The complete plastome sequence of Datisca cannabina L. (Datiscaceae, Cucurbitales)

Abstract

AbstractIn this study, we report the first complete plastome sequence of Datisca cannabina (GenBank acc. no. OP432690). The plastome had a typical quadripartite structure. Its size was 162,914 bp, consisting of 90,890 bp large single-copy (LSC), 19,296 bp small single-copy (SSC), and 26,364 bp inverted repeat (IR) regions. It contained 112 genes, including 78 protein-coding, 30 tRNA, and four rRNA genes. The infA gene was pseudogenized. Sixteen genes contain one intron and two genes (clpP and ycf3) had two introns. Our phylogenetic tree showed that D. cannabina formed a close relationship with Begoniaceae. However, further samples are required to determine the phylogenetic placement of Datiscaceae in Cucurbitales.
