| 中文摘要:目的 建立快速、便捷、准确的南沙参及其混伪品特异性DNA特征序列（DSS）标记分子鉴定方法。方法 采用植物叶绿体基因组数据库（CGIR）获取叶绿体基因组序列，采用IdenDSS软件获得待测物种DSS组及其特异性引物对，通过DNA提取、聚合酶链式反应扩增、测序、序列比对验证，检测待测样品的基因组中是否含有目标物种的DSS或其反向互补序列，进行基原鉴定。结果 通过对筛选的5对DSS与南沙参及其混伪品序列的比对验证，最终确定1组可用于南沙参基原鉴定的DSS标记引物，并将该序列上传至中药分子鉴定平台标准数据库中，结合数据库的BLAST功能，可实现南沙参基原的快速、准确鉴定。结论 筛选的DSS标记特异性强、准确度高，可用于南沙参的基原鉴定。 |

| Abstract:Objective To develop a rapid, simple, and accurate molecular identification method based on DNA signature sequence (DSS) for distinguishing Adenophorae Radix from its adulterants.Methods The Chloroplast Genome Information Resource (CGIR) was used to obtain chloroplast genome sequences, and IdenDSS was employed to screen for DSS and specific primers of the original plants of Adenophorae Radix. DNA extraction, PCR amplification, sequencing, and sequence alignment were then carried out to examine whether the genomic DNA of the sample to be detected contained DSS or the reverse complementary sequence of the target species.Results After comparison of the selected 5 DSSs for Adenophorae Radix and its adulterants, the DSS and primers that can be used for the identification of Adenophorae Radix were finally determined. The DSS was uploaded to the Traditional Chinese Medicine Molecular Identification Platform. The combination of DSS with BLAST achieved rapid and accurate identification of the original plant of Adenophorae Radix.Conclusion The DSS selected had strong specificity and high accuracy and could be effectively applied in the identification of the original plant of Adenophorae Radix. |
