IRT3 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G226820, designated IRT3 (also known as TtZIP4, TtZIP7, TtZIP9, TtZIP10, ZIP4, ZIP7, ZIP9, ZIP10), encodes a zinc transporter of the ZIP family on durum wheat chromosome 7A. The protein exhibits copper, zinc, and metal ion transmembrane transporter activity, as well as iron channel activity and protein binding. It is associated with zinc ion membrane transport, iron transport, cadmium transport, response to zinc, leaf senescence, meiosis, syngamy, homologous chromosome pairing, chromatin modeling, and response to nematode. The product localizes to the plant-type vacuole, plasmalemma, and extracellular regions. The gene is associated with zinc deficiency tolerance, cadmium uptake, zinc and iron homeostasis, seed development, and crossover frequency. Related genes in other species link the family to iron and zinc accumulation, cadmium accumulation, and grain homeostasis.
