Many plants release a specific bouquet of volatile organic compounds when attacked by insect herbivores. These volatiles can consist of compounds from all major pathways for secondary metabolites including terpenoids (mono- and sesquiterpenes), alkaloids (indole), and phenylpropanes (methyl salicylate), as well as green-leaf volatiles.

These VOCs are herbivore– induced plant volatiles (HIPV) HIPV and act as cues for natural enemies of the insect herbivore, for example parasitic wasps.

To distinguish between “self” and “nonself” during pathogen infection, plants possess pattern recognition receptors (PRRs) that perceive microbe-associated molecular patterns (MAMPs) which are conserved among a specific class of microorganisms (such as chitin for fungi, flagella for bacteria) but are absent in the host.

Perception of MAMPs or DAMPs by cell surface PRRs initiates a localized basal defense response called MAMP triggered immunity which inhibits the growth and activity of nonadapted pathogens or pests.
