Production of hydrogen peroxide and hydroxyl radical in potato tuber during the necrotrophic phase of hemibiotrophic pathogen Phytophthora infestans infection
Original language description
In this study, evidence is provided on the formation of hydrogen peroxide (H2O2) and hydroxyl radical (HO?) in the potato tuber during the necrotrophic phase of the hemibiotrophic pathogen Phytophthora infestans infection. Using 3,3-diaminobenzidine tetrahydrochloride (DAB) imaging technique, the formation of H2O2 was demonstrated in Phytophthora infestans-infected potato tuber. For the first time, HO? formation was demonstrated in Phytophthora infestans-infected potato tuber using electron paramagneticresonance (EPR) spectroscopy. An enhancement in spontaneous ultra-weak photon emission indicated the extent of lipid peroxidation in the Phytophthora infestans-infected potato tuber. The data presented in this study reveal that the formation of H2O2 andHO? in the Phytophthora infestans-infected potato tuber is associated with lipid peroxidation. It is proposed here that the ultra-weak photon emission can be used as a non-invasive indicator of the oxidative processes in the quality cont
