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 …

The majority of positive-strand RNA viruses of plants replicate and selectively encapsidate
their progeny genomes into stable virions in cytoplasmic compartments of the cell where the …

We have performed a systematic search for recombination in the region encoding coat
protein and the 3′ non-translated region in natural isolates of potyviruses, the largest group …

New viral diseases are emerging continuously. Viruses adapt to new environments at
astounding rates. Genetic variability of viruses jeopardizes vaccine efficacy. For many …

Transfer RNA-like structures (TLSs) that are sophisticated functional mimics of tRNAs are
found at the 3′-termini of the genomes of a number of plant positive strand RNA viruses …

RNA-RNA recombination is thought to occur preferentially at certain selected sites and in
only a few RNA viruses; the mechanism for these restrictions is unknown. In this paper we …

Recombination in RNA viruses involves the exchange of genetic information between two
nonsegmented RNA genomes, as distinct from the reassortment of RNA seen in viruses …

Ongoing characterization of cis-acting sequences in bromovirus RNA-dependent RNA
replication and transcription has been complemented in the past year by progress in …

tRNAs, the adapter molecules in protein synthesis, also serve as metabolic cofactors and as
primers for viral RNA-directed DNA synthesis. The genomic and subgenomic RNAs of some …

The structurally and functionally best known RNA molecule is undoubtedly transfer RNA
(tRNA). tRNA owes its name to the central role it performs in protein biosynthesis: it mediates …
