The complete chloroplast genome of Pleione hookeriana (Orchidaceae) from Yunnan Province, China

Pleione hookeriana (Lindl.) B. S. Williams is a species of Orchidaceae with high ornamental value. It is a protected plant in China. To document the genetic history of this rare species, the chloroplast genome sequence of P. hookeriana from the Yunnan Province, China, were analyzed. The complete chloroplast genome is 158,930 bp in length and contains a large single-copy (LSC) region of 86,880 bp, a small single-copy region of 18,664 bp (SSC), and a pair of inverted repeats (IR) of 26,693bp. There are 137 genes, including 89 protein-coding, 40 transfer RNA (tRNA) and 8 ribosomal RNA (rRNA) genes. The total GC content of the chloroplast genome sequence is 37.2%. The maximum-likelihood phylogenetic analysis indicated that P. hookeriana was sister to P. chunii (MK792342.1). The result may be because the species are roughly the same geographical location and advanced and developed from the same ancestor. This study provides important information for the identification and conservation of species, and genetic engineering of P. hookeriana.
