Summary: The study showed that exposure to high light during the yellowing stage led to photooxidation in mutant 812HS leaves, while using a dark cover during the recovery stage restored green color. Additionally, mutant 812HS had decreased net photosynthetic rate and pigment content during the yellowing stage.

Summary: The study found that the photochemistry of PSII and PSI is primarily regulated by the amount of total leaf-N, with a strong correlation between the changes in PSII and PSI parameters, indicating a coordinated regulation. Additionally, in low N-acclimated plants, excess light energy was found to stimulate the oxidation of the reaction center chlorophyll of PSI to protect it, and the relationship between Y(II) and Y(ND) was similar to that observed in osmotically stressed rice plants.

Summary: The PSII of the light-sensitive albino tea plant is more vulnerable to high-light stress, which leads to the degradation of PSII subunits and disruption of light-harvesting chlorophyll-protein complexes, resulting in leaf bleaching. The de novo synthesis and repair of PSII subunits are involved in the impairment of PSII complexes, leading to the albino phenotype in the tea plant.

Summary: Plants have developed various mechanisms to deal with different types of light stress, with the regulation of the electron transport chain being particularly important. The cytochrome b6/f complex plays a crucial role in regulating the electron transport chain under high light conditions. The study reveals that thylakoid-localized cyclophilin 37 (CYP37) maintains the activity of the cytochrome b6/f complex in Arabidopsis. The interaction between CYP37 and photosynthetic electron transfer A (PetA) indicates that CYP37 functions as a maintenance factor of the cytochrome b6/f complex rather than an assembly factor.

Summary: In this study, it was found that in dark-adapted rice leaves, the light-harvesting complex II (LHCII) becomes phosphorylated and forms supercomplexes under low light conditions, which transition to aggregates under high light conditions. Knockout mutants of protein phosphatase 1 (PPH1) failed to form these LHCII aggregates, indicating their role in dissipating excess light energy. The aggregation of dephosphorylated LHCII in LHCII-PSI-LHCI supercomplexes was proposed as a newly observed photoprotective process in early HL acclimation in rice plants.

Summary: Tibet-0, a type of Arabidopsis thaliana collected from the Qinghai-Tibet Plateau, shows higher photosynthetic efficiency under high-light conditions compared to plants from lower altitudes. This is attributed to enhanced PSII activity, increased abundance of PSII complexes and subunits, and activated expression of chloroplast ribosomal protein-related genes in Tibet-0. These findings indicate that high-altitude plants have evolved mechanisms for enhanced photoprotection and efficient translation of PSII proteins in response to high-light environments.

Summary: Photosystem II (PSII) is a large membrane protein complex involved in primary charge separation in oxygenic photosynthesis. The assembly of PSII involves different modules that contain chlorophyll-binding proteins, membrane polypeptides, pigments and cofactors. Psb35 protein, identified in the CP47 antenna module, plays a crucial role in the accumulation and stability of chlorophyll-binding proteins.

Summary: The light-sensitive albino tea plant can gradually recover its photosynthetic pigments, chloroplast ultrastructure, and photosynthesis parameters from pale yellow to green through short-term shading treatment. This is attributed to the proper formation of pigment-protein complexes on the thylakoid membrane, benefiting from increased levels of LHCII subunits, particularly the deficiency of Lhcb1, in the shaded leaves of 'HJY'.

Summary: The behavior of photosystems II and I in rice leaves is modulated by changes in nitrogen partitioning, leading to alterations in how excess light energy is utilized. This study explores the changes in biochemical parameters of photosynthesis and their correlation with PSII and PSI parameters in mature and senescent leaves of rice under nitrogen deficiency.

Summary: This study investigated the role of thylakoid protein phosphorylation in regulating energy-dependent quenching of chlorophyll fluorescence in rice plants. The results showed that phosphorylated proteins were enhanced in the PsbS-KO mutant after illumination, indicating a light-induced process. It was suggested that this enhancement might be due to increased reactive-oxygen-species production in this mutant.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
