The complete chloroplast genome of Gardenia stenophylla Merr (Rubiaceae) and its phylogenetic analysis

Abstract

Gardenia stenophylla Merr, a member of the genus Gardenia 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 Gardenia stenophylla Merr. The complete chloroplast genome of Gardenia stenophylla 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 Gardenia stenophylla Merr chloroplast genome displayed the closest phylogenetic relationship to Gardenia jasminoides and Gardenia jasminoides var. grandiflora. These data will assist in future molecular phylogenetics of the Rubiaceae.
