Conservation of chromatin states and their association with transcription factors in land plants

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.

Population genomics of Marchantia polymorpha subspecies ruderalis reveals evidence of climate adaptation

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 ancestral chromatin landscape of land plants

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

Polycomb-mediated repression of paternal chromosomes maintains haploid dosage in diploid embryos of Marchantia

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

Deep evolutionary origin of gamete-directed zygote activation by KNOX/BELL transcription factors in green plants

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.
