Comparison of phylogenetic analyses based on CRISPR data (a) and AFLP data (b) for 56 strains of X. citri pv. citri. AFLP data were taken from previous work [17]. AFLP and CRISPR data were converted into a binary array according to the presence or absence of each marker (except for the 14 unique spacers of strain CFBP 2911) and clustering was inferred using the UPGMA method. Different colors of characters indicate different clusters and the same strains are represented by the same color in both panels
