- Abstract:
- To discuss the function mechanism of GLP7 gene in antioxidation stress and its biological function,GLP7 transgenic lines of soybean and its acceptor cultivar Kenfeng 16(WT)were used to measure activities of superoxide dismutase(SOD),catalase(CAT),chlorophyll and(MDA)contents under oxidant methyl viologen(MV)stress.The results showed that,compared with nontransgenic soybeans,transgenic soybeans reduced MDA content,increased total chlorophyll content,SOD and CAT activity in MV stress treatment.These results indicated that the over expression of GLP7could effectively enhance the activities of antioxidant ability and reduce the damage on the soybean seedlings under oxidative stress.
