Abstract
A rice blast controlling agent, isoprothiolane (diisopropyl 1, 3-dithiolan-2-ylidenemalonate), stimulated the reduction of methionine sulfoxide to methionine by the rice plant. In the presence of isoprothiolane, the methionine/(methionine + its sulfoxide) ratio was increased to 129 - 208% of the control. The ethylene production by the plant was also enhanced by isoprothiolane, probably because methionine is an important precursor of ethylene. The non-parasitic damping-off caused by chilling stress on rice seedlings was effectively prevented with the application of isoprothiolane as well as ethephon, which easily decomposes to ethylene and acids. Therefore, the ethylene level modified by isoprothiolane and ethephon can contribute to their protective activity against the non-parasitic damping-off of rice seedlings. Indeed, a close relationship between the ethylene level and the protective activity against damping-off was obtained with isoprothiolane, but not with ethephon. Endogenous ethylene seems to be more effective in controlling the damping-off than exogenous ethylene from ethephon.
