IRT3 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G059880 (IRT3) on durum wheat chromosome 1A encodes a ZIP family metal transporter with copper ion, zinc ion, and iron channel transmembrane transporter activity, as well as protein binding capability. The gene is associated with zinc, iron, and cadmium transport, response to zinc, leaf senescence, meiosis, syngamy, homologous chromosome pairing, chromatin modeling, and response to nematode. The encoded protein localizes to the plant-type vacuole, plasmalemma, and extracellular regions. IRT3 is associated with zinc deficiency tolerance, cadmium uptake, zinc homeostasis, seed development, iron homeostasis, and iron deficiency response. Studies of related genes in other species connect the family to copper, zinc, iron, and cadmium accumulation, grain traits, root and shoot development, drought tolerance, and grain yield.
