Isothiocyanates (ITCs) are degradation products of glucosinolates in crucifer plants and have repellent effect on insects. pathogens and herbivores. In this study, we report that exogenously applied ally! isothiocyanate (AITC) induced stomata! closure in Arabidopsis via production of reactive oxygen species (ROS) and nitric oxide (NO). and elevation of cytosolic Ca 2'. AITC-induced stomatal closures were partially inhibited by an inhibitor of NADPH oxidase and completely inhibited by glutathione monoethyl ester (GSHmee).
