| 摘 要： | 本研究建立了一种基于Taqman-MGB探针的亚稀褶红菇Russula subnigricans实时荧光定量PCR检测方法。根据亚稀褶红菇与其近似种的内转录间隔区（internal transcribed spacers,ITS）序列差异,设计合成1对引物和1条特异性Taqman-MGB探针,并用常见有毒红菇种类进行验证。结果显示,引物特异性良好,仅亚稀褶红菇出现荧光信号,完成整个检测过程只需2h。该法能够为毒蘑菇中毒的快速检测提供技术支持。

| Abstract: | A method for detection of Russula subnigricans was established based on Taqman-MGB probe of real-time fluorescent quantitative PCR. A pair of primers and a Taqman-MGB probe were designed and synthesized according to the ITS sequences of R. subnigricans and its related species, and the common toxic Russula species were used for verification. The results showed that the primers had good specificity, and only R. subnigricans exhibited fluorescence signal. It just took 2h to complete the whole detection process. It was indicated that this method could provide a technical support for rapid detection of toxic mushroom poisoning. |
