Nucleosomes and linker histones block eukaryotic cytosine methylation.

The METHYL-CpG-BINDING DOMAIN 7 (MBD7) complex promotes the activation (rather than repression) of transgenes that undergo DNA methylation and it does so without significantly altering their methylation status, placing this complex downstream of DNA methylation.

Genome-wide identification of long non-coding RNAs produced by RNA Polymerase V identifies their role in heterochromatin maintenance on the boundaries of repressed regions.

Population genomics in Arabidopsis thaliana uncovers an extensive repertoire of active transposable element families at the species level and reveals their importance as a source of rare alleles with large effects.

Transient adaptation to environmental fluctuations in plants is mediated through discrete epigenetic changes.

A viral protein hijacks the key effector of transcriptional gene silencing, Su(var)3-9, to evade host plant surveillance.

Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.

Individual scientists, scientific communities and scientific journals can do more to assess the publication of irreproducible results, to promote good science, and to increase the efficiency with which the scientific community self-corrects.
