The complete chloroplast genome sequence of Aconitum tschangbaischanense (Ranunculaceae)

Abstract

The perennial herbal medicine species Aconitum tschangbaischanense, is endemic to Changhai Mountain, Jilin province. In this study, we attempted to uncover the complete chloroplast (cp) genome of A. tschangbaischanense based on sequencing data using the Illumina sequencing technology. As per the results: (1) the length of its complete cp genome is 155,881 bp with a typical tetrad structure; (2) the structure of its cp genome contains large single-copy and small single-copy (LSC and SSC) regions of 86,351 and 16,9444 bp, respectively, isolated by two inverted repeat regions (IRs) of 26,293 bp; (3) we annotated a total 131 genes, consisting of 86 protein-coding genes, eight rRNA genes, and 37 tRNA genes. According to the maximum-likelihood phylogenetic tree based on complete cp genomes, A. tschangbaischanense, showed close association with A. carmichaelii, which belongs to clade I. Finally, this study provides the characteristics of the cp genome of A. tschangbaischanense, and its phylogenetic position.
