The complete chloroplast genome of Holarrhena pubescens and its phylogenetic analysis

Abstract

Holarrhena pubescens Wall. ex G. Don, 1837 is an important medicinal plant belonging to the Holarrhena genus in the Apocynaceae family. In this study, the complete chloroplast (cp) genome sequence of H. pubescens was sequenced using the Illumina NovaSeq platform. The cp genome of H. pubescens was 160,108 bp in length with 37.21% overall GC content. The cp genome of H. pubescens containing a large single-copy region (LSC, 88,685 bp), a small single-copy region (SSC, 18,671 bp), and a pair of inverted repeat regions (SSC, 26,376 bp). The cp genome encoded 129 genes, including 84 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis based on complete protein coding genes sequences revealed that H. pubescens was closest to Beaumontia murtonii.
