PMIT1 — Brassica juncea

Summary

BjPMIT1 (BJUA07G22610S) on chromosome A07 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, and with responses to aluminium. It is linked to manganese and iron uptake, manganese toxicity tolerance and translocation, seed iron accumulation and loading, root growth, and metal uptake. The encoded protein localises to the plasmalemma. Related genes in other species are linked to iron and manganese sensitivity, iron content and concentration, cadmium concentration, leaf chlorosis, chlorophyll content, root length and morphology, stomatal opening, photochemical quenching, and plant growth.
