Trends in genome/proteome evolution of Prochlorococcus, suggesting a stepwise diversification of the ecotypes. The model is based on the 16S rRNA phylogeny of the 12 strains, inferred from a bootstrap consensus tree (500 replicates) generated using the Minimum Evolution method (CNI algorithm), with the software MEGA (version 4).
