IRT1 (TRAESCS4A02G294300) — triticum aestivum
Summary
TRAESCS4A02G294300, designated TaIRT1 on bread wheat chromosome 4A, encodes a member of the ZIP family of metal transporters with transmembrane transporter activity for copper, zinc, manganese, iron, and cadmium ions. The gene is associated with zinc accumulation, iron homeostasis, and responses to iron and zinc deficiency. It has been linked to grain yield, plant height, tiller number, root fresh weight, root length, grain filling period, and cadmium concentration. Associations also include nickel and cadmium transport, cellular and multicellular iron ion homeostasis, detoxification, downregulation of abscisic acid signalling, response to hypoxia, and cell wall organization. The protein localizes to the plasma membrane, endosome, late endosome membrane, and ESCRT I complex. Related genes in other species link the family to iron acquisition, cadmium uptake, and metal accumulation.
