Summary: Constitutive pigmentation determines the response to sun exposure and the risk for melanoma. The levels of eumelanin and pheomelanin in melanocytes are inversely correlated with reactive oxygen species (ROS) levels and directly correlated with antioxidant enzyme levels. Solar UV increases antioxidant enzyme levels and induces p53 and lipid peroxidation in melanocytes, which are inversely correlated with melanin levels.

Summary: This study investigated the effects of post-harvest chitosan treatment on ROS production, cell membrane integrity, and antioxidant systems in wounded apples during storage. The results showed that chitosan treatment stimulated antioxidant enzyme activities and reduced lipid peroxidation and membrane permeability in the wounded fruits. Additionally, chitosan increased the activities and substrates of the ascorbate-glutathione cycle-related enzymes. These findings suggest that chitosan can scavenge ROS and maintain fruit membrane integrity, making it a favorable preservative for inducing stress tolerance and preserving fruit quality.

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: The field of oxygen free radicals, antioxidants, and reactive oxygen species (ROS) has seen significant growth, with ROS playing important roles in living organisms. However, many studies lack mechanistic meaning. Detailed understanding of the molecular mechanisms of ROS and appropriate measurement methods for both ROS and oxidative damage are necessary for progress.

Summary: Drought is a major threat to sustainable agricultural productivity, and finding a long-term solution to increase plants' tolerance to drought stress has been a key research focus. The present study provides persuasive evidence on the potential roles of zinc supplements in promoting tolerance of cotton plants exposed to drought. The results suggest that soil supplementation of zinc sulfate or zinc oxide improves various physiological, morphological, and biochemical features of cotton plants under drought stress, indicating their potential as effective techniques for boosting plant resilience to drought.

Summary: Maize is globally the most important cereal crop, but it has been facing various challenges from environmental factors, including salt stress caused by climate change. This review provides an overview of the intricate relationships between salt stress and several plant defense mechanisms in maize, such as osmolytes, antioxidant enzymes, reactive oxygen species, plant hormones, and ions (Na+, K+, Cl-), which are critical for salt tolerance. It addresses the regulatory strategies and key factors involved in salt tolerance, aiming to enhance the understanding of the salt tolerance regulatory networks in maize.

Summary: Plastic contamination is a pressing environmental issue due to the increasing production of disposable plastic products. In this study, onion roots were exposed to commercial polystyrene (PS-MPs) and polymethyl methacrylate microparticles (PMMA-MPs) to investigate their effects. The results showed that PS-MPs were more readily taken up by onion roots compared to PMMA-MPs. Both types of microparticles did not induce toxic effects on root growth, and PMMA-MPs even stimulated root growth. Antioxidant enzymes were activated in root cells after exposure to both types of microparticles.

Summary: In this study, it was demonstrated that B. oleracea extract has inhibitory effects on the germination and growth of P. miliaceum. The extract altered the activities of oxidative enzymes and increased the content of phytohormones in P. miliaceum seedlings. The presence of auxins and their analogs in the extract may contribute to the suppression of P. miliaceum growth.

Summary: Temperature rise has a negative impact on soybean productivity, and there are differences in soybean genotypes' response to high temperatures. An increase in temperature leads to a decline in leaf area, total biomass, photosynthesis, pollen germination, and reproductive efficiency, and a significant decrease in seed yield. However, heat tolerance can be improved through plant breeding programs.
