Summary: Nitrogen pollution and excessive salinity are major environmental concerns in urban environments. This study explores the simultaneous impact and interaction of salt and nitrogen stress on lichen physiology. The results show significant disturbances in cell membrane integrity and chlorophyll fluorescence parameters. Lichens from polluted sites and previously affected by harmful factors exhibit stronger responses to stress. This has implications for lichens in urban environments, particularly those near roads.

Summary: This study focused on PSII heterogeneity in two sugarcane cultivars under chilling stress, revealing that chilling stress negatively affects PSII performance, particularly in Guitang 49. The results suggest that PSII heterogeneity can be utilized as a novel technique for evaluating plant responses to environmental stress.

Summary: The study investigated the effects of different NaCl concentrations on the photosynthesis of maize and sorghum, revealing stronger impacts in maize compared to sorghum at certain NaCl concentrations. The changes in primary PSII photochemistry influenced the electron transport rate and photosynthetic rate, with maize showing stronger effects. Additionally, sorghum exhibited better salt tolerance at higher NaCl concentrations, associated with structural alterations in photosynthetic membranes and stimulation of cyclic electron flow around PSI.

Summary: Salt stress significantly impairs the photosynthetic efficiency of lichens, primarily due to ionic effects. Ionic stress reduces the utilization of energy in electron transport, leading to down-regulation of electron transfer. Hypogymnia physodes is more sensitive to salt stress than Pseudevernia furfuracea. Repeated exposure to salt in the winter season may reduce the vitality of lichens.

Summary: The impacts of different sodium nitroprusside (SNP) concentrations on two sorghum varieties under salt stress were investigated in this study. Salinity led to oxidative stress, damage of membrane integrity, and a decrease in chlorophyll content and photosynthetic performance. SNP application alleviated the toxicity of salt stress on photosynthetic functions, with a greater effect observed in one sorghum variety. The degree of SNP protection depended on endogenous nitric oxide levels, active reaction centers, and electron flux around photosystem I.

Summary: Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942 exhibit different tolerance to Cr(VI) and show differential responses in photosynthesis under Cr(VI) exposure. Despite being exposed to a lower concentration of Cr(VI), Synechocystis had more severely impaired photosynthetic functions compared to Synechococcus.

Summary: Photosystem stability and cooperation in halophytic shrub wolfberry were investigated under salt stress. Results showed that wolfberry exhibited high tolerance of photosystems under 200 mM NaCl stress, but suffered significant photoinhibition in both PSII and PSI under 300 mM NaCl stress, with PSI being more severely damaged.

Summary: This study aimed to evaluate the sustainability of bio-priming salt tolerant endophytes for improving plant salt tolerance. Results indicate that Trichoderma hamatum significantly increased the growth and chlorophyll content of crops, and reduced oxidative stress levels. Infrared thermographic images also showed that bio-primed plants were resistant to salt stress.

Summary: In this study, the individual and combined effects of drought and heat stress on key physiological parameters in two sorghum cultivars during the seedling stage were investigated. The stress responses of sorghum cultivars were effectively differentiated using pixel-wise analysis of thermal images. The combined stress of drought and heat had a more adverse impact than their individual effects, and a drought-tolerant variety was less affected. The methodology of measuring and reporting plant canopy temperature can effectively differentiate sorghum genotypes under combined stress.

Summary: Jerusalem artichoke showed vulnerabilities in both PSII and PSI under salt stress. The inactivation of PSII, a passive consequence of PSI photoinhibition, hardly helped protect PSI.

Summary: Decreased phosphatidylglycerol levels in the pgp1 mutant limit the ability to maintain photosynthetic activity during cold acclimation, resulting in abnormal chloroplast structure and function, while normal levels of phosphatidylglycerol are essential for stabilizing the photosynthetic apparatus.

Summary: The study investigated the fluorescence emission characteristics of photosystems in the pennate diatom, revealing that the F710 fluorescence originates from Photosystem I and is enhanced in cells grown under intermittent light. This enhancement is likely due to increased energy flow from the FCP antenna to Photosystem I.
