Figure 6From: Distinct, ecotype-specific genome and proteome signatures in the marine cyanobacteria ProchlorococcusTrends 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).Back to article page
