Chloroplast Genome of the Dragonhead Herb, Dracocephalum heterophyllum

We performed multiple sequence alignments using the cp genome of 22 species and constructed the Maximum Likelihood (ML) and Bayesian trees, and found that D. heterophyllum were more closely related to D. moldavica and D. palmatum. In addition, the phylogenetic relationships between Dracocephalum and other members of Lamiaceae were consistent with previous results. These results are valuable for further formulating effective strategies of conservation and management for species of Dracocephalum, as well as providing a foundation for future research on the genetic resources of Dracocephalum.
