The complete chloroplast genome and phylogenetic analysis of <i>Ophiorrhiza guizhouensis</i> (Rubiaceae), a folk medicinal plant from the Wuling Mountain region

<i>Ophiorrhiza guizhouensis</i> has not had its complete chloroplast genome reported, which limits our understanding of its genetics and evolution. In this study, we assembled and annotated its chloroplast genome, revealing a circular structure with 80 protein-coding genes (GenBank accession number: PX023271). The total length of the genome was found to be 154,134 bp, and its GC content was 37.76%. Phylogenetic analysis confirmed that <i>Ophiorrhiza guizhouensis</i> belonged to the genus <i>Ophiorrhiza</i> (subfamily Rubioideae, Rubiaceae) and exhibited the closest phylogenetic affinity to <i>Ophiorrhiza densa</i>. These findings provide valuable genomic resources for in-depth studies on <i>Ophiorrhiza</i> and the Rubiaceae family, including genetic diversity analysis and phylogenetic research.
