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

In this study, we report the complete plastome sequence of (F.Maek.) Ormerod (Orchidaceae) (NCBI acc. no. KY354041), an endangered plant species protected by the national law of Korea. The gene order and number in the plastome were similar to a typical orchid plastome. The complete plastome was 147,614 bp in length and consisted of a large single copy region of 81,617 bp and a small single copy region of 13,673 bp, separated by two inverted repeats of 26,162 bp. The plastome contained 103 genes, of which 69 were protein-coding genes, 30 were tRNA genes, and four were rRNA genes. Fourteen genes contained one intron and two genes (P and 3) had two introns. The AT content of the plastome was 60.5%. A total of 74 simple sequence repeat regions were identified from the plastome. Phylogenetic analysis determined that was a member of the tribe Cranichideae and revealed the sister group relationship between and within the tribe Cranichideae.
