| Abstract/Contents: | "Anthracnose disease caused by Colletotrichum cereale is one of the most destructive maladies of golf course turfgrasses. The fungus has also been identified from numerous natural grasses and cereal crops, although disease symptoms are rarely observed. In this research we investigated the role of ecosystem (turf, cereal crop or prairie) and the impact of natural grass/cereal strains on turf anthracnose. Genotypic signatures from 4 nuclear genes and 22 microsatellite markers were used to analyze an extensive sample from the North America, Europe and Japan. Eleven major populations were identified, structured according to ecosystem type: three turfgrass groups, seven prairie/cereal groups and one diverse group comprised of both turf and non-turf isolates. The turfgrass populations were further defined according to host species: two groups almost entirely limited to Poa annua, the third to Agrostis stolonifera. In cereal/prairie populations, a similar pattern was observed, dividing wheat and oat isolated into discrete groups. Extreme differentiation between locally-adapted populations suggests asymptomatic grasses are unlikely reservoirs of infectious disease particles that could serve to fuel disease in turf. But gene flow between the generalist founder population and specialized genotypes provides a mechanism for genetic exchange between otherwise isolated populations. These findings demonstrate that while disease occurrence and spread is currently localized to the turfgrass environment, introgression between C. cereale ecotypes can lead to the expansion of anthracnose disease into new ecosystems." |
