| Abstract/Contents: | "Grasses cultivated as turf make up a major component of the North American landscape. Beginning in the 1990s, anthracnose caused by the fungus Colletotrichum cereale emerged as one of the most destructive diseases of golf course turf, with its incidence, severity and geographic range greatly expanded. The sudden emergence of this disease on greens is puzzling. Was the spread of turfgrass anthracnose due to the introduction of novel genotypes or did recent environmental/cultural change provide an opportunity for adaptation by endemic genotypes? Here we present an investigation of the origin of North American turfgrass anthracnose epidemics. Genotypic signatures from four nuclear genes were analyzed from an extensive sample of pathogenic turfgrass isolates and non-pathogenic prairie/cereal-derived groups and one diverse group compromised of both turf and non-turf isolates. High levels of genetic diversity, ecosystem specificity, turf host specificity and recombining populations provided evidence of endemic populations assuming a pathogenic lifestyle in response to changing environmental conditions on golf courses. Endemism is also consistent with the observation that North American turfgrass populations and genotypes of C. cereale are more closely related to one another than to any internation or non-turf isolates." |
