PMIT1 — Brassica juncea

Summary

BjPMIT1 (BJUA02G18950S) on chromosome A02 of Indian mustard encodes a member of the NRAMP family of metal ion transporters, with molecular functions including iron, manganese, cadmium, and aluminium ion transmembrane transporter activity and iron channel activity. The gene is associated with the transport and homeostasis of multiple metals, including cadmium, manganese, iron, lead, and aluminium, as well as with responses to aluminium toxicity. It is linked to manganese and iron uptake, manganese toxicity tolerance, seed iron accumulation and loading, root growth, and manganese translocation. The encoded protein localises to the plasma membrane. Studies of related genes in other species link the family to iron and manganese sensitivity, iron content, cadmium concentration, leaf chlorosis, chlorophyll content, root morphology, and plant growth traits.
