Abstract
The complete chloroplast (cp) genome sequence of Ajania pacifica, called as golden and silver chrysanthemum, was newly analyzed in this study. It was 151,059 bp in length and was a typical circular structure composed of and comprised of a large single copy region (82,857 bp) and a small single copy region (18,294 bp) which were separated by two inverted repeat regions (24,954 bp). The molecular phylogenetic analyses of A. pacifica and its related taxa was conducted based on the complete chloroplast genome sequences, and it was proved that the genus Ajania is embedded in the genus Chrysanthemum clade as well as a monotypic genus Opisthopappus. In the other hand, the genus Artemisia was divided into two group in the tribe Anthemideae.
