Description:
The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the African coelacanth, Latimeria chalumnae. Through a phylogenomic analysis, we conclude that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Coelacanth protein-coding genes are significantly more slowly evolving than those of tetrapods, unlike other genomic features. Analyses of changes in genes and regulatory elements during the vertebrate adaptation to land highlight genes involved in immunity, nitrogen excretion and the development of fins, tail, ear, eye, brain and olfaction. Functional assays of enhancers involved in the fin-to-limb transition and in the emergence of extra-embryonic tissues show the importance of the coelacanth genome as a blueprint for understanding tetrapod evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3633110/" 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/PMC3633110/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amemiya, Chris T -- Alfoldi, Jessica -- Lee, Alison P -- Fan, Shaohua -- Philippe, Herve -- Maccallum, Iain -- Braasch, Ingo -- Manousaki, Tereza -- Schneider, Igor -- Rohner, Nicolas -- Organ, Chris -- Chalopin, Domitille -- Smith, Jeramiah J -- Robinson, Mark -- Dorrington, Rosemary A -- Gerdol, Marco -- Aken, Bronwen -- Biscotti, Maria Assunta -- Barucca, Marco -- Baurain, Denis -- Berlin, Aaron M -- Blatch, Gregory L -- Buonocore, Francesco -- Burmester, Thorsten -- Campbell, Michael S -- Canapa, Adriana -- Cannon, John P -- Christoffels, Alan -- De Moro, Gianluca -- Edkins, Adrienne L -- Fan, Lin -- Fausto, Anna Maria -- Feiner, Nathalie -- Forconi, Mariko -- Gamieldien, Junaid -- Gnerre, Sante -- Gnirke, Andreas -- Goldstone, Jared V -- Haerty, Wilfried -- Hahn, Mark E -- Hesse, Uljana -- Hoffmann, Steve -- Johnson, Jeremy -- Karchner, Sibel I -- Kuraku, Shigehiro -- Lara, Marcia -- Levin, Joshua Z -- Litman, Gary W -- Mauceli, Evan -- Miyake, Tsutomu -- Mueller, M Gail -- Nelson, David R -- Nitsche, Anne -- Olmo, Ettore -- Ota, Tatsuya -- Pallavicini, Alberto -- Panji, Sumir -- Picone, Barbara -- Ponting, Chris P -- Prohaska, Sonja J -- Przybylski, Dariusz -- Saha, Nil Ratan -- Ravi, Vydianathan -- Ribeiro, Filipe J -- Sauka-Spengler, Tatjana -- Scapigliati, Giuseppe -- Searle, Stephen M J -- Sharpe, Ted -- Simakov, Oleg -- Stadler, Peter F -- Stegeman, John J -- Sumiyama, Kenta -- Tabbaa, Diana -- Tafer, Hakim -- Turner-Maier, Jason -- van Heusden, Peter -- White, Simon -- Williams, Louise -- Yandell, Mark -- Brinkmann, Henner -- Volff, Jean-Nicolas -- Tabin, Clifford J -- Shubin, Neil -- Schartl, Manfred -- Jaffe, David B -- Postlethwait, John H -- Venkatesh, Byrappa -- Di Palma, Federica -- Lander, Eric S -- Meyer, Axel -- Lindblad-Toh, Kerstin -- 095908/Wellcome Trust/United Kingdom -- MC_U137761446/Medical Research Council/United Kingdom -- P42 ES007381/ES/NIEHS NIH HHS/ -- R01 ES006272/ES/NIEHS NIH HHS/ -- R01 HG003474/HG/NHGRI NIH HHS/ -- R01 OD011116/OD/NIH HHS/ -- R24 OD011199/OD/NIH HHS/ -- R24 RR032670/RR/NCRR NIH HHS/ -- R37 HD032443/HD/NICHD NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- England -- Nature. 2013 Apr 18;496(7445):311-6. doi: 10.1038/nature12027.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics Program, Benaroya Research Institute, Seattle, Washington 98101, USA. camemiya@benaroyaresearch.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23598338" target="_blank"〉PubMed〈/a〉
