RNA silencing is a homology-dependent gene inactivation mechanism that regulates a wide
range of biological processes including antiviral defense. To deal with host antiviral …

MicroRNAs (miRNAs) are small RNAs that control gene expression through silencing of
target mRNAs. Mature miRNAs are processed from primary miRNA transcripts by the …

The family Geminiviridae is one of the largest and most important families of plant viruses.
The small, single-stranded DNA genomes of geminiviruses encode 5–7 proteins that …

RNA silencing is a central regulator of gene expression in most eukaryotes and acts both at
the transcriptional level through DNA methylation and at the post-transcriptional level …

Viruses cause epidemics on all major cultures of agronomic importance, representing a
serious threat to global food security. As strict intracellular pathogens, they cannot be …

In eukaryotic RNA-based antiviral immunity, viral double-stranded RNA is recognized as a
pathogen-associated molecular pattern and processed into small interfering RNAs (siRNAs) …

MicroRNAs are a class of non-coding small RNAs involved in the negative regulation of
gene expression, which play critical roles in developmental and metabolic pathways …

Begomoviruses are numerous and geographically widespread viruses that cause
devastating diseases in many crops. Monopartite begomoviruses are frequently associated …

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 …

The mechanisms underlying induction and suppression of RNA silencing in the ongoing
plant-virus arms race are poorly understood. We show here that virus-derived small RNAs …
