Viral Suppressors of RNA Silencing
Current Opinion in Biotechnology, 2001The suppression of RNA silencing by plant viruses represents a viral adaptation to a novel host antiviral defense. Three types of viral suppressors have been identified through the use of a variety of silencing suppression assays. The first two types of suppressor are capable of a complete or partial reversal of pre-existing RNA silencing; the third ...

Plant Viral Suppressors of RNA Silencing
Virus Research, 2004RNA silencing is an ancient eukaryotic pathway in which double stranded RNA (dsRNA) triggers destruction of related RNAs in the cell. Early studies in plants pointed to a role for this pathway as a defense against viruses. Most known plant viruses have RNA genomes and replicate via dsRNA intermediates, thereby serving as potent inducers of RNA ...

Viral suppressors of RNA silencing
Trends in Plant Science, 2011The infection and replication of viruses in the host induce diverse mechanisms for combating viral infection. One of the best-studied antiviral defence mechanisms is based on RNA silencing. Consistently, several viral suppressors of RNA silencing (VSRs) have been identified from almost all plant virus genera, which are surprisingly diverse within and ...

AtRLI2 is an Endogenous Suppressor of RNA Silencing
Plant Molecular Biology, 2006RNA silencing is a mechanism involved in gene regulation during development and anti-viral defense in plants and animals. Although many viral suppressors of this mechanism have been described up to now, this is not the case for endogenous suppressors.

RNA-silencing suppressors of geminiviruses
Journal of General Plant Pathology, 2008Geminiviruses are single-stranded (ss) DNA viruses that not only cause devastating diseases of important food and fiber crops worldwide, but also are important models to study fundamental aspects of virus-induced gene silencing and RNA interference.
