This study shows that NDH is essential for protecting PSI from chilling-induced photoinhibition in rice and cucumber, and that chilling destabilizes the PSI-NDH supercomplex.

The paper develops a wearable Sensor-PAM system for continuous chlorophyll fluorescence monitoring of photosynthetic dynamics in plants, showing strong correlation with conventional measurements and real-time response tracking.

The paper uses imaging-pulse-amplitude-modulation to analyze tissue-specific photosynthetic responses in living leaves, revealing spatial organization of photochemical properties according to leaf anatomy.

This study identifies Lhcf2 as essential for energy-dependent NPQ in diatoms by enabling Lhcx1 accumulation and function.

This study examines the structure-activity relationship of antimycin A-like compounds on photosystem II, identifying key structural features and proposing tentative binding models.

This study shows that PIFI stabilizes the NDH-PSI supercomplex, maintaining plastoquinone redox balance and PSII efficiency in chloroplasts.

This paper identifies CgLhcf9 as a negative regulator of energy-dependent NPQ in the diatom Chaetoceros gracilis, showing it suppresses NPQ under specific light and CO2 conditions to improve growth.

This study shows that marine diatoms redistribute excitation energy between photosystems I and II under different light conditions, using distinct strategies in two species.

This study shows that antimycin A directly suppresses photosystem II activity, unlike antimycin A3 or myxothiazol, and recommends using AA3 and myxothiazol for specific pathways.

This study identifies chloroplast NADH dehydrogenase-like complex (NDH) as a protective factor against PSI photoinhibition under chilling stress by comparing two cucumber cultivars.

This study identifies the evolutionary origin of Lhcx in diatoms and shows its role in photoprotection through non-photochemical quenching.

This study shows that PSII photoinhibition protects PSI from photoinhibition and ROS damage under environmental stress in plants.

This study shows that antimycin A directly affects photosystem II and causes photoinhibition, suggesting it is not a specific inhibitor of PGR5-dependent CEF-PSI.

This study investigates the evolutionary changes in LHCI structures across red-lineage algae, identifying conserved and diversified Lhcr groups and introducing the concept of neolocalization.

The paper determines the cryo-EM structure of a diatom PSI-FCPI supercomplex, identifies FCPI subunits, and reveals protein-protein interactions and evolutionary conservation of binding motifs.
