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.
长白瑞香变种（L. var. (Nakai) Nakai 1918）是一种矮小灌木，主要生长在北半球的高山和北极地区，是亚洲的一个特有变种。在本研究中，首次对长白瑞香变种的完整叶绿体（cp）基因组进行了表征，并用于系统发育分析。该cp基因组跨度为158,271 bp，总体GC含量为36.5%。共鉴定出129个基因，包括84个蛋白质编码基因（PCG）、37个tRNA基因和8个rRNA基因。此外，在该物种中检测到了重复序列和微卫星。涉及蔷薇科39个cp基因组的系统发育分析表明，长白瑞香变种是桃亚科分支的姐妹群。本研究为长白瑞香变种的cp基因组提供了基本见解，这将扩大其在光合作用和进化研究中的应用。
