Genome-wide identification and evolutionary analysis of NRAMP family genes in tomato (Solanum lycopersicum L.) under cadmium and salt stress.

ABSTRACT: The Natural Resistance-Associated Macrophage Protein (NRAMP) family consists of integral membrane transporters essential for divalent metal ion transport in plants. This study aimed to identify and characterize NRAMP genes in tomato (Solanum lycopersicum), performing genome-wide classification, and cis-elements analysis, revealing four SlNRAMP genes in the tomato genome. Phylogenetic analysis classified the four SlNRAMP proteins into two distinct groups, group A and group B. The encoded proteins ranged in length from 509 amino acids in SlNRAMP3 to 773 amino acids in SlNRAMP4. The number of predicted transmembrane domains in SlNRAMPs ranged from 12 to 14. Expression analysis in 20 samples from three key developmental stages were collected for metabolic profiling and RNA-seq, revealing that
