Abstract

Silicon (Si) is a micronutrient. Its amount has been found to vary from plant to plant. Si in rice has been shown to provide tolerance against various biotic and abiotic stresses, especially rice blast and drought. Although rice contains higher amount of Si compared to other crops but the concentration varies between different species. In our own study we observed variation in the Si content among various genotypes of rice. A positive correlation between Si content in various plant parts of aerobically grown rice and the yield traits was observed, indicating the role of Si in giving tolerance against water stress. The genes responsible for Si accumulation in rice are known. However, the proteins induced due to Si application are to be mined. Here we propose a strategy based on genomics (molecular breeding) and proteomics approaches for effective utilization/incorporation of Si in commonly cultivated rice varieties to enhance its tolerance to various stresses.
