Genome-wide characterization of NRAMP metal transporters reveals functional diversity for heavy metal tolerance in Onobrychis viciifolia.

ABSTRACT: Heavy metal contamination poses significant threats to global food security worldwide, necessitating the development of crops with enhanced metal tolerance. Natural resistance-associated macrophage proteins (NRAMPs) constitute a conserved family of divalent metal transporters crucial for maintaining cellular metal homeostasis and conferring heavy metal tolerance in plants. Despite extensive characterization in model species, comprehensive genomic analysis of NRAMP gene families in forage legumes remains limited. Here, we report the first genome-wide identification and characterization of the NRAMP transporter family in sainfoin (Onobrychis viciifolia), a high-value forage legume with exceptional nutritional properties. Phylogenetic analysis, gene structure examination, conserved motif iden
