| Abstract/Contents: | "Plant drought tolerance is a complex trait that is controlled by multiple genes. Candidate gene association mapping provides a powerful tool for dissection of complex traits. We conducted candidate gene-association mapping of drought tolerance traits in 192 diverse perennial ryegrass (Lolium perenne L.) accessions from 43 countries. A total of 346 single nucleotide polymorphisms were identified from genes involved in antioxidant metabolism, dehydration, and water movement across membrane and signal transduction. Significant associations were identified between a putative LpLEA3 encoding late embryogenesis abundant group 3 protein and a putative LpFeSOD encoding iron superoxide dismutase and leaf water content, as well as between a putative LpCyt Cu-ZnSOD encoding cytosolic copper-zinc superoxide dismutase and chlorophyll fluorescence under drought conditions. These results indicate that allelic variation in these genes may affect whole-plant response to drought stress in perennial ryegrass." |
