| Abstract/Contents: | "The fungal genus Colletotrichum contains several species that infect monocot hosts in both cultivated and natural grass communities. In monocultured agroecosystems like those found on golf course greens, these fungi are often found as destructive pathogens, capable of inducing significant disease in the host plant. In contrast, our recent sampling of Colletotrichum in a natural tallgrass prairie ecosystem suggests that populations of this fungus living in diverse grass communities maintain a non-pathogenic lifestyle, with their presence never correlated with substantial disease. In turfgrass stands, either one of two distinct Colletotrichum lineages may be present, but in natural grassland environment, our preliminary data reveals the presence of only a single lineage. Interestingly, based upon transposon distribution data and RFLP patterns, it appears that the prairie grasslands may actually represent a hybrid zone between the genotypes of distinct Colletotrichum phylogenetic species, while the corresponding turfgrass populations are generally of non-hybrid origin. We are currently developing a set of microsatellite markers to generate the hypervariable genetic data needed to explore how variation is distributed spatially within Colletotrichum populations inhabiting these different ecosystems. Importantly, this comparative approach will allow us to detect historical events of interest such as population fragmentations, range expansions, and colonization in the Colletotrichum species that inhabit Pooideae grasses. Investigating the differences between the Colletotrichum populations from natural prairie grasslands and the inhabitants of golf course greens may help us to identify the forces that have shaped the recent evolution of this fungus into an aggressive pathogen of cultivated amenity turfgrasses." |
