Abstract:
We report the complete chloroplast genome sequence of Gynostemma pentaphyllum, a well-known traditional Chinese medicine, which produces triterpenoid saponins similar to Panax ginseng. The assembled chloroplast genome (cpDNA) was 157,654 bp in length and structurally divided into four distinct regions, namely, large single copy region (86,794 bp), small single copy region (18,654 bp) and a pair of inverted repeat regions (26,103 bp). A total of 143 genes were annotated, including 87 protein-coding genes, 10 tRNA genes and 46 rRNA genes. Phylogenetic analysis revealed that the chloroplast genome sequence of G. pentaphyllum is most closely related to Cucumis melo.
