The characteristics of the complete chloroplast genome of <i>Staurogyne concinnula</i> (Hance) O. Kuntze (Acanthaceae)

<i>Staurogyne concinnula</i> (Hance) O. Kuntze (Acanthaceae) is an important ornamental herb mainly distributed in the southern region of China, including Fujian, Guangdong, Hainan, and Taiwan provinces. However, the complete chloroplast genome of <i>S. concinnula</i>, which could serve as a genetic resource for studies on its taxonomy and evolution, is poorly studied at present. In this study, we reported the complete chloroplast genome of <i>S. concinnula</i> that was assembled using high-throughput sequencing data. The chloroplast genome was 153,783 bp long, with a typical quadripartite structure containing a small single-copy region (SSC; 17,855 bp), a large single-copy region (LSC; 84,636 bp) and a pair of inverted repeats (IRs; each 25,646 bp). The overall GC content of the chloroplast genome was 38.04%. A total of 86 protein-coding genes (PCGs), 8 rRNA genes, and 37 tRNA genes were predicted. Phylogenetic analysis based on the combined sequences of 86 PCGs with the other 16 closely related species of Acanthaceae indicated that <i>S. concinnula</i> is closely related to <i>Avicennia marina</i>. The genomic data and finding from the phylogenetic studies of <i>S. concinnula</i> could provide useful information and give light to in-depth studies on the evolution pattern of the understudied species, as well as Staurogyne.
