Tertiary siRNAs mediate paramutation in C. elegans. [PDF]

open access: yesPLoS Genetics, 2015
In the nematode Caenorhabditis elegans, different small RNA-dependent gene silencing mechanisms act in the germline to initiate transgenerational gene silencing. Piwi-interacting RNAs (piRNAs) can initiate transposon and gene silencing by acting upstream

Functional Genomic Screening Reveals Splicing of the EWS-FLI1 Fusion Transcript as a Vulnerability in Ewing Sarcoma

open access: yesCell Reports, 2016
Ewing sarcoma cells depend on the EWS-FLI1 fusion transcription factor for cell survival. Using an assay of EWS-FLI1 activity and genome-wide RNAi screening, we have identified proteins required for the processing of the EWS-FLI1 pre-mRNA.

Identification and Characterization of miRNA Transcriptome in Asiatic Cotton (Gossypium arboreum) Using High Throughput Sequencing

open access: yesFrontiers in Plant Science, 2017
MicroRNAs (miRNAs) are small 20–24nt molecules that have been well studied over the past decade due to their important regulatory roles in different cellular processes.

Potato spindle tuber viroid as Inducer of RNA Silencing in Infected Tomato

open access: yesMolecular Plant-Microbe Interactions, 2001
Potato spindle tuber viroid (PSTVd), an RNA plant pathogen encoding no known proteins, induces systemic symptoms on tomato plants. We report detection of small RNAs of approximately 25 nucleotides with sequence specificity to PSTVd in infected plants: an

Epigenetic silencing in transgenic plants

open access: yesFrontiers in Plant Science, 2015
Epigenetic silencing is a natural phenomenon in which the expression of gene is regulated through modifications of DNA, RNA or histone proteins. It is a mechanism for defending host genomes against the effects of transposable element, viral infection and

Secondary siRNAs in Plants: Biosynthesis, Various Functions, and Applications in Virology

open access: yesFrontiers in Plant Science, 2021
The major components of RNA silencing include both transitive and systemic small RNAs, which are technically called secondary sRNAs. Double-stranded RNAs trigger systemic silencing pathways to negatively regulate gene expression.

Titration and hysteresis in epigenetic chromatin silencing [PDF]

open access: yes2013 Phys. Biol. 10 036005, 2012
Epigenetic mechanisms of silencing via heritable chromatin modifications play a major role in gene regulation and cell fate specification. We consider a model of epigenetic chromatin silencing in budding yeast and study the bifurcation diagram and characterize the bistable and the monostable regimes.

Virus‐Induced Gene Silencing, a Post Transcriptional Gene Silencing Method [PDF]

open access: yesInternational Journal of Plant Genomics, 2009
Virus‐induced gene silencing (VIGS) is one of the reverse genetics tools for analysis of gene function that uses viral vectors carrying a target gene fragment to produce dsRNA which trigger RNA‐mediated gene silencing. There are a number of viruses which have been modified to silence the gene of interest effectively with a sequence‐specific manner ...

Transcriptional Silencing of Geminiviral Promoter-Driven Transgenes Following Homologous Virus Infection

open access: yesMolecular Plant-Microbe Interactions, 2003
Promoters isolated from the Tomato leaf curl virus (TLCV) drive both constitutive and tissue-specific expression in transgenic tobacco. Following systemic TLCV infection of plants stably expressing TLCV promoter:GUS transgenes, transgene expression ...
