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

Yuanke Liang, Roman Podolec, Richard Chappuis, Emmanuel Défossez, Gaétan Glauser, Johannes Rötzer, Sara Christina Stolze, Liam Dolan, Hirofumi Nakagami, Emilie Demarsy, Roman Ulm

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

Photoreceptor-induced LHL4 protects photosystem II in Chlamydomonas reinhardtii

Marie Dannay, Chloé Bertin, Eva Cavallari, Pascal Albanese, Dimitri Tolleter, Cécile Giustini, Mathilde Menneteau, Sabine Brugière, Yohann Couté, Giovanni Finazzi, Emilie Demarsy, Roman Ulm, Guillaume Allorent

This study identifies LHL4 as a photoprotective protein in Chlamydomonas reinhardtii that prevents photodamage to photosystem II by binding its monomeric form and reducing singlet oxygen accumulation.

Photoreceptor-induced sinapate synthesis contributes to photoprotection in Arabidopsis

Manuela Leonardelli, Nicolas Tissot, Roman Podolec, Florence Ares-Orpel, Gaétan Glauser, Roman Ulm, Emilie Demarsy

This study shows that photoreceptors induce FAH1 to produce sinapate esters, which protect Arabidopsis from UV damage by acting as sunscreen compounds.
