The complete chloroplast genome of an endangered species Cymbidium mastersii (Orchidaceae)

Abstract

Cymbidium mastersii Griff. & Lindl. is an endangered orchid. In this study, we report the complete chloroplast (cp) genome sequence and the cp genome features of C. mastersii. The cp genome sequence of C. mastersii was 155,362 bp in length. It included one large single-copy region (LSC, 84,465 bp), one small single-copy region (SSC, 20,647 bp), and two inverted repeat regions (IRs, 25,125 bp). The cp genome encoded 130 genes, of which 107 were unique genes (80 protein-coding genes, 23 tRNAs, and 4 rRNAs). The maximum-likelihood phylogenetic analysis showed that C. mastersii was a sister of C. erythraeum and C. nanulum.
