The marine cyanobacterium Prochlorococcus is the numerically dominant
photosynthetic organism in the oligotrophic oceans, and a model system in marine
microbial ecology. Here we report 27 new whole genome sequences (2 complete and
closed; 25 of draft quality) of cultured isolates, representing five major
phylogenetic clades of Prochlorococcus. The sequenced strains were isolated from
diverse regions of the oceans, facilitating studies of the drivers of microbial
diversity – both in the lab and in the field. To improve the utility of these
genomes for comparative genomics, we also define pre-computed clusters of
orthologous groups of proteins (COGs), indicating how genes are distributed
among these and other publicly available Prochlorococcus genomes. These data
represent a significant expansion of Prochlorococcus reference genomes that are
useful for numerous applications in microbial ecology, evolution and
