When exposed to herbivore-infested plant volatiles or volatiles from artificially damaged plants, intact plants enhance their defense against herbivores. This phenomenon is called plant-plant communication. Here, we outline studies on plant-plant communication from both ecological and plant physiological perspectives. Regarding the ecological perspective, we give an overview of studies showing that plant-plant communication affect direct and indirect defense levels of exposed plants, and herbivore performance on exposed plants. Cases of kin selection in plant-plant communications and intra-plant communication via airborne signals are also summarized. Regarding the plant physiological perspective, we give an overview of studies that showed specific responses of receiver plants to a volatile molecular species, to different configurations of a volatile molecular species and to blends of volatiles. Furthermore, we review the signaling pathways involved, priming, sensitivity, and how plants receive volatile compounds in plant-plant communications.
