We examined the effects of antioxidants and the role of reactive oxygen species (ROS) on the antibacterial action of aminoglycosides in Escherichia coli. We concluded that reduced streptomycin sensitivity in the presence of glutathione and ascorbic acid is not due to the antioxidant-mediated scavenging of ROS.

Background: Phaseolus vulgaris is a warm-season crop sensitive to low temperatures, which can adversely affect its growth, yield, and market value. Exogenous growth regulators, such as diethyl aminoethyl hexanoate (DA-6), have shown potential in alleviating stress caused by adverse environmental conditions. However, the effects that DA-6 has on P.

In the background of antioxidation properties of selenium (Se) in plants, the role of nano‑selenium (Se-NPs) was justified in the modulation of Capsicum fruit ripening. In our study, exogenous application of 8 mg L Se-NPs on fruits through 7 days (D) of postharvest storage regulated decay rate, water loss and fruit coat firmness. Se-NPs recovered fruit coat damages with reduction of ion leakage, lipid oxidation, and accumulation of polyamines.

Heavy metal pollution, especially arsenic toxicity, significantly impairs plant growth and development. Phenolic acids, known for their antioxidant properties and involvement in stress signaling, are gaining increased attention as plant secondary metabolites with the potential to enhance plant resistance to these stressors. This study aimed to investigate the effects of different concentrations of syringic acid (SA1, 10 μM; SA2, 250 μM; SA3, 500 μM) on growth, photosynthetic parameters, and antioxidant activity in lettuce seedlings subjected to arsenic stress (As, 100 μM).
