RNA recombination in animal and plant viruses.

RNA recombination in animal and plant viruses.

An increasing number of animal and plant viruses have been shown to undergo RNA-RNA recombination, which is defined as the exchange of genetic information between nonsegmented RNAs. Only some of these viruses have been shown to undergo recombination in experimental infection of tissue culture, animals, and plants. However, a survey of viral RNA structure and sequences suggests that many RNA vir...

Recombination in large RNA viruses: Coronaviruses

Coronaviruses contain a very large RNA genome, which undergoes recombination at a very high frequency of nearly 25% for the entire genome. Recombination has been demonstrated to occur between viral genomes and between defective-interfering (DI) RNAs and viral RNA. It provides an evolutionary tool for both viral RNAs and DI RNA and may account for the diversity in the genomic structure of corona...

Homologous Recombination in Negative Sense RNA Viruses

Recombination is an important process that influences biological evolution at many different levels. More and more homologous recombination events have been reported among negative sense RNA viruses recently. While sporadic authentic examples indicate that homologous recombination does occur, recombination seems to be generally rare or even absent in most negative sense RNA viruses, and most of...
