Photoreceptor-induced sinapate synthesis contributes to photoprotection in Arabidopsis

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

Photoreceptor-induced LHL4 protects photosystem II in Chlamydomonas reinhardtii

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.

Sensory perception of fluctuating light in 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.

The UV RESISTANCE LOCUS 8-Mediated UV-B Response Is Required Alongside CRYPTOCHROME1 For Plant Survival Under Sunlight In The Field

This study shows that UVR8 and CRY1 work together in Arabidopsis to help plants survive UV-B radiation in natural conditions, with UVR8 playing a key role in long-term survival.

BBX proteins promote HY5-mediated UVR8 signaling in Arabidopsis

This study shows BBX20-22 proteins enhance HY5 activity in UV-B responses by stabilizing HY5 through UVR8-dependent mechanisms.

Dual control of MAPK activities by AP2C1 and MKP1 MAPK phosphatases regulates defence responses in Arabidopsis

This study shows that AP2C1 and MKP1 phosphatases regulate MAPK activity in Arabidopsis, preventing autoimmune-like stress responses by controlling MPK6.

A constitutively monomeric UVR8 photoreceptor allele confers enhanced UV-B photomorphogenesis

The paper describes a hyperactive UVR8 allele that causes constitutive photomorphogenesis and enhanced UV-B responsiveness due to impaired dimerization and inactivation.

Plant photoreceptors and their signaling components compete for binding to the ubiquitin ligase COP1 using their VP-peptide motifs

The paper shows that photoreceptors and transcription factors compete for COP1 binding via VP-peptide motifs, controlling light signaling in plants.
