What is Complete chloroplast genome sequences of the medicinal plant Aconitum transsectum (Ranunculaceae): comparative analysis and phylogenetic relationships about?

Abstract Background Aconitum transsectum Diels. (Ranunculaceae) is an important medicinal plant that is widely used in traditional Chinese medicine, but its morphological traits make it difficult to recognize from other Aconitum species. No research has sequenced the chloroplast genome of A.transsectum, despite the fact that phylogenetic analysis based on chloroplast genome sequences provides essential evidence for plant classification. Results In this study, the chloroplast (cp) genome of A. transsectum was sequenced, assembled, and annotated. A. transsectum cp genome is a 155,872 bp tetrameric structure including a large single copy (LSC, 87,671 bp) and a small single copy (SSC, 18,891 bp) section, as well as a pair of inverted repeat sequences (IRa and IRb, 25,894 bp each). 131 genes are encoded by the complete cp genome, comprising 86 protein-coding genes, 37 tRNAs, and 8 rRNAs. The most favored codon in the A. transsectum cp genome is AUG, and 46 repeats and 241 SSRs were also identified. The A. transsectum cp genome is similar in size, gene composition, and IR expansion and contraction to the cp genomes of seven Ranunculaceae species. Phylogenetic analysis of cp genomes of 28
