| Abstract/Contents: | "Gray leaf spot caused by Pyricularia grisea, is a new disease to turfgrass in the western [US.] A total of 73 isolates of P. grisea from perennial ryegrass (Lolium perenne) and kikuyugrass (Pennisetum clandestinum) from 14 different locations in California and Nevada were analyzed using amplified fragment length polymorphisms (AFLP) and mating type to determine population genetic structure. Preliminary AFLP analysis using one primer combination detected 13 polymorphisms. Populations from both hosts had similar genotypes, indicating no host specificity. PCR amplification with selective primers for mating type indicate that P. grisea populations from perennial ryegrass were exclusively Mat1-2 while both Mat1-1 and Mat1-2 were present in kikuyugrass isolates. However, isolates from both hosts were genotypically diverse which was not expected since the disease is new to California on perennial ryegrass and kikuyugrass. This suggests that these fungi may have been present in the west and that cultural practices or environmental conditions may have recently allowed them to become problematic on these turfgrasses. Alternatively, recent immigration from diverse populations may have occured. These hypotheses will need to be tested by comparing western isolates to established populations in the eastern US." |
