The complete chloroplast genome sequence of Heracleum millefolium

We assembled the complete chloroplast genome of Heracleum millefolium which is a traditional widely used medicinal plant in China. The whole genome is 150,025 bp in length which was divided into four subregions: a large single-copy region (93,645 bp), a pair of 19,458 bp inverted repeats regions, and a small single-copy region (17,464 bp), respectively. Additionally, the chloroplast genome of H. millefolium detected 128 genes, including 85 protein coding genes, 36 transfer RNAs, and eight ribosomal RNAs. The overall GC content of this cp genome is 37.5% and the coverage value is 151,950. Phylogenetic analysis based on 17 chloroplast genomes dataset was conducted to clarify the relationships of the major clades in Apiaceae. The results strongly supported the monophyly of Heracleum and the closer relationship of H. millefolium and H. candicans.
