The complete chloroplast genome and phylogenetic analysis of <i>Persicaria jucunda</i> (Meisn.) Migo (Polygonaceae)

<i>Persicaria jucunda</i> is a plant distributed at meadow or wetland. Our study reports the complete chloroplast genome. The chloroplast genome of <i>P. jucunda</i> 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 <i>P. jucunda</i> 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 <i>P. foliosa</i> and <i>P. kawagoeana</i> among the species analyzed. The chloroplast genome provides a valuable genetic resource for phylogenetic studies.
