Phenomics Of Moisture Deficit and Low Temperature Stress Tolerance in Rice

The major challenges to crop productivity are the abiotic stresses such as drought, cold and heat. Drought is a problem in 45 % of the world geographical area, where 38 % of the world human population lives. Cold stress prevents the expression of full genetic potential of plants owing to its direct inhibition of metabolic reactions and, indirectly, through cold-induced osmotic (chilling-induced inhibition of water uptake and freezing-induced cellular dehydration), oxidative and other stresses. Genetic tolerance to these stresses shows complex inheritance and thus is difficult to address using conventional approaches. Recent developments in the area of genomics provide immense opportunities for dissecting the stress tolerance phenome through forward and reverse genetic approaches. The nature of the phenome defines agricultural productivity and the economic worth of the produce. Enhancement of agricultural productivity therefore necessitates a far greater understanding of the phenome under varying environment. Hence there is the urgent need for precision phenomics in Indian agriculture. Phenomics facility proposed to be created in the project will be used for high throughput and accurate phenotyping of germplasm lines as well as mutants and transgenics, and thus will enhance the pace of genetic improvement for drought, heat and cold tolerance in rice. It would employ many powerful modern tools and techniques including the imaging technologies like fluorescence, bioluminescence, thermal imaging (both NIR, FIR), and hyperspectral reflectance imaging to understand how the rice crop cope up, react and withstand or tolerate stresses.
