Functional diversification of ERF transcription factors in land plants

This study investigates the functional diversification of ERF transcription factors across land plants using liverwort and Arabidopsis, revealing conserved and lineage-specific roles in development and stress responses.

A paralog of a clonal propagation regulator promotes cell-cycle re-entry during thallus regeneration in Marchantia polymorpha

This study identifies MpGC1L, a paralog of MpGCAM1, as a positive regulator of regeneration in Marchantia polymorpha, showing distinct roles in cell-cycle re-entry during thallus regeneration.

A SABATH family enzyme regulates development via the gibberellin-related pathway in the liverwort Marchantia polymorpha

This study identifies MpSABATH2 in liverwort Marchantia polymorpha as essential for development, linking it to gibberellin metabolism and showing convergent evolution of SABATH functions in land plants.

MarpolBase: Genome database for Marchantia polymorpha featuring high quality reference genome sequences

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

The beginnings of light-dependent nuclear relocation in land plants

This study shows that light-dependent nuclear relocation in land plants evolved in the common ancestor of land plants and diverged during evolution, with similar but less stable responses observed in liverworts compared to Arabidopsis.

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.

Chromatin organization in early land plants reveals an ancestral association between H3K27me3, transposons, and constitutive heterochromatin

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