Post-transcriptional gene silencing (PTGS) in plants is an RNA-degradation mechanism that shows similarities to RNA interference (RNAi) in animals. RNA viruses as inducers, suppressors and targets of post-transcriptional gene silencing. Therefore, different types of methodologies have been advanced and modified for VIGS approach.  |  In plants, post-transcriptional gene silencing (PTGS) protects the genome from foreign genes and restricts the expression of certain endogenous genes for proper development. TGS occurs mainly when multiple repeats of a transgene are inserted in the genome of transgenic plants. Gene silencing is also currently being used in drug discovery efforts, such as synthetic lethality, high-throughput screening, and miniaturized RNAi screens. However, several breakthroughs in the field have been reported recently that blur this neat distinction. As a decision-making step of PTGS, aberrant transcripts from most endogenous coding genes are strictly sorted to the bidirectional … Initially, TGS was associated with the regulation of transposons through DNA methylation in the nucleus, whereas PTGS was shown to regulate virus infection through double-stranded RNA in the cytoplasm.

That is, a gene which would be expressed (“turned on”) under normal circumstances is switched off by machinery in the cell. Gene silencing is a technique that aims to reduce or eliminate the production of a protein from it’s corresponding gene. Gene silencing can occur either through repression of transcription, termed transcriptional gene silencing (TGS), or through mRNA degradation, termed post-transcriptional gene silencing (PTGS). In plants, RNA silencing not only serves as a component of the defense mechanism, but also participates in the regulation of endogenous gene expression in a variety of developmental processes. ABSTRACT: RNA interference, transcriptional gene silencing, virus induced gene silencing, and micro RNAs comprise a series of mechanisms capable of suppressing gene expression in plants. Sessile plants possess an assembly of signaling pathways that perceive and transmit environmental signals, ultimately resulting in transcriptional reprogramming. Initially, TGS was associated with the regulation of transposons through DNA methylation in the nucleus, whereas PTGS was shown to regulate virus infection through double-stranded RNA in the cytoplasm. Plants: Cosuppression or Epigenetic gene silencing: 1990: found that transgenes could suppress the expression of similar endogenous genes. Regulation of the Epigenome Various types of suppression Suppression of transposable elements stress response etc piRNA tasiRNA natsiRNA. DsRNAs that contain a sequence homologous to a promoter sequence can induce cytosine methylation on the promoter sequence in the nuclear DNA and subsequently induce TGS (for a review, see Matzke and Birchler 2005). HHS Walsh HA, Vanderschuren H, Taylor S, Rey MEC. Accordingly, RNA analysis of mutants impaired in silencing should uncover endogenous targets of this epigenetic regulation. NLM Re- cently, however, a subclass of Arabidopsis mutants revealed that the release of transcriptional gene silencing (TGS) does not neces-sarily require DNA demethylation. Mutations affecting transcriptional gene inactivation without altering nucleotide sequence methylation are described. Here, we review the recent progress about how the unwanted PTGS is avoided in plants. In plants, this phenomenon influences resistance to pathogenic viruses, suppression of transgene expression, and the inactivation of transposable elements. Post-Transcriptional Gene Silencing (PTGS) Also called RNA interference or RNAi ; Process results in down-regulation of a gene at the RNA level (i.e., after transcription) There is also gene silencing at the transcriptional level (TGS) Examples transposons, retroviral genes, heterochromatin; 2.
