Independent genome reduction and phylogenetic reclassification of the oceanic SAR11 clade.

Molecular biology and evolution - 1 Feb 2012

Viklund Johan, Ettema Thijs J G, Andersson Siv G E

Abstract excerpt

The SAR11 clade, here represented by Candidatus Pelagibacter ubique, is the most successful group of bacteria in the upper surface waters of the oceans. In contrast to previous studies that have associated the 1.3 Mb genome of Ca. Pelagibacter ubique with the less than 1.5 Mb genomes of the Rickettsiales, our phylogenetic analysis suggests that Ca. Pelagibacter ubique is most closely related to soil and aquatic...
