The complete chloroplast genome of Schisandra repanda (Siebold & Zucc.) Radlk. (Schisandraceae)

The complete chloroplast genome of Schisandra repanda (Siebold & Zucc.) Radlk., 1886, was assembled and annotated for the first time using NGS data. The genome is 146,620 bp in length and consists of a large single-copy (LSC) region of 95,338 bp, a small single-copy (SSC) region of 18,330 bp, and two inverted-repeat (IR) regions of 16,476 bp each. A total of 125 genes were annotated, including 82 protein-coding genes, 8 rRNA genes, and 35 tRNA genes. These results provide fundamental genomic information for species identification, comparative studies of Schisandra, and climate change response relevant to conservation.本研究首次利用下一代测序（Next Generation Sequencing, NGS）数据，完成了重瓣五味子（Schisandra repanda (Siebold & Zucc.) Radlk., 1886）完整叶绿体基因组的组装与注释。该基因组全长146620 bp，包含1个长单拷贝（Large Single-Copy, LSC）区域（长度95338 bp）、1个短单拷贝（Small Single-Copy, SSC）区域（长度18330 bp），以及2个反向重复（Inverted-Repeat, IR）区域，每个区域长度为16476 bp。共注释得到125个功能基因，其中包括82个蛋白质编码基因、8个核糖体RNA（rRNA）基因以及35个转运RNA（tRNA）基因。本研究结果可为物种鉴定、五味子属植物比较基因组学研究以及与物种保护相关的气候变化响应研究提供基础基因组学数据。
