Uittreksel

Puccinia horiana is one of the most important diseases in chrysanthemum production. Phenotypic characterization of a worldwide collection of isolates via controlled inoculation experiments on a set of differential cultivars revealed the presence of pathotypes and at least seven avirulence genes. Genotypic characterization involved the development and application of 25 differential SNP markers. Genotypic diversity was strongly related to geographic origin, while evidence of sporadic large distance international spread as well as recombination were also observed. Although pathotype-based diversity was larger than SNP-based diversity, the most virulent pathotypes could be identified based on their SNP profile. This allows the use of the genotyping technique in quarantine monitoring.
