Research

My work focuses on genome-wide association studies (GWAS) analysis on mesophyll conductance (gm) and stomatal condutances (gs) using 200 rice natural populations grown under paddy and upland field conditions to identify potential QTLs and target genes responsible for desirable drought tolerance traits. To isolate effects of gs, normalization of sampled δ13C will be determined to further perform genetic differences of gm in the given natural population. In my preliminary test, results showed long-term discordant open of stoma responded to occasional shade due to overlap effects of leaves resulted in foliar over evaporation and low water use efficiency especially in the field cases. By this point, 15 min low light (100μmol m-2s-1) induced altering of gs and following full recovery of light (1200μmol m-2s-1) will be used to reveal whether diversity pattern of gs and limitation of gs to PN occur in our study. Genotype-specific decrease ratio of gs will be considered for exploitation of some QTLs and potential gene.
