HEL — Triticum aestivum

Summary

TRAESCS2B02G581900 (HEL, PR4) on wheat chromosome 2B encodes a Barwin-domain protein with RNA nuclease, chitin-binding, hydrolase, sugar-binding, transmembrane receptor serine/threonine kinase, and protein-binding activities. It is associated with antifungal innate immune response, killing of cells of other organism, response to herbivore and virus, systemic acquired resistance, HR-PCD, detoxification, glutathione metabolism, coumarin anabolism, phenylpropanoid metabolism, flavonoid anabolism, lignin anabolism, secondary cell wall biogenesis, phloem transport, leaf vascular tissue pattern formation, and auxin signaling. The protein localizes to secretory vesicles, the extracellular region, and the plasmalemma. Associations include leaf vein morphology trait, wheat powdery mildew disease response, stem rust, grain weight, salt tolerance, and resistance to Botrytis cinerea. Related genes in other species link the family to leaf venation and vascular development.
