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 …

Many scientists, if not all, feel that their particular plant virus should appear in any list of the
most important plant viruses. However, to our knowledge, no such list exists. The aim of this …

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 …

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) …

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 …

Plants are invaded by an array of pathogens of which only a few succeed in causing
disease. The attack by others is countered by a sophisticated immune system possessed by …

A multitude of small RNAs (sRNAs, 18–25 nt in length) accumulate in plant tissues. Although
heterogeneous in size, sequence, genomic distribution, biogenesis, and action, most of …

ABSTRACT RNA interference (RNAi) is a process of eukaryotic posttranscriptional gene
silencing that functions in antiviral immunity in plants, nematodes, and insects. However …

Like metazoans, plants use small regulatory RNA s (sRNA s) to direct gene expression.
Several classes of sRNA s, which are distinguished by their origin and biogenesis, exist in …

Plant RNA silencing machinery enlists four primary classes of proteins to achieve sequence-
specific regulation of gene expression and mount an antiviral defense. These include Dicer …
