The RNA Polymerase II-associated factor 1 complex represses small-RNA-mediated heterochromatin formation and gene silencing [PDF]

, 2015
RNAi interference (RNAi) is a highly conserved regulatory mechanism employed by almost all Eukaryotes. With RNAi organisms can modulate the expression of endogenous genes and protect the integrity and identity of their genomes.

Transcriptional Gene Silencing (TGS) via the RNAi Machinery in HIV-1 Infections

Biology, 2012
Gene silencing via non-coding RNA, such as siRNA and miRNA, can occur at the transcriptional, post-transcriptional, and translational stages of expression.

Transcriptional and post-transcriptional regulation of RNAi-related gene expression during plant-virus interactions

Stress Biology, 2022
As sessile organisms, plants encounter diverse invasions from pathogens including viruses. To survive and thrive, plants have evolved multilayered defense mechanisms to combat virus infection.

Splayed : a chromatin remodeler regulating tissue specific gene silencing and developmental timing [PDF]

, 2014
A number of mechanisms that contribute to epigenetic regulation of gene expression have been described in plants. The concert actions of these mechanisms contribute to proper patterning of gene expression within organs and tissues, therefore insuring ...

Factors influencing Barley Stripe Mosaic Virus-mediated gene silencing in wheat [PDF]

, 2010
Virus induced gene silencing (VIGS) is a technology that has been used primarily to target the virus genome in infected plants. However, if the virus genome carries inserts derived from the host plant, the system could be employed to target the mRNAs ...

The convergence of autophagy, small RNA and the stress response – implications for transgenerational epigenetic inheritance in plants

Biomolecular Concepts, 2014
Recent discoveries in eukaryotes have shown that autophagy-mediated degradation of DICER and ARGONAUTE (AGO), the proteins involved in post-transcriptional gene silencing (PTGS), can occur in response to viral infection and starvation.

Functional Analysis of Cotton Leaf Curl Kokhran Virus/Cotton Leaf Curl Multan Betasatellite RNA Silencing Suppressors

Biology, 2015
In South Asia, Cotton leaf curl disease (CLCuD) is caused by a complex of phylogenetically-related begomovirus species and a specific betasatellite, Cotton leaf curl Multan betasatellite (CLCuMuB).

RNA-interference components are dispensable for transcriptional silencing of the drosophila bithorax-complex.

PLoS ONE, 2013
BackgroundBeyond their role in post-transcriptional gene silencing, Dicer and Argonaute, two components of the RNA interference (RNAi) machinery, were shown to be involved in epigenetic regulation of centromeric heterochromatin and transcriptional gene ...
