BZIP50 — triticum aestivum

Summary

TaBZIP50 (TRAESCS7A02G398400) on wheat chromosome 7A encodes a bZIP transcription factor with histone H3 methylase activity, specifically H3K4 methylase activity, and DNA-binding transcription activator activity. It is associated with the unfolded protein response, ER stress response, and hyperosmotic salinity response, as well as lateral root branching, simple leaf morphogenesis, and the transition from vegetative to reproductive phase. The gene has been linked to grain yield, grain filling period, ear number, plant height, flowering time, photosynthetic rate, root morphology traits including root branching and thickness, and responses to temperature stress, salt stress, and disease tolerance. It localises to the ER membrane, nuclear envelope, and nucleus. Studies of related genes in other species connect the family to salt tolerance, osmotic stress tolerance, thermotolerance, and pathogen resistance.
