BACKGROUND The association between DNA methylation and gene silencing has long been recognized; however, signals that initiate de novo methylation are largely unknown. In plants, recognition of RNAs that are inducers of posttranscriptional gene silencing (PTGS) can result in sequence-specific DNA methylation, and the aim of this work was to investigate whether heritable epigenetic changes can occur by this mechanism and if the Met1 methyltransferase is required. RESULTS RNA-directed DNA… Expand
Induction of RNA-directed DNA methylation and heritable transcriptional gene silencing as a tool to engineer novel traits in plants
TLDR
Epigenetic changes induced in a particular gene through RNA-directed DNA methylation and those induced randomly on the genome in terms of their use for plant biotechnology are reviewed. Expand
Virus-mediated efficient induction of epigenetic modifications of endogenous genes with phenotypic changes in plants.
TLDR
It is shown that heritable gene silencing can be induced by targeting dsRNA to the endogenous gene promoters in petunia and tomato plants, using the Cucumber mosaic virus (CMV)-based vector, and the observed inheritance of asymmetric DNA methylation is quite unique, suggesting that plants have a mechanism to maintain even asymmetric methylation. Expand
Size and positional effects of promoter RNA segments on virus-induced RNA-directed DNA methylation and transcriptional gene silencing
TLDR
Results indicate that both the length of dsRNA above the threshold and the frequency of cytosines at symmetric sites in the region targeted by ds RNA are the major factors that allow induction of heritable TGS via RdDM. Expand
Genetic analysis of RNA-mediated transcriptional gene silencing.
TLDR
Results obtained so far indicate that in response to RNA signals, different site-specific DNA methyltransferases (DMTases) cooperate with each other and eventually with histone-modifying enzymes to establish and maintain a transcriptionally inactive state at a homologous target promoter. Expand
DNA methylation maintenance consolidates RNA-directed DNA methylation and transcriptional gene silencing over generations in Arabidopsis thaliana.
TLDR
These findings suggest that establishment of DNA methylation at a particular region may be divided into distinct stages, and an initial phase of efficient, but still fully reversible, de novoDNA methylation and transcriptional genesilencing is followed by transition to efficient maintenance of cytosine methylation in a symmetric sequence context accompanied by persistence of gene silencing.

Virus-Mediated Targeted DNA Methylation Illuminates the Dynamics of Methylation in an Endogenous Plant Gene
TLDR
Methylation was rapidly induced but gradually decreased from the 3′ end of the target endogenous sequence in Nicotiana benthamiana, suggesting a mechanism to protect against the ectopic introduction of DNA methylation. Expand
RNA-directed DNA methylation in Arabidopsis
TLDR
A promoter double-stranded RNA-mediated transcriptional gene silencing system has been established in Arabidopsis and a genetic analysis of this system is helping to unravel the relationships among RNA signals, DNA methylation, and chromatin structure. Expand
Transcriptional silencing of Arabidopsis endogenes by single-stranded RNAs targeting the promoter region.
TLDR
It is demonstrated that a single-stranded antisense (AS) silencer targeting the promoter region can efficiently silence four Arabidopsis endogenes, with comparable efficiency to an IR silencer. Expand
RNA-mediated gene silencing
Abstract: A number of gene-silencing phenomena including co-suppression discovered in plants, quelling in fungi and RNA interference in animals have been revealed to have steps in common. All occurExpand
Transgene silencing may be mediated by aberrant sense promoter sequence transcripts generated from cryptic promoters
TLDR
It is indicated that methylation and silencing of transgenic promoters may be mediated by aberrant RNA transcribed from cryptic promoters at the transgene insertion site. Expand

RNA–DNA Interactions and DNA Methylation in Post-Transcriptional Gene Silencing
TLDR
An epigenetic model of PTGS in which transgene methylation is associated with an RNA–DNA interaction that ensures that PTGS is maintained is supported. Expand
DNA methylation and chromatin structure affect transcriptional and post-transcriptional transgene silencing in Arabidopsis
TLDR
Results show that DNA methylation and chromatin structure are common regulators of TGS and PTGS. Expand
Production of aberrant promoter transcripts contributes to methylation and silencing of unlinked homologous promoters in trans
TLDR
A chimeric ‘gene’ consisting of a nopaline synthase promoter (NOSpro) positioned downstream of the cauliflower mosaic virus 35S promoter and flanked at the 3′ end by a NOS terminator was constructed and introduced into the genome of a plant that normally expresses an unmethylated NOSpro‐neomycinphosphotransferase (nptII) gene.

Gene silencing mediated by promoter homology occurs at the level of transcription and results in meiotically heritable alterations in methylation and gene activity.
TLDR
Genomic sequencing demonstrated that the meiotic heritability of hpt silencing in the absence of the 271 locus was correlated with cytosine methylation primarily at CpG and CpNpG residues, which strengthens the distinction between silencing effects involving homology restricted to coding or promoter regions, respectively.

Position-Dependent Methylation and Transcriptional Silencing of Transgenes in Inverted T-DNA Repeats: Implications for Posttranscriptional Silencing of Homologous Host Genes in Plants
TLDR
Run-on transcription assays showed that promoter-driven transgenes located proximal to the center of a particular IR are transcriptionally more repressed than are the distal genes of the same IR locus, indicating that the palindromic arrangement of the Chstransgenes in the IR loci is critical for silencing.

TLDR
Short sequences were able to initiate PTGS of an endogenous gene, phyotene desaturase, although this occurred in the absence of DNA methylation, and this experimental approach provides important insights into the relationship between short RNA sequences and PTGS. Expand

It is shown here that transcriptional gene silencing accompanied by de novo methylation of a target promoter in plants can be triggered by a double‐stranded RNA containing promoter sequences. Expand

To investigate the origins of trans-silencing ability and susceptibility, the structures, flanking DNA sequences and chromosomal locations of a nopaline synthase promoter silencing locus, H2, and a sensitive target locu, K81, are analyzed. Expand
An RNA-Dependent RNA Polymerase Gene in Arabidopsis Is Required for Posttranscriptional Gene Silencing Mediated by a Transgene but Not by a Virus
TLDR
It is proposed that the role of SDE1 is to synthesize a double-stranded RNA initiator of posttranscriptional gene silencing, according to this idea, when a virus induces posttranscriptal genesilencing, the virus-encoded RNA polymerase would produce the double-Stranded RNA and Sde1 would be redundant.

TLDR
This work proposes a link between the DNA-based transgene methylation and the RNA-based gene silencing process and presents three examples in which silencing of nonviral transgenes prevented virus accumulation in potato virus X vector. Expand
