摘要： Strawberry mottle virus (SMoV) is one of the main RNA viruses that profoundly affects the growth of strawberries worldwide. The rapid on-site detection of SMoV described here can be applied to produce virus-free strawberry seedlings. Reverse transcriptase recombinase polymerase amplification (RT-RPA) was combined with lateral flow (LF) strip to rapidly detect SMoV. The detection limit was 500 fg of RNA under optimized conditions. The SMoV-RT-RPA-LF assay was optimal with a combination of 2 mu L reverse primer (5 mu M) and 0.6 mu L probe (10 mu M) in a 50 mu L RT-RPA reaction mixture for isothermal amplification at 40 degrees C for 15 min. In addition, 100 suspected samples were collected from different regions in the Shanghai suburbs. The SMoV-RT-RPA-LF assay showed that 3 of these 100 samples were positive for SMoV, which was in good concordance with the reverse transcription polymerase chain reaction (RT-PCR) results. The primers and probe had a unique specificity to SMoV because there was no cross-reaction with other strawberry viruses. This study provides an effective technique for the rapid on-site detection of SMoV to ensure a virus-free strawberry nursery.
