IRT1 — Brassica oleracea

Summary

BoIRT1 (BOLC102_C07P055420.1) on cabbage chromosome 7 encodes a ZIP family metal transporter with iron channel activity and copper, manganese, zinc, and cadmium ion transmembrane transporter activities, along with phosphoinositide, ubiquitin, mRNA, and protein binding. This gene is associated with metal homeostasis, iron deficiency tolerance, and responses to cadmium, zinc, chromium, and uranium. It is linked to photosynthetic rate and efficiency, chlorophyll content, plant growth and development, root and leaf development, chloroplast development, disease resistance, and circadian period length. Localization evidence connects BoIRT1 to the plasma membrane, endosome, late endosome membrane, trans-Golgi network, ESCRT I complex, and nucleus. Related genes in other species are linked to iron uptake and translocation, nickel accumulation, cadmium sensitivity, and vacuolar biogenesis.
