| Abstract: | To develop a rapid,sensitive and specific droplet digital RT-PCR assay for quantitative detection of arabis mosaic virus(ArMV),the primers and probe were designed based on the conserved sequence of ArMV coat protein gene.The specificity,sensitivity and reproducibility of the developed method for ArMV detection were determined.The results showed that the specificity of the developed method was high and there was no crossing reaction with control viruses.The sensitivity of the method was 0.56 copies/μL.The coefficient of variation was 0.74%,indicating the established digital RT-PCR method had good reproducibility.The method developed in this study was suitable for rapid and quantitative detecting ArMV in practical samples. |
