| Abstract: | In order to determine the influences of H2O2 and ABA on antioxidant defense system induced by the combination of drought and heat stress in maize(Zea mays L.) seedlings leaves,the ABA-deficient maize vp5 mutant and its wild-type Vp5 were used in these studies.After pretreatment with H2O2 scavenger KI,ABA inhibitor tungstate(T),the expression of four antioxidant defense gene SOD4,GR1,CAT1 and cAPX were measured.The results were as follows:(1) compared with control,drought,heat and their combination stress al... |
