Abstract/Contents:"Dollar spot, caused by fungal pathogen Sclerotinia homoeocarpa, is one of the most economically important diseases of amenity turfgrasses worldwide. In spite of this, very little is known about the interactions between S. homoeocarpa and its hosts at the molecular level. In the present research, germin-like protein (GLP) family gene s were evaluated for their role in defense against S. homoeocarpa. Specific GLP genes of rice and barley have demonstrated defense roles against other phytopathogenic fungi. A growth chamber assay was conducted on three creeping bentgrass (Agrostis stolonifera L.) cultivars with varying levels of susceptibility to dollar spot. Pots of each cultivar were inoculated with either four day-old plugs of S. homoeocarpa or plugs of PDA and arranged in a 2x3 factorial within an RCBD with four replications. Tissue for RNA extraction and RT-qPCR analysis was harvested from the site of inoculation before and at 24 and 96 hours after inoculation. Results from RT-qPCR analysis indicated that all GLP genes investigated were significantly up-regulated in inoculated versus mock-inoculated plants at 96 hpi, regardless of host cultivar, but were not up-regulated at 24 hpi. Gene silencing techniques are now being employed to investigate the specific role of GLP genes in defense against S. homoeocarpa. This research will be useful for understanding molecular aspects of host defense against S. homoeocarpa and breeding for dollar spot resistance. "
