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: Studying the mechanisms through which endophytic fungi protect host plants and their relationship with pathogens is important. This study found that Beauveria bassiana, an endophytic fungus, enhanced the growth of tomatoes infected with the fusarium wilt pathogen. However, it did not improve the antioxidant capacity of the infected plants.

Summary: Beauveria bassiana, known for its role as a biopesticide and endophyte, has been discovered to have the potential for producing an industrially important biocatalyst, xylanase. The purified xylanase from B. bassiana showed specific activity, molecular mass, optimal conditions, and kinetic properties, as well as sensitivity to different metal ions. Additionally, the xylanase demonstrated effective deinking of wastepaper through enzymatic disassociation of fiber-ink bonds, highlighting its biotechnological application.

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: In this study, a simple, green, and environmentally friendly strategy using biochar loaded with self-emulsifying orange peel essential oil (BC/SE-OPEO) was proposed to efficiently adsorb and degrade the aromatic amine p-phenylenediamine (PPD). The results showed that the PPD removal efficiency of 50 mg BC/SE-OPEO reached 98% after 110 min at 40 °C. Mechanistic investigations revealed that reactive oxygen species (ROS) played a vital role in the degradation of PPD, which was eventually degraded to carbon dioxide and water.

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: Free radicals, generated during normal metabolic activities, play a crucial role in neurodegenerative diseases through oxidative stress, which disrupts redox balance. Antioxidant therapy, including nanoparticle-mediated delivery of antioxidant enzymes, shows promise in addressing the challenges of clinical translation in treating these diseases.

Summary: In this study, the natural incidence of entomopathogenic fungi (EF) on stink bug pests in Argentine rice fields was monitored, and the relationship between EF incidence, stink bug feeding guild, and rice cultivar was assessed. The results showed that the occurrence of EF was significantly higher in stem-feeding stink bugs than in seed-feeding stink bugs, and it also differed between different rice varieties. This highlights the potential of using native strains of EF in integrated pest management of stink bugs in rice.

Summary: This study investigates the effect of Beauveria bassiana on the secretion and detection of benzoquinones, specifically in the red flour beetle Tribolium castaneum. The researchers found significant alterations in the secretion and perception of the benzoquinones in the fungus-treated insects. Certain genes involved in odorant-binding and chemosensory processes were also affected. Further research is needed to fully understand the effects of fungal infection on insect chemical ecology.

Summary: Entomopathogenic fungi, such as Beauveria bassiana, produce toxic secondary metabolites that play a role in fungal invasion and immune suppression. The precise function of these metabolites is not well understood but they are typically associated with virulence. This review aims to summarize the available information on the expression of B. bassiana NRPS and PKS genes in different insects during infection, and their role as virulence factors, antimicrobials, or immunosuppressants in the context of fungus-insect interactions.

Summary: In this study, the bioinsecticidal activity and residual effect of a microencapsulation formulation of an entomopathogenic fungus (B. bassiana) were tested against pyrethroid-resistant Triatoma infestans nymphs. The microencapsulated fungus showed higher nymph mortality compared to the non-microencapsulated fungus and maintained conidial viability throughout the evaluation period. Alginate microencapsulation could serve as a cost-effective method for developing a bioinsecticide to reduce Chagas disease transmission.

Summary: This study used dual transcriptomic analysis to investigate the interaction between the entomopathogenic fungus B. bassiana and its host T. castaneum. The results revealed that highly expressed fungal genes were associated with carbon catabolite repression and stress response. Differentially expressed genes related to immune response and chitin modification were found in T. castaneum exposed to the fungus.
