Time for another preprint from the lab: www.biorxiv.org/content/10.6... Led by @yuanyuanzhang.bsky.social and @defengshen.bsky.social. We found some surprising secrets that connect and uncouple root barrier formation with systemic nitrogen signaling in shoots. see the thread below for more details

A tunable receptor separates root barrier formation from nutrient signaling through ligand-perception states

In roots, the endodermis controls nutrient entry by forming a barrier known as the Casparian strip. Yet how barrier-associated processes interface with systemic signaling remains unclear. Here, we sho...

Multi-omics analyses of mutants for Marchantia polymorpha FERONIA and MARIS reveal a link between cell wall integrity and abscisic acid responses

Abstract. At the core of cell wall integrity (CWI) mechanisms that enable plant cells to coordinate their growth with their cell wall status, lies the tran

Wei Shi @wshisky.bsky.social & Merle‘s work is online. Wei really pushed this work from scratch and Merle linked it to MLA diversification…3rd (co-)first author paper in her PhD. Very proud PI! And only possible through collaboration with G. Döhlemann, @grandpahiro.bsky.social &, Matt Platre. (1/x)

Last one of the year: CRK2 controls the localisation of other RLKs to plasmodesmata. Great collaboration with @grandpahiro.bsky.social @rople.bsky.social and Ivan Kulich - thank you for the help and great collaboration!

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

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...
