    Description: Despite a rapid increase in the amount of available archaeal sequence information, little is known about the duplication of genetic material in the third domain of life. We identified a single origin of bidirectional replication in Pyrococcus abyssi by means of in silico analyses of cumulative oligomer skew and the identification of an early replicating chromosomal segment. The replication origin in three Pyrococcus species was found to be highly conserved, and several eukaryotic-like DNA replication genes were clustered around it. As in Bacteria, the chromosomal region containing the replication terminus was a hot spot of genome shuffling. Thus, although bacterial and archaeal replication proteins differ profoundly, they are used to replicate chromosomes in a similar manner in both prokaryotic domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myllykallio, H -- Lopez, P -- Lopez-Garcia, P -- Heilig, R -- Saurin, W -- Zivanovic, Y -- Philippe, H -- Forterre, P -- New York, N.Y. -- Science. 2000 Jun 23;288(5474):2212-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Genetique et Microbiologie, Laboratoire de Biologie Cellulaire, Universite de Paris-Sud, 91405 Orsay Cedex, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10864870" target="_blank"〉PubMed〈/a〉

    Description: Genomes of animals as different as sponges and humans show conservation of global architecture. Here we show that multiple genomic features including transposon diversity, developmental gene repertoire, physical gene order, and intron-exon organization are shattered in the tunicate Oikopleura, belonging to the sister group of vertebrates and retaining chordate morphology. Ancestral architecture of animal genomes can be deeply modified and may therefore be largely nonadaptive. This rapidly evolving animal lineage thus offers unique perspectives on the level of genome plasticity. It also illuminates issues as fundamental as the mechanisms of intron gain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3760481/" 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/PMC3760481/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Denoeud, France -- Henriet, Simon -- Mungpakdee, Sutada -- Aury, Jean-Marc -- Da Silva, Corinne -- Brinkmann, Henner -- Mikhaleva, Jana -- Olsen, Lisbeth Charlotte -- Jubin, Claire -- Canestro, Cristian -- Bouquet, Jean-Marie -- Danks, Gemma -- Poulain, Julie -- Campsteijn, Coen -- Adamski, Marcin -- Cross, Ismael -- Yadetie, Fekadu -- Muffato, Matthieu -- Louis, Alexandra -- Butcher, Stephen -- Tsagkogeorga, Georgia -- Konrad, Anke -- Singh, Sarabdeep -- Jensen, Marit Flo -- Huynh Cong, Evelyne -- Eikeseth-Otteraa, Helen -- Noel, Benjamin -- Anthouard, Veronique -- Porcel, Betina M -- Kachouri-Lafond, Rym -- Nishino, Atsuo -- Ugolini, Matteo -- Chourrout, Pascal -- Nishida, Hiroki -- Aasland, Rein -- Huzurbazar, Snehalata -- Westhof, Eric -- Delsuc, Frederic -- Lehrach, Hans -- Reinhardt, Richard -- Weissenbach, Jean -- Roy, Scott W -- Artiguenave, Francois -- Postlethwait, John H -- Manak, J Robert -- Thompson, Eric M -- Jaillon, Olivier -- Du Pasquier, Louis -- Boudinot, Pierre -- Liberles, David A -- Volff, Jean-Nicolas -- Philippe, Herve -- Lenhard, Boris -- Roest Crollius, Hugues -- Wincker, Patrick -- Chourrout, Daniel -- Z01 LM000073-12/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 3;330(6009):1381-5. doi: 10.1126/science.1194167.

    Description: A major evolutionary divide occurs in the animal kingdom between the so-called radially symmetric animals, which includes the cnidarians, and the bilaterally symmetric animals, which includes all worm phyla. Buddenbrockia plumatellae is an active, muscular, parasitic worm that belongs to the phylum Myxozoa, a group of morphologically simplified microscopic endoparasites that has proved difficult to place phylogenetically. Phylogenetic analyses of multiple protein-coding genes demonstrate that Buddenbrockia is a cnidarian. This active muscular worm increases the known diversity in cnidarian body plans and demonstrates that a muscular, wormlike form can evolve in the absence of overt bilateral symmetry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jimenez-Guri, Eva -- Philippe, Herve -- Okamura, Beth -- Holland, Peter W H -- New York, N.Y. -- Science. 2007 Jul 6;317(5834):116-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17615357" target="_blank"〉PubMed〈/a〉
