Conservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha Ultraviolet-B radiation (UV-B) poses a major challenge to all forms of plant life. The liverwort Marchantia polymorpha (Marchantia) serves as a key model organism to study signaling pathways and to in...

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

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

A transcriptional atlas of early Arabidopsis seed development suggests mechanisms for inter-tissue coordination Successful seed development is essential for flowering plant reproduction and requires the coordination of three genetically distinct tissues: the embryo and endosperm, which are the products of ferti...

A simple method to efficiently generate structural variation in plants Phenotypic variation is essential for the selection of new traits of interest. Structural variants, consisting of deletions, duplications, inversions, and translocations, have greater potential for ph...

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 .
