BZIP9 — triticum aestivum

Summary

TaBZIP9 (TRAESCS6D02G144400) on wheat chromosome 6D encodes a bZIP transcription factor of the RISBZ3/4/5 family with DNA-binding, transcription corepressor, and phosphorelay response regulator activities. It is associated with abscisic acid biosynthesis and responses to abscisic acid, glucose, sucrose, and starvation. The gene is linked to regulation of starch biosynthesis, seed maturation, gibberellic acid homeostasis, and negative regulation of transcription and translation. TaBZIP9 is associated with grain weight, grain yield, heat tolerance, disease tolerance, salt tolerance, osmotic adjustment capacity, root thickness, nitrogen sensitivity, and female sterility. It localises to both the nucleus and cytoplasm. Studies of related genes in other species link the family to circadian phase regulation, drought tolerance, seed maturation, and amino acid metabolism.
