Characterization of the complete chloroplast genome of Aconitum pendulum (Ranunculaceae), an endemic medicinal herb

Aconitum pendulum is an endemic medicinal herb, which has effects of relieving pains and is widely used to treat frostbite, rheumatoid arthritis, and so on. In this study, we sequenced the complete chloroplast genome with Illumina sequencing technology. The complete chloroplast genome length is 155,597 bp, shows a typical tetrad structure, which manifests as one large and one small single copy (LSC and SSC) regions of 86,336 and 16,961 bp, isolated by two inverted repeat regions (IRs) of 26,150 bp. This study annotated altogether 131 unique genes, consisting of 86 protein-encoding genes, 8 rRNA, and 37 tRNA. According to the maximum likelihood phylogenetic tree based on 20 complete chloroplast genomes, A. pendulum shows close association with additional Aconitum subgenus. The chloroplast genome-wide for A. pendulum would help to conserving the precious natural populations.
