title: Catalases CAT1 and CAT3 are not key enzymes in alleviating gamma irradiation-induced DNA damage, H2O2 accumulation, or lipid peroxidation in Arabidopsis thaliana.
abstract: Gamma irradiation increased catalase activities at 0.1 kGy and decreased them at 10 kGy in Arabidopsis wild type and catalase-deficient mutants, cat3-1 and cat1 cat3. Irradiation induced DNA damage, H2O2 accumulation, and lipid peroxidation in both mutants as well as the wild type. Thus catalases might not be key enzymes protecting gamma irradiation-induced damage.
