DMT1 — Cicer arietinum

Summary

CaDMT1 (LOC101504230) on chickpea chromosome 8 encodes a member of the NRAMP family of metal ion transporters, with molecular functions including metal ion, manganese ion and transmembrane transporter activity. The gene is associated with manganese and iron ion membrane transport, cellular metal ion homeostasis, response to iron and zinc, positive regulation of reactive oxygen species metabolism, defence response to bacteria, response to nematode, and NO storage. Its product localises to the tonoplast, vacuolar membrane, trans-Golgi network membrane, plasmodesma, plastid and Golgi complex. Associations include copper homeostasis, iron remobilization, iron localization in seeds, growth under manganese deficiency, protein sorting, manganese transport and seed germination. Related genes in other species link the family to photosystem II function, iron deficiency response, manganese and zinc accumulation, pathogen resistance, cadmium transport and vacuolar iron transport.
