GH1-HMGA proteins restrict RNA-directed DNA methylation and antagonize linker histone H1 at euchromatic transposable elements

SPIN1 selectively silences evolutionarily young transposable elements through chromatin regulation

SPIN1 uses a histone-state-based mechanism to identify and repress young TEs in pluripotent cells, mechanistically distinct from its germline mode in which SPIN1 cooperates with the PIWI–piRNA pathway to promote DNA methylation, illustrating how a single histone reader engages distinct silencing machineries across cell...

Chromatin Homogenization Triggers Burst of CHH Methylation in Soybean.

Although chromatin states are closely associated with epigenetic modifications, how they influence each other remains to be fully elucidated. In this study, we found that mutation of DECREASED IN DNA METHYLATION 1 (DDM1) in soybean leads to genome-wide chromatin homogenization, characterized by a loosening of heterochr...

Chromatin-Assisted Targeting Enables Precise DNA Methylation Editing in Plants

SunTag-NOVA robustly installed DNA methylation and repressed transcription at the endogenous FWA, FT and TMM genes with minimal genome-wide off-target consequences, and establishes SunTag-NOVA as a specific epigenome-editing platform for plants.

J-domain proteins stimulate PKL-mediated chromatin compaction at H3K4-hypomethylated genomic loci

Chromatin accessibility varies widely across distinct genomic regions in eukaryotes, yet the mechanisms governing these differential patterns remain poorly understood. Here, we identify a subfamily of functionally redundant J-domain proteins (JDPs) that assemble into a protein complex with PICKLE (PKL), an evolutionari...

A plant DNMT3 induces non-CG methylation and affects gene expression in human cells

Summary CG methylation is the predominant form of DNA methylation across eukaryotes, whereas non-CG methylation in vertebrates is largely restricted to neurons and embryonic stem cells and is mediated by DNMT3 enzymes. In contrast, plant DNMT3 homologs catalyze extensive non-CG methylation across diverse tissues. To te...
