GS2 — Triticum turgidum subsp. durum

Summary

TRITD6AV1G170910, also known as GS2, encodes a growth-regulating factor (GRF) protein containing QLQ and WRC domains and is annotated as a transcription coactivator with ATP and protein binding activity. Localized to the nucleus, this durum wheat gene on chromosome 6A is associated with seed development, grain filling, grain weight, and protein content, as well as leaf and floral organ development, root meristem growth, cell proliferation, and responses to cold, gibberellin, and deep water. It is linked to water use efficiency, anthocyanin content, oxidative stress response, and ovary, pistil, and anther morphology traits. Related genes in other species link the family to grain size, yield, heat and cold tolerance, organ size, and regeneration efficiency.
