Genomes
Prochlorococcus
Prochlorococcus is a marine cyanobacterium that numerically dominates the mid-latitude oceans, and is the smallest known oxygenic phototroph. All isolates described thus far can be assigned to either a tightly clustered high-light (HL) adapted clade, or a more divergent low-light (LL) adapted group. We have obtained sequences of twelve genomes (links below), ranging in size from 1.6 to 2.6 Mbp, representing diverse lineages, both LL- and HL-adapted, spanning the complete rRNA diversity (97 to 99.93% similarity) of cultured representatives of this group. Our analyses of these data informs our understanding of how adaptation occurs in the oceans along gradients of light, nutrients, and other environmental factors, providing essential biological context for interpreting rapidly expanding metagenomic datasets.
