text: 'Genetic variation is generally regarded as a prerequisite for evolution.
In principle, epigenetic information inherited independently of DNA sequence can
also enable evolution, but whether this occurs in natural populations is unknown.
Here we show that single-nucleotide and epigenetic gene body DNA methylation (gbM)
polymorphisms explain comparable amounts of expression variance in Arabidopsis
thaliana populations. We genetically demonstrate that gbM regulates
transcription, and we identify and genetically validate many associations between
gbM polymorphism and the variation of complex traits: fitness under heat and drought,
flowering time and accumulation of diverse minerals. Epigenome-wide association
studies pinpoint trait-relevant genes with greater precision than genetic association
analyses, probably due to reduced linkage disequilibrium between gbM variants.
Finally, we identify numerous associations between gbM epialleles and diverse
environmental conditions in native habitats, suggesting that gbM facilitates adaptation.
Overall, our results indicate that epigenetic methylation variation fundamentally
shapes phenotypic diversity in a natural population.'

text: The males and females of the brine shrimp Artemia franciscana are highly dimorphic,
and this dimorphism is associated with substantial sex-biased gene expression
in heads and gonads. How these sex-specific patterns of expression are regulated
at the molecular level is unknown. A. franciscana also has differentiated ZW sex
chromosomes, with complete dosage compensation, but the molecular mechanism through
which compensation is achieved is unknown. Here, we conducted CUT&TAG assays targeting
7 post-translational histone modifications (H3K27me3, H3K9me2, H3K9me3, H3K36me3,
H3K27ac, H3K4me3, and H4K16ac) in heads and gonads of A. franciscana, allowing
us to divide the genome into 12 chromatin states. We further defined functional
chromatin signatures for all genes, which were correlated with transcript level
abundances. Differences in the occupancy of the profiled epigenetic marks between
sexes were associated with differential gene expression between males and females.
Finally, we found a significant enrichment of the permissive H4K16ac histone mark
in the Z-specific region in both tissues of females but not males, supporting
the role of this histone mark in mediating dosage compensation of the Z chromosome.

text: Many modes and mechanisms of epigenetic inheritance have been elucidated in
eukaryotes. Most of them are relatively short-term, generally not exceeding one
or a few organismal generations. However, emerging evidence indicates that one
mechanism, cytosine DNA methylation, can mediate epigenetic inheritance over much
longer timescales, which are mostly or completely inaccessible in the laboratory.
Here we discuss the evidence for, and mechanisms and implications of, such long-term
epigenetic inheritance. We argue that compelling evidence supports the long-term
epigenetic inheritance of gene body methylation, at least in the model angiosperm
Arabidopsis thaliana, and that variation in such methylation can therefore serve
as an epigenetic basis for phenotypic variation in natural populations.

text: Methylation of CG dinucleotides (mCGs), which regulates eukaryotic genome
functions, is epigenetically propagated by Dnmt1/MET1 methyltransferases. How
mCG is established and transmitted across generations despite imperfect enzyme
fidelity is unclear. Whether mCG variation in natural populations is governed
by genetic or epigenetic inheritance also remains mysterious. Here, we show that
MET1 de novo activity, which is enhanced by existing proximate methylation, seeds
and stabilizes mCG in Arabidopsis thaliana genes. MET1 activity is restricted
by active demethylation and suppressed by histone variant H2A.Z, producing localized
mCG patterns. Based on these observations, we develop a stochastic mathematical
model that precisely recapitulates mCG inheritance dynamics and predicts intragenic
mCG patterns and their population-scale variation given only CG site spacing.
Our results demonstrate that intragenic mCG establishment, inheritance, and variance
constitute a unified epigenetic process, revealing that intragenic mCG undergoes
large, millennia-long epigenetic fluctuations and can therefore mediate evolution
on this timescale.

text: Cytosine methylation within CG dinucleotides (mCG) can be epigenetically inherited
over many generations. Such inheritance is thought to be mediated by a semiconservative
mechanism that produces binary present/absent methylation patterns. However, we
show here that in Arabidopsis thaliana h1ddm1 mutants, intermediate heterochromatic
mCG is stably inherited across many generations and is quantitatively associated
with transposon expression. We develop a mathematical model that estimates the
rates of semiconservative maintenance failure and de novo methylation at each
transposon, demonstrating that mCG can be stably inherited at any level via a
dynamic balance of these activities. We find that DRM2 – the core methyltransferase
of the RNA-directed DNA methylation pathway – catalyzes most of the heterochromatic
de novo mCG, with de novo rates orders of magnitude higher than previously thought,
whereas chromomethylases make smaller contributions. Our results demonstrate that
stable epigenetic inheritance of mCG in plant heterochromatin is enabled by extensive
de novo methylation.

text: Flowering plants utilize small RNA molecules to guide DNA methyltransferases
to genomic sequences. This RNA-directed DNA methylation (RdDM) pathway preferentially
targets euchromatic transposable elements. However, RdDM is thought to be recruited
by methylation of histone H3 at lysine 9 (H3K9me), a hallmark of heterochromatin.
How RdDM is targeted to euchromatin despite an affinity for H3K9me is unclear.
Here we show that loss of histone H1 enhances heterochromatic RdDM, preferentially
at nucleosome linker DNA. Surprisingly, this does not require SHH1, the RdDM component
that binds H3K9me. Furthermore, H3K9me is dispensable for RdDM, as is CG DNA methylation.
Instead, we find that non-CG methylation is specifically associated with small
RNA biogenesis, and without H1 small RNA production quantitatively expands to
non-CG methylated loci. Our results demonstrate that H1 enforces the separation
of euchromatic and heterochromatic DNA methylation pathways by excluding the small
RNA-generating branch of RdDM from non-CG methylated heterochromatin.

text: 'Parent-of-origin–dependent gene expression in mammals and flowering plants
results from differing chromatin imprints (genomic imprinting) between maternally
and paternally inherited alleles. Imprinted gene expression in the endosperm of
seeds is associated with localized hypomethylation of maternally but not paternally
inherited DNA, with certain small RNAs also displaying parent-of-origin–specific
expression. To understand the evolution of imprinting mechanisms in Oryza sativa
(rice), we analyzed imprinting divergence among four cultivars that span both
japonica and indica subspecies: Nipponbare, Kitaake, 93-11, and IR64. Most imprinted
genes are imprinted across cultivars and enriched for functions in chromatin and
transcriptional regulation, development, and signaling. However, 4 to 11% of imprinted
genes display divergent imprinting. Analyses of DNA methylation and small RNAs
revealed that endosperm-specific 24-nt small RNA–producing loci show weak RNA-directed
DNA methylation, frequently overlap genes, and are imprinted four times more often
than genes. However, imprinting divergence most often correlated with local DNA
methylation epimutations (9 of 17 assessable loci), which were largely stable
within subspecies. Small insertion/deletion events and transposable element insertions
accompanied 4 of the 9 locally epimutated loci and associated with imprinting
divergence at another 4 of the remaining 8 loci. Correlating epigenetic and genetic
variation occurred at key regulatory regions—the promoter and transcription start
site of maternally biased genes, and the promoter and gene body of paternally
biased genes. Our results reinforce models for the role of maternal-specific DNA
hypomethylation in imprinting of both maternally and paternally biased genes,
and highlight the role of transposition and epimutation in rice imprinting evolution.'

text: DNA methylation and histone H1 mediate transcriptional silencing of genes
and transposable elements, but how they interact is unclear. In plants and animals
with mosaic genomic methylation, functionally mysterious methylation is also common
within constitutively active housekeeping genes. Here, we show that H1 is enriched
in methylated sequences, including genes, of Arabidopsis thaliana, yet this enrichment
is independent of DNA methylation. Loss of H1 disperses heterochromatin, globally
alters nucleosome organization, and activates H1-bound genes, but only weakly
de-represses transposable elements. However, H1 loss strongly activates transposable
elements hypomethylated through mutation of DNA methyltransferase MET1. Hypomethylation
of genes also activates antisense transcription, which is modestly enhanced by
H1 loss. Our results demonstrate that H1 and DNA methylation jointly maintain
transcriptional homeostasis by silencing transposable elements and aberrant intragenic
transcripts. Such functionality plausibly explains why DNA methylation, a well-known
mutagen, has been maintained within coding sequences of crucial plant and animal
genes.

text: Epigenetic reprogramming is required for proper regulation of gene expression
in eukaryotic organisms. In Arabidopsis, active DNA demethylation is crucial for
seed viability, pollen function, and successful reproduction. The DEMETER (DME)
DNA glycosylase initiates localized DNA demethylation in vegetative and central
cells, so-called companion cells that are adjacent to sperm and egg gametes, respectively.
In rice, the central cell genome displays local DNA hypomethylation, suggesting
that active DNA demethylation also occurs in rice; however, the enzyme responsible
for this process is unknown. One candidate is the rice REPRESSOR OF SILENCING
1a (ROS1a) gene, which is related to DME and is essential for rice seed viability
and pollen function. Here, we report genome-wide analyses of DNA methylation in
wild-type and ros1a mutant sperm and vegetative cells. We find that the rice vegetative
cell genome is locally hypomethylated compared with sperm by a process that requires
ROS1a activity. We show that many ROS1a target sequences in the vegetative cell
are hypomethylated in the rice central cell, suggesting that ROS1a also demethylates
the central cell genome. Similar to Arabidopsis, we show that sperm non-CG methylation
is indirectly promoted by DNA demethylation in the vegetative cell. These results
reveal that DNA glycosylase-mediated DNA demethylation processes are conserved
in Arabidopsis and rice, plant species that diverged 150 million years ago. Finally,
although global non-CG methylation levels of sperm and egg differ, the maternal
and paternal embryo genomes show similar non-CG methylation levels, suggesting
that rice gamete genomes undergo dynamic DNA methylation reprogramming after cell
fusion.

text: "Background\r\nDNA methylation of active genes, also known as gene body methylation,
is found in many animal and plant genomes. Despite this, the transcriptional and
developmental role of such methylation remains poorly understood. Here, we explore
the dynamic range of DNA methylation in honey bee, a model organism for gene body
methylation.\r\n\r\nResults\r\nOur data show that CG methylation in gene bodies
globally fluctuates during honey bee development. However, these changes cause
no gene expression alterations. Intriguingly, despite the global alterations,
tissue-specific CG methylation patterns of complete genes or exons are rare, implying
robust maintenance of genic methylation during development. Additionally, we show
that CG methylation maintenance fluctuates in somatic cells, while reaching maximum
fidelity in sperm cells. Finally, unlike universally present CG methylation, we
discovered non-CG methylation specifically in bee heads that resembles such methylation
in mammalian brain tissue.\r\n\r\nConclusions\r\nBased on these results, we propose
that gene body CG methylation can oscillate during development if it is kept to
a level adequate to preserve function. Additionally, our data suggest that heightened
non-CG methylation is a conserved regulator of animal nervous systems."

text: The DEMETER (DME) DNA glycosylase catalyzes genome-wide DNA demethylation
and is required for endosperm genomic imprinting and embryo viability. Targets
of DME-mediated DNA demethylation reside in small, euchromatic, AT-rich transposons
and at the boundaries of large transposons, but how DME interacts with these diverse
chromatin states is unknown. The STRUCTURE SPECIFIC RECOGNITION PROTEIN 1 (SSRP1)
subunit of the chromatin remodeler FACT (facilitates chromatin transactions),
was previously shown to be involved in the DME-dependent regulation of genomic
imprinting in Arabidopsis endosperm. Therefore, to investigate the interaction
between DME and chromatin, we focused on the activity of the two FACT subunits,
SSRP1 and SUPPRESSOR of TY16 (SPT16), during reproduction in Arabidopsis. We found
that FACT colocalizes with nuclear DME in vivo, and that DME has two classes of
target sites, the first being euchromatic and accessible to DME, but the second,
representing over half of DME targets, requiring the action of FACT for DME-mediated
DNA demethylation genome-wide. Our results show that the FACT-dependent DME targets
are GC-rich heterochromatin domains with high nucleosome occupancy enriched with
H3K9me2 and H3K27me1. Further, we demonstrate that heterochromatin-associated
linker histone H1 specifically mediates the requirement for FACT at a subset of
DME-target loci. Overall, our results demonstrate that FACT is required for DME
targeting by facilitating its access to heterochromatin.

text: Cytosine methylation regulates essential genome functions across eukaryotes,
but the fundamental question of whether nucleosomal or naked DNA is the preferred
substrate of plant and animal methyltransferases remains unresolved. Here, we
show that genetic inactivation of a single DDM1/Lsh family nucleosome remodeler
biases methylation toward inter-nucleosomal linker DNA in Arabidopsis thaliana
and mouse. We find that DDM1 enables methylation of DNA bound to the nucleosome,
suggesting that nucleosome-free DNA is the preferred substrate of eukaryotic methyltransferases
in vivo. Furthermore, we show that simultaneous mutation of DDM1 and linker histone
H1 in Arabidopsis reproduces the strong linker-specific methylation patterns of
species that diverged from flowering plants and animals over a billion years ago.
Our results indicate that in the absence of remodeling, nucleosomes are strong
barriers to DNA methyltransferases. Linker-specific methylation can evolve simply
by breaking the connection between nucleosome remodeling and DNA methylation.

text: The discovery of introns four decades ago was one of the most unexpected findings
in molecular biology. Introns are sequences interrupting genes that must be removed
as part of messenger RNA production. Genome sequencing projects have shown that
most eukaryotic genes contain at least one intron, and frequently many. Comparison
of these genomes reveals a history of long evolutionary periods during which few
introns were gained, punctuated by episodes of rapid, extensive gain. However,
although several detailed mechanisms for such episodic intron generation have
been proposed, none has been empirically supported on a genomic scale. Here we
show how short, non-autonomous DNA transposons independently generated hundreds
to thousands of introns in the prasinophyte Micromonas pusilla and the pelagophyte
Aureococcus anophagefferens. Each transposon carries one splice site. The other
splice site is co-opted from the gene sequence that is duplicated upon transposon
insertion, allowing perfect splicing out of the RNA. The distributions of sequences
that can be co-opted are biased with respect to codons, and phasing of transposon-generated
introns is similarly biased. These transposons insert between pre-existing nucleosomes,
so that multiple nearby insertions generate nucleosome-sized intervening segments.
Thus, transposon insertion and sequence co-option may explain the intron phase
biases and prevalence of nucleosome-sized exons observed in eukaryotes. Overall,
the two independent examples of proliferating elements illustrate a general DNA
transposon mechanism that can plausibly account for episodes of rapid, extensive
intron gain during eukaryotic evolution.

text: Cytosine DNA methylation regulates the expression of eukaryotic genes and
transposons. Methylation is copied by methyltransferases after DNA replication,
which results in faithful transmission of methylation patterns during cell division
and, at least in flowering plants, across generations. Transgenerational inheritance
is mediated by a small group of cells that includes gametes and their progenitors.
However, methylation is usually analyzed in somatic tissues that do not contribute
to the next generation, and the mechanisms of transgenerational inheritance are
inferred from such studies. To gain a better understanding of how DNA methylation
is inherited, we analyzed purified Arabidopsis thaliana sperm and vegetative cells-the
cell types that comprise pollen-with mutations in the DRM, CMT2, and CMT3 methyltransferases.
We find that DNA methylation dependency on these enzymes is similar in sperm,
vegetative cells, and somatic tissues, although DRM activity extends into heterochromatin
in vegetative cells, likely reflecting transcription of heterochromatic transposons
in this cell type. We also show that lack of histone H1, which elevates heterochromatic
DNA methylation in somatic tissues, does not have this effect in pollen. Instead,
levels of CG methylation in wild-type sperm and vegetative cells, as well as in
wild-type microspores from which both pollen cell types originate, are substantially
higher than in wild-type somatic tissues and similar to those of H1-depleted roots.
Our results demonstrate that the mechanisms of methylation maintenance are similar
between pollen and somatic cells, but the efficiency of CG methylation is higher
in pollen, allowing methylation patterns to be accurately inherited across generations.

text: Cytosine methylation is a DNA modification with important regulatory functions
in eukaryotes. In flowering plants, sexual reproduction is accompanied by extensive
DNA demethylation, which is required for proper gene expression in the endosperm,
a nutritive extraembryonic seed tissue. Endosperm arises from a fusion of a sperm
cell carried in the pollen and a female central cell. Endosperm DNA demethylation
is observed specifically on the chromosomes inherited from the central cell in
Arabidopsis thaliana, rice, and maize, and requires the DEMETER DNA demethylase
in Arabidopsis. DEMETER is expressed in the central cell before fertilization,
suggesting that endosperm demethylation patterns are inherited from the central
cell. Down-regulation of the MET1 DNA methyltransferase has also been proposed
to contribute to central cell demethylation. However, with the exception of three
maize genes, central cell DNA methylation has not been directly measured, leaving
the origin and mechanism of endosperm demethylation uncertain. Here, we report
genome-wide analysis of DNA methylation in the central cells of Arabidopsis and
rice—species that diverged 150 million years ago—as well as in rice egg cells.
We find that DNA demethylation in both species is initiated in central cells,
which requires DEMETER in Arabidopsis. However, we do not observe a global reduction
of CG methylation that would be indicative of lowered MET1 activity; on the contrary,
CG methylation efficiency is elevated in female gametes compared with nonsexual
tissues. Our results demonstrate that locus-specific, active DNA demethylation
in the central cell is the origin of maternal chromosome hypomethylation in the
endosperm.

text: Genomic imprinting, an inherently epigenetic phenomenon defined by parent
of origin-dependent gene expression, is observed in mammals and flowering plants.
Genome-scale surveys of imprinted expression and the underlying differential epigenetic
marks have led to the discovery of hundreds of imprinted plant genes and confirmed
DNA and histone methylation as key regulators of plant imprinting. However, the
biological roles of the vast majority of imprinted plant genes are unknown, and
the evolutionary forces shaping plant imprinting remain rather opaque. Here, we
review the mechanisms of plant genomic imprinting and discuss theories of imprinting
evolution and biological significance in light of recent findings.

text: Dnmt1 epigenetically propagates symmetrical CG methylation in many eukaryotes.
Their genomes are typically depleted of CG dinucleotides because of imperfect
repair of deaminated methylcytosines. Here, we extensively survey diverse species
lacking Dnmt1 and show that, surprisingly, symmetrical CG methylation is nonetheless
frequently present and catalyzed by a different DNA methyltransferase family,
Dnmt5. Numerous Dnmt5-containing organisms that diverged more than a billion years
ago exhibit clustered methylation, specifically in nucleosome linkers. Clustered
methylation occurs at unprecedented densities and directly disfavors nucleosomes,
contributing to nucleosome positioning between clusters. Dense methylation is
enabled by a regime of genomic sequence evolution that enriches CG dinucleotides
and drives the highest CG frequencies known. Species with linker methylation have
small, transcriptionally active nuclei that approach the physical limits of chromatin
compaction. These features constitute a previously unappreciated genome architecture,
in which dense methylation influences nucleosome positions, likely facilitating
nuclear processes under extreme spatial constraints.

text: Centromeres mediate chromosome segregation and are defined by the centromere-specific
histone H3 variant (CenH3)/centromere protein A (CENP-A). Removal of CenH3 from
centromeres is a general property of terminally differentiated cells, and the
persistence of CenH3 increases the risk of diseases such as cancer. However, active
mechanisms of centromere disassembly are unknown. Nondividing Arabidopsis pollen
vegetative cells, which transport engulfed sperm by extended tip growth, undergo
loss of CenH3; centromeric heterochromatin decondensation; and bulk activation
of silent rRNA genes, accompanied by their translocation into the nucleolus. Here,
we show that these processes are blocked by mutations in the evolutionarily conserved
AAA-ATPase molecular chaperone, CDC48A, homologous to yeast Cdc48 and human p97
proteins, both of which are implicated in ubiquitin/small ubiquitin-like modifier
(SUMO)-targeted protein degradation. We demonstrate that CDC48A physically associates
with its heterodimeric cofactor UFD1-NPL4, known to bind ubiquitin and SUMO, as
well as with SUMO1-modified CenH3 and mutations in NPL4 phenocopy cdc48a mutations.
In WT vegetative cell nuclei, genetically unlinked ribosomal DNA (rDNA) loci are
uniquely clustered together within the nucleolus and all major rRNA gene variants,
including those rDNA variants silenced in leaves, are transcribed. In cdc48a mutant
vegetative cell nuclei, however, these rDNA loci frequently colocalized with condensed
centromeric heterochromatin at the external periphery of the nucleolus. Our results
indicate that the CDC48ANPL4 complex actively removes sumoylated CenH3 from centromeres
and disrupts centromeric heterochromatin to release bulk rRNA genes into the nucleolus
for ribosome production, which fuels single nucleus-driven pollen tube growth
and is essential for plant reproduction.

text: Transposons are selfish genetic sequences that can increase their copy number
and inflict substantial damage on their hosts. To combat these genomic parasites,
plants have evolved multiple pathways to identify and silence transposons by methylating
their DNA. Plants have also evolved mechanisms to limit the collateral damage
from the antitransposon machinery. In this review, we examine recent developments
that have elucidated many of the molecular workings of these pathways. We also
highlight the evidence that the methylation and demethylation pathways interact,
indicating that plants have a highly sophisticated, integrated system of transposon
defense that has an important role in the regulation of gene expression.
