Acidovorax citrulli (Acc), the causal agent of a bacterial seedling blight and fruit blotch, effects as a serious threat to some cucurbit plant species, including watermelon, melon, cucumber, pumpkin and gourds. Till now, the bacterium was characterized on the basis of genetic studies with the 16S rDNA, DNA/DNA assays and AFLP analysis, and phenotypic data. Profound knowledge on pathogen diversity is necessary for efficiently disease management and tracking of the pathogen dissemination. In this study, we have compared genetic differentiation between Acc isolates collected from Turkey and USA by using selected ISSR primers producing high polymorphic fragments. The results showed that genetically characterized Acc isolates of Turkey and USA show genotype flow and similarity. Thesemarkers can be selected for analyzing of genetic diversity and tracking of population structure of this pathogen on different hosts.
