The complete plastome sequence of the endangered orchid (Orchidaceae).

In this study, we report the complete chloroplast sequence of (Maxim.) Makino (Orchidaceae) (NCBI acc. no. KX871235), which is an endangered plant species currently protected by the National Law of Korea. The gene order and content of the plastome are similar to those of a typical orchid plastome. The 11 genes are pseudogenized or lost completely from the plastome of The plastome contains 102 genes, of which 68 are protein-coding genes, 30 and four are transfer RNA (tRNA) and ribosomal RNA (rRNA) genes, respectively. Sixteen genes contain one intron and two genes (P and 3) have two introns. The complete plastome is 142,996 bp long and consists of one large and small single copy each of 81,669 and 10,969 bp, respectively, separated by two inverted repeats of 25,179 bp. The AT content of the plastome is 62.6%. Sixty-five simple sequence repeat (SSR) loci, consisting of 56 mono-SSR, seven di-SSR, and two tri-SSR are scattered along the plastome. Some of these plastome SSR loci may be useful for developing genetic markers for the populations. Phylogenetic analysis has shown that is a member of the Malaxideae. The genus forms a monophyletic clade with .
