| Abstract/Contents: | "Waitea circinata var. circinata (Wcc) is an emerging pathogen of turfgrass in North America. It causes brown ring patch of turfgrass in golf courses and amenity areas. The population dynamics and dispersal pathway of this pathogen in the U.S. have not been well studied. In attempt to elucidate this, we isolated eight promising microsate llite markers from an enriched genomic library of Wcc. Seven of these markers were used to study the population diversity of eastern and western of U.S. populations of Wcc and the association with phenotypic characteristics. In general, the microsatellite markers so developed were highly polymorphic, with an observed hetero-zygosity of > 0.5. The eastern population was differentiated from western population but both populations showed presence of immigrant individuals across boundaries. Analysis of population structure with geography portrayed a significant clinal expansion, r2= 0.11, P = 0.01, of Wcc within a radius of about 150 km but it became more stochastic with increase in distance. No host specific clusters were observed based on a UPGMA clustering, suggesting a lack of association between host and pathogen genotypes." |
