Abstract
The recognition of phytophagous insects by plants induces a set of very specific responses aimed at deterring tissue consumption and reprogramming plant metabolism and development to tolerate herbivory. This recognition requires the plant's ability to perceive chemical cues generated by the insects and to distinguish a particular pattern of tissue disruption. Relatively little is known about the molecular basis of insect perception by plants and the signaling mechanisms directly associated with this perception. Importantly, the insect feeding behavior (piercing‐sucking versus chewing) is a decisive determinant of the plant's defense response, and the mechanisms used to perceive insects from different feeding guilds may be distinct. During insect feeding, components of the saliva of chewing or piercing‐sucking insects get into contact with plant cells and elicitors or effectors present in this insect‐derived fluid are perceived by plant cells to initiate the activation of specific signaling cascades.
