HVA1 — Triticum aestivum

Summary

TRAESCS4B02G332800, also known as HVA1 or Wrab17 on bread wheat chromosome 4B, encodes the Wrab17 protein, a cold-responsive protein family member. The gene is associated with abiotic stress tolerance, including cold stress tolerance, as well as ABA responsiveness. It is associated with winter survival, cell membrane stability, and grain yield, along with traits such as plant height, tiller number, anthesis time, and chlorophyll content. Annotated biological processes include cold acclimation, seed germination, embryogenesis, regeneration, and cellular homeostasis, with the protein localised to the nucleus. Studies of related genes in other species connect the family to seed dormancy, root length, and flavonoid content.
