Stimulation of light-induced lipid peroxidation by salts in isolated chloroplasts in the presence of carbonylcyanide m-chlorophenylhydrazone.
Effects of salts on light-induced lipid peroxidation were examined in isolated spinach chloroplasts. In the presence of carbonylcyanide m-chlorophenylhydrazone, salts stimulated lipid peroxidation, which was partially suppressed by superoxide dismutase. Salts may cause the stimulation by decreasing the negative surface charges on the thylakoid membrane, in addition to affecting electron transport.
