Abstract
When plants begin to grow, they cannot move about, so in order to adapt to different environments they have acquired various strategies during the process of their evolution. Plants require particularly ingenious survival strategies in order to have mutually-beneficial symbiotic relationships with organisms such as microbes, insects, and other plants. Recently, it has been revealed that plants employ chemical communication as a strategy, that is, they use chemical substances to transmit information to partners. These chemicals contain substances that are passively accumulated in plant bodies, such as phytoalexins, and those that are aggressively dispersed outside of plants, such as allelochemicals. Among the main chemical substances are terpenes and volatile oxylipins. Research is being conducted on the mechanisms by which these chemical substances are received by plants.
