Abstract

Dendrobium is one of the largest genera in Orchidaceae with approximately 1500 species. Many of them have been used as Traditional Chinese Medicine (TCM) for hundreds of years. Here, the first complete chloroplast genome sequence of D. densiflorum was reported and characterized. The complete cpDNA of D. densiflorum is a circular molecule of 153,122 bp, which contains 76 protein-coding genes, 30 tRNA genes, and four rRNA genes. Our phylogenetic analysis indicated that the newly sequenced cpDNA of D. densiflorum could be used for the phylogenetic study of Dendrobium species.

Keywords: Australasian clade; Dendrobium densiflorum; chloroplast genome; phylogeny.
