Mitochondrial DNA B Resour. 2022 Jul 22;7(7):1326-1328. doi: 10.1080/23802359.2022.2097489. eCollection 2022.

ABSTRACT

Diarthron tianschanicum (Pobedimova) Kit Tan (Thymelaeaceae), a perennial herb, has been used as counterfeit for Stellera chamaejasme in traditional Chinese folk medicine. In this study, the complete chloroplast genome sequence of D. tianschanicum is reported for the first time. The plastome, 172,119 bp in length, is quadripartite and circular. It contains a large single-copy (LSC) region (85,829 bp), a small single-copy (SSC) region (2828 bp), and two separate inverted repeat (IR) regions (41,731 bp). The overall GC content of the complete chloroplast genome is 36.8%. The genome contains 139 genes, including 93 protein-coding, 38 tRNA genes, and eight rRNA genes. The phylogenetic tree showed that all sampled species of Thymelaeaceae formed a monophyletic clade. D. tianschanicum was closely related to the congeneric D. linifolium and formed a monophyly with 100% support.
