IRT3 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G067030 (IRT3) on durum wheat chromosome 1B encodes a zinc transporter of the ZIP family with copper, zinc, metal ion and iron channel transmembrane transporter activities, and protein binding. The gene is associated with zinc, iron and cadmium transport, response to zinc, leaf senescence, meiosis, syngamy, homologous chromosome pairing, chromatin modelling and response to nematode. Its product localises to the plasma membrane, plant-type vacuole and extracellular region. Associations with zinc deficiency tolerance, cadmium uptake, zinc and iron homeostasis, seed development, and iron deficiency response have been reported. Studies of related genes in other species link the family to grain yield, grain size, tiller number, amylose content, drought tolerance, root length, stomatal resistance, transpiration rate, and concentrations of copper, zinc, cadmium and iron.
