AP3M — Triticum turgidum subsp. durum

Summary

TRITD1BV1G142090 (TtAP3M, also known as TtZIP4 or AP3M) on durum wheat chromosome 1B encodes a protein with GTPase activity and protein binding capability. The gene is associated with clathrin adaptor complexes, the heterotrimeric G-protein complex, and the endomembrane system, and is linked to vacuolar protein sorting, vesicle transport, and intracellular protein transport. TtAP3M is associated with meiosis, homologous chromosome pairing, plant organ morphogenesis, root development, lateral root development, geotropism, and regulation of root development. It is also associated with responses to ethylene, jasmonic acid, ATP, and defence against fungi, as well as ROS metabolism and ER unfolded protein response. The gene is linked to numerous agronomic traits including seed yield, plant height, root thickness, salt tolerance, drought stress response, disease tolerance, nitrogen use efficiency, and stomatal closure.
