HEL — Capsicum annuum

Summary

CaHEL (T459_22168) on pepper chromosome 8 encodes a protein of the PR4 family, containing a Barwin domain and a RlpA-like superfamily fold, with annotated molecular functions including RNA nuclease activity, chitin binding, sugar binding, transmembrane receptor protein serine/threonine kinase activity, and protein binding. The gene is associated with defence response to bacteria, response to virus, response to herbivore, response to ethylene, systemic acquired resistance, virus-induced PTGS, HR-PCD, cell death, cell wall modification, phloem transport, secretion, nitrogen fixation, spore germination, leaf vascular tissue pattern formation, and auxin and brassinosteroid mediated signalling. It localises to secretory vesicles, the extracellular region, and the plasmalemma. CaHEL is linked to disease resistance, pathogen defense response, wilt symptom development, resistance to Botrytis cinerea, salt tolerance, leaf vein morphology trait, vascular development, premature senescence, and leaf cell death. Related genes in other species connect the family to leaf venation and vascular development.
