The complete chloroplast genome sequence of the medicinal plant, Dracocephalum rupestre (Lamiaceae).

Dracocephalum rupestre (tribe Mentheae; Lamiaceae) is a perennial herb from Korea and China with high ornamental and medicinal value. Here, we report its complete chloroplast genome to provide insight into the phylogenetic relationships of Dracocephalum . The genome is 151,230 bp long, with two inverted repeat regions (25,643 bp each) that separate a large single-copy region (82,536 bp) and a small single-copy region (17,408 bp). It contains 133 genes that encode 88 proteins, eight rRNAs, and 37 tRNAs. The maximum-likelihood phylogenetic analysis strongly supported Dracocephalum monophyly, showing that the genus forms a sister group with the subtribe Menthinae in the tribe Mentheae.
