Title: Response of Polyphenol Oxidase Activity in Glycine soja Inoculated with Phytophthora sojae
Abstract: Phytophthora root and stem rot of soybean(Phytophthora sojae)has become a serious damage to soybean production in China,especially in main soybean production region,Heilongjiang province.Polyphenol oxidase(PPO)is an important enzyme related to disease resistance in plants.However,there are few reports about response of PPO activity in wild soybeans infected with Phytophthora sojae.A total of eight wild soybeans including four resistant and four susceptible ones were inoculated with zoospores of P.sojae race 1 as treatment and those inoculated with water as control.The results showed that PPO activity in roots and leaves of resistant wild soybeans increased compared with those of control at the whole stage of pathogenetic process,and that in stems also increased at most stages of pathogenetic process.However,the PPO activity in roots and leaves of the four susceptible wild soybeans decreased at most stages of pathogenetic process.The results could lay theoretical basis on physiological and biochemical mechanism for disclosing wild soybean's resistance to P.sojae.
