Figure 5

Principal Component Analysis of six R. solanacearum genomes, performed from a two dimensional matrix, combining genomes and metabolic pathways. Individual points represent genomes, and colored vectors symbolize completion of some pathways (number of reaction for pathway x in a given organism/total number of reactions in the same pathway x defined in the MetaCyc database) in the data (see method section). Pathways with similar completions (vectors with similar orientation) have been clustered and drawn in a same color. Thus, genomes can be associated with their representative and characteristic groups of metabolic pathways (i.e. vectors pointing in their direction). The corresponding pathway functions are listed in Suppl.Table S4.A.
