Systemic reduction of rice blast by inhibitors of antioxidant enzymes

 0.00

Abstract: Catalase inhibitor aminotriazole or superoxide dismutase inhibitor diethyl dithiocarbamate applied to rice leaves reduced the disease severity on those blast-inoculated upper leaves which emerged later. Both treatments induced superoxide production in inoculated leaves. It is suggested that the local boost of reactive oxygen levels may have subsequent effects leading to systemic acquired resistance. The resistance may also be realized through oxidative burst in the protected leaves, which were primed by the treatments.
