Characterization of the complete chloroplast genome of Leycesteria formosa wall. (Caprifoliaceae), a medicinal plant in southwest China

Leycesteria formosa is a frequently used medicinal plant (namely, ‘Yi yao’) in Southwest China. In this study, we sequenced the complete chloroplast (cp) genome sequence of L. formosa to investigate its phylogenetic relationship in the family Caprifoliaceae. The chloroplast genome of L. formosa was 156,261 bp in length with 38.1% overall GC content, including a large single-copy (LSC) region of 90,353 bp, a small single-copy (SSC) region of 19,299 bp and a pair of inverted repeats (IRs) of 23,287 bp. The cp genome contained 112 genes, including 79 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated Leycesteria was closely related to the genus Triosteum or Heptacodium.
