IRT3 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G150140 (IRT3) on durum wheat chromosome 7B encodes a ZIP family metal transporter with copper, zinc, and iron ion transmembrane transporter activity, as well as protein binding capability. The gene is associated with zinc and iron transport, cadmium transport, response to zinc, leaf senescence, meiosis, homologous chromosome pairing, and response to nematodes. It has been linked to zinc deficiency tolerance, cadmium uptake, zinc homeostasis, seed development, and iron homeostasis. The encoded protein localises to the plasma membrane, plant-type vacuole, and extracellular regions. Studies of related genes in other species connect the family to grain yield, grain size, tiller number, root length, drought tolerance, amylose content, and stomatal resistance, as well as copper, zinc, iron, and cadmium accumulation in various plant tissues.
