Relationship among the different CRISPR genotypes of E. amylovora analyzed in this study in terms of spacer losses (Δ) or duplications (^). Six main clusters with discrete geographical distribution, all originating from archetypal genotype (A, a, α), could be identified (left). Deletions of spacer 1029 (Δ1029) cause an apparent reversion from an A-derived (blue boxes) to a D-derived (green boxes) or a null genotype, if analyzed with the PCR approach proposed by Kurz et al. (2021). Putative intermediate genotypes not found in this work are represented by dashed boxes. Genotypes that could not be directly assigned to any group, as well as their modification with respect to archetypal genotype (A, a, α) are shown in a separate box (right)
