Abstract : Water status is the main factor affecting rice production. The submergence due to flash-floods is the key factor limiting the yield of rice that grows in lowland ecosystems. During response and adaptation to the submergence stress, many stress-related genes are induced and the levels of a variety of stress resistance-related functional proteins are accumulated. The alteration of protein synthesis or degradation is one of the fundamental metabolic processes that may influence submergence tolerance. We report here a proteomic approach to investigate the effect of submergence stress on the rice (Oryza saliva L.) proteome. Plants were stressed for 24, 48, 72 and 96 hours. Total proteins were extracted and separated by one dimensional gel electrophoresis followed by Coomassie staining.
