IRT3 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G195700 (symbol IRT3, also known as TtZIP4, TtZIP7, TtZIP9, TtZIP10, ZIP4, ZIP7, ZIP9, ZIP10) on durum wheat chromosome 7A encodes a member of the ZIP metal transporter family with copper ion, zinc ion, and metal ion transmembrane transporter activity, as well as iron channel activity and protein binding. The gene is associated with zinc, iron, and cadmium transport, response to zinc, leaf senescence, meiosis, syngamy, homologous chromosome pairing at meiosis, chromatin modeling, and response to nematode. Its product localizes to the plant-type vacuole, plasmalemma, and extracellular regions. 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 copper transport, cadmium accumulation, and iron and zinc accumulation.
