The complete chloroplast genome of Mahonia oiwakensis (Berberidaceae), a traditional Chinese medicinal plant

Mahonia oiwakensis is a frequently-used traditional Chinese medicinal plant with efficient anti-tumor and anti-inflammatory ability. In this study, we assembled the complete chloroplast (cp) genome of M. oiwakensis. The complete cp genome of M. oiwakensis is 165,126 bp in length, and has a typical structure with large (LSC 73,382 bp) and small (SSC 18,644 bp) single-copy regions separated by a pair of inverted repeats (IRs 36,550 bp) of large size. The M. oiwakensis cp genome contains 148 genes, of which 103 protein-coding genes, 37 tRNA genes, 8 rRNA genes. Phylogenetic analysis shows that M. oiwakensis closely clustered with Mahonia bealei, but were nested among three speices of Berberis, which robustly supports that Mahonia is not monophyletic, thus needs redefinition.
