Thylakoid Rhodanese-like Protein–Ferredoxin:NADP⁺ Oxidoreductase Interaction Is Integrated into Plant Redox Homeostasis System

Antioxidants, 2023
In vascular plants, the final photosynthetic electron transfer from ferredoxin (Fd) to NADP+ is catalyzed by the flavoenzyme ferredoxin:NADP+ oxidoreductase (FNR).

Mitochondrial ROS and the effectors of the intrinsic apoptotic pathway in aging cells: the discerning killers!

Frontiers in Genetics, 2016
It has become clear that mitochondrial reactive oxygen species (mtROS) are not simply villains and mitochondria the hapless targets of their attacks. Rather, it appears that mitochondrial dysfunction itself and the signaling function of mtROS can have ...

Species-level variability in extracellular production rates of reactive oxygen species by diatoms

Frontiers in Chemistry, 2016
Biological production and decay of the reactive oxygen species (ROS) hydrogen peroxide (H2O2) and superoxide (O2-) likely have significant effects on the cycling of trace metals and carbon in marine systems. In this study, extracellular production rates
