Conservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha

This study investigates UV-B signaling in Marchantia polymorpha, showing that core components exist but regulatory interactions have diverged compared to Arabidopsis.

Antagonism between blue and red light-signalling controls thallus flatness in Marchantia polymorpha

This study shows blue and red light signaling antagonistically control thallus flatness in Marchantia polymorpha through phototropin and phytochrome pathways, with BBX transcription factors also acting antagonistically.

PHOTOTROPIN-mediated blue light signaling orients the asymmetry of Marchantia polymorpha spores

The paper shows blue light, via PHOTOTROPIN and NCH1, controls asymmetric cell division orientation in Marchantia polymorpha spores, establishing the first developmental axis.

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.
