IRT1 — Brassica napus

Summary

BnIRT1 (DARMORV10_A01P11620.1) on chromosome A01 of oilseed rape encodes a ZIP family metal transporter with iron channel activity and transmembrane transporter activities for copper, manganese, zinc, and cadmium ions. It also exhibits phosphoinositide, ubiquitin, mRNA, and protein binding. The gene is associated with metal homeostasis, iron deficiency response and tolerance, and the transport and accumulation of iron, cadmium, zinc, and nickel. It has been linked to photosynthetic rate and efficiency, chlorophyll and carotenoid content, leaf chlorosis, stomatal resistance, germination rate, root and lateral root development, plant growth, disease resistance, and responses to salt, chromium, and uranium. The encoded protein localises to the plasmalemma, endosome, late endosome membrane, TGN, ESCRT I complex, and nucleus, and is linked to pollen germination, hypoxia response, and abscisic acid signalling.
