AP3M — Triticum turgidum subsp. durum

Summary

TRITD1AV1G155240, designated TtAP3M (also known as TtZIP4 or AP3M) on durum wheat chromosome 1A, encodes a protein with GTPase activity and protein binding capability. The gene is associated with clathrin adaptor complex, heterotrimeric G-protein complex, and endomembrane system localisation. It has been connected to meiosis, homologous chromosome pairing, vacuolar protein sorting, vesicle transport, plant organ morphogenesis, root development, lateral root development, geotropism, response to ethylene and jasmonic acid signalling, defence response to fungi, ROS metabolic process, and ER unfolded protein response. Associations include seed yield, plant height, leaf morphology, root thickness, nitrate uptake, salt tolerance, drought stress response, disease resistance, stomatal closure, cell death, seed germination, and responses to high temperature, oxidative stress, and ethylene. Related genes in other species link the family to nitrogen use efficiency, sodium homeostasis, and pathogen resistance.
