Comparative genomics of host-specialized populations of Corynespora cassiicola causing target spot epidemics in the southeastern United States.

ABSTRACT: Numerous plant-pathogenic fungi secrete necrotrophic effectors (syn. host-selective toxins) that are important determinants of pathogenicity and virulence in species that have a necrotrophic lifestyle. Corynespora cassiicola is a necrotrophic fungus causing emerging target spot epidemics in the southeastern United States (US). Previous studies revealed that populations of C. cassiicola from cotton, soybean, and tomato are clonal, host specialized and genetically distinct. Additionally, cassiicolin - the necrotrophic effector identified in some C. cassiicola isolates - is an important toxin for virulence on rubber. It is encoded by seven Cas gene variants. Our goal was to conduct comparative genomic analyses to identify variation among putative necrotrophic effec
