In transgenic and nontransgenic plants, viruses are both initiators and targets of a defense
mechanism that is similar to posttranscriptional gene silencing (PTGS). Recently, it was …

'RNA silencing'is the suppression of gene expression through nucleotide sequence-specific
interactions that are mediated by RNA. Initially identified as an immune system that is …

RNA silencing is described in plants and insects as a defence mechanism against foreign
nucleic acids, such as invading viruses. The RNA silencing-based antiviral defence involves …

RNA silencing is a collective term that refers to diverse RNA-directed processes resulting in
sequence-specific degradation of target RNA and repression of gene expression, either at …

Viral infection in both plant and invertebrate hosts requires a virus-encoded function to block
the RNA silencing antiviral defense. Here, we report the identification and characterization of …

The 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 …

RNA silencing is a powerful tool deployed by plants against viral infection and abnormal
gene expression. Plant viruses have evolved a suite of silencing suppressors for counter …

In plants and some animals, viral infection triggers production of virus-derived short
interfering (si) RNAs (vsRNAs) by the host gene-silencing machinery, which is thought to …

RNA silencing, which is termed post-transcriptional gene silencing in plants, is an RNA
degradation process through sequence-specific nucleotide interactions induced by double …

MicroRNAs (miRNAs) are non-coding RNAs of approximately 20–24 nucleotides in length
that serve as central regulators of eukaryotic gene expression by targeting mRNAs for …
