WebNov 1, 2016 · Reactive oxygen species (ROS) play a key role in the acclimation process of plants to abiotic stress. They primarily function as signal transduction molecules that regulate different pathways during plant acclimation to stress, but are also toxic byproducts of stress metabolism. WebMay 20, 2024 · Due to the strong oxidation potential, the excess ROS induced by nanoparticles can result in the damage of biomolecules and organelle structures and lead to protein oxidative carbonylation, lipid peroxidation, DNA/RNA breakage, and membrane structure destruction, which further cause necrosis, apoptosis, or even mutagenesis.

WebReactive oxygen species cause oxidative damage to several bacterial targets, including DNA (Imlay et al., 1988). As purine auxotrophs lack the ability to synthesize purine nucleotides and hence DNA and RNA, we hypothesized that the intramacrophage attenuation of purine auxotrophs might be due to their inability to repair DNA damage … WebApr 13, 2024 · The NLRP3 inflammasome and autophagy activation via hypoxic inducible factor 1 alpha (HIF-1α) and mitochondrial reactive oxygen species (ROS) production was also confirmed.
