Figure 3. Quantification of ORMV infection and PR1 gene expression. Steady-state mRNA level of ORMV coat protein (A) and PR1 mRNA (B) was done as described in methods section. Ct, control non-exposed plants; ct-ORMV, ORMV-infected tissue of control plants; ct-distal, non-infected tissue of ORMV-infected control plants; UV-ORMV, ORMV-infected tissues of plants previously exposed to UV; UV-distal, non-infected tissue of ORMV-infected plants previously exposed to UV; BS-ORMV, ORMV-infected tissue of bystander plants; BS-distal, non-infected tissue of ORMV-infected bystander plants. Different letters indicated significantly different data points (p < 0.05).
