摘要：

Cherry tomatoes ( Solanum lycopersicum var. cerasiforme ), an economically important crop, are highly susceptible to gray mold caused by Botrytis cinerea during postharvest storage, resulting in deterioration of fruit quality. As a polyunsaturated fatty acid, arachidonic acid (ARA) has been shown to act as an elicitor to induce plant defense responses against pathogens. In the present work, we explored the inducing effects and mechanisms of ARA on gray mold resistance through physiological and transcriptomic analyses. Exogenous ARA increased the activities of defense-related enzymes, such as p...
