Size Selective Recognition of siRNA by an RNA Silencing Suppressor [PDF]
RNA silencing in plants likely exists as a defense mechanism against molecular parasites such as RNA viruses, retrotransposons, and transgenes. As a result, many plant viruses have adapted mechanisms to evade and suppress gene silencing.

Plant viruses are inducers and targets of antiviral RNA silencing. To condition susceptibility, most plant viruses encode silencing suppressor proteins that interfere with antiviral RNA silencing.

Two Classes of Silencing RNAs Move between Caenorhabditis elegans Tissues [PDF]
Organism-wide RNA interference (RNAi) is due to the transport of mobile silencing RNA throughout the organism, but the identities of these mobile RNA species in animals are unknown. Here, we present genetic evidence that both the initial double-stranded

Molecular Mechanism of DNA Topoisomerase I-Dependent rDNA Silencing: Sir2p Recruitment at Ribosomal Genes [PDF]
Saccharomyces cerevisiae sir2Δ or top1Δ mutants exhibit similar phenotypes involving ribosomal DNA, including (i) loss of transcriptional silencing, resulting in non-coding RNA hyperproduction from cryptic RNA polymerase II promoters; (ii) alterations ...

RNA silencing is a highly conserved mechanism found in both the plant and animal kingdoms that is thought to protect the genome from disruption by transposons and viral integration events. Double stranded RNAs (dsRNA) produced by transposons or replicating virus result in the production of short 21-25 nucleotide double stranded RNA molecules containing

RNA Silencing: An Antiviral Mechanism
RNA silencing is an evolutionarily conserved sequence-specific gene-inactivation system that also functions as an antiviral mechanism in higher plants and insects. To overcome antiviral RNA silencing, viruses express silencing-suppressor proteins which can counteract the host silencing-based antiviral process.

Small RNA-mediated RNA silencing is a widespread antiviral mechanism in plants and other organisms. Many viruses encode suppressors of RNA silencing for counter-defense.

Factors influencing Barley Stripe Mosaic Virus-mediated gene silencing in wheat [PDF]
Virus induced gene silencing (VIGS) is a technology that has been used primarily to target the virus genome in infected plants. However, if the virus genome carries inserts derived from the host plant, the system could be employed to target the mRNAs ...
