RNA virus genomes hybridize to cellular rRNAs and to each other.

RESUMO
In this communication we show that the RNA genomes of vesicular stomatitis, Sindbis, and reoviruses can specifically hybridize under stringent conditions to the large rRNAs present in HeLa cell cytoplasmic extracts. In addition, we show that some virus genome RNAs can also hybridize to each other. On the basis of our previous detailed studies identifying specific regions of hybridization between the poliovirus genome and 28S rRNA, we suggest that a similar phenomenon of "patchy complementary" may be responsible for the interactions described here (M. A. McClure and J. Perrault, Nucleic Acids Res. 13:6797-6816, 1985). The possible biological implications of these cross-reacting hybridizations and practical considerations in the use of viral probes for diagnosis are discussed.
