In order to develop a novel system for the discrimination of five ginseng cultivars (Panax ginseng Meyer), single nucleotide polymorphism (SNP) genotyping assays with real-time polymerase chain reaction were conducted. Nucleotide substitution in gDNA library clones of P. ginseng cv. Yunpoong was targeted for the SNP genotyping assay. From these SNP sites, a set of modified SNP specific fluorescence probes (PGP74, PGP110, and PGP130) and novel primer sets have been developed to distinguish among five ginseng cultivars. The combination of the SNP type of the five cultivars, Chungpoong, Yunpoong, Gopoong, Kumpoong, and Sunpoong, was identified as 'ATA', 'GCC', 'GTA', 'GCA', and 'ACC', respectively. This study represents the first report of the identification of ginseng cultivars by fluorescence probes. An SNP genotyping assay using fluorescence probes could prove useful for the identification of ginseng cultivars and ginseng seed management systems and guarantee the purity of ginseng seed.
为了开发一种鉴别五种人参品种(Panax ginseng Meyer)的新系统,我们进行了实时聚合酶链反应的单核苷酸多态性(SNP)基因分型检测。我们针对人参 cv. Yunpoong 的 gDNA 文库克隆中的核苷酸取代设计了 SNP 基因分型检测。从这些 SNP 位点中,我们开发了一组改良的 SNP 特异性荧光探针(PGP74、PGP110 和 PGP130)和新的引物对,以区分五种人参品种。五个品种(Chungpoong、Yunpoong、Gopoong、Kumpoong 和 Sunpoong)的 SNP 类型分别被鉴定为 'ATA'、'GCC'、'GTA'、'GCA' 和 'ACC'。本研究首次报道了利用荧光探针鉴定人参品种。使用荧光探针的 SNP 基因分型检测可用于鉴定人参品种和人参种子管理系统,并保证人参种子的纯度。
