Abstract
Conium maculatum L. (1753) is a toxic biennial plant in the Apiaceae family. It is native to Europe and North Africa and is listed as an invasive species in China. Its 153,090 bp chloroplast genome has 132 genes (37 tRNA genes, 8 rRNA genes, and 87 protein-coding genes), structured into 2 IRs (25,087 bp), one LSC (85,716 bp) and one SSC(17,200 bp), with 37.52% GC content. Phylogenetically, it is closest to Angelica sinensis, Trachydium subnudum, Glehnia littoralis, Heracleum hemsleyanum, Peucedanum praeruptorum, and Saposhnikovia divaricata. These findings support genetic preservation of the species and Coniumphylogenetic study.
