The chloroplast genome of Gardenia jasminoides and related phylogenetic analysis (Rubiaceae)

Abstract

Gardenia jasminoides is well distributed and planted in China because of high ornamental and medical applications in Rubiaceae. Therefore, aiming at studying the biodiversity and solar-related genes, we acquired its complete chloroplast genome. The chloroplast genome was 155,096 bp in length with typical circle structure, it presented an 85,409 bp large single-copy (LSC) region, an 18,103 bp small single-copy (SSC) region, and two 25,792 bp inverted repeat (IRs) regions. The overall GC content was 37.49%, SSC and IR components showed extreme GC percentages ranging from 31.53 to 43.18. A brief online annotation reported 125 CDSs, 8 rRNAs, and 33 tRNA. To our surprise, G. jasminoides was closer to Coffea canephora and Coffea arabica within Rubiaceae from phylogenetic analysis. This chloroplast genome announcement of the G. jasminoides could embody light on the artificial breeding and further researches in the genus Gardenia Ellis and recruit more studies in this family.
