Abstract

Styrax odoratissimus Champ. ex Benth., also known as the extraordinary aromatic plant of Styracaceae, has been seriously threatened due to human activities. In this study, the complete chloroplast (cp) genome sequence of S. odoratissimus was determined by applying next-generation sequencing. The entire cp genome was determined to be 157,921 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 87,524 bp and 18,301 bp, respectively, which were separated by a pair of 26,048 bp inverted repeat (IR) regions. The genome contained 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of S. odoratissimus genome is 36.96% and the corresponding values in LSC, SSC, and IR regions are 34.80, 30.27, and 42.92%, respectively. A phylogenetic tree reconstructed by 31 chloroplast genomes reveals that S. odoratissimus is most related to Styrax grandiflorus Griffith.

Keywords: Styracaceae; Styrax odoratissimus; complete chloroplast genome; phylogenetic analysis.
