Interpretive Summary:

Technical Abstract: Sclerotium oryzae is the causal agent of stem rot disease in rice, one of the most important rice diseases in California. Resistance to stem rot, derived from a wild relative of rice called Oryza rufipogon, was identified over twenty years ago and has been crossed into various California breeding lines. However, no varieties with significant levels of resistance have been released and the genetic and molecular basis of resistance remains largely unknown. With regard to the pathogen, extensive characterization of the biology of S. oryzae has been reported including the identification of different levels of virulence among isolates, but no information exists at the molecular genetic level of characterization. We report here on our progress in developing tools and resources to identify the molecular genetic basis for resistance to stem rot and for virulence in the stem rot pathogen.
