New preprint! 😁 We uncover how early land plants evolved UV-B tolerance by dissecting the UVR8 pathway in Marchantia polymorpha. Conserved yet rewired—evolutionary plasticity revealed. 👉 www.biorxiv.org/content/10.1... #PlantScience #UVB #Evolution

Conservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha https://www.biorxiv.org/content/10.1101/2025.07.16.665153v1

Happy to share this work we did together with @yuankeliang.bsky.social in @romanulm.bsky.social lab. We looked in detail at UVR8-mediated UV-B signaling in Marchantia and found some conserved functions but also a few surprises! #plantscience #marchantia #UVR8

New from the Gehring lab

POSTDOC POSITION AVAILABLE, Geneva, Switzerland - Applications are invited for a postdoc position to study UV-B perception and signalling in plants. Please apply, forward to suitable candidates, and/or repost; many thanks! Deadline February 24, 2025. See www.ulm-lab.ch for more information.

Do you want an EMS-like drug that you can easily use in your lab or your garden shed to generate structural variation in your favorite plant? We show here that the topo2 inhibitor & common chemotherapy drug etoposide works really well to generate structural variation .
