GS2 — Triticum turgidum subsp. durum

Summary

TRITD4AV1G251150, also known as GS2, encodes a growth-regulating factor (GRF) protein containing QLQ and WRC domains and is annotated with transcription coactivator activity, ATP binding, and protein binding, localizing to the nucleus. In durum wheat, this gene is associated with seed development, grain filling, grain protein content, seed weight, and grain yield. It is linked to responses to gibberellin, cold, and deep water, as well as positive regulation of cell cycle, cell division, root meristem growth, and leaf growth and development traits. Associations also include water use efficiency, anthocyanin content, oxidative stress response, and floral organ, ovary, pistil, and anther morphology traits. Studies of related genes in other species link the family to grain size, seed size, organ growth, heat and cold tolerance, salt tolerance, and plant regeneration efficiency.
