High affinity manganese (Mn) transporter involved in Mn acquisition from the soil. Required for Mn uptake into the root in conditions of low Mn availability. Can transport iron (Fe), cadmium (Cd) and cobalt (Co). By Mn and Fe deficiency in roots. No visible phenotype under normal growth condition, but under Mn limitation, very slow growth and unable to take up Mn. Belongs to the NRAMP (TC 2.A.55) family.
