PMIT1 — Oryza sativa Japonica

Summary

Os07g0258400 (PMIT1, also known as NRAMP1) encodes a member of the NRAMP family of metal ion transporters, with molecular functions including metal ion, manganese, iron, aluminium and cadmium transmembrane transporter activity. In rice, the gene is associated with iron uptake, metal transport, broad-spectrum disease resistance, and reactive oxygen species regulation. Studies of NRAMP5 link the family to cadmium accumulation in shoots and grain, manganese accumulation, yield, grain quality, root and xylem development, and cobalt toxicity tolerance. NRAMP6 connects the family to immunity and resistance. The encoded protein localises to the plasma membrane, endosome, vacuole, Golgi, and plasmodesmata. The gene is also associated with biological yield, grain yield, iron content, chlorophyll content, plant height, root length, and shoot and root dry weight.
