Association mapping of drought tolerance genes
Association analysis through linkage disequilibrium is a useful new tool for the dissection of complex traits and identification of superior alleles at genes identified. Presented here are the results in the search for DNA polymorphisms associated with drought tolerance, a highly quantitative trait in maize, using the candidate gene approach. The drought association mapping test characterized 3...
متن کاملGenetic basis of drought resistance at reproductive stage in rice: separation of drought tolerance from drought avoidance.
Drought tolerance (DT) and drought avoidance (DA) are two major mechanisms in drought resistance of higher plants. In this study, the genetic bases of DT and DA at reproductive stage in rice were analyzed using a recombinant inbred line population from a cross between an indica lowland and a tropical japonica upland cultivar. The plants were grown individually in PVC pipes and two cycles of dro...
متن کاملDifferentially expressed genes between drought-tolerant and drought-sensitive barley genotypes in response to drought stress during the reproductive stage
Drought tolerance is a key trait for increasing and stabilizing barley productivity in dry areas worldwide. Identification of the genes responsible for drought tolerance in barley (Hordeum vulgare L.) will facilitate understanding of the molecular mechanisms of drought tolerance, and also facilitate the genetic improvement of barley through marker-assisted selection or gene transformation. To m...
متن کاملEvaluation of Drought Tolerance in Barley Genotypes (Hordeum vulgare L.) using Drought Tolerance Indices
Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...
متن کاملQuantitative trait loci associated with drought tolerance at reproductive stage in rice.
Drought is a major constraint to rice (Oryza sativa) yield and its stability in rainfed and poorly irrigated environments. Identifying genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and development of more drought tolerant cultivars. Quantitative trait loci (QTL) for grain yield and its co...
