| Abstract: | The mechanism of satellite RNA (Sat-RNA) mediated attenuation of virus disease was suggested to be the result of competition between satellite RNAs and their helper viral RNAs for replication. Subcellular distribution of viral coat protein in cucumber mosaic virus (CMV) infected leaf tissues shows that the presence of Sat-RNAs interferes with the movement of CMV coat protein into chloroplants. As a strategy for controlling virus diseases, the expression of Sat-RNAs in transgenic plants confers some extent of resistance that may not be strong enough to protect the plants from natural virus infections. Transgenic plants expressing both the Sat-RNA and the coat protein of CMV exhibit enhanced resistance to the virus. |
