Specificity (A) and sensitivity (B) analyses of IC-RT-PCR for RDV detection. (A) Specificity analysis of IC-RT-PCR for RDV detection. Lane M was 1 kb DNA marker. Lane 1 was a viruliferous leafhopper. Lanes 2–6 were RDV-, SRBSDV-, RBSDV-, RRSV- or RSV-infected rice plants, respectively. Lane 7 was a healthy rice plant. Lanes 8 and 9 were non-viruliferous leafhoppers. (B) Sensitivity analysis of IC-RT-PCR for RDV detection in rice. Lane M was 1 kb DNA marker; Lanes 2–16 were RDV-infected rice tissue crude extracts at twofold serial dilutions from 1:80 to 1:1,310,720 (w/v, g mL−1); Lane 1 was a RDV-infected rice as a positive control and lane CK− was a healthy rice as a negative control. (C) Sensitivity analysis of IC-RT-PCR for RDV detection in insect vector. Lanes 2–16 were viruliferous leafhopper tissue crude extracts at serial twofold dilutions from 1:400 to 1:6,553,600 (individual leafhopper/μL). Lane 1 was a viruliferous leafhopper as a positive control and lane CK− was a non-viruliferous leafhopper as a negative control.
