Figure 1. Symptoms elicited 14 days after the inoculation on Nicotiana clevelandii plants by the Rs-CMV and mutated Rs2-2a777 CMV virus (A).

Northern blot hybridization analysis of total RNAs extracted from non-inoculated leaves 6 weeks after inoculation (B). The radiolabeled probe was specific for Rs-CMV RNA3. Ethidium bromide-stained rRNA from the same volume of each sample is shown below each lane.
