The complete chloroplast genome of Cymbidium erythraeum (Orchidaceae)

Abstract

Cymbidium erythraeum Lindl. is an endangered species of Orchidaceae and distributed in China and Bhutan, India, Myanmar, Nepal, and Vietnam. Here, we report the complete chloroplast (cp) genome sequence and the cp genome features of C. erythraeum. The complete chloroplast (cp) genome sequence of C. erythraeum is 156,327 bp in length and including one large single-copy region (LSC, 85,404 bp), one small single-copy region (SSC, 20,021 bp), and two inverted repeat regions (IRs, 25,426 bp). The cp genome encoded 136 genes, of which 107 were unique genes (80 protein-coding genes, 23 tRNAs, and four rRNAs). The phylogenetic relationships show that C. erythraeum is closely related to other species in the genus Cymbidium and is sister with C. tracyanum.
