The complete chloroplast genome sequence of Habenaria dentata (Orchidaceae).

Habenaria dentata is a rare species with high ornamental value in China. In this study, we report the complete chloroplast (cp) genome of H. dentata using the Illumina sequencing data. The total genome of H. dentata is 153,682 bp in length and the GC content is 36.62%, with a pair of inverted repeats (IRs) regions of 26,339 bp each, a large single-copy (LSC) region of 83,963 bp and a small single-copy (SSC) region of 17,041 bp. The cp genome encoded 133 genes, including 87 protein-coding genes (PCG), eight rRNA genes, and 38 tRNA genes. The maximum-likelihood phylogenetic analysis based on 12 cp genomes showed that H. dentata was sister to Habenaria chejuensis and Habenaria ciliolaris. This work will be valuable for genetic and phylogenetic studies on H. dentata.
