Technical Abstract: Sustainable crop production in the U.S., as well as in other areas of the world, will rely upon the crop’s ability to yield under progressively limiting conditions: marginal soils, decreased water availability, and oftentimes critical temperature stress. Enhanced understanding of the physiological and molecular adaptive responses in crop plants, along with identification of tolerant germplasm, will make the greatest difference in our ability to develop tolerant cultivars. Specific hypotheses for this project are: 1) existing peanut germplasm pools represent an untapped genetic resource and contain multiple sources of abiotic stress tolerance; 2) small RNAs play a key role in the regulation of the abiotic stress response in peanut; and 3) although tolerance to abiotic stress tolerance is complex and a quantitative, it can be understood by measuring the coordinated molecular, cellular, and physiological responses in tolerant and susceptible genotypes, along with traditional yield-based analyses.
