Summary: Aluminum toxicity in acidic soils is a major factor limiting plant growth, but the use of phosphorus can alleviate its toxic effects. This study investigated the effects of phosphorus treatment and aluminum toxicity on the physiological and biochemical behavior of Spinacia oleracea L. It was found that phosphorus application reduced root aluminum content, while increasing leaf aluminum content under aluminum stress. Additionally, aluminum stress altered the activity of certain enzymes, but phosphorus treatment had no effect on SOD activity. Phosphorus treatment also lessened the impact of aluminum stress on MDA and H2O2 content.

Summary: Salinity stress significantly reduces plant height, stem numbers, and tuber yield in potato varieties. Salt-tolerant genotypes exhibit better performance under salt stress due to a strong antioxidant defense system and osmotic adjustment, suggesting their potential for breeding new high-yielding, salt-tolerant lines. Specific physiological and biochemical traits were identified as predominant for tuber yield under salt stress, providing insights for further genetic and molecular studies on salt tolerance in potato.

Summary: Chromium is a highly toxic heavy metal that can negatively affect plants' metabolic processes. Agricultural practices contribute significantly to chromium contamination. Nano-biochar/nBC plays a significant role in mitigating chromium stress in black cumin plants. The foliar application of nBC improved the growth and antioxidant activity of Nigella sativa seedlings under chromium stress. The treatment of 100 mg/L-1 of nBC showed better results compared to 150 mg/L-1.

Summary: This review summarizes the knowledge of heavy metal toxicity, oxidative stress, and antioxidant response in eukaryotic algae. The types of ROS and their damage to cellular components are described, followed by detailed characterization of heavy metals, including their properties, sources of contamination, toxicity mechanisms, and stress symptoms. The review also covers low-molecular-weight antioxidants and ROS-detoxifying enzymes, their properties, cellular localization, and their occurrence in algae belonging to different clades. Additionally, other mechanisms providing tolerance to metal ions are briefly outlined at the end.

Summary: This study investigated the impact of foliar application of microelements on reducing soil copper toxicity in peppermint plants. The results showed that the application of Fe, Zn, and Mn through foliar spray improved plant growth and reduced copper toxicity. Additionally, it increased the activity of ascorbate peroxidase and reduced proline content. This study suggests that foliar application of micronutrients can be a cost-effective and practical approach to mitigate copper contamination in soils.

Summary: Aluminum (Al) toxicity is a major constraint for plant growth and cereal crop yield in acidic soils. This study identified a maize ALDH gene, ZmALDH, which is involved in protection against Al-induced oxidative stress. Overexpression of ZmALDH in Arabidopsis increased Al tolerance by promoting antioxidant mechanisms and reducing Al accumulation in roots.

Summary: This study aims to evaluate the different effects of copper oxide nanoparticles and ionic copper on the digestive glands and gills of mussels. The results show that both copper forms induce oxidative stress. Further research is needed to clarify the genotoxic and neurotoxic effects of copper oxide nanoparticles and ionic copper on freshwater mussels and other biota.

Summary: This study aimed to investigate the transcription of selected antioxidants and relevant genes under varying temperature conditions in Arthrospira platensis. Results showed that the optimal temperature for growth, biochemical constituents, and antioxidants of A. platensis is 30 degrees Celsius, with some antioxidant enzyme activity increasing at lower and higher temperatures. The study highlights the significance of temperature in influencing growth, enzymatic and non-enzymatic antioxidants, and gene expression in A. platensis, providing valuable insights for culturing this organism to harvest specific antioxidants or as an antioxidant-rich food source.

Summary: Algae face challenges of adaptation due to exposure to different stress conditions, such as iron and salinity. Different concentrations of iron and salt have varying effects on algal cell growth. Iron superoxide dismutase (SOD) shows higher activity compared to other SOD isoforms. Antioxidant enzyme activities of catalase (CAT) and peroxidase (POD) are accelerated by increasing iron and salinity stress.
