The complete chloroplast genome sequence of Persicaria perfoliata (L.) H. Gross: a medicinal plant

Abstract Persicaria perfoliata (L.) H. Gross is an herbal medicine with a long history of common use in China. In this study, we sequenced and assembled the complete chloroplast genome sequence of P. perfoliata and investigated its phylogenetic relationship in the family Polygonaceae. The total genome size is 160,585 bp in length with 37.96% GC content, consisting of a small single-copy (SSC) of 12,876 bp, a large single-copy (LSC) of 85,439 bp, and two inverted repeats (IRs) of 31,135 bp. The cp genome contains 128 genes, including 35 tRNA genes, eight rRNA genes, and 85 protein-coding genes. The phylogenetic tree showed that P. perfoliata was closely related to P. maackiana, and Persicaria exhibited a closer relationship with Bistorta in the family Polygonaceae. This work provides a molecular basis for investigating the evolutionary status, phylogenetic relationships, and population genetics of this species.
