Technical Abstract: The goal of this project is to identify critical genes for the control of sheath blight disease. To this end, an in vitro method to examine interactions of rice with the rice sheath blight pathogen Rhizocotnia solani was developed. The initial analysis of R. solani isolates from the Arkansas rice fields revealed three classes of most virulent, moderately virulent and weakly virulent isolates. Differential responses of rice cultivar leaves toward these pathogen isolates were detected using a novel detached leaf method. Characterized R. solani isolates are being used to identify differentially expressed genes.
