TL;DR: The results illustrate major differences between crenarchaea and euryarchaea, especially for their DNA replication mechanism and cell cycle processes and their translational apparatus.
Journal ArticleDOI
The genome of Aeromonas salmonicida subsp. salmonicida A449: insights into the evolution of a fish pathogen
Michael Reith,Rama K. Singh,Bruce A. Curtis,Bruce A. Curtis,Jessica M. Boyd,Anne B. Bouevitch,Jennifer Kimball,Janet Munholland,Colleen A. Murphy,Darren Sarty,Jason Williams,John H. E. Nash,Stewart C. Johnson,Laura L. Brown +13 more
TL;DR: The genome sequence of A. salmonicida was determined to provide a better understanding of the virulence factors used by this pathogen to infect fish and provide insights into the mechanisms used by the bacterium for infection and avoidance of host defence systems.
Journal ArticleDOI
A molecular phylogeny of the marine red algae (Rhodophyta) based on the nuclear small-subunit rRNA gene
TL;DR: Tests under maximum-likelihood and parsimony of alternative phylogenies based on structure and chemistry refuted suggestions that Acrochaetiales is the most primitive florideophyte order and that Gelidiales and Hildenbrandiales are sister groups.
Journal ArticleDOI
Degree of selective constraint as an explanation of the different rates of evolution of gender-specific mitochondrial DNA lineages in the mussel mytilus.
Donald T. Stewart,Ellen R. Kenchington,Ellen R. Kenchington,Rama K. Singh,Eleftherios Zouros,Eleftherios Zouros +5 more
TL;DR: In this paper, the authors show that the M lineage experiences relatively relaxed selection in comparison to the F lineage and suggest that these differences in selection pressure are a consequence of doubly uniparental mitochondrial DNA transmission in Mytilus.
Journal ArticleDOI
Organizational characteristics and information content of an archaeal genome: 156 kb of sequence from Sulfolobus solfataricus P2.
Christoph Wilhelm Sensen,Hans-Peter Klenk,Rama K. Singh,G. Allard,C. C.‐Y. Chan,Q. Y. Liu,S. L. Penny,F. Young,Margret E. Schenk,Terry Gaasterland,Terry Gaasterland,Terry Gaasterland,W. F. Doolittle,W. F. Doolittle,Mark A. Ragan,Mark A. Ragan,Robert L. Charlebois,Robert L. Charlebois +17 more
TL;DR: A novel termination motif is proposed to account for 15 additional terminations in the 3Mbp genome of the thermoacidophilic archaebacterium Sulfolobus solfataricus P2, indicating a process of initial mRNA‐ribosome contact unlike that of most eubacterial genes.
