Flow chart of the phylogenetic tree of 30 gamma-proteobacterial genomes reconstructed on the basis of conserved OG pairs. The left panel shows a phylogenetic UPGMA tree for the 30 gamma-proteobacterial genomes based on the number of their shared OG pairs. Each branch is labeled by the species name and the total number of OG pairs in the genome in square brackets. The right upper panel shows all the conserved OG pairs in the genome of interest when the species name is clicked on the tree, e.g. Escherichia coli K12. The right lower panel describes the information about one OG pair (e.g. 83333_44) and the list of its orthologous OG pairs within the subtree-specific genomes.
