 A) Pairwise comparisons of the minor pilins gene cluster between strains of Xanthomonas translucens (i.e. X.t. pv. translucens DSM 18974, pv. cerealis CFBP 2541, pv. phlei LMG 730, pv. phleipratensis LMG 843, pv. arrhenatheri LMG 727, pv. poae LMG 728, and pv. graminis LMG 726, Xtg2, Xtg9, Xtg29 and NCPPB 3709). Colors denote similar genes. The pilY1 gene is represented in different colours in pv. graminis strains compared to other strains as its sequence was too divergent and they were considered as different genes by the software. Numbers below strain names refer to the position of the gene cluster in this genome sequence. B) Alignment of the amino acid sequences of pilW. Only the pv. graminis strain LMG 726 is represented as the sequences were identical in all five pv. graminis strains. Colours represent amino acids that were conserved among at least six out of seven strains (red) or amino acids with similar properties that were found in at least six out of seven strains (green). Highlighted in blue is the class III signal peptidase cleavage site that is characteristic to pilins
