The complete chloroplast genome sequence of Pholidota articulata (Orchidaceae), a rarely medicinal orchid

Pholidota Lindl. ex Hook. was placed in tribe Arethuseae Lindl. (Epidendroideae, Orchidaceae), while its generic relationship has been unclear. Since the plastid genome could play a key role in plant systematics, the complete chloroplast (cp) genome of P. articulata was reported in this paper. The cp genome was 160,114 bp in length with four typical quadripartite structures, which was consisted of a large single copy (LSC) region of 87,756 bp, a small single copy (SSC) region of 18,872 bp, and two inverted repeats (IR) of 26,734 bp. In addition, the cp genome encoded 132 genes in total, of which were 113 unique genes, including 79 protein-coding genes, 30 tRNAs, and 4 rRNAs. The phylogenetic analysis indicated that P. articulata was closely clustered with other two species of Pholidota and that they appeared to be related to Pleione in Arethuseae Lindl.
