摘要: 根据PVY、PVS和PLRV外壳蛋白(Coat protein,CP)基因序列的保守区域设计各自的引物,利用三重RT-PCR技术实现了在同一反应体系中同时扩增出3种病毒产物。PVY、PVS和PLRV扩增产物测序长度均与目的片段的长度相符,分别为781,181,364 bp;各种病毒产物的测序结果同GeneBank中的序列比对后的同源性均高达95%以上。将3种病毒的RNA稀释后进行RT-PCR,PVY、PVS和PLRV的最低检测含量分别为4.5 pg/μL~4.5 fg/μL、3.7fg/μL和4.6 fg/μL。三重RT-PCR为检测单独或复合感染PVY、PVS和PLRV的马铃薯材料,提供了一种方便、高效的分子学方法。

Abstract: Three pairs of primers for PVY,PVS and PLRV,by comparing and finding out each conserved domain of CP sequence were designed,and then triplex-RT-PCR technology was used to amplify three product fragments of PVY,PVS and PLRV in one reaction simultaneously.The length of the PVY,PVS and PLRV are fit to the length of target DNA,781,181,364 bp respectively.The homology of the three viruses all reach up to 95% by comparing sequencing result with each published sequences in GeneBank respectively.After diluting the RNA samples,the minimum detection content for PVY,PVS and PLRV is 4.5 pg/μL-4.5 fg/μL,3.7 fg/μL and 4.6 fg/μL in RT-PCR respectively.Triplex-RT-PCR technology provides one convenient and high-efficiency molecular method to detect potato materials infected with one or more viruses among PVY,PVS and PLRV.
