The complete chloroplast genome of Codonopsis tsinglingensis (Campanulaceae), an endemic Chinese medicine species in Qinling mountains

Codonopsis tsinglingensis, belonging to the Campanulaceae family, is a perennial medicinal herb highly valued in Chinese traditional medicine. The complete chloroplast genome of C. tsinglingensis was sequenced using the Illumina Hiseq 4000 platform. The size of the C. tsinglingensis chloroplast genome is 170,253 bp, with an average GC content of 38.3%. This circular molecule has a typical quadripartite structure containing a large single copy (LSC) region of 85,408 bp, a small single copy (SSC) region of 8179 bp, and two inverted (IRs) repeat regions of 38,333 bp. The genome contains 138 genes, including 92 protein-coding genes, 38 transfer RNA genes (tRNA), 8 ribosomal RNA genes (rRNA). Phylogenetic analysis based on complete chloroplast genome sequences of 14 species indicates that C. tsinglingensisis closely related to Codonopsis minima in the Campanulaceae family.
