Outline of Final Research Achievements

In this study, I have focused on the mixed-planting of tomato/basil as a means of elucidating molecular mechanisms of plant-to-plant signaling. Using this system, I found that volatiles released from upper part of basil induces the expression of several signaling factor of MAP kinases and ROS-related genes, and significantly enhances wound responsive jasmonic acid signaling in tomato plants. Tomato plants exposed to basil essential oil alleviated the feeding damage of Spodoptera litura. On the other hand, essential oil derived from thyme potentiated salicylic acid signaling and induced disease resistance to tomato.
