Genome-wide identification, evolution, and expression analysis of StNRT (nitrate and peptide transporter) gene family in potato (Solanum tuberosum L.)

This study systematically characterizes the gene structure, conserved protein domains and motifs, evolutionary relationships, and expression profiles of the StNRT gene family in S. tuberosum. These findings provide critical insights into the functional mechanisms of StNRTs, and identify candidate genes for improving the nitrogen use efficiency (NUE) in potato cultivation.
