Resumen en inglés Abstract Transporter proteins play an essential role in the uptake, trafficking and storage of metals in plant tissues. The Natural Resistance-Associated Macrophage Protein (NRAMP) family plays an essential role in divalent metal transport.We conducted bioinformatics approaches to identify seven NRAMP genes in the Phaseolus vulgaris genome, investigated their phylogenetic relation, and performed transmembrane domain and gene/protein structure analyses. We found that the NRAMP gene family forms two distinct groups. One group included thePv NRAMP 1,-6,and-7genesthat share a fragmented structure with a numerous exon/intron organization and encode proteins with mitochondrialor plastidial localization. The other group is characterized by few exons that encode cytoplasmic proteins. In addition,our data indicated that Pv NRAMP6 and -7may be involved in mineral uptake and mobilization in nodule tissues,while the genes Pv NRAMP1, -2, -3, -4and-5are potentially recruited during plant development. This data provided amore comprehensive understanding of the role of NRAMP transporters in metal homeostasis inP. vulgaris
