Complete chloroplast genome of <i>Petrocosmea qinlingensis</i> (Gesneriaceae), a protected wild plant in the Qinling mountains

<i>Petrocosmea qinlingensis</i> is a protected wild plant endemic in China, inhabiting low-light limestone cliffs but the complete chloroplast genome has not been reported. In this study, we first sequenced and assembled the complete chloroplast genome of <i>P. qinlingensis</i>. The total size of this genome was 153,865 bp, including a large single-copy (LSC) region (84,737 bp), a small single-copy (SSC) region (18,244 bp), and two inverted repeats (IRs) regions (25,442 bp). This genome encoded 111 uniquegenes, consisted of 77 protein-coding genes, four ribosomal RNA genes, and 30 transfer RNA genes. Phylogenomic analysis based on the chloroplast protein-coding genes and showed that the genus <i>Petrocosmea</i> was the closest relative to <i>Raphiocarpus</i>. Our results will support further phylogeographic, population genetic studies of this species.
