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

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 , 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 . Phylogenomic analysis indicated that , , , and formed a monophyletic clade. The findings of this study provide support for future research on the evolution and potential pharmaceutical applications of this species.
