Suppression of RNA silencing by a plant DNA virus satellite requires a host calmodulin-like protein to repress RDR6 expression. [PDF]
PLoS Pathogens, 2014 In plants, RNA silencing plays a key role in antiviral defense. To counteract host defense, plant viruses encode viral suppressors of RNA silencing (VSRs) that target different effector molecules in the RNA silencing pathway.

Acquisition of full-length viral helicase domains by insect retrotransposon-encoded polypeptides
Frontiers in Microbiology, 2015 Recent metagenomic studies in insects identified many sequences unexpectedly closely related to plant virus genes. Here we describe a new example of this kind, insect R1 LINEs with an additional C-terminal domain in their open reading frame 2.

Identification of Silencing Suppressor Protein Encoded by Strawberry Mottle Virus
Frontiers in Plant Science, 2022 Strawberry mottle virus (SMoV) is associated with strawberry decline disease, causing losses to fruit yield and quality. In this study, using a screening system that enables detection of both local and systemic plant host (RNA silencing) defense ...

RNA interference: more than a research tool in the vertebrates' adaptive immunity
Retrovirology, 2005 In recent years, RNA silencing, usage of small double stranded RNAs of ~21 – 25 base pairs to regulate gene expression, has emerged as a powerful research tool to dissect the role of unknown host cell factors in this 'post-genomic' era.

Internuclear gene silencing in Phytophthora infestans is established through chromatin remodelling [PDF]
, 2008 In the plant pathogen Phytophthora infestans, nuclear integration of inf1 transgenic DNA sequences results in internuclear gene silencing of inf1. Although silencing is regulated at the transcriptional level, it also affects transcription from other ...

Influence of viral genes on the cell-to-cell spread of RNA silencing [PDF]
The turnip crinkle virus-based vector TCV–GFPDCP had been devised previously to study cell-to-cell and long-distance spread of virus-induced RNA silencing.

Uirusu, 2008 Small RNAs play a critical role in the regulation of gene expression in diverse cellular processes. This mechanism, termed RNA silencing or RNAi, also functions as a defense mechanism against molecular parasites such as virus and transposon. Whereas RNA silencing is triggered by viral infection, viruses suppress RNA silencing to establish infection ...

Reprogramming of RNA silencing triggered by cucumber mosaic virus infection in Arabidopsis
Genome Biology, 2021 Background RNA silencing has an important role mediating sequence-specific virus resistance in plants. The complex interaction of viruses with RNA silencing involves the loading of viral small interfering RNAs (vsiRNAs) into its host ARGONAUTE (AGO ...
