IRT3 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G226990 (IRT3) on durum wheat chromosome 7A encodes a ZIP family zinc transporter with copper, zinc, and metal ion transmembrane transporter activity, as well as iron channel activity and protein binding. This gene is associated with zinc, iron, and cadmium transport, response to zinc, meiosis, syngamy, leaf senescence, chromatin modeling, homologous chromosome pairing, and response to nematodes. The encoded protein localizes to the plasma membrane, plant-type vacuole, and extracellular regions. IRT3 is associated with zinc deficiency tolerance, cadmium uptake, zinc and iron homeostasis, seed development, and iron deficiency response. Studies of related genes in other species connect the family to copper, zinc, cadmium, and iron concentrations, copper transport, cadmium accumulation, iron accumulation, and zinc accumulation.
