The complete chloroplast genome of var. (Dryadoideae, Rosaceae) and phylogenetic analysis.

L. var. (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 var. 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 var. was sister to the clade of Amygdaloideae. This study contributes fundamental insights into the cp genome of var. , which will have expanded its use in photosynthesis and evolutionary study.
