Summary: The overexpression of photoprotective proteins in the det1-2 phot mutant of green algae enhances the nonphotochemical quenching (NPQ) response, allowing the mutant to grow and survive under high light intensities that are lethal for wild-type cells. This mutant exhibits a smaller PSII cross-section and a detachment of LHCII antenna in the NPQ state. The study reveals the mechanism by which the overexpression of photoprotective proteins enables an efficient and effective photoprotective response in the det1-2 phot mutant.

Summary: Wound-induced signals not only cause physiological changes in locally damaged tissues, but also propagate to distal organs to elicit a systemic response. This review summarizes current knowledge on local and systemic responses to wounds in plants, with a focus on how wound-activated ion channels and pumps transmit information about injury and induce molecular responses in distal tissues.

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: Structures and simulations reveal the unique permeation mechanism of the human lysosomal K+ channel transmembrane protein 175 (TMEM175), which lacks the canonical K+ selectivity filter. Despite the absence of a selectivity filter, TMEM175 is selective for K+ over Na+ due to a narrow hydrophobic constriction and a favorable electrostatic field.

Summary: The water environment influences the activity of biological processes, with membrane proteins experiencing a change in hydrophobicity distribution when transitioning from a polar to a hydrophobic environment. The fuzzy oil drop model is utilized to interpret the structure of membrane proteins and describe both positive and negative cases involving protein behavior in different environments.

Summary: In this study, it was found that chromone-containing allylmorpholines can influence ion channels formed by pore-forming antibiotics in model lipid membranes. This is correlated with their ability to affect membrane boundary potential and lipid-packing stress. The compounds decrease the boundary potential and dipole potential of the lipid bilayers, as well as impact the thermotropic behavior and melting temperature of the lipids. These changes enhance the conductance of the ion channels and potentiate the pore-forming ability of the antibiotics.

Summary: This study demonstrates the integration of ordered two-dimensional covalent organic frameworks (2D COFs) into solid-state nanofluidic channels for rapid, selective, and sensitive detection of contaminants. The JNU-3@AAO-based nanofluidic sensor allows for ultrafast and precise determination of Hg(II), with a low limit of detection, wide linear range, and good precision. The developed method is also successfully applied to the determination of mercury in complex samples.

Summary: This study reveals that the Arabidopsis MSL10 channel is associated and functions with proteins at endoplasmic reticulum-plasma membrane contact sites (EPCSs). Mutations in the synaptotagmin genes were identified as suppressors of MSL10 gain-of-function phenotype. In addition, the expansion of EPCSs in msl10-3G plants provides new insights into the function and regulation of this subcellular compartment.

Summary: The contraction of heart cells is regulated by the signaling interaction between LCCs and RyRs, which is influenced by the nanodistance between JPH2 in the SR and CAV3 in the TT. Our study revealed that SRF and myocardin concurrently regulate the expression of JPH2 and CAV3, leading to enhanced efficiency of LCC-RyR signaling and compensation for LCC down-regulation during hibernation, maintaining heart power and avoiding calcium overload.

Summary: The study explored the mechanisms of plant response to local burn and gradual heating stress. It was found that burn-induced response attenuated with distance, while heating-induced response remained stable in distant parts of the plant. The differences observed in systemic response may reflect distinct plant adaptation strategies to fast and slow-growing stimuli, with immediate tissue response being crucial for fast-growing stress while long-term changes prepare the plant for impending environmental changes under slow-growing stimulus.

Summary: This study investigated the mechanisms of plant response to local burn and gradual heating, revealing differences in the response induced by different stimuli. The systemic response to stressors reflects distinct plant adaptation strategies to fast and slow-growing stimuli, with burn-induced response attenuating with distance and heating-induced response being more stable in distant parts.

Summary: In this study, eco-geopolymer building materials based on class F fly ashes were developed and tested for their ability to act as a barrier against radioactive radiation. The results showed that higher SiO2 content in the fly ashes led to increased surface area and reactivity. Lower activator concentration and curing temperature resulted in improved compressive strength of the GPBMs. Additionally, a mathematical model confirmed the significance of fly ash quantity on the mechanical properties of the GPBMs.

Summary: Irreversible climate change is a crucial issue of our time, and the construction industry needs to find solutions to improve energy efficiency in buildings. This paper introduces a foamed geopolymer material based on metakaolin, which can be used as a modern facade material. By modifying the composition of the geopolymer with organic substances, such as perlite and cellulose fibers, the thermal insulation properties have been improved. The study demonstrates that the final properties of the foamed geopolymer can be controlled through modifications, which determine its suitability for applications.

Summary: This study demonstrates the potential of using 3D printing technology to produce concrete-geopolymer hybrids reinforced with aramid roving, and compares the performance of samples in terms of frost resistance, UV radiation resistance, and thermal conductivity. The results show that 3D-printed samples had slightly decreased strength properties after frost resistance tests compared to samples made by conventional casting, and concrete-geopolymer hybrids had higher thermal conductivity coefficient than concrete reinforced with aramid roving.

Summary: Production of biofuel from lignocellulosic biomass is currently limited by the lack of knowledge about plant cell wall loosening and cellulolytic processes. This study explores the potential of cell death in reducing the recalcitrance of lignocellulose for bioethanol production. Transgenic aspen trees with suppressed cell death regulatory genes showed reduced lignin content, increased cellulose fiber polymerization degree, and improved efficiency in saccharification, alcoholic fermentation, and bioethanol production.
