Characterization of the complete chloroplast genome of a Chinese Endangered species Cymbidium mastersii

Cymbidium mastersii is an endangered species belonging to the first ranking in protection category in China with important ornamental value and breeding value. This study used Illumina high-throughput sequencing technologies for C. mastersii of chloroplast genome sequencing. The genome features of C. mastersii and the phylogenetic relationships were reported and established. The complete chloroplast genome is 156,317 bp in length, consisting of a pair of inverse duplication regions 26,544 bp, a large single-copy region 85,360 bp and a small single-copy region 17,869 bp. The entire genome contains 73 mRNA genes, 30 tRNA genes and 4 rRNA genes. The phylogenetic tree of 23 Orchidaceae species revealed C. mastersii is more closely related to Cymbidium eburneum.
