The paper profiles histone post-translational modifications across eukaryotic lineages to assess conservation of chromatin states, finding conserved euchromatin states but diverse repressive heterochromatin configurations.

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