    In vivo targeting of de novo DNA methylation by histone modifications in yeast and mouse

    Marco Morselli, William A Pastor ... Matteo Pellegrini
    DNA methylation deposition is dependent on the presence of H3K4me3 and H3K36me3 histone marks.

    Natural depletion of histone H1 in sex cells causes DNA demethylation, heterochromatin decondensation and transposon activation

    Shengbo He, Martin Vickers ... Xiaoqi Feng
    Transposon activation during male gametogenesis is caused by interactions between DNA demethylation and linker histone H1, developmental depletion of which promotes pollen fertility.

    Histone H1 prevents non-CG methylation-mediated small RNA biogenesis in Arabidopsis heterochromatin

    Jaemyung Choi, David B Lyons, Daniel Zilberman

    Structural basis for PRC2 decoding of active histone methylation marks H3K36me2/3

    Ksenia Finogenova, Jacques Bonnet ... Jürg Müller
    Nucleosome binding by PRC2 threads H3K27 into its active site via an interaction network set in register by unmodified H3K36.

    Methylation of histone H3K23 blocks DNA damage in pericentric heterochromatin during meiosis

    Romeo Papazyan, Ekaterina Voronina ... Sean D Taverna
    A previously unappreciated histone methylation pathway helps limit DNA double-strand break formation and recombination in heterochromatin during meiosis.

    A histone H3K9M mutation traps histone methyltransferase Clr4 to prevent heterochromatin spreading

    Chun-Min Shan, Jiyong Wang ... Songtao Jia
    A lysine-to-methionine mutation in histone H3 dominantly blocks histone H3K9 methylation by trapping its methyltransferase.

    Genome-wide detection of imprinted differentially methylated regions using nanopore sequencing

    Vahid Akbari, Jean-Michel Garant ... Steven JM Jones
    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.

    The histone modification reader ZCWPW1 links histone methylation to PRDM9-induced double-strand break repair

    Tao Huang, Shenli Yuan ... Hongbin Liu
    ZCWPW1 is a histone modification reader that localizes to DMC1-labelled double-strand break hotspots in a largely PRDM9-dependent manner, where it facilitates completion of synapsis by mediating DSB repair process.

    Determining the effects of paternal obesity on sperm chromatin at histone H3 lysine 4 tri-methylation in relation to the placental transcriptome and cellular composition

    Anne-Sophie Pepin, Patrycja A Jazwiec ... Sarah Kimmins
    Epigenomic and transcriptomic analysis reveals that paternal obesity influences sperm histone H3 lysine 4 tri-methylation enrichment and placenta gene expression, which in turn negatively impact its development and function in a manner that may contribute to metabolic disease in offspring.
