Receptor kinases in plant responses to herbivory

Plants have the ability to detect and respond to biotic stresses. They contain pattern recognition receptors (PRRs) that specifically recognize conserved molecules from their enemies and activate immune responses. In this review, I discuss recent efforts to discover PRRs for herbivory-associated cues that originate from oral secretions, eggs, damaged plant cells or secondary endogenous signals. Although several potential PRRs have been identified and shown to confer resistance to insects, proof of direct binding to a ligand is scarce and there are still many uncharacterized ligand-receptor pairs. However, several studies suggest that, like for microbial pathogens, plants use similar PRR complexes to detect herbivory.

Automated summary

Plants have the ability to detect and respond to biotic stresses through pattern recognition receptors (PRRs) which specifically recognize molecules from enemies and activate immune responses. Research on PRRs related to herbivory signals is still in its early stages, with potential PRRs identified but lacking direct binding evidence to ligands, indicating many uncharacterized ligand-receptor pairs.
