Large-genome eukaryotes use heritable cytosine methylation to silence promoters, especially those associated with transposons and imprinted genes. Cytosine methylation does not reinforce or replace ancestral gene regulation pathways but instead endows methylated genomes with the ability to repress specific promoters in a manner that is buffered against changes in the internal and external environment. Recent studies have shown that the targeting of de novo methylation depends on multiple inputs… 

Figures from this paper

Conservation and divergence in eukaryotic DNA methylation
TLDR
Next-generation sequencing used to investigate the DNA methylation patterns in eight divergent species, including green algae, flowering plants, insects, and vertebrates allowed a comprehensive comparison of whole-genome methylation profiles across the plant and animal kingdoms.
DNA Methylation: a Dynamic Regulator of Genome Organization and Gene Expression in Plants
TLDR
Recent studies suggest that methylation of CG dinucleotides provides a framework around which other epigenetic modifications are assembled on chromatin, leading to aberrant patterns of gene expression and abnormal development.
Mechanisms of Epigenetic Gene Activation in Disease: Dynamics of DNA Methylation and Demethylation
TLDR
The DNMT3A/B and DNMT1 families of DNA cytosine-5 methyltransferases (DNMT) are responsible for the establishment and maintenance of methylation patterns, respectively, which constitute relatively stable epigenetic marks that are transmitted through DNA replication and cellular division.
Maintenance and Inheritance of DNA Methylation in Arabidopsis
TLDR
This work analyzed Arabidopsis thaliana sperm and vegetative cells purified from pollen with mutations in the DRM to gain further insight into how DNA methylation is inherited and reprogrammed during sexual reproduction, and found that CMT2, a homolog of CMT3, is an active methyltransferase that maintains ~70% of total CHH methylation inArabidopsis, independently of RdDM.
Genome-Wide Evolutionary Analysis of Eukaryotic DNA Methylation
TLDR
The data suggest that land plants and vertebrates are under strong selective pressure to repress TEs, because of their sexual mode of reproduction, and indicate that gene body methylation is an ancient property of eukaryotic genomes.
DNA methylation dynamics in plant genomes.
Mammalian DNA methyltransferases.
TLDR
A great progress has been made in understanding of the enzymatic machinery involved in establishing and maintaining methylation patterns, which allowed for the development of new diagnostic tools and epigenetic treatment therapies and the new approaches hold a great potential.
Dnmt2 methyltransferases and immunity: An ancient overlooked connection between nucleotide modification and host defense?
TLDR
It is speculated that Dnmt2 proteins might be part of an ancient cytosine modification toolbox that is used to successfully respond to environmental challenges, including constantly evolving RNA and DNA substrates.
DNA methylation: TET proteins—guardians of CpG islands?
TLDR
It is proposed that the TET proteins have an important role in regulating DNA methylation fidelity, and that their inactivation contributes to the DNA hypermethylation phenotype often observed in cancer.
DNA Methylation and Demethylation in Arabidopsis
TLDR
An introduction to the mechanisms of DNA methylation and demethylation is provided and the biological relevance of these activities at different types of sequences is considered and possible regulatory roles ofDNA methylation in Arabidopsis are considered.

Cytosine methylation and mammalian development.
TLDR
It is reported here that the methylation status of the 5' regions of a panel of tissue-specific genes could not be correlated with expression in tissues of fetal and newborn mice, suggesting that the numerous published expression-methylation correlations may have described not a cause but a consequence of transcriptional activation.
A histone H3 methyltransferase controls DNA methylation in Neurospora crassa
TLDR
It is demonstrated that recombinant DIM-5 protein specifically methylates histone H3 and that replacement of lysine 9 in hist one H3 with either a leucine or an arginine phenocopies the dim-5 mutation, concluding that DNA methylation depends on histone methylation.
An Arabidopsis SET domain protein required for maintenance but not establishment of DNA methylation
TLDR
Results suggest that SUVH4 is involved in maintenance but not establishment of methylation at particular genomic regions, and that a heterochromatin protein 1 homolog, LHP1, had no effect on PAI methylation.
The Eukaryotic DNMT2 Genes Encode a New Class of Cytosine-5 DNA Methyltransferases*
TLDR
Evidence is presented here that the genomes of transgenic flies overexpressing the dDnmt2 protein also became hypermethylated at specific regions, providing solid evidence that the fly and mouse DNMT2 gene products are genuine cytosine-5 DNA methyltransferases.
Plant DNA methyltransferases
TLDR
Plants have at least three classes of cytosine methyltransferase which differ in protein structure and function; the chromomethylases, which are unique to plants, may preferentially methylate DNA in heterochromatin; the remaining class, with similarity to Dnmt3 methyltransferases of mammals, are putative de novo methyl transferases.
DNA (cytosine-5)-methyltransferases in mouse cells and tissues. Studies with a mechanism-based probe.
TLDR
Data suggest that any sequence-specific de novo methylation mediated by Dnmt1 is either under the control of regulatory factors that interact with DnMT1, or is cued by alternative secondary structures in DNA.
Transcriptional repression by the methyl-CpG-binding protein MeCP2 involves a histone deacetylase complex
TLDR
The data suggest that two global mechanisms of gene regulation, DNA methylation and histone deacetylation, can be linked by MeCP2, an abundant nuclear protein that is essential for mouse embryogenesis.
Control of CpNpG DNA methylation by the KRYPTONITE histone H3 methyltransferase
TLDR
The isolation of KRYPTONITE, a methyltransferase gene specific to H3 Lys 9, identified in a mutant screen for suppressors of gene silencing at the Arabidopsis thaliana SUPERMAN (SUP) locus is reported, which suggests that CpNpG DNA methylation is controlled by histone H 3 Lys 9 methylation, through interaction of CMT3 with methylated chromatin.
