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 …

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 …

Citrus tristeza virus (CTV)(genus Closterovirus, family Closteroviridae) is the causal agent of
devastating epidemics that changed the course of the citrus industry. Adapted to replicate in …

Cucumber mosaic virus (CMV) is an important virus because of its agricultural impact in the
Mediterranean Basin and worldwide, and also as a model for understanding plant–virus …

We investigated the genetic pathway in Arabidopsis thaliana targeted during infection by
cucumber mosaic virus (CMV) 2b protein, known to suppress non-cell-autonomous …

Plant roots are required for the acquisition of water and nutrients, for responses to abiotic
and biotic signals in the soil, and to anchor the plant in the ground. Controlling plant root …

MicroRNAs (miRNAs) regulate gene expression posttranscriptionally through RNA
silencing, a mechanism conserved in eukaryotes. Prevailing models entail most animal …

The helper component-proteinase (HC-Pro) protein of potyviruses is a suppressor of gene
silencing and has been shown to elicit plant developmental-defect-like symptoms. In …

The Cucumber mosaic virus (CMV) 2b counter-defense protein disrupts plant antiviral
mechanisms mediated by RNA silencing and salicylic acid (SA). We used microarrays to …

Induced mechanisms are by definition imperceptible or less active in uninfected, unstressed,
or untreated plants, but can be activated by pathogen infection, stress, or chemical treatment …
