HEL — Capsicum annuum

Summary

CaHEL (T459_22173) on pepper chromosome 8 encodes a PR4 family protein containing a Barwin domain and a chitin-binding domain, with annotated RNA nuclease, chitin-binding, sugar-binding, hydrolase, transmembrane receptor protein serine/threonine kinase, and protein-binding activities. It is associated with defence responses including response to virus, bacteria, herbivore, ethylene, systemic acquired resistance, hypersensitive response cell death, and virus-induced PTGS, as well as cell wall modification, phloem transport, secretion, nitrogen fixation, spore germination, leaf vascular tissue pattern formation, and auxin and brassinosteroid signalling. The gene is linked to disease tolerance, resistance to Botrytis cinerea, salt tolerance, leaf vein morphology, premature senescence, leaf cell death, and abnormal leaf venation with reduced vein number. It localises to secretory vesicles, the extracellular region, and the plasma membrane.
