Abstract

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

Dryas octopetala var. asiatica（Dryadoideae，蔷薇科）的完整叶绿体基因组及系统发育分析。

Dryas octopetala L. var. asiatica (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，是亚洲特有的品种。本研究首次鉴定了八仙花变种的完整叶绿体（cp）基因组，并将其用于系统发育分析。cp 基因组跨度为 158,271 bp，总 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（PCGs）、37 个 tRNA 基因和 8 个 rRNA 基因。此外，在该物种中还发现了重复序列和微卫星。涉及蔷薇科 39 个 cp 基因组的系统进化分析表明，D. octopetala var.这项研究有助于从根本上了解八月茄的 cp 基因组，从而扩大其在光合作用和进化研究中的应用。
