The complete chloroplast genomes of persicaria hydropiper and P. pubescens (polygonaceae).

Persicaria hydropiper (L.) Spach and P. pubescens (Blume) Hara (Polygonaceae) are widely used as traditional Chinese medicinal plants. In this study, the complete chloroplast (cp) genomes of P. hydropiper and P. pubescens were sequenced, assembled, and annotated. The cp genome sizes of P. hydropiper and P. pubescens are 159,054 bp and 159,502 bp, respectively. The cp genomes of P. hydropiper and P. pubescens each contain a total of 130 genes, including 86 protein-coding, 37 tRNA, and 8 rRNA genes. Phylogenetic analysis reveals that P. hydropiper is close to P. pubescens and P. japonica, and Persicaria is mostly closely related to Bistorta.
