Characterization and genetic analysis of the complete chloroplast genome of Schisandra chinensis (Magnoliaceae: Schisandra), an herbal medicine from China.


ABSTRACT: Schisandra chinensis is a deciduous woody vine plant that has been used in traditional medicine for thousands of years in China. In this study, we researched the complete chloroplast genome of S. chinensis. The complete chloroplast genome length is 147,779?bp, containing a large single-copy region (LSC) of 97,352bp, a small single-copy region (SSC) of 20,313?bp, and a pair of inverted repeat (IR) regions of 15,057?bp. The overall nucleotide composition is: A of 29.8%, T of 30.8%, C of 20.2%, and G of 19.2%, with a total GC-content of the chloroplast genome 39.4% and AT of 60.6%. Whole chloroplast genome of S. chinensis contains 126 genes, including 83 protein-coding genes (PCG), 35 transfer RNA (tRNAs) genes, and 8 ribosome RNA (rRNAs) genes. Phylogenetic and genetic analysis based on 30 herbal species confirmed the position of S. chinensis closely related to S. sphenanthera. The complete chloroplast genome of S. chinensis provides more molecular data for the genetic diversity and genetic evolutionary relationship of this species in China.
