摘要：Superoxide dismutase (SOD) is one of the major classes of antioxidant enzymes, which protects thecellular and subcellular components against harmful reactive oxygen species. In maize, three types of SODsare present based on their constituent metal ions, namely Cu/Zn-SOD, Mn-SOD and Fe-SOD. We investigatedthe effect of water stress on SOD isozymes in two contrast maize genotypes, tolerant and susceptible. We foundMn-SOD and Fe-SOD with production of more transcriptomes in the tolerant genotype than susceptible.Cytosolic SOD had heightened expression levels in the tolerant genotype. The expression analyses of cytosolicSOD, Mn-SOD and Fe-SOD would be used as candidate genes for the development of drought tolerant maize.
