Characterization of the complete chloroplast genome of Coelogyne fimbriata (Orchidaceae).

ABSTRACT: Coelogyne fimbriata has been classified as a national second-class protected orchid species in China. In this study, we report and characterize the complete chloroplast (cp) genome sequence of C. fimbriata in an effort to provide genomic resources useful for promoting its conservation and systematic research. The complete genome is 159,010 bp in length and the overall GC content is 43.3%. The cp genome sequence has a typical quadripartite structure, comprising two inverted repeats (IRA and IRB) regions, which are separated by a small single-copy (SSC) region and a large single-copy (LSC) region. Moreover, a total of 135 functional genes were annotated, including 89 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The phylogenetic analysis recovered a close relationship between C. fimbriata and Pleione formosana, and both species are placed within the tribe Arethuseae (Orchidaceae).
