Symptom expression and DNA accumulation in test plants. Plant phenotypes [A] radish, N. benthamiana and tomato seedling following inoculation with a RaLCV DNA-A (RLA) and CYVMV-[IN:Pat:Rad:08] DNA-A (CRA)were inoculated either alone or with RaLCV DNA-betasatellites (RLβ) and CYVMV-[IN:Pat:Rad:08] betasatellites (CRβ). The photographs were taken at 30 dpi and southern blot analysis showing relative accumulation of viral DNA in inoculated [B-C] radish, [D] N. benthamiana (left panel)and [E] tomato (right panel) plants.
