Progeny of transgenic tobacco plants expressing the cucumber mosaic virus (CMV) coat protein (CP +) or its antisense transcript (antisense-CP) were protected from CMV infection. Symptom development and virus accumulation were reduced or absent in CP + plants, independent of the strength of the inoculum. Antisense-CP plants were protected only at low inoculum concentrations. These results demonstrate that although it is possible to obtain protection in transgenic plants using antisense-CP message, this protection is not as effective as the CP-mediated protection.
