Abstract
Cymbidium mannii 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 to sequence and analyze the complete chloroplast genome of C. mannii. The genome features of C. mannii and the phylogenetic relationships among Orchidaceae species were reported and established. The complete chloroplast genome is 152,544 bp in length, consisting of a pair of inverse duplication regions 25,357 bp, a large single-copy region 86,014 bp and a small single-copy region 15,816 bp. The entire genome contains 74 mRNA genes, 30 tRNA genes and 4 rRNA genes. The phylogenetic tree of 23 Orchidaceae species revealed C. mannii is more closely related to Cymbidium aloifolium.
