Plants detect pests and pathogens through cell surface receptors, which bind extracellular ligands and initiate defense signal transduction. Many well-characterized receptors detect pathogen-associated molecular patterns (PAMPs), but receptors for other pest classes such as chewing herbivores are not well understood.
We recently identified the first cell surface receptor to directly detect a ligand directly associated with chewing heribivory, an 11-aa peptide termed inceptin (Steinbrenner et al. 2020, PNAS). Inceptin receptor, or INR, confers binding, signaling, and defensive outputs in response to low nanomolar concentrations of inceptin peptide. INR is unique to specific legume species. Since inceptins are widespread in caterpillar oral secretions, INR likely confers broad spectrum recognition of herbivores.
