A previously unappreciated histone methylation pathway helps limit DNA double-strand break formation and recombination in heterochromatin during meiosis.
In humans, specific sequence features can predict whether meiotic recombination occurs at sites bound by the protein PRDM9, whose DNA-binding zinc-finger domain can unexpectedly bind to gene promoters and to other copies of PRDM9.

A genome-wide map of human allele-specific methylation using long-read sequencing detects novel imprinted DNA methylation events and reveals large blocks of subtle parent-of-origin bias in DNA methylation with mutual exclusive allelic H3K36me3 and H3K27me3 histone modifications.

Genome-wide chromatin mapping during bacterial-fungal cocultivation identifies the Myb-like transcription factor BasR as the major regulatory node of bacteria-triggered production of fungal secondary metabolites.

The BPTF PHD finger is inhibited from binding the methylated H3 tails in the context of the nucleosome due to their robust interaction with the nucleosomal DNA, which can be modulated by additional histone PTMs.

Proximity biotinylation of the Drosophila centromere suggests a role of RNA helicases, centromeric transcripts, and centromeric R-loops for centromere function.
Analyses of cell type-specific data show that the maternal alleles of genes related to establishing and breaking seed dormancy are suppressed by different combinations of epigenetic marks in the endosperm of Arabidopsis.
A previously uncharacterized type of bivalent chromatin plays an important role controlling the timely induction of genes involved in making a potent defense metabolite upon a pathogen signal in Arabidopsis.

Loss of Dnmt3a in excitatory neurons disrupts synaptic morphology and behavior, and triggers the expansion of H3K27me3 binding, suggestive of increased polycomb repression.
