The complete chloroplast genome of Coreopsis lanceolata L. and its phylogenetic analysis.

Coreopsis lanceolata L. 1753 is a perennial herb of the family Asteraceae, often cultivated as an ornamental flower. The species has also been reported to contain a wide range of phytochemicals and to exhibit diverse pharmacological activities. To better understand the genetic information of C. lanceolata, its complete chloroplast genome was assembled and characterized for the first time in this study. The chloroplast genome was 150,448 bp long and contained 129 genes, including 86 protein-coding genes, 35 tRNA genes, and eight rRNA genes. A rearrangement involving double inversions was observed in the chloroplast genome when compared with that of Barnadesia caryophylla. Phylogenomic analysis indicated that C. lanceolata, Bidens frondosa, B. tripartita, and B. pilosa formed a monophyletic clade. The findings of this study provide support for future research on the evolution and potential pharmaceutical applications of this species.
