The complete chloroplast genome of <i>Coreopsis lanceolata</i> L. and its phylogenetic analysis

<i>Coreopsis lanceolata</i> 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 <i>C. lanceolata</i>, 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 <i>Barnadesia caryophylla</i>. Phylogenomic analysis indicated that <i>C. lanceolata</i>, <i>Bidens frondosa</i>, <i>B. tripartita</i>, and <i>B. pilosa</i> formed a monophyletic clade. The findings of this study provide support for future research on the evolution and potential pharmaceutical applications of this species.
