In 1925, 5-methylcytosine was first reported in bacteria. However, its biological importance
was not intuitive for several decades. After this initial lag, the ubiquitous presence of this …

Cytosine DNA methylation is a stable epigenetic mark that is crucial for diverse biological
processes, including gene and transposon silencing, imprinting and X chromosome …

DNA methylation is an epigenetic modification of the genome involved in the regulation of
gene expression and modulation of chromatin structure. Plant genomes are widely …

DNA methylation is an important epigenetic mark involved in diverse biological processes.
In plants, DNA methylation can be established through the RNA-directed DNA methylation …

Transposable elements (TEs) are genomic parasites that selfishly replicate at the expense of
host fitness. Fifty years of evolutionary studies of TEs have concentrated on the deleterious …

Plants have evolved an elaborate transcriptional machinery dedicated to eliciting sequence-
specific, chromatin-based gene silencing. Two Pol II-related, plant-specific RNA …

Transposable elements make up a substantial proportion of most plant genomes. Because
they are potentially highly mutagenic, transposons are controlled by a set of mechanisms …

Patterns of DNA cytosine methylation are subject to mitotic inheritance in both plants and
vertebrates. Plants use 5-methylcytosine glycosylases and the base excision repair pathway …

Transposable elements (TEs) are mobile units of DNA that comprise large portions of plant
genomes. Besides creating mutations via transposition and contributing to genome size, TEs …

Genomes must balance active suppression of transposable elements (TEs) with the need to
maintain gene expression. In Arabidopsis, euchromatic TEs are targeted by RNA-directed …
