Summary: The aim of this study was to observe the effect of ZnO nanoparticle (NP) and ZnO-NP + biochar on As and Zn accumulation in and growth of rice plants grown under flooded conditions. The results showed that ZnO-NP and ZnO-NP + biochar treatments significantly increased rice growth and yield, as well as total chlorophyll content. Additionally, the level of electrolytic leakage and MDA content decreased in treated plants, while As accumulation was reduced in rice grains and Zn accumulation increased in treated plants compared to the control. The findings highlight the importance of using ZnO-NP and biochar in flooded agricultural soil to improve growth, yield, and reduce As accumulation in rice plants.

Summary: The growth potential of three minor fruit species after exposure to different nickel levels was evaluated. The results showed that nickel exposure negatively affected biomass elongation and caused oxidative damage. However, one of the species exhibited resilience through restricted nickel transfer, adequate nutrient uptake, and enhanced antioxidant enzyme biosynthesis.

Summary: Salinity is a significant abiotic stressor that affects crop growth and yield. This study investigated the effects of different foliar sprays on tarragon under NaCl salinity conditions. The results showed that foliar spray with graphene improved the K+/Na+ ratio, zinc spray enhanced catalase activity, and both forms of iron and zinc partially alleviated the adverse effects of salinity on tarragon.

Summary: Mangrove-derived actinobacteria, such as Mycobacterium saopaulense, have a high potential to biosynthesize a variety of biologically active secondary metabolites, including antibiotics and bioactive compounds. Whole genome sequencing and mass spectrometry analysis of this strain revealed 81 gene clusters associated with the production of 23 secondary metabolites, among which clavulanic acid and streptomycin were identified during fermentation. This study highlights the importance of exploring the secondary metabolite production potential of actinobacteria sourced from mangroves.

Summary: The introduction of Kandelia candel promoted methane emissions in coastal wetland ecosystems. Nitrogen input significantly enhanced methane emissions in both planted and unplanted environments, with different contributions from Kandelia candel and soil microorganisms under various nitrogen concentrations.

Summary: In 2003, a new mangrove species, Kandelia obovata, was identified. This study compared the chloroplast (cp) genomes of Kandelia candel and Kandelia obovata and found that both species have 128 genes encoded in their cp genomes. However, Kandelia obovata has a larger cp genome size due to the presence of more and longer repeat sequences. These genome differences suggest possible adaptations to different environments separated by the South China Sea.

Summary: Soils contaminated with antibiotics can have adverse effects on soil-dwelling animals, as shown in a systematic ecological toxicity assessment of norfloxacin on the soil collembolan Folsomia candida. While norfloxacin had minimal impact on population and individual levels, antioxidant enzyme activities were significantly affected with longer exposure times or higher concentrations. Changes in gut microbiota diversity and composition were limited, but the presence of norfloxacin led to a decrease in operational taxonomic units in the gut and a reduction in the relative abundance of the predominant bacterial genus Wolbachia. Wolbachia may serve as a potential bioindicator for assessing norfloxacin pollution in soils at environmental concentrations.

Summary: This study aimed to investigate the influence of different polyphenolic antioxidant-rich beverages on five-a-side/futsal players. The results showed that oxidative stress markers significantly increased in the blood after the match, while the almond-based beverage supplemented group had significantly lower malondialdehyde levels in neutrophils compared to the control group. In conclusion, polyphenolic antioxidant and anti-inflammatory supplements could aid in optimal recovery after high-intensity futsal games.

Summary: This study evaluated drought tolerance in 18 eggplant accessions and 8 wild relatives, identifying accessions with higher drought tolerance based on dry matter content, proline concentration, and biochemical parameters. Tolerant materials such as S. incanum, S. pyracanthos, S. dasyphyllum, and S. torvum showed better performance in terms of oxidative stress and biochemical responses to water stress. The results suggest a high diversity in drought tolerance among eggplant wild relatives, providing insights for breeding programmes to develop new cultivars with higher drought tolerance.

Summary: This study investigated the effect of copper oxide nanoparticles (CuO NPs) on cadmium (Cd) accumulation in wheat plants. The results showed that CuO NPs improved the growth and physiology of wheat plants, reduced Cd content, and enhanced the uptake of essential nutrients. This can help reduce the health risks associated with excessive Cd exposure. However, further research is needed to explore different plant species and application methods of CuO NPs.

Summary: This study examined the growth and physiological responses of Kandelia obovata seedlings to different levels of arsenic (As) exposure. The results showed that the seedlings exhibited high tolerance to As exposure within a certain concentration range, with antioxidant enzymes playing a crucial role in resisting As toxicity. However, high concentrations of As inhibited seedling growth and led to increased malondialdehyde content and decreased antioxidant enzyme activities. It was also found that As mainly accumulated in the roots, and the translocation of As to the aerial parts of the seedlings was limited. Overall, K. obovata has the potential to be used as a remediation species in polluted coastal wetlands due to its high phytoextraction capacity and tolerance to As exposure.
