The Complete Chloroplast Genome Sequence Of Cypripedium Tibeticum King Ex Rolfe (Orchidaceae)

In this study, we determined the complete chloroplast genome of Cypripedium tibeticum, an endangered species in China. The plastome is 159,223bp in length, with a large single-copy region (LSC) of 86,537bp, a small single-copy region (SSC) of 17,552bp, and a pair of inverted repeat regions (IRs) of 27,567bp each. It contains 133 genes, including 87 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The overall GC content was 36.9%, while the corresponding values in the LSC, SSC, and IR regions are 34.6, 30.4, and 42.6%, respectively. The phylogenetic analysis showed that C. tibeticum was closely related to its congeners and the classification of five subfamilies of Orchidaceae was also highly supported.
