FIG 1.

Amino acid sequence variation between the genomes of P. aeruginosa strains PA14 (ST253) and 60P57PA (ST235) sorted by functional category. The reads of strain 60P57PA (ST235) were mapped to the PA14 reference strain (ST235), and 8,150 amino acid differences were detected and functional categories were assigned according to PA14 annotation. As a comparison, the frequency was compared to the distribution in the PAO1 reference genome by dividing the detected functional classes by the number of occurrences of the respective class within the PAO1 reference genome. The gray line symbolizes a theoretical even distribution between the number of amino acid exchanges in ST235 compared to that in ST253 and the occurrence of functional classes in PAO1. EPS, exopolysaccharide.
