The complete chloroplast genome of Diels (Apioideae), a traditional medicinal herb in China.

Heracleum hemsleyanum Diels is a traditional medicinal herb in China. We reported its first complete chloroplast genome. The chloroplast genome was 146,775 bp in length with 37.53% GC content, containing a large single copy region (LSC, 93,309 bp), a small single copy region (SSC, 17,502 bp), and a pair of inverted repeat regions (IRs, 17,982 bp). Moreover, the chloroplast genome encoded 130 genes, including 86 protein-coding genes (PCGs), 36 transfer RNA genes (tRNAs), and eight ribosomal RNA genes (rRNAs). Phylogenetic analysis indicated that H. hemsleyanum was closely related to Heracleum moellendorffii and Heracleum yungningense. This assembled chloroplast genome will provide vital information on the genetic resources, phylogenetic relationships, and the species identification of the genus .
