Difese indotte nelle piante: l'interazione con insetti e microrganismi

Insects and microorganisms interactions and the induction of plant defence Insect-plant interactions are modulated by a number of factors regulating plant metabolism and response. In fact, the attacking herbivore is the first source of molecules active on plants, with the secretions necessary for its feeding activity. Among these, sali- vary secretions and gut regurgitate play a key role. Thus, the insect feeding produces a mechanical damage that activates plant signaling, and this is reinforced by elicitors delivered at the feeding site. The network of molecular pathways underlying the plant metabolic response is further conditioned by the microbiota associated with plants.
