PMIT1 — Brassica juncea

Summary

BjPMIT1 (BJUB06G01080S) on chromosome B06 of Indian mustard (Brassica juncea) encodes a member of the NRAMP family of metal ion transporters, with molecular functions including iron channel activity and transmembrane transporter activities for manganese, cadmium, and aluminium ions. The gene is associated with the transport and homeostasis of multiple metals, including cadmium, manganese, iron, lead, and aluminium, as well as with cellular cation homeostasis and response to aluminium. Localised to the plasmalemma, BjPMIT1 is associated with manganese and iron uptake, manganese toxicity tolerance, seed iron accumulation and loading, root growth, and metal translocation. Related genes in other species are linked to iron transport, iron toxicity resistance, plant growth, and traits such as iron and manganese sensitivity, cadmium concentration, leaf chlorosis, chlorophyll content, root morphology, and stomatal opening.
