Till now, phylogenetic relationships between <i>A. ernestii</i> and other closely related species remain unclear. In this study, we first characterized the complete chloroplast (cp) genome of <i>A. ernestii</i>. The whole cp genome was 121,841 bp in size, including one hundred and thirteen genes. Results of comparative cp genome revealed that only <i>ycf</i>1 and <i>ycf</i>2 was characterized by a considerable variation. Our phylogenetic analyses supported the monophyly of the genus <i>Abies</i> and revealed a clear separation between <i>A. ernestii</i> and <i>A. chensiensis</i> Tiegh. This study highlights the significance of using cp genomes to examine species boundaries among closely related fir species.Mitochondrial DNA.
