Abstract

Tripterygium wilfordii is a perennial vine plant with medicinal value and belongs to the family of Celastraceae. In this study, we sequenced and analyzed the complete chloroplast genome of T. wilfordii. The chloroplast genome was 156,700 bp in length with a GC content of 37.47%. It contained two inverted repeat (IR) regions of 26,461 bp; each region was separated by large single-copy and small single-copy regions of 85,409 bp and 18,369 bp, respectively. In total, we annotated 134 unique genes, consisting of 89 protein-encoding genes, 8 rRNAs and 37 tRNAs. Phylogenetic analysis revealed that T. wilfordii was sister to T. regelii in a clade of Tripterygiumii species that was sister to a clade of Euonymus species.

Keywords: Tripterygium wilfordii; complete chloroplast genome; phylogenetic analysis.
