Abstract
- Bupleurum sikangense is an endemic species to China distributed in Xizang (Tibet), which has high saikosaponin content and potential medicinal value. Morphologically, it extremely resembles B. commelynoideum. In order to get a better understanding of the relationship between B. sikangense and B. commelynoideum, and on the phylogenetic status of the two species in the genus, the complete chloroplast (cp) genomes of them were sequenced. The genome organization, repeat sequences, codon usage, RNA-editing sites, and variation of their cp genomes revealed high similarity between the species. Some highly variable regions like trnK-UUU_rps16, rps16_trnQ-UUG, ndhC_trnV-UAC, petA_psbJ, accD_psaI, and petL_psbE were identified, providing potential molecular markers for differentiating the two species. Phylogenetic analysis indicated that B. commelynoideum has a closer relationship to B. chinese than that to B. sikangense. Overall, this study will not only improve our knowledge about cp genomes of these two species, and but also provide data for further research on species identification, safe medical application, conservation genetics, etc., of Bupleurum plants.
