070858-05/DK/NIDDK NIH HHS/ -- R01 EY018000/EY/NEI NIH HHS/ -- R01 EY018000-03/EY/NEI NIH HHS/ -- R01 GM060572/GM/NIGMS NIH HHS/ -- R01 GM060572-05/GM/NIGMS NIH HHS/ -- R01 GM086321/GM/NIGMS NIH HHS/ -- R01 GM086321-03/GM/NIGMS NIH HHS/ -- R01 HD042294/HD/NICHD NIH HHS/ -- R01 HD042294-05/HD/NICHD NIH HHS/ -- R01 HD045776/HD/NICHD NIH HHS/ -- R01 HD045776-05/HD/NICHD NIH HHS/ -- R01 HD046661-03/HD/NICHD NIH HHS/ -- R01 MH079381/MH/NIMH NIH HHS/ -- R01 MH079381-02/MH/NIMH NIH HHS/ -- R21 HD065713/HD/NICHD NIH HHS/ -- R24 AI059830/AI/NIAID NIH HHS/ -- R24 AI059830-08/AI/NIAID NIH HHS/ -- R24 RR015088/RR/NCRR NIH HHS/ -- R24 RR015088-03/RR/NCRR NIH HHS/ -- U01 HG002155-05/HG/NHGRI NIH HHS/ -- U01 HG02155/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):633-6. doi: 10.1126/science.1183670.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy Joint Genome Institute, Walnut Creek, CA 94598, USA. uhellsten@lbl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431018" target="_blank"〉PubMed〈/a〉

    Description: The multicellular green alga Volvox carteri and its morphologically diverse close relatives (the volvocine algae) are well suited for the investigation of the evolution of multicellularity and development. We sequenced the 138-mega-base pair genome of V. carteri and compared its approximately 14,500 predicted proteins to those of its unicellular relative Chlamydomonas reinhardtii. Despite fundamental differences in organismal complexity and life history, the two species have similar protein-coding potentials and few species-specific protein-coding gene predictions. Volvox is enriched in volvocine-algal-specific proteins, including those associated with an expanded and highly compartmentalized extracellular matrix. Our analysis shows that increases in organismal complexity can be associated with modifications of lineage-specific proteins rather than large-scale invention of protein-coding capacity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2993248/" 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/PMC2993248/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prochnik, Simon E -- Umen, James -- Nedelcu, Aurora M -- Hallmann, Armin -- Miller, Stephen M -- Nishii, Ichiro -- Ferris, Patrick -- Kuo, Alan -- Mitros, Therese -- Fritz-Laylin, Lillian K -- Hellsten, Uffe -- Chapman, Jarrod -- Simakov, Oleg -- Rensing, Stefan A -- Terry, Astrid -- Pangilinan, Jasmyn -- Kapitonov, Vladimir -- Jurka, Jerzy -- Salamov, Asaf -- Shapiro, Harris -- Schmutz, Jeremy -- Grimwood, Jane -- Lindquist, Erika -- Lucas, Susan -- Grigoriev, Igor V -- Schmitt, Rudiger -- Kirk, David -- Rokhsar, Daniel S -- 5 P41 LM006252/LM/NLM NIH HHS/ -- R01 GM078376/GM/NIGMS NIH HHS/ -- R01 GM078376-01/GM/NIGMS NIH HHS/ -- R01 GM078376-02/GM/NIGMS NIH HHS/ -- R01 GM078376-03/GM/NIGMS NIH HHS/ -- R01 GM078376-04/GM/NIGMS NIH HHS/ -- R01 GM078376-04S1/GM/NIGMS NIH HHS/ -- R01 GM078376-05/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 9;329(5988):223-6. doi: 10.1126/science.1188800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy, Joint Genome Institute, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20616280" target="_blank"〉PubMed〈/a〉
