aNumber of days elapsed between inoculation and the appearance of symptoms.
bNumber of infected plants/number of inoculated plants, verified by visual observation of symptoms and confirmed by RCA following digestion with component-specific restriction enzymes. The total number of inoculated plants represents two independent experiments.
cValues in italics indicate the low detection of ToSRV components when inoculated simultaneously with ToRMV components.
