PMIT1 — Brassica juncea

Summary

BjPMIT1, located on chromosome B05 of Indian mustard (Brassica juncea), encodes a member of the NRAMP family of metal ion transporters. The gene product exhibits transmembrane transporter activity for iron, manganese, cadmium, and aluminium ions, and is localized to the plasma membrane. BjPMIT1 is associated with the transport and homeostasis of multiple metals, including manganese, iron, cadmium, lead, and aluminium, as well as responses to aluminium stress. The gene has been linked to manganese and iron uptake, manganese toxicity tolerance, seed iron accumulation and loading, root growth, and manganese translocation. Related genes in other species have been linked to iron transport, iron toxicity resistance, and plant growth.
