| Abstract/Contents: | "Little is known about the geographic distribution and genetic diversity of the fungi that cause spring dead spot of bermudagrass (Cynodon dactylon (L.) Pers.). We systematically sampled individual spring dead spot patches on three golf course fairways (ca. 60 samples/fairway) from two golf courses in northeastern Oklahoma and one course in southeastern Kansas. Ophiosphaerella herpotricha was isolated from 100%, 95%, and 90% of the samples collected from the two Oklahoma and one Kansas courses, respectively. O. korrae and O. narmari were isolated from <5% of the samples collected at one Oklahoma course whereas O. korrae occured in 10% of the Kansas golf course samples. This is the first report of O. korrae on bermudagrass in Kansas. DNA extracted from O. herpotricha isolates was amplified with oligonucleotide primers derived from the multicopy probe pOH29. Although some isolates collected from adjacent patches appeared to be clonal, polymorphic DNA banding patterns among most isolates collected in the same location suggests a more diversified genotypic distribution." |
