Update on Reactive Oxygen Species in Plant Pathology Reactive Oxygen Species Signaling in Response to Pathogens
The production of reactive oxygen species (ROS), via consumption of oxygen in a so-called oxidative burst, is one of the earliest cellular responses following successful pathogen recognition. Apoplastic generation of superoxide (O2 ), or its dismutation product hydrogen peroxide (H2O2), has been documented following recognition of a variety of pathogens (Doke, 1983; Auh and Murphy, 1995; Grant ...
متن کاملUpdate on Reactive Oxygen Species in Plant Cell Death Reactive Oxygen Species in Plant Cell Death
Paradoxically, death is an integral part of life. Cell death is essential for growth and development of eukaryotes, by maintaining tissue and organ homeostasis in concert with cell proliferation, growth, and differentiation. Until recently, the wide variety of cell death types reported in the literature was mostly caged in two semantic categories: apoptosis and necrosis. Discrimination between ...
متن کاملO 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
متن کاملUpdate on Reactive Oxygen Species in Chloroplasts Production and Scavenging of Reactive Oxygen Species in Chloroplasts and Their Functions
The reaction centers of PSI and PSII in chloroplast thylakoids are the major generation site of reactive oxygen species (ROS). Photoreduction of oxygen to hydrogen peroxide (H2O2) in PSI was discovered over 50 years ago by Mehler (1951). Subsequently, the primary reduced product was identified to be superoxide anion (O2 ), and its disproportionation produces H2O2 and O2 (Asada et al., 1974). On...
متن کاملUpdate on Reactive Oxygen Species Signaling Mitogen-Activated Protein Kinases and Reactive Oxygen Species Signaling in Plants
In plants, reactive oxygen species (ROS) can be generated by various processes occurring in different cellular compartments. Under physiological steady-state conditions, ROS are scavenged by different antioxidative components, but the balance between production and scavenging of ROSmay be perturbed by a number of adverse environmental factors, giving rise to rapid increases in intracellular ROS...
