The paper shows that the endosperm supplies cell-wall-loosening proteins to the maternal seed coat, enabling maternal cell elongation and seed growth through a regulated secretory program.

The paper maps single-residue effects of H2A and H2A.Z nucleosome-core variations on cellular functions, revealing non-chromatin regulatory roles and stress-related benefits.

The paper shows GH1-HMGA proteins restrict RdDM at euchromatic TEs by limiting siRNA and competing with H1 for chromatin binding.

This study identifies histone-based chromatin regulation components in Asgard archaea, suggesting these features predate eukaryogenesis.

The paper shows that H2A variants guide heterochromatin formation in Arabidopsis, with H2A.W promoting and H2A.Z inhibiting it, while pericentromeric regions form heterochromatin autonomously.

This study shows that nucleosome positioning suppresses cryptic antisense transcription in fission yeast, with CHD1-family remodelers and the PAF complex playing a key role.

MarpolBase provides high-quality reference genomes for Marchantia polymorpha and offers tools for genome analysis and gene nomenclature.

This study identifies CDCA7 as a trans-regulator of CG methylation in Arabidopsis thaliana, showing its role in local adaptation through allele variation.

The paper shows that different ATG8 isoforms in Arabidopsis have specialized functions in autophagy, as demonstrated by a mutant lacking all nine isoforms and complementation experiments.

This study shows that single residue changes in histone H2A.Z can lead to new functions and fitness trade-offs by altering gene expression.

This study identifies conserved chromatin states in Arabidopsis thaliana and Marchantia polymorpha, showing their association with transcription factor binding and function across land plant evolution.

This study analyzes genetic variation in Marchantia polymorpha subspecies ruderalis to identify climate adaptation signals, finding significant differentiation between European and Japanese populations linked to temperature and precipitation.

The paper maps the chromatin landscape of hornworts to infer the ancestral chromatin structure of bryophytes and land plants.

The paper investigates how histone variants, particularly H2A variants, influence chromatin states in Arabidopsis thaliana by examining their interactions with chromatin remodelers like DDM1.

This study reveals how DDM1 remodels H2A.W nucleosomes in Arabidopsis, enabling chromatin writers to access heterochromatin for DNA methylation.

The paper investigates epigenetic reprogramming of imprinting during meiosis in the bryophyte Marchantia polymorpha, showing that imprinting is erased during meiosis and re-established in meiotic spores.

The paper shows that paternal chromosome repression via Polycomb mark H3K27me3 maintains haploid gene dosage in diploid embryos of Marchantia polymorpha.

The paper identifies chromatin landscapes in Arabidopsis that regulate transcriptional activity, showing that histone variants and modifications define these landscapes rather than the reverse.

The paper shows that H2A.W and H3K9me work together with H1 and CH methylation to silence transposons in Arabidopsis.

Ultra-long-read sequencing resolves Arabidopsis centromeres, revealing their genetic and epigenetic structure and dynamics.

The paper shows that KNOX/BELL transcription factors in Marchantia polymorpha initiate zygotic development similarly to Chlamydomonas reinhardtii, suggesting zygote activation is the ancestral role of these factors.

The paper investigates how PTMs on H2A variants in Arabidopsis affect cell functions and DNA damage response through motif-specific cross-talk.

This study shows that H2A.W and H1 co-regulate heterochromatin accessibility and DNA methylation in flowering plants by modulating H1 deposition and non-CG methylation.

The paper analyzes chromatin organization in the early land plant Marchantia polymorpha, revealing an ancestral role of H3K27me3 in transposon silencing and heterochromatin formation.
