Genetic Diversity Analysis Reveals High Heterozygosity, Low Clonality, and Distinct Populations in <i>Peronospora belbahrii</i>
isolates collected during 2018-2024 from Israel, Italy, Hawaii, Florida, Kansas, and the US Northeast. Genetic diversity statistics indicate a highly heterozygous, largely non-clonal population structure in both the USA and Israel. These two populations appear to be at least partially genetically distinct and indicate differentiation along geographic lines. Significant genetic differences were also detected between race 0 and race 1, though a distinct set of classifying markers was not found.
