微滴数字PCR(ddPCR)检测马铃薯S病毒(PVS)
马铃薯(Solanum tuberosum)为世界重要农作物之一,受马铃薯S病毒(Potato virus S,PVS)侵染会导致其品质下降,产量降低;灵敏准确的检测技术将有助于提高PVS的检出率,进而防止其传播扩散危害马铃薯生产,保护马铃薯产业发展。为了建立PVS灵敏准确的检测技术,本研究根据其外壳蛋白(coat protein,CP)基因保守序列设计了微滴数字PCR(droplet digital PCR,ddPCR)的引物探针,并进行了特异性、灵敏度及重复性验证。结果表明,所建立的方法对PVS具有良好的特异性,能够有效区分对照病毒马铃薯X病毒(Potato virus X,PVX)、马铃...

Notes | Potato virus S (PVS), Droplet digital PCR (ddPCR), Detection and identification, Specificity,Sensitivity Potato (Solanum tuberosum) is one of the most important crops in the world and it can be infected by Potato virus S (PVS), which lead to reduction of quality and yield. The high detection rate of PVS, which can be improved by the sensitive and accurate detection technology, will control the PVS threaten for potato production because its introduction and spread is prevented, and the potato industry can be protected. For developing a sensitive and accurate technique, the droplet digital PCR (ddPCR) primers and probe were designed according to the conserved sequence of PVS coat protein (CP) gene and tested through specificity, sensitivity and reproducibility experiment. The results showed that the established method was specific to PVS, and it could effectively distinguish PVS from the control viruses Potato virus X (PVX), Potato virus Y (PVY), Cucumber mosaic virus (CMV) and Tobacco mosaic virus (TMV), which |
