Summary: Tropospheric ozone pollution has reached phytotoxic levels and is expected to continue to be a major concern in the future. Despite similar injury processes, there is considerable variability in foliar symptoms, which may be influenced by spatial and temporal dynamics. This study investigated the changes in cell structure occurring in the mesophyll as a response to ozone treatment, time, phytotoxic ozone dose, leaf developmental stage, and mesophyll layer. The results suggest that early hypersensitive response-like markers can provide reliable estimates of ozone stress, especially if they are associated with degenerative and thylakoid-related injury in chloroplasts from mesophyll.

Summary: Mitogen-activated protein kinase (MAPK) cascades are crucial in plant biological processes. Besides the traditional phosphorylation pathway, there are other regulatory mechanisms of plant MAPK cascades. MAPK kinase kinases (MAPKKKs) play an unusual role in the regulation of MAPK cascades, and their non-MAPKKK function needs further investigation.

Summary: Agricultural non-point source pollution, characterized by dispersion and uncertainty, poses great threat to agricultural water ecosystem. In this study, a ZVI/CaO2 system was constructed to collaboratively remove typical pollutants, such as P, Pb, and ATZ. The removal efficiencies of these pollutants were high, and the main active species in the system was identified as hydroxyl radicals. The pollutants were effectively removed through precipitation, adsorption, and degradation.

Summary: Activated carbon injection is an effective method for removing organic pollutants from coal-fired power plants, with aromatic hydrocarbons and oxygenated volatile organic compounds being the major components. The removal efficiency of organic pollutants is influenced by their physicochemical properties, and increasing the amount of AC injection can enhance the adsorption effect but decrease the adsorption capacity.

Summary: Microbial communities in wastewater treatment plants (WWTPs) are crucial for water purification. This study analyzed the microbial communities of activated sludge (AS) in nine large-scale WWTPs in Moscow, Russia, revealing that the composition of microbial communities varied depending on the plant operating technology. The WWTPs using the University of Cape Town (UCT) process showed efficient removal of organic matter, nitrogen, and phosphorus, possibly due to the presence of specific bacteria. Co-occurrence network analysis identified key microorganisms in AS, which could be targeted to manipulate the stability and performance of the AS. Comparison with WWTPs worldwide indicated that influent characteristics related to social, cultural, and environmental factors may be more important than the plant operating technology.

Summary: The study evaluated the agronomic efficiency of activated rock phosphate (RP) fertilizers on maize growth with or without mycorrhizal inoculation. Results showed that activated RP, by increasing phosphorus (P) availability, enhanced maize N and P uptake, biomass, and relative agronomic efficiency (RAE) at levels equivalent to diammonium phosphate (DAP). Mycorrhizal inoculation did not affect these properties. Further research is needed to investigate the mechanism behind RP activation to promote the utilization of small-scale RP deposits.

Summary: This study examined the presence of microplastics in the sludge of three wastewater treatment plants. The findings showed that microplastics were transferred and concentrated in the waste sludge, with different shapes and compositions observed in different treatment processes. This is an important discovery as sludge disposal could become a new pathway for microplastic release into the environment.

Summary: This paper evaluates linear and nonlinear regression analysis for describing adsorption kinetics. Pseudo-first-order (PFO) and pseudo-second-order (PSO) models are used, and the accuracy of nonlinear regression analysis is found to be better than linearization. Correlation coefficient, Chi-square, and residual plot analysis are used to choose the appropriate model and validate the results. The models are then employed to reevaluate experimental data on various adsorption processes, suggesting that mixed models and a large number of data points improve the kinetic modeling.

Summary: The study investigates the contributions of coal-fired plants and coal-burning households to critical pollutants and finds that the concentrations of PM10, PM2.5, SO2, NO2, and O-3 exceed national and international standards. PM10 and PM2.5 are mainly generated within the community, while NO2 seems to receive significant contributions from biogenic emissions and SO2 and O-3 may come from coal-fired plants.

Summary: While human EVs have been extensively studied, plant-derived EVs have received less attention. This study introduces plant cell suspension culture as a new source for plant EVs and nanovesicles, revealing properties and mechanisms similar to animal cell-derived exosomes and microvesicles. Proteins present in plant EVs indicate potential mechanisms for cell wall passage and suggest similarities in EV secretion mechanisms between plant and animal cells.

Summary: The resurrection species Craterostigma plantagineum possesses remarkable desiccation tolerance due to its unique cell wall folding mechanism, allowing ordered and reversible shrinking of cells. Research using inhibitors affecting cellulose biosynthesis has advanced understanding of compensatory mechanisms. Gene expression and protein abundance in habituated cells did not follow the same trend, suggesting alterations in auxin levels may be responsible for changes in cell wall-related proteins.

Summary: This study investigated the molecular events and gene expression changes associated with russeting in apple skin. Using metabolomics, proteomics, and transcriptomics data, the study revealed lower expression of cuticle biosynthesis genes and alteration of specialized metabolism pathways in russet apple. A lipid transfer protein was identified as a novel player in cuticle formation, and a diverse range of triterpene-hydroxycinnamates were found to accumulate in russeted tissues. This study enhances our understanding of the interaction between triterpene and suberin pathways.

Summary: This study evaluates the modulation of grapevine proteome in the apoplast during the first 6 hours after Plasmopara viticola inoculation, revealing the dynamics of cellular communication between grapevine and the pathogen. The results showed that the tolerant grapevine cultivar triggers defense mechanisms such as pathogen recognition, cell wall modifications, reactive oxygen species signaling, and secretion of proteins to disrupt pathogen structures. Meanwhile, the pathogen proteins related to development and virulence were found to be predominant. This pioneer study highlights the significance of early cellular communication in grapevine defense.

Summary: Drought stress has a negative impact on edible vegetable production globally, including economically important crops such as common bean (Phaseolus vulgaris L.) that heavily rely on rainfall or irrigation. This study summarized phenotypic data of 26 Bulgarian common bean mutant lines and cultivars exposed to drought stress, and evaluated the drought stress response using chlorophyll fluorescence and proteomics approaches. Different responses were observed among the mutant lines as several basic photosynthetic parameters were examined. Additionally, a relationship was found between productivity and photosynthetic performance, as well as the expression of key proteins related to stress response. These findings provide support for the selection of drought tolerant common bean lines for sustainable agriculture.
