Ultrafast energy quenching mechanism of LHCSR3-dependent photoprotection in Chlamydomonas

Nature Communications
Photosynthetic organisms have evolved an essential energy-dependent quenching (qE) mechanism to avoid any lethal damages caused by high light. While the triggering mechanism of qE has been well addressed, candidates for quenchers are often debated.

Far-red Fraction: An Improved Metric for Characterizing Phytochrome Effects on Morphology

Journal of the American Society for Horticultural Science, 2020
Phytochrome, a well-studied photoreceptor in plants, primarily absorbs in the red (R) and far-red (FR) regions and is responsible for the perception of shade and subsequent morphological responses.

Weak acids produced during anaerobic respiration suppress both photosynthesis and aerobic respiration

Nature Communications, 2023
While photosynthesis transforms sunlight energy into sugar, aerobic and anaerobic respiration (fermentation) catabolizes sugars to fuel cellular activities.

Transcription factors interact with Arabidopsis UVR8 photoreceptor at distinct sites to COP1 and RUP proteins

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Many responses of plants to UV‐B radiation are mediated by the UVR8 photoreceptor. UVR8 functions by interacting directly with various proteins. In particular, binding of transcription factors to UVR8 modifies their ability to regulate sets of genes involved in specific responses to UV‐B.

Structure and distinct supramolecular organization of a PSII-ACPII dimer from a cryptophyte alga Chroomonas placoidea

Nature Communications
Cryptophyte algae are an evolutionarily distinct and ecologically important group of photosynthetic unicellular eukaryotes. Photosystem II (PSII) of cryptophyte algae associates with alloxanthin chlorophyll a/c-binding proteins (ACPs) to act as the ...

The Photoreceptor Components FaWC1 and FaWC2 of Fusarium asiaticum Cooperatively Regulate Light Responses but Play Independent Roles in Virulence Expression

Microorganisms, 2020
Fusarium asiaticum belongs to one of the phylogenetical subgroups of the F. graminearum species complex and is epidemically predominant in the East Asia area. The life cycle of F. asiaticum is significantly regulated by light.

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

New Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Optical Properties of Living Corals Determined With Diffuse Reflectance Spectroscopy

Frontiers in Marine Science, 2019
The internal light field and thus light exposure of the photosymbiotic microalgae (Symbiodinium sp.) in corals is strongly modulated by the optical properties of coral tissue and skeleton.

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

Advanced Science, Volume 13, Issue 29, 22 May 2026.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Global consensus on the management of melanin hyperpigmentation disorders

Journal of the European Academy of Dermatology and Venereology, Volume 40, Issue 5, Page 760-772, May 2026.
A global Delphi consensus of 10 dermatology experts established evidence‐based recommendations for melanin hyperpigmentation disorders, providing unified classification, photoprotection guidance and treatment algorithms. This framework harmonizes terminology and supports individualized management across diverse skin types and health systems.
