The complete chloroplast genome of <i>Gardenia stenophylla</i> Merr (Rubiaceae) and its phylogenetic analysis

<i>Gardenia stenophylla</i> Merr, a member of the genus <i>Gardenia</i> in the family Rubiaceae, possesses significant medicinal and ornamental value and is widely distributed in China. This study reports the newly sequenced chloroplast genome of <i>Gardenia stenophylla</i> Merr. The complete chloroplast genome of <i>Gardenia stenophylla</i> Merr (155,109 bp, GC content of 37.5%) was shown to have a typical quadripartite structure, containing a pair of inverted repeat regions (IRs) of 28,802 bp separated by a large single-copy (LSC) region of 85,396 bp and a small single-copy (SSC) region of 18,109 bp. The chloroplast genome contained 151 genes encoding 106 proteins, 37 tRNAs, and eight rRNAs. The <i>Gardenia stenophylla</i> Merr chloroplast genome displayed the closest phylogenetic relationship to <i>Gardenia jasminoides</i> and <i>Gardenia jasminoides</i> var. grandiflora. These data will assist in future molecular phylogenetics of the Rubiaceae.
