IRT1 — Brassica napus

Summary

BnIRT1 (DARMORV10_C07P50530.1) on chromosome C07 of oilseed rape (Brassica napus) encodes a ZIP family metal transporter with iron channel activity and transmembrane transporter activities for copper, manganese, zinc, and cadmium ions, along with phosphoinositide, ubiquitin, mRNA, and protein binding. The gene is associated with metal homeostasis, including iron, zinc, and cadmium accumulation and transport, as well as iron deficiency tolerance and response. It has been linked to agronomically important traits such as photosynthetic rate, chlorophyll content, leaf chlorosis, stomatal resistance, germination rate, carotenoid content, and plant growth and development. Additional associations include pollen germination, cellular response to hypoxia, response to bacteria, downregulation of abscisic acid signaling, and localization to the plasmalemma, endosome, and ESCRT I complex. Related genes in other species are linked to iron uptake, plant growth, and metal accumulation.
