Sequences and structures required for recombination between virus-associated RNAs.

Abstract excerpt

RNA recombination has been described for a number of viruses in the plant and animal kingdoms, but the mechanisms of selection of recombination sites are poorly understood. The nonrandom recombination between two subviral RNAs associated with turnip crinkle virus was used to study the requirement for specific sequences and structures in the generation of recombinant molecules. Single-base mutations that disrupted...
