Comprehensive Genome-Wide Analysis and Expression Profiling of <i>Pathogenesis-Related Protein 1</i> (<i>PR-1</i>) Genes in <i>Salvia miltiorrhiza</i>.

ABSTRACT: The pathogenesis-related 1 (PR-1) gene family is essential for plant defense and stress response. In this study, 11 SmPR-1 genes were identified in Salvia miltiorrhiza through comprehensive genomic analysis, all of which encoded proteins with conserved CAP (cysteine-rich secretory protein, antigen 5, and pathogenesis-related 1) domains and signal peptides. Phylogenetic analysis categorized these genes into five evolutionary clusters, reflecting their evolutionary divergence. Chromosomal localization analysis revealed that the SmPR-1 gene family is distributed across three chromosomes: Chr1 contains six genes, Chr6 contains three, and Chr8 contains one. Intraspecific collinearity analysis indicated segmental duplications of SmPR-1-5 and SmPR-1-11 on
