Characterization of the complete chloroplast genome of Angelica dahurica (Apiaceae) as an herb in China

Angelica dahurica is an upright perennial herb that is becoming more and more fashionable in the garden in the world. The complete chloroplast genome of A. dahurica was annotated and studied in this paper. It was a circular molecular genome with a size of 146,918 bp in length, which was composed of four distinct regions such as a large single-copy region of 93,605 bp, a small single-copy region of 17,669 bp and a pair of IR regions of 17,822 bp. We annotated and found comprised 129 genes, including 85 protein-coding genes (PCGs), 36 transfer RNA genes (tRNAs) and eight ribosome RNA genes (rRNAs). The overall nucleotide composition is A of 30.8%, T of 31.7%, C of 19.1% and G of 18.4%, with a total A + T content of the chloroplast genome 62.5% and G + C of 37.5%. Phylogenetic analysis with the reported chloroplast genomes revealed that A. dahurica is most closely related to Angelica gigas in the phylogenetic relationships.
