SAR1 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G134620 (TtSAR1) on durum wheat chromosome 7B encodes a small GTPase of the SAR1 family, possessing GTPase, GTP-binding, phospholipase activator and G protein activities. The gene is associated with COPII vesicle coat formation, ER-to-Golgi transport, vesicle organization, secretion, membrane organization, intracellular protein transport, detoxification, cell division and protein transport. Its product localizes to the ER membrane, ER exit site, Golgi membrane, COPII vesicle coat, cilial membrane, microtubule-organizing centre and spindle. Studies of related genes in other species link the SAR1 family to root length and seed germination traits.
