Description:
Choanoflagellates are the closest known relatives of metazoans. To discover potential molecular mechanisms underlying the evolution of metazoan multicellularity, we sequenced and analysed the genome of the unicellular choanoflagellate Monosiga brevicollis. The genome contains approximately 9,200 intron-rich genes, including a number that encode cell adhesion and signalling protein domains that are otherwise restricted to metazoans. Here we show that the physical linkages among protein domains often differ between M. brevicollis and metazoans, suggesting that abundant domain shuffling followed the separation of the choanoflagellate and metazoan lineages. The completion of the M. brevicollis genome allows us to reconstruct with increasing resolution the genomic changes that accompanied the origin of metazoans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2562698/" 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/PMC2562698/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉King, Nicole -- Westbrook, M Jody -- Young, Susan L -- Kuo, Alan -- Abedin, Monika -- Chapman, Jarrod -- Fairclough, Stephen -- Hellsten, Uffe -- Isogai, Yoh -- Letunic, Ivica -- Marr, Michael -- Pincus, David -- Putnam, Nicholas -- Rokas, Antonis -- Wright, Kevin J -- Zuzow, Richard -- Dirks, William -- Good, Matthew -- Goodstein, David -- Lemons, Derek -- Li, Wanqing -- Lyons, Jessica B -- Morris, Andrea -- Nichols, Scott -- Richter, Daniel J -- Salamov, Asaf -- Sequencing, J G I -- Bork, Peer -- Lim, Wendell A -- Manning, Gerard -- Miller, W Todd -- McGinnis, William -- Shapiro, Harris -- Tjian, Robert -- Grigoriev, Igor V -- Rokhsar, Daniel -- R01 CA058530/CA/NCI NIH HHS/ -- R01 CA058530-14/CA/NCI NIH HHS/ -- R01 GM077197/GM/NIGMS NIH HHS/ -- R01 HG004164/HG/NHGRI NIH HHS/ -- R01 HG004164-01/HG/NHGRI NIH HHS/ -- R37 HD028315/HD/NICHD NIH HHS/ -- England -- Nature. 2008 Feb 14;451(7180):783-8. doi: 10.1038/nature06617.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology and the Center for Integrative Genomics, University of California, Berkeley, California 94720, USA. nking@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18273011" target="_blank"〉PubMed〈/a〉
