Analysis of eggNOG phyletic patterns of proteins encoded in various bacterial genomes. The plot shows the position of individual genomes on the plane of the first two principal components. Major bacterial groups are indicated. A. All 59 bacteria (Supplementary Table 1 [see Additional file 1]). B. Cyanobacteria and Chlamydia removed from the dataset. C. Self-organizing map of the genome content.
