Tuning of Redox Regulatory Mechanisms, Reactive Oxygen Species and Redox Homeostasis under Salinity Stress
Soil salinity is a crucial environmental constraint which limits biomass production at many sites on a global scale. Saline growth conditions cause osmotic and ionic imbalances, oxidative stress and perturb metabolism, e.g., the photosynthetic electron flow. The plant ability to tolerate salinity is determined by multiple biochemical and physiological mechanisms protecting cell functions, in pa...
متن کاملReactive oxygen species and redox compartmentalization
Reactive oxygen species (ROS) formation and signaling are of major importance and regulate a number of processes in physiological conditions. A disruption in redox status regulation, however, has been associated with numerous pathological conditions. In recent years it has become increasingly clear that oxidative and reductive modifications are confined in a spatio-temporal manner. This makes R...
متن کاملRedox and Reactive Oxygen Species Network in Acclimation for Salinity Tolerance in Sugar Beet
Fine-tuned and coordinated regulation of transport, metabolism and redox homeostasis allows plants to acclimate to osmotic and ionic stress caused by high salinity. Sugar beet is a highly salt tolerant crop plant and is therefore an interesting model to study sodium chloride (NaCl) acclimation in crops. Sugar beet plants were subjected to a final level of 300 mM NaCl for up to 14 d in hydroponi...
متن کامل[Reactive oxygen species signaling and redox homeostasis regulated by 8-nitro-cGMP].
An emerging aspect of redox signaling is the signaling pathway mediated by electrophilic byproducts, such as nitrated cyclic nucleotide (8-nitro-cGMP), generated via reactions of reactive oxygen species (ROS), NO, and their secondary products. We recently clarified that enzymatically-generated hydrosulfide derivatives regulate the metabolism and signaling of 8-nitro-cGMP. Although hydrogen sulf...
متن کاملRedox Mechanism of Reactive Oxygen Species in Exercise
It is well known that regular exercise can benefit health by enhancing antioxidant defenses in the body. However, unaccustomed and/or exhaustive exercise can generate excessive reactive oxygen species (ROS), leading to oxidative stress-related tissue damages and impaired muscle contractility. ROS are produced in both aerobic and anaerobic exercise. Mitochondria, NADPH oxidases and xanthine oxid...
