| Abstract/Contents: | "Clarireedia spp. (formerly Sclerotinia homoeocarpa F.T. Bennett) is the causal agent of dollar spot disease on turf grasses of golf courses and is one of the most economically important turfgrass pathogens in North America. The most effective strategy for dollar spot control is repeated application of multiple classes of fungicides. However, it is well known that repeated fungicide application influences the development of fungicide resistance. Succinate dehydrogenase inhibitors (SDHI) are a widely used fungicide class for the management of dollar spot as well as many other plant pathogenic fungal diseases impacting a variety of crops. Our lab has identified 6 succinate dehydrogenase (SDH) subunit mutations conferring resistance to SDHIs in Clarireedia spp. Recent research has indicated that different mutations confer differential sensitivity profiles for each SDHI active ingredient. However, not much is known about the protein conformational changes caused by each SDH mutation and how those structural changes contribute to this variable sensitivity. Therefore, the objectives of this research are to 1) characterize the structure of 6 mutated SDH proteins conferring SDHI resistance in Clarireedia spp. 2) utilize this structural characterization to support the chemical industry in screening and designing novel fungicides for control of each mutation and 3) develop management strategies for resistant populations of plant pathogenic fungi." |
