The complete chloroplast genome of Coelogyne barbata (Orchidaceae), a rare and ornamental orchid

Abstract

The genus of Coelogyne Lindl. comprised about 200 species while its generic relationship has been uncertain. The whole chloroplast genome of C. barbata was reported in order to provide new data on the molecular phylogeny of Coelogyne. The cp genome of C. barbata was 1,600,93 bp in total length, including a pair of inverted repeat regions (IR, 26,710 bp), one large single-copy region (LSC, 87,868 bp), and one small single-copy region (SSC, 188,05 bp). The complete chloroplast DNA encoded 132 genes, containing 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Phylogenetic analysis showed that C. barbata was related to Pholidota imbricata.
