DMT1 — Cicer arietinum

Summary

CaDMT1 (LOC101515280) on chickpea chromosome 7 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 the transport and homeostasis of several metals: it is linked to manganese, iron and lead ion transport, cellular manganese and iron ion homeostasis, and multicellular organismal iron ion homeostasis. CaDMT1 has been connected to responses to iron, zinc, bacteria and nematodes, as well as to positive regulation of reactive oxygen species metabolism and nitric oxide storage. Its product localises to the tonoplast, vacuolar membrane, trans-Golgi network membrane, plasmodesmata, plastid and Golgi complex. Related genes in other species link the family to iron mobilisation and reutilisation, manganese accumulation, cadmium transport, photosystem II function, pathogen resistance and seed germination.
