FIGURE 2.

Length of detection of PCR and RPA to detect different concentrations. (A) Different concentrations amplified by RPA. (M1) DL2000 Plus DNA Marker. (1–8) The plasmid with N segment of the TSWV were serially diluted 10-fold (2.26 × 108 to 2.26 × 101 copies/μl). (9) Negative control has RNase-free water as an input. (B) Different concentrations only amplified by the PCR reaction. (M2) DL2000 Plus DNA Marker. (1–8) The plasmid with N segment of the TSWV were serially diluted 10-fold (2.26 × 108 to 2.26 × 101 copies/μl). (9) Negative control has RNase-free water as an input. RPA, recombinant polymerase amplification.
