PMIT1 — Brassica juncea

Summary

BjPMIT1 (BJUA07G37990S) on Indian mustard chromosome A07 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, and with responses to aluminium stress. It is linked to manganese and iron uptake, manganese toxicity tolerance, seed iron accumulation and loading, root growth, and manganese translocation and homeostasis. 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, stomatal opening and plant growth traits.
