This study identifies a minimal C-terminal targeting motif for plant catalases that enables their peroxisomal import in Arabidopsis.

This study identifies CAIR1 as a redox-regulated protein that enhances catalase activity in Arabidopsis by facilitating its peroxisomal import and subcellular localization.

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

The paper shows that Arabidopsis thaliana detects low-frequency sunflecks through phytochrome B, cryptochromes, and UVR8, leading to growth adjustments and gene expression changes.

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.

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