Bacterioplankton of the SAR11 clade are the most abundant microorganisms in marine systems,
usually representing 25% or more of the total bacterial cells in seawater worldwide. SAR11 is divided
into subclades with distinct spatiotemporal distributions (ecotypes), some of which appear to be
specific to deep water. Here we examine the...

SAR11 is an ancient and diverse clade of heterotrophic bacteria that are abundant throughout the world's oceans, where they play a major role in the ocean carbon cycle. Correlations between the phylogenetic branching order and spatiotemporal patterns in cell distributions from planktonic ocean environments indicate that SAR11 has evolved into...
Nitrogen is one of the major nutrients limiting microbial productivity in the ocean, and as a result, most marine microorganisms
have evolved systems for responding to nitrogen stress. The highly abundant alphaproteobacterium “Candidatus
Pelagibacter ubique,” a cultured member of the order Pelagibacterales (SAR11), lacks the canonical GlnB, GlnD, GlnK, and...
