摘要： Perillyl alcohol (POH), a natural monoterpene, exhibits potent anticancer activity and may also play a role in inhibiting plant pathogens. However, its mechanism of action on controlling gray mold of tomato remains unclear. In this study, we investigated the effect of POH on Botrytis cinerea infected tomato. The results demonstrate that POH inhibits the in vitro growth of B. cinerea by disrupting plasma membrane integrity, thereby exhibiting broad-spectrum antimicrobial activity. Metabolomic analysis revealed that POH activated jasmonic acid (JA) biosynthesis and induced JA production in B. cinerea-treated tomato. Furthermore, POH upregulated the expression of defense-related genes and induced ROS accumulation. Specifically, POH induced the accumulation of kaempferol in tomato and exogenous kaempferol disrupted the plasma membrane of B. cinerea and induced ROS production. Taken together, POH can inhibit the development of gray mold, besides enhancing plant immunity against B. cinerea by inducing JA accumulation and promoting kaempferol biosynthesis.
