Fig. 2

Spoligotypes of 56 X. citri pv. citri strains. CRISPR arrays are oriented with the leader-proximal spacers on the left side. Identical spacers within the same block are vertically aligned. Detected CRISPR spacers are represented by deep blue boxes, with the identifier of spacers indicated by numbers in the first row. White boxes indicate the absence of the corresponding spacer. Orange boxes indicate the presence of IS elements and the light blue box indicates a variant of spacer Xcc_18 with a deletion of 4 bp due to the IS element insertion. 14 unique spacers are shown as red box for strain CFBP 2911. Spoligotype 2* is identical to spoligogtype 2, but contains an IS element between spacers Xcc_20 and Xcc_21
