Summary: The study found that the increase in atmospheric carbon dioxide concentration can alleviate the inhibition of hazelnut growth under cadmium pollution. It also enhances the photosynthetic capacity and improves the function of the photosystem II in hazelnut leaves. This increase in carbon dioxide concentration improves hazelnut's resistance to cadmium stress.

Summary: The temporal and spatial heterogeneity of chlorophyll content and fluorescence in rice canopy leaves under different Cd stress concentrations was explored in this study. The responses of relative chlorophyll content (SPAD) and chlorophyll fluorescence (ChlF) parameters to Cd stress in different growth stages were analyzed. It was found that lower leaves had higher SPAD values in the tillering stage, while upper leaves had higher SPAD values in the heading and filling stages. Certain ChlF parameters were more sensitive to Cd stress than others.

Summary: The research examines the effects of sub-optimal illumination on three plant species by studying chlorophyll fluorescence. The findings show that low light treatment increases pigment content and maintains fluorescence ratios, suggesting conservation of photosystems stoichiometry. Different plant species respond differently to low light, with L. sativa adapting, A. hybridus not significantly stressed, and S. dendroideum decreasing antenna size but increasing quantum yield of primary photochemistry.

Summary: This study investigated the effect of melatonin pretreatment on chlorophyll synthesis and fluorescence parameters in Malva parviflora exposed to cadmium (Cd). The results showed that melatonin increased chlorophyll content and improved the photochemical efficiency of PsbO by reducing the toxic effect of Cd and non-photochemical quenching. These findings provide insights into the mechanism underlying the improved yield and growth of Cd-exposed plants when pretreated with melatonin.

Summary: Soil contamination by heavy metals poses a significant environmental challenge. This study investigated the potential of nitric oxide (NO) to reduce cadmium (Cd) toxicity in A. annua plants. Results showed that NO effectively reversed Cd-induced damage by modulating the antioxidant system and improving photosynthetic performance. The supplementation of NO also increased artemisinin production, highlighting its potential role in mitigating the negative impacts of environmental contaminants on plant health.

Summary: The study analyzed metal elements in the Antarctic plant Colobanthus quitensis, finding higher concentrations in areas with more human activity and lower concentrations in areas with minimal human intervention. The order of metal concentrations in plant tissues was similar across all sampling locations, while in soil it differed slightly, indicating that the area in Antarctica was non-polluted. However, the presence of metallic trace elements (MTE) at early stages of contamination poses a new threat to this continent, as seen in other areas of Antarctica.

Summary: This study investigated the antifouling effect of copper oxide (Cu2O)- and zineb-based coatings on Cyanothece sp. ATCC 51142 by analyzing chlorophyll fluorescence. It was found that Cyanothece cultures are sensitive to biocides released from antifouling paints and exhibited by contact with the coated surfaces. The maximum quantum yield of photosystem II (F-V/F-M) changed within the first 12 hours of exposure, and partial recovery was observed 24 hours after exposure to a copper- and zineb-free coating.

Summary: The study investigated the sensitivity of the Antarctic moss Sanionia uncinata from King George Island and James Ross Island to photoinhibitory treatment in laboratory conditions. The results showed that both samples exhibited slight photoinhibition after exposure, with quick recovery to pre-treatment levels. Additionally, the moss samples from King George Island demonstrated higher resistance to photoinhibition compared to those from James Ross Island.

Summary: This study investigates the effects of different concentrations of lead pollution on the growth and photosynthetic characteristics of Miscanthus floridulus. Through nutrient solution culture experiments, the gas exchange parameters, chlorophyll fluorescence characteristics, and photosynthetic pigment of two populations of Miscanthus floridulus from uncontaminated and mine sites were compared. The results show that the mine population exhibits a higher tolerance to lead stress, with a smaller decrease in photosynthetic rate and a higher potential to activate photosystem II (PSII). Hence, the mine population is suitable for vegetation restoration in metal mining areas.

Summary: In the future, space telescopes will investigate the Galaxy to search for evidence of life, with a focus on rocky planets and M dwarf-hosted super-Earths. Recent studies have found cyanobacteria capable of utilizing far-red light for photosynthesis, indicating the potential for exotic photosynthesis on planets around M dwarfs. Evaluating the photosynthetic performances of oxygenic organisms under such conditions highlights the importance of simulating both visible and far-red light components of an M dwarf spectrum.

Summary: Eukaryotic algae, including red algae, have the ability to use sunlight to fix carbon dioxide into biomass. Despite the diversity of algae metabolism, information on red algae is relatively scarce. This study focuses on the photosynthetic properties of a recently isolated mesophilic red algae and found that these cells are capable of acclimating, regulating chlorophyll content, and reorganizing thylakoid membranes under different light conditions.

Summary: The study suggests that stem photosynthesis plays an adaptive role in woody plants that thrive in hot and dry ecosystems, aiding in their resistance to water shortage. The efficiency of stem photosynthesis was found to be higher in drought-tolerant species compared to drought-sensitive species, potentially leading to prolonged stomatal closure and cessation of carbon gain at the leaf level.

Summary: Leaves are the primary photosynthetic organs for most woody plants, but chloroplasts are also present in organs optimized for other functions. The efficiency of these chloroplasts is still unclear. In this study, we analyzed the chloroplasts in bark and wood of Fraxinus ornus saplings and found that despite receiving less light, wood chloroplasts were still capable of photosynthesis. The stem photosynthetic apparatus showed adaptations to low-light environments.
