text: Eukaryotic organisms have the remarkable ability to inherit states of gene
activity without altering the underlying DNA sequence. This epigenetic inheritance
can persist over thousands of years, providing an alternative to genetic mutations
as a substrate for natural selection. Epigenetic inheritance might be propagated
by differences in DNA methylation, post-translational histone modifications, and
deposition of histone variants. Mounting evidence also indicates that small interfering
RNA (siRNA)-mediated mechanisms play central roles in setting up and maintaining
states of gene activity. Much of the epigenetic machinery of many organisms, including
Arabidopsis, appears to be directed at silencing viruses and transposable elements,
with epigenetic regulation of endogenous genes being mostly derived from such
processes.

abstract:
- lang: eng
text: In a number of organisms, transgenes containing transcribed inverted repeats
(IRs) that produce hairpin RNA can trigger RNA-mediated silencing, which is associated
with 21-24 nucleotide small interfering RNAs (siRNAs). In plants, IR-driven RNA
silencing also causes extensive cytosine methylation of homologous DNA in both
the transgene "trigger" and any other homologous DNA sequences--"targets". Endogenous
genomic sequences, including transposable elements and repeated elements, are
also subject to RNA-mediated silencing. The RNA silencing gene ARGONAUTE4 (AGO4)
is required for maintenance of DNA methylation at several endogenous loci and
for the establishment of methylation at the FWA gene. Here, we show that mutation
of AGO4 substantially reduces the maintenance of DNA methylation triggered by
IR transgenes, but AGO4 loss-of-function does not block the initiation of DNA
methylation by IRs. AGO4 primarily affects non-CG methylation of the target sequences,
while the IR trigger sequences lose methylation in all sequence contexts. Finally,
we find that AGO4 and the DRM methyltransferase genes are required for maintenance
of siRNAs at a subset of endogenous sequences, but AGO4 is not required for the
accumulation of IR-induced siRNAs or a number of endogenous siRNAs, suggesting
that AGO4 may function downstream of siRNA production.

text: Recent progress in understanding the silencing of transposable elements in
the model plant Arabidopsis has revealed an interplay between DNA methylation,
histone methylation and small interfering RNAs. DNA and histone methylation are
not always sufficient to maintain silencing, and RNA-based reinforcement can be
needed to maintain as well as initiate it.

text: Multicellular eukaryotes produce small RNA molecules (approximately 21–24
nucleotides) of two general types, microRNA (miRNA) and short interfering RNA
(siRNA). They collectively function as sequence-specific guides to silence or
regulate genes, transposons, and viruses and to modify chromatin and genome structure.
Formation or activity of small RNAs requires factors belonging to gene families
that encode DICER (or DICER-LIKE [DCL]) and ARGONAUTE proteins and, in the case
of some siRNAs, RNA-dependent RNA polymerase (RDR) proteins. Unlike many animals,
plants encode multiple DCL and RDR proteins. Using a series of insertion mutants
of Arabidopsis thaliana, unique functions for three DCL proteins in miRNA (DCL1),
endogenous siRNA (DCL3), and viral siRNA (DCL2) biogenesis were identified. One
RDR protein (RDR2) was required for all endogenous siRNAs analyzed. The loss of
endogenous siRNA in dcl3 and rdr2 mutants was associated with loss of heterochromatic
marks and increased transcript accumulation at some loci. Defects in siRNA-generation
activity in response to turnip crinkle virus in dcl2 mutant plants correlated
with increased virus susceptibility. We conclude that proliferation and diversification
of DCL and RDR genes during evolution of plants contributed to specialization
of small RNA-directed pathways for development, chromatin structure, and defense.

text: Proteins of the ARGONAUTE family are important in diverse posttranscriptional
RNA-mediated gene-silencing systems as well as in transcriptional gene silencing
in Drosophila and fission yeast and in programmed DNA elimination in Tetrahymena.
We cloned ARGONAUTE4 (AGO4) from a screen for mutants that suppress silencing
of the Arabidopsis SUPERMAN(SUP) gene. The ago4-1 mutant reactivated silentSUP
alleles and decreased CpNpG and asymmetric DNA methylation as well as histone
H3 lysine-9 methylation. In addition,ago4-1 blocked histone and DNA methylation
and the accumulation of 25-nucleotide small interfering RNAs (siRNAs) that correspond
to the retroelement AtSN1. These results suggest that AGO4 and long siRNAs direct
chromatin modifications, including histone methylation and non-CpG DNA methylation.

text: RNA interference is a conserved process in which double-stranded RNA is processed
into 21–25 nucleotide siRNAs that trigger posttranscriptional gene silencing.
In addition, plants display a phenomenon termed RNA-directed DNA methylation (RdDM)
in which DNA with sequence identity to silenced RNA is de novo methylated at its
cytosine residues. This methylation is not only at canonical CpG sites but also
at cytosines in CpNpG and asymmetric sequence contexts. In this report, we study
the role of the DRM and CMT3 DNA methyltransferase genes in the initiation and
maintenance of RdDM. Neither drm nor cmt3 mutants affected the maintenance of
preestablished RNA-directed CpG methylation. However, drm mutants showed a nearly
complete loss of asymmetric methylation and a partial loss of CpNpG methylation.
The remaining asymmetric and CpNpG methylation was dependent on the activity of
CMT3, showing that DRM and CMT3 act redundantly to maintain non-CpG methylation.
These DNA methyltransferases appear to act downstream of siRNAs, since drm1 drm2
cmt3 triple mutants show a lack of non-CpG methylation but elevated levels of
siRNAs. Finally, we demonstrate that DRM activity is required for the initial
establishment of RdDM in all sequence contexts including CpG, CpNpG, and asymmetric
sites.

text: Epigenetic silenced alleles of the Arabidopsis SUPERMANlocus (the clark kent
alleles) are associated with dense hypermethylation at noncanonical cytosines
(CpXpG and asymmetric sites, where X = A, T, C, or G). A genetic screen for suppressors
of a hypermethylated clark kent mutant identified nine loss-of-function alleles
of CHROMOMETHYLASE3(CMT3), a novel cytosine methyltransferase homolog. These cmt3
mutants display a wild-type morphology but exhibit decreased CpXpG methylation
of the SUP gene and of other sequences throughout the genome. They also show reactivated
expression of endogenous retrotransposon sequences. These results show that a
non-CpG DNA methyltransferase is responsible for maintaining epigenetic gene silencing.
