HEL — Cucumis melo

Summary

MELO3C004385.2 (symbol HEL, preferred name CmHEL) on melon chromosome 6 encodes a protein of the PR4 family, containing a Barwin domain and annotated with RNA nuclease, chitin-binding, sugar-binding, hydrolase, transmembrane receptor protein serine/threonine kinase, and protein-binding activities. The gene is associated with defence responses to bacteria, fungi, viruses, and herbivores, as well as systemic acquired resistance, hypersensitive response-programmed cell death, ethylene response, auxin and brassinosteroid signalling, phloem transport, leaf vascular tissue pattern formation, and glycan biosynthesis. It localises to secretory vesicles, the extracellular region, and the plasma membrane. Associations include leaf vein morphology, pathogen defence, wilt symptom development, resistance to Botrytis cinerea, salt tolerance, premature senescence, leaf cell death, and abnormal leaf venation. Related genes in other species link the family to vascular development and leaf venation.
