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...

Bacteria in the class Alphaproteobacteria have a wide variety of lifestyles and physiologies. They include pathogens
of humans and livestock, agriculturally valuable strains, and several highly abundant marine groups. The ancestor of
mitochondria also originated in this clade. Despite significant effort to investigate the phylogeny of the
Alphaproteobacteria with a...

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...
