HEL — Daucus carota subsp. sativus

Summary

DCAR_014053 (DcHEL, also known as DcPR4A, DcPR4B, DcWIN1, and DcWIN2) on carrot chromosome 4 encodes a protein of the PR4 family, containing a Barwin domain and annotated with RNA nuclease, chitin-binding, sugar-binding, hydrolase, and transmembrane receptor protein serine/threonine kinase activities. The gene is associated with defence responses, including response to herbivore, virus, bacteria, and fungi, as well as systemic acquired resistance, immune response, and hypersensitive response-programmed cell death. It is linked to phloem transport, leaf vascular tissue pattern formation, ethylene response, and auxin and brassinosteroid signalling. Localisation evidence connects the product to secretory vesicles, the extracellular region, and the plasma membrane. Associations with traits include leaf vein morphology, pathogen resistance (including to Botrytis cinerea), salt tolerance, and premature senescence with leaf cell death.
