Abstract/Contents: | "Dollar spot disease of turfgrass, caused by the fungus Sclerotinia homoeocarpa, is the most important turfgrass disease occurring world-wide on all cool and warm season turfgrass species. The ribosomal DNA (rDNA) sequences were obtained from twenty-six isolates collected from Floridian warm season turfgrass species including bermudagrass (Cynodon dactylon (L.) Pers.), seashore paspalum (Paspalum vaginatum Sw.), St. Augustinegrass (Stenotaphrum secundatum (Walter) Kuntze) and zoysiagrass (Zoysia japonica Steud.) and from the Floridian cool season turfgrasses, rough bluegrass (Poa trivialis L.) and creeping bentgrass (Agrostis palustris Huds). Isolates were collected from 26 distinct golf courses and other turfgrass swards in 12 Florida counties between 2004 and 2009. These data plus 14 other S. homoeocarpa rDNA sequences from GenBank were subjected to phylogenetic analysis using the neighborg-joining method and choosing Sclerotinia sclerotiorum (Lib.) De Bary and Poculum henningsianum (Plottn.) T. Schumach. as outgroups. Phylogenetic reconstructions based on sequences of internal transcribed spacer 1 (ITS1) and internal transcribed spacer 2 (ITS2) indicated that twenty out of twenty-six Floridian isolates clustered in a group that represents a newly identified biotype of S. homoeocarpa. Further characterization of this Floridian biotype is in progress." |
