California State University, Fresno Department of Biology, Presents “Understanding the Molecular Mechanism for Disease Resistance and Improved Shelf Life Using Rice as a Model System” Dr. Moytri Roy-Chowdhury Post-doctoral Researcher Texas A&M University at USDA-ARS Crop Diseases, Pests, and Genetics Unit, Parlier, CA Plant disease management has always been one of the main objectives of any crop improvement program. Plant disease resistance (R) genes have the ability to detect a pathogen attack and facilitate a counter attack against the pathogen. This concept triggered the marker assisted selection (MAS) strategy used in breeding programs for improved resistance. MAS, is based on DNA markers closely linked to a R gene that confers resistance to a particular race of the pathogen, and can be used to screen seeds or seedlings under laboratory conditions, which is much faster than traditional pathogenicity assays where accurate selection can only be made during the later stages of plant growth. Accurate identification of a particular R gene in diverse elite germplasm using DNA markers is an essential step. This ensures the accuracy of R gene utilization in MAS for different rice breeding programs. Shelf life is another important factor when it comes to crop management. The marketability of any perishable food is dependent on the extended shelf life. Keeping these two concerns in mind this presentation focuses on using molecular methods to identify germplasm using SSR markers closely linked to R genes and to determine disease reactions of these germplasm to differential pathogen races. It also focuses on strategies on improving the shelf life by understanding and manipulating the enzymatic pathway involved in the process. The presentation uses rice as the model system.
