Abstract

Dendrobium christyanum H.G. Reichenbach (Orchidaceae) is used as a source of the Chinese traditional medicine. Here, we report that the complete chloroplast (cp) genome sequence of D. christyanum is 157972 bp in length with134 genes, of which 114 are unique genes (80 protein-coding genes, 30 tRNAs, and 4 rRNAs). Phylogenetic analysis indicated that D. christyanum was closely related to D. strongylanthum, and D. longicornu. The newly sequenced cp genome will be useful for the phylogenetic and genetic conservation studies of Dendrobium.

Keywords: Dendrobium christyanum; Orchidaceae; chloroplast genome; phylogeny.
