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.

Diatom pyrenoids are encased in a protein shell that enables efficient CO2 fixation

This study identifies a protein shell surrounding diatom pyrenoids that enhances CO2 fixation efficiency and reveals its structural and functional role through in vivo and in vitro analyses.

Tailoring confocal microscopy for in-cell photophysiology studies

The paper develops a confocal microscopy approach to study single-cell photophysiology in plants and phytoplankton, revealing insights into photosynthetic specialization and light response mechanisms.

Impaired photoprotection in Phaeodactylum tricornutum KEA3 mutants reveals the proton regulatory circuit of diatoms light acclimation.

The paper identifies KEA3 as the main regulator of the PET/PMF relationship in diatoms, showing its role in modulating NPQ responses and light acclimation.

Photosynthetic light harvesting and thylakoid organization in a CRISPR/Cas9 Arabidopsis thaliana LHCB1 knockout mutant.

This study examines the effects of knocking out LHCB1 in Arabidopsis thaliana, showing reduced chlorophyll levels, altered photosystem absorption, and changes in thylakoid structure.

Photoprotection is regulated by light-independent CO2 availability

This study shows that CO2 availability, not light, directly regulates photoprotection and the CO2 concentrating mechanism in Chlamydomonas reinhardtii, with light indirectly influencing these processes by altering CO2 levels.

Subcellular architecture and metabolic connection in the planktonic photosymbiosis between Collodaria (radiolarians) and their microalgae

This study uses multimodal imaging to analyze subcellular changes and nutrient dynamics in the photosymbiosis between Collodaria and their microalgae, revealing metabolic adaptations and nutrient allocation patterns.

Cytoklepty in the plankton: a host strategy to optimize the bioenergetic machinery of endosymbiotic algae

The paper shows that host cells manipulate algal endosymbionts to enhance their bioenergetic machinery, leading to increased carbon uptake and photosynthetic efficiency.

In-cell quantitative structural imaging of phytoplankton using 3D electron microscopy

This paper develops a 3D electron microscopy workflow to generate nanometric phytoplankton models and identifies conserved subcellular features related to energy management.

Identification of the Calmodulin-dependent NAD+ kinase sustaining the elicitor-induced oxidative burst in plants

The paper identifies a CaM-dependent NAD+ kinase in plants that amplifies the oxidative burst in response to pathogen elicitors.
