摘要： Strawberry mild yellow edge virus (SMYEV) is a latent virus that severely affects the yield and quality of strawberry fruit. The technology suitable for rapid and accurate detection of SMYEV on site is important to effectively control its spread. In this study, a reverse transcription recombinase polymerase amplification combined with lateral flow strip (SMYEV-RT-RPA-LF), targeting the conserved genome of Beijing SMYEV isolate, was established to diagnose SMYEV in strawberries. The SMYEV-RT-RPA-LF assay showed no cross-reaction with other strawberry viruses. The sensitivity of SMYEV-RT-RPA-L assay was 100 times higher than that of RT-PCR (10 pg/mu L). In addition, through the detection of suspected samples in the field, it was found that the accuracy of SMYEV-RT-RPA-L assay was consistent with the RT-PCR results. However, compared with RT-PCR, SMYEV-RT-RPA-LF assay has the advantages of simple operation, time savings, and high specificity and sensitivity, indicating the potential application of SMYEV-RT-RPA-LF in the rapid field diagnosis of SMYEV.
