ABF3 — Triticum aestivum

Summary

TRAESCS5B02G139800 (symbol ABF3, also known as TaABF3-5B) encodes a bZIP transcription factor of the BZIP46-like family, possessing sequence-specific DNA binding and protein homodimerization activity, and is localized to the nucleus. In bread wheat, this gene is associated with pre-harvest sprouting, seed development and germination, seedling development, embryogenesis, pollen maturation, and upregulation of abscisic acid-mediated signaling. It is also linked to gibberellin metabolism and biosynthesis, TOR signaling, mRNA transcription, response to salt, blue light response, cellular homeostasis, and cell growth. Associations with agronomic traits include days to booting, grain number per spikelet, fruiting efficiency, seedling vigour, sprouting tolerance, frost damage, winter survival, canopy temperature, coleoptile length, root weight, stem and culm length, spikelet fertility, grain weight per spike, and yield. Studies of related genes in other species link the family to drought tolerance, freezing tolerance, and abscisic acid sensitivity.
