Fig. 7From: Tracking the dissemination of Erwinia amylovora in the Eurasian continent using a PCR targeted on the duplication of a single CRISPR spacerGeographical distribution and timeline of the appearance of A- and D-derived genotypes in Spain in the timeframe 1995–2006. Striped stars indicate the presence of two genotypes in one geographical location. The null PCR genotype (labelled as 0 in the timeline) is indicated in red. Wherever available results of PFGE characterization on the same isolates were added for comparison (Jock et al. 2002; Donat et al. 2007)Back to article page
