Summary: The study found that the German Baltic Sea coastline is characterized by sea-land transition zones with highly fluctuating environmental parameters, affecting the physiological processes of inhabiting organisms. Benthic diatom strains exhibited wide adaptability in terms of light, temperature, and salinity, with no growth rate differences between peatland and Baltic Sea strains. The photosynthetic temperature optimum of peatland diatom isolates was higher compared to Baltic Sea isolates.

Summary: Photochemical energy conversion in oxygenic photosynthesis relies on membrane-embedded chlorophyll-binding protein complexes, which are regulated by lipoproteins such as Ycf48. Ycf48, a lipoprotein assembly factor in cyanobacteria, plays a crucial role in the biogenesis and function of the photosystem II complex. The unique lipobox sequence in Ycf48 distinguishes it from canonical lipobox sequences and highlights its importance in cyanobacterial PSII assembly.

Summary: Photosystem II (PSII) is a fascinating enzyme involved in photosynthesis that can be coupled with synthetic structures through biomimetic assembly to mimic natural processes. This approach helps gather functions and properties from synthetic materials, inspiring semi-biohybrid research and optimization of artificial light-harvest micro/nanodevices. The combination of PSII with artificial structures offers opportunities for developing biomimetic semi-natural devices and unlocking the secrets of energy conversion in natural photosynthesis.

Summary: In a long-term salt-stress experiment, the commercial sweet pepper cultivar showed higher tolerance to the detriment of PSII structure and function compared to the landrace, with the performance index decreasing earlier than the maximum quantum yield of PSII. PSII was more affected than PSI, but PSI functionality recovered in the late phase of the trial.

Summary: The use of LED technology can improve plant growth and metabolic activities. Different light spectra have different effects on biochemical properties, photosynthesis, and gene expression in lettuce cultivars. The red/blue LED and red LED light treatments with complete replacement or EC-based replacement of nutrient solution increased proline and soluble sugars content, as well as activity of antioxidant enzymes in both cultivars. Red/blue light had the greatest induction effect on anthocyanin content, expression of specific genes, and net photosynthetic rate. These findings contribute to the development of strategies to improve plant growth and metabolism, reduce waste, and prevent pollution.

Summary: Wood vinegar is commonly used in agriculture as organic fertilizer and antibacterial agent. This research study shows that pretreatment of wood vinegar can alleviate the inhibitory effects of salt stress on rapeseed cultivation by promoting plant growth, improving photosynthetic efficiency, and maintaining redox balance. The protective mechanism of wood vinegar involves reducing oxidative stress, lipid peroxidation, and improving antioxidant enzyme activities. Furthermore, wood vinegar also regulates the expression of salt transporter genes and reduces the uptake of Na+ in plants under salt stress. This study provides valuable insights into the interaction between wood vinegar and ion homeostasis in plants under salinity stress.

Summary: Recent advances in understanding the origin and evolution of photosystem II are reviewed and discussed, revealing that water oxidation occurred early in the history of life. Photosystem II has remained relatively unchanged for billions of years, but constant duplication of the D1 subunit has allowed the enzyme to adapt to different environments and even develop enzymatic functions beyond water oxidation. This adaptability could be utilized to develop novel light-powered enzymes for sustainable biocatalysis.

Summary: This study aimed to investigate the effects of NaCl salinity stress on chlorophyll fluorescence, nutrient uptake, and physiological characteristics of different mint species. The results showed that mint ecotypes E14, E10, and E18 were the most tolerant, displaying a high Fv/Fm index at all salinity levels. Salinity conditions can significantly impact the physiological processes and defense pathways of mint plants, resulting in dramatic changes in plant nutrients, photosynthesis efficiency, and essential oil content.

Summary: The study demonstrated that glycinebetaine (GB) can enhance chilling tolerance in tomato plants by protecting chloroplast ultrastructure, mitigating PSII photoinhibition, and maintaining PSII stability under chilling stress. GB also increased electron transfer rate and cyclic electron flow, reduced reactive oxygen species production, and alleviated PSI photodamage. Introduction of the GB biosynthetic pathway and exogenous GB application are effective strategies for improving chilling tolerance in tomato plants.

Summary: Experimental systems simulating future elevated CO2 conditions often have fluctuating CO2, which can reduce photosynthesis by decreasing stomatal conductance and the photochemical efficiency of photosystem II. However, the impact of CO2 fluctuations varies among different species, with some showing no change in photosynthesis and stomatal conductance.

Summary: The study found that polyploids of Dianthus broteri (especially the 6x and 12x) showed higher divergence in leaf economics spectrum (LES) and soil niche traits compared to diploids, but these traits were not coevolving. The 6x and 12x exhibited contrasting ecological strategies in resource use, with a higher uncoupling of the LES network. Early trait divergence prevailed in both LES and soil niche, with post-polyploidization processes playing a significant role in photochemical behavior.

Summary: Amid climate change, heatwave events are expected to increase in frequency and severity. The present work aims to evaluate the physiological fitness improvement by two marine plant growth-promoting rhizobacteria consortia in Vitis vinifera cv. Antao Vaz under heatwave conditions. Bioaugmented grapevines exposed to heatwave stress presented a significantly enhanced photoprotection capability and higher thermo-stability, exhibiting a significantly lower dissipation energy flux than the non-inoculated plants. Additionally, one of the rhizobacterial consortia tested improved light-harvesting capabilities and osmoprotectant promotion, resulting in lower osmolyte concentration and maintained leaf turgidity.

Summary: In this study, the combined effect of increased temperature and atmospheric CO2, salt and drought stress, and PGPR inoculation on the growth and nutritional parameters of Salicornia ramosissima, an edible halophyte, was investigated. It was found that these stressors led to significant changes in fatty acids, phenols, and oxalate contents of S. ramosissima, which are important compounds for human health. Results suggest that in future climate change scenarios, there will be alterations in the lipid profile and levels of oxalate and phenolic compounds in S. ramosissima due to temperature, CO2, and salt and drought stress. The effect of PGPR inoculation depended on the strains used, with some strains inducing the accumulation of phenols and oxalate. This study highlights the potential for nutritional and economic valorization of S. ramosissima in response to these stressors and environmental conditions.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
