Size Selective Recognition of siRNA by an RNA Silencing Suppressor [PDF]

open access: yes, 2003
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.

Tomato Spotted Wilt Virus NSs Protein Supports Infection and Systemic Movement of a Potyvirus and Is a Symptom Determinant

open access: yesViruses, 2018
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.

Supervised learning classification models for prediction of plant virus encoded RNA silencing suppressors. [PDF]

open access: yesPLoS ONE, 2014
Viral encoded RNA silencing suppressor proteins interfere with the host RNA silencing machinery, facilitating viral infection by evading host immunity.

Two Classes of Silencing RNAs Move between Caenorhabditis elegans Tissues [PDF]

open access: yes, 2013
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]

open access: yes, 2016
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 in Drosophila

open access: yesACTA HISTOCHEMICA ET CYTOCHEMICA, 2003
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

open access: yes, 2009
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.

Multiple Domains of the Tobacco mosaic virus p126 Protein Can Independently Suppress Local and Systemic RNA Silencing

open access: yesMolecular Plant-Microbe Interactions, 2012
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]

open access: yes, 2010
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 ...

RNA-Spray-Mediated Silencing of Fusarium graminearum AGO and DCL Genes Improve Barley Disease Resistance

open access: yesFrontiers in Plant Science, 2020
Over the last decade, several studies have revealed the enormous potential of RNA-silencing strategies as a potential alternative to conventional pesticides for plant protection.
