The DNA methylation landscape of vertebrates is very particular compared to other organisms. In mammals, around 75% of CpG dinucleotides are methylated in See more

Significant progress has been made in understanding DNA methylation in the model plant Arabidopsis thaliana. DNA methylation in plants … See more

Diverse orders of insects show varied patterns of DNA methylation, from almost undetectable levels in flies to low levels in butterflies and higher in true bugs and some cockroaches … See more

DNA methylation is largely absent from Dictyostelium discoideum where it appears to occur at about 0.006% of cytosines. In contrast, DNA methylation is widely distributed in See more

During embryonic development
DNA methylation patterns are largely erased and then re-established between generations in mammals. Almost all of the methylations from … See more

In mammalian cells, DNA methylation occurs mainly at the C5 position of CpG dinucleotides and is carried out by two general classes of enzymatic activities – maintenance methylation and de novo methylation.
Maintenance … See more

Many fungi have low levels (0.1 to 0.5%) of cytosine methylation, whereas other fungi have as much as 5% of the genome methylated. This value seems to vary both among species and among isolates of the same species. There is also evidence that DNA methylation … See more
