Abstract
Persicaria jucunda is a plant distributed at meadow or wetland. Our study reports the complete chloroplast genome. The chloroplast genome of P. jucunda is a typical tetrameric structure with a total length of 159,843 bp, containing a large single-copy (LSC) region of 84,350 bp, a small single-copy (SSC) region of 13,151 bp, and two inverted repeat regions (IRs) of 31,171 bp. The total GC content was 38.2%, 36.5% for the LSC region, 33.2% for the SSC region, and 41.5% for the IR region. The P. jucunda chloroplast genome contains 128 genes, including 83 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis based on 36 chloroplast genomes showed similarity to P. foliosa and P. kawagoeana among the species analyzed. The chloroplast genome provides a valuable genetic resource for phylogenetic studies.
