Q — Triticum aestivum

Summary

TRAESCS5D02G486600, designated Q and also known as TaTOE2-5D, TaSMZ-5D and TaSNB-5D on bread wheat chromosome 5D, encodes a DNA-binding transcription factor containing an AP2/ERF domain. The product exhibits transcription corepressor and coactivator activity, binds transcription cis-regulatory regions, homodimerizes, and localises to the nucleus and cytoplasm. This gene is associated with the regulation of floral organ abscission, seed abscission and development, endosperm development, starch biosynthesis, nitrogen utilization, gibberellic acid homeostasis, seed dormancy, and meristem development. It is linked to numerous agronomic traits including heading time, spikelet number and density, grain yield and quality, seed set, plant vigour, stem rust response, canopy temperature, and emergence time. Studies of related genes in other species connect the family to flowering time, photoperiodic flowering, juvenile-to-adult phase transition, innate immunity, and de novo root regeneration.
