Abstract/Contents: | "Leptosphaeria korrae is a homothallic Ascomycota that causes necrotic ring spot in turfgrass, principally Kentucky bluegrass. It is not known if this disease is spread primarily by mycelia or ascospores. To evaluate the role of ascospores in dissemination, it first needed to be determined if progeny from self fertilization could be differentiated since polymorphisms are expected to be limited in isolates of such an organism. Eight sibling single spore progeny were examined for the presence of DNA polymorphisms using random amplified polymorphic DNA markers. No polymorphisms were observed with any of the five primers tested. Due to this lack of polymorphism, the study was expanded to look for differences between isolates on a regional level. Isolates of L. korrae from British Columbia, Ontario, Quebec and the state of Washington were then examined using the same primers. Two of the primers revealed polymorphisms within and between these regions." |
