The complete chloroplast genome sequence of the medicinal plant Strophanthus divaricatus (Lour.) Hook. & Arn. (1837) and its phylogenetic analysis

Strophanthus divaricatus (Lour.) Hook. & Arn. (1837) is an important medicinal plant utilized in traditional Chinese and Yao ethnomedicine. Here, we report its complete chloroplast genome based on Illumina sequencing. The circular genome is 155,409 bp in length, with an overall GC content of 38.28%, and displays a typical quadripartite structure comprising a large single-copy region (85,683 bp), a small single-copy region (18,182 bp), and two inverted repeats (25,772 bp each). A total of 130 genes were annotated, including 85 protein-coding genes, 37 tRNAs, and 8 rRNAs. Phylogenetic analysis revealed that S. divaricatus is closely related to S. wallichii.
