HEL — Capsicum annuum

Summary

T459_22169 (HEL, also known as PR4) in pepper (Capsicum annuum) chromosome 8 encodes a protein of the PR4 family, containing a Barwin domain. The encoded product exhibits RNA nuclease, chitin-binding, sugar-binding, hydrolase, transmembrane receptor protein serine/threonine kinase, and protein-binding activities. HEL is associated with systemic acquired resistance, response to virus, response to herbivore, cell death, hypersensitive response-programmed cell death, virus-induced post-transcriptional gene silencing, response to ethylene, cell wall modification, phloem transport, secretion, detoxification, nitrogen fixation, spore germination, protein processing, and leaf vascular tissue pattern formation. It localizes to secretory vesicles, the extracellular region, and the plasma membrane. The gene is associated with disease resistance, pathogen defense, wilt symptom development, resistance to Botrytis cinerea, salt tolerance, premature senescence with leaf cell death, and abnormal leaf venation with reduced vein number.
