| Abstract/Contents: | "Rust is a common disease of cultivated turfgrass that can result in extensive damage or even plant death in heavily infested areas. Current control methods rely on improving turf vigor and planting resistant cultivars. Over the past six years, turfgrass breeders have observed a shift in susceptibility among certain Kentucky bluegrass (Poa pratensis L.) cultivars, particularly the 'Midnight' types. Once highly resistant to rust, these cultivars now experience a greater incidence of disease. It has been proposed that newly emerging fungal races or species may be responsible for this recent upsurge in turfgrass rust susceptibility, but the genetic information required to test this prediction is lacking. In this study, we are developing molecular methods to evaluate the species and populations that contribute to rust diseases in turfgrass hosts. To date, 114 rust infested samples have been colected from eighteen states and four countries from Kentucky bluegrass and ten additional warm- and cool-season grass hosts in the family Poaceae. Using rust spores that have been directly harvested from infested host tissue, a reliable protocol for rust DNA extraction has been developed. Initial broad screening of the rust samples through phylogenetic analysis of sequence data from ribosomal internal transcribed spacer region (ITS) is currently underway. The data generated through these investigations will be used as a foundation for the targeted development of species and race specific molecular markers that can be used by pathologists and breeders for rapid detection and identification of turf rust pathogens from the field in real-time." |
