The complete chloroplast genome of copper-tolerance plant Elsholtzia splendens.

Elsholtzia splendens is a copper-tolerance plant colonized in copper mines in southern China. In this study, we sequenced and de novo assembled the complete chloroplast genome of E. splendens. The complete chloroplast genome is 150,761 bp (37.8% of GC) in length and contains 87 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis revealed that among the 11 Lamiaceae species, Perilla citriodor is the closest relative of E. splendens. The complete chloroplast genome of E. splendens provides a valuable resource for comparative and evolutionary analysis among Lamiaceae species and may be helpful in understanding the molecular mechanism of copper tolerance in E. splendens.
