| Zusammenfassung: | A real-time fluorescent reverse-transcriptase polymerase chain reaction (RT-PCR) assay using a short fluorogenic 3' minor groove binder (MGB) DNA hydrolysis probe was developed for the detection of Prunus necrotic ringspot virus (PNRSV) in stone fruit trees. The covalent attachment of the minor groove binder moiety at the 3' end of the probe increased the probe target duplex stability and raised the melting temperature to a range suitable for real-time analysis. The real-time RT-PCR assay correlated well with conventional RT-PCR results for the detection of PNRSV. This assay reliably detects PNRSV in bark tissues of dormant cherry and plum trees. Furthermore, it is well adapted for the routine detection of PNRSV because it eliminates one risk of contamination by performing the whole test in a single closed tube. This system may replace the commonly used diagnostic techniques (e.g., woody indicators and immunological tests) to detect this virus |
