The complete chloroplast genome of Aconitum piepunense (Ranunculaceae) and its phylogenetic analysis

Abstract

Aconitum piepunense belonging to the family Ranunculaceae is an endangered herb species in southwestern China. In this study, the complete chloroplast genome of A. piepunense was sequenced, and the results revealed a typical quadripartite structure with a length of 155,836 bp, including a large single-copy region (LSC, 86,433 bp), a small single-copy region (SSC, 16,945 bp), and a pair of inverted repeat (IR) regions (IRa and IRb, 26,229 bp, respectively). A total of 130 genes were identified in the A. piepunense chloroplast genome, containing 85 protein-coding genes, 37 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. Phylogenetic analysis based on the maximum likelihood method indicated that A. piepunense formed a monophyletic group, which was sister to A. contortum and A. vilmorinianum.
