The complete chloroplast genome of <i>Dryas octopetala</i> var. <i>asiatica</i> (Dryadoideae, Rosaceae) and phylogenetic analysis

<i>Dryas octopetala</i> L. var. <i>asiatica</i> (Nakai) Nakai 1918 is a dwarf shrub that mainly grow in alpine and arctic zones of the Northern Hemisphere, representing an endemic variety in Asia. In the present study, the complete chloroplast (cp) genome of <i>D. octopetala</i> var. <i>asiatica</i> was first characterized and used for its phylogenetic analysis. The cp genome span 158,271 bp with an overall GC content of 36.5%. A total of 129 genes were identified, including 84 protein-coding genes (PCGs), 37 tRNA genes, and 8 rRNA genes. In addition, repetitive sequences and microsatellites were detected within this species. Phylogenetic analysis involving 39 cp genomes from Rosaceae family indicated that <i>D. octopetala</i> var. <i>asiatica</i> was sister to the clade of Amygdaloideae. This study contributes fundamental insights into the cp genome of <i>Dryas octopetala</i> var. <i>asiatica</i>, which will have expanded its use in photosynthesis and evolutionary study.
