HSFB4C — triticum aestivum

Summary

TaHSFB4C (TRAESCS5D02G243900) on bread wheat chromosome 5D encodes a protein with an HSF-type DNA-binding domain, possessing DNA-binding transcription factor activity and sequence-specific DNA binding. It is associated with cellular response to heat, response to desiccation, oxidative stress, brassinosteroid signaling, and regulation of transcription by RNA polymerase II. The gene is linked to numerous agronomic traits including heat and cold tolerance, radiation use efficiency, canopy temperature, heading time, days to flowering and maturity, grain size, protein and zinc content, seed dormancy, germination rate, stem rust and stripe rust disease responses, common bunt spike incidence, aluminum tolerance, and leaf width. It localizes to the nucleus and cytoplasm and is associated with cell wall polysaccharide breakdown, seed germination, and auxin signaling. Studies of related genes in other species link the family to salt tolerance and stomatal opening.
