The Sharka disease caused by the
Plum pox virus (PPV) is the most important virosis in stone fruit production. To prevent the spread of this virus reliable detection methods are required. Existing techniques are time consuming, laborious, costly, insensitive and/or require sophisticated technical equipment. To resolve these drawbacks, cascade rolling circle amplification (CRCA) and loop mediated isothermal amplification (LAMP) were examined for their applicability for the detection of PPV. CRCA proved to be insufficient. In contrast, LAMP allowed for reverse transcription of PPV RNA, DNA amplification and visualisation of DNA synthesis in a single reaction at a constant temperature. A fast extraction procedure simplified the sample preparation. The accuracy, the specificity, the sensitivity and the simplicity of this method regarding the high-throughput monitoring of PPV infection but also for subgroup differentiation was demonstrated.
