The SAR11 clade consists of very small, heterotrophic marine α-proteobacteria that are found throughout the oceans, where they account for about 25% of all microbial cells. Pelagibacter ubique, the first cultured member of this clade, has the smallest genome and encodes the smallest number of predicted open reading frames known for a free-living microorganism. In contrast to parasitic bacteria and archaea with small genomes, P. ubique has complete biosynthetic pathways for all 20 amino acids…

The genome sequence of a marine bacterium is discussed in this issue of PNAS with a prominent example being Pelagibacter, the cultured representative of the SAR11 clade.
The α-proteobacteria: the Darwin finches of the bacterial world
- Biology, Environmental ScienceBiology Letters

By physically separating genes for information processing from genes involved in interactions with the surrounding environment, the rate of evolutionary change can be substantially enhanced for genes underlying adaptation to new growth habitats, possibly explaining the ecological success of the α-proteo-bacterial subdivision.
The reduced genomes of Parcubacteria (OD1) contain signatures of a symbiotic lifestyle

Pan-genome analysis indicates a broad genotypic diversity and perhaps a highly fluid gene complement, indicating historical adaptation to a wide range of growth environments and a high degree of specialization.
Whole genome analysis of the marine Bacteroidetes'Gramella forsetii' reveals adaptations to degradation of polymeric organic matter.
- Biology, Environmental ScienceEnvironmental microbiology
- 2006
Functional analysis of the predicted proteome disclosed several traits which in joint consideration suggest a clear adaptation of this marine Bacteroidetes representative to the degradation of high molecular weight organic matter, such as a substantial suite of genes encoding hydrolytic enzymes, a predicted preference for polymeric carbon sources and a distinct capability for surface adhesion.

Genome organisation of the marine Roseobacter clade member Marinovum algicola
- BiologyArchives of Microbiology

The genome structure and extrachromosomal DNA content of four strains of the roseobacter species Marinovumalgicola are analysed by pulsed-field gel electrophoresis, indicating that recombination and conjugative gene transfer are dominant mechanisms for microevolution within the Roseobacter clade.
Genomic and functional adaptation in surface ocean planktonic prokaryotes
- Environmental Science, BiologyNature

The sequencing of 137 diverse marine isolates collected from around the world is analysed to gain insights into the ecology of the surface ocean prokaryotic picoplankton and suggests that one method used to avoid predation by viruses and/or bacterivores is by means of slow growth and the maintenance of low biomass.
Ecological Genomics of Marine Roseobacters
- BiologyApplied and Environmental Microbiology
- 2007
Comparative genome sequence analysis of three cultured Roseobacter representatives suggests that cellular requirements for nitrogen are largely provided by regenerated ammonium and organic compounds, while typical sources of carbon include amino acids, glyoxylate, and aromatic metabolites.

The absence of an intron in the gene for tRNA(Leu)(UAA), which otherwise is widespread among cyanobacteria, and the additional finding that the ribosomal operon exists as a single copy suggest that the deletion of non-essential sequences played a major role in the evolution of P. marinus.

The results clearly indicate that genome reduction has been accompanied by an increased rate of protein evolution in P. marinus SS120 that is even more pronounced than previously reported, and that MED4 and SS120 have lost several DNA-repair genes.
