HEL — Capsicum annuum

Summary

CaHEL (T459_32257) on pepper chromosome PGAv.1.6.scaffold606 encodes a wound-induced protein WIN2 that belongs to the PR4 family and contains a Barwin domain. The gene product is associated with RNA nuclease activity, chitin binding, and hydrolase activity, and has been linked to defence responses including response to virus, bacteria, and herbivore, as well as systemic acquired resistance, hypersensitive response cell death, and ethylene response. CaHEL is associated with disease resistance, resistance to Botrytis cinerea, salt tolerance, leaf vein morphology, and vascular development. Localisation evidence places the protein in secretory vesicles, the extracellular region, and the plasma membrane. Related genes in other species link the family to leaf venation and vascular development.
