| Abstract: | Transgenic Nicotiana benthamiana plants expressing the coat protein gene of cymbidium ringspot virus (CyRSV) were tested for resistance against infection with CyRSV. Transgenic plants showed resistance to infection only when the purified virions concentration in the inoculum was as low as 0.05  g/ml. No protection was observed in transgenic plants inoculated with virion concentrations of 0.5 and 5.0 g/ml or when the inoculum was in vitro synthesized genomic RNA. |
