Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) Inhibits RNA-Mediated Gene Silencing by Targeting Ago-2

Viruses, 2015
Porcine reproductive and respiratory syndrome virus (PRRSV) infection strongly modulates the host’s immune response. The RNA silencing pathway is an intracellular innate response to viral infections.

Transcriptome Profiling Reveals a Petunia Transcription Factor, PhCOL4, Contributing to Antiviral RNA Silencing

Frontiers in Plant Science, 2022
RNA silencing is a common antiviral mechanism in eukaryotic organisms. However, the transcriptional regulatory mechanism that controls the RNA silencing process remains elusive.

RNA silencing in plants [PDF]

The Biochemist, 2004
There are at least three RNA silencing pathways for silencing specific genes in plants. In these pathways, silencing signals can be amplified and transmitted between cells, and may even be self-regulated by feedback mechanisms. Diverse biological roles of these pathways have been established, including defence against viruses, regulation of gene ...

Analysis of Pineapple Mealybug Wilt Associated Virus -1 and -2 for Potential RNA Silencing Suppressors and Pathogenicity Factors

Viruses, 2015
Higher plants use RNA silencing to defend against viral infections. As a counter defense, plant viruses have evolved proteins that suppress RNA silencing.

Simultaneous Suppression of Two Distinct Serotonin N-Acetyltransferase Isogenes by RNA Interference Leads to Severe Decreases in Melatonin and Accelerated Seed Deterioration in Rice

Biomolecules, 2020
Serotonin N-acetyltransferase (SNAT) is the penultimate enzyme in the melatonin biosynthetic pathway, in which serotonin is converted into N-acetylserotonin (NAS) in plants.

Analysis of Tospovirus NSs Proteins in Suppression of Systemic Silencing. [PDF]

PLoS ONE, 2015
RNA silencing is a sequence-specific gene regulation mechanism that in plants also acts antiviral. In order to counteract antiviral RNA silencing, viruses have evolved RNA silencing suppressors (RSS).

Secondary siRNAs in Plants: Biosynthesis, Various Functions, and Applications in Virology

Frontiers in Plant Science, 2021
The major components of RNA silencing include both transitive and systemic small RNAs, which are technically called secondary sRNAs. Double-stranded RNAs trigger systemic silencing pathways to negatively regulate gene expression.

Viral suppression of RNA silencing [PDF]

Science China Life Sciences, 2012
يلعب إسكات الجينات (إسكات الحمض النووي الريبي) دورًا أساسيًا في الدفاع المضاد للفيروسات في النباتات والفطريات واللافقاريات. تقوم الفيروسات بتشفير البروتينات التي تمنع إسكات الجينات لمواجهة دفاع المضيف. تم تحديد المثبطات الفيروسية لإسكات الحمض النووي الريبي (RSVs) من جميع الفيروسات النباتية تقريبًا التي تولد وبعض فيروسات الحشرات والثدييات. كشفت الدراسات

Identification of Pns6, a putative movement protein of RRSV, as a silencing suppressor

Virology Journal, 2010
RNA silencing is a potent antiviral response in plants. As a counterdefense, most plant and some animal viruses encode RNA silencing suppressors. In this study, we showed that Pns6, a putative movement protein of Rice ragged stunt virus (RRSV), exhibited

Viruses and 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 ...
