BZIP19 — Triticum aestivum

Summary

TRAESCS5A02G143300, designated BZIP19 or TaDeg7 on wheat chromosome 5A, encodes a bZIP domain-containing protein that acts as a DNA-binding transcription factor. The gene is associated with photoprotection, nonphotochemical quenching, and photosynthetic activity, as well as with response to desiccation, oxidative stress, and brassinosteroid signaling. It has been linked to cell wall polysaccharide breakdown, mucilage extrusion from seed coat, virus-induced PTGS, auxin signaling, and epigenetic regulation of gene expression. Associations with stripe rust, drought tolerance, radiation use efficiency, and SDS sedimentation have been noted. The encoded protein localises to the nucleus and is connected to seed development, regulation of seed size, and root and reproductive structure development. Studies of related genes in other species link the family to seed germination and salt tolerance.
