The complete chloroplast genome of Cymbidium eburneum (Orchidaceae)

Abstract

Cymbidium eburneum Lindl. is an endangered species of Orchidaceae and distributed in Guangxi, Yunnan and Hainan of China, and India, Myanmar, Nepal, Vietnam. Here, we report the complete chloroplast (cp) genome sequence and the cp genome features of C. eburneum. The complete chloroplast (cp) genome sequence of C. eburneum is 156,520 bp in length and presented a typical quadripartite structure including one large single-copy region (LSC, 85,518 bp), one small single-copy region (SSC, 20,014 bp), and two inverted repeat regions (IRs, 25,471 bp). The cp genome encoded 135 genes, of which 106 were unique genes (78 protein-coding genes, 24 tRNAs, and 4 rRNAs). The phylogenetic relationships show that C. eburneum is closely related to other species in the genus Cymbidium, and is sister with C. tracyanum.
