Spatial dependence for hydrogen peroxide-directed signaling in light-stressed plants.
In this article, the role of the reactive oxygen species (ROS) hydrogen peroxide (H2O2) as a signaling molecule involved in plant response to a sudden change in light intensity will be considered in a spatial context. The relatively low reactivity of H2O2 compared with other ROS (Halliwell and Gutteridge, 1985) might suggest that it could diffuse from a site of production to initiate intracellu...
متن کاملPeroxisomes as a source of superoxide and hydrogen peroxide in stressed plants.
Superoxide dismutases (SODs) and superoxide radicals in peroxisomes Peroxisomes are subcellular respiratory organelles that contain catalase and H202-producing flavin oxidases as basic enzymatic constituents [1,2]. In recent years, it has become increasingly clear that peroxisomes carry out essential functions in almost all eukaryotic cells [3-51, and an important characteristic of peroxisomes ...
متن کاملHydrogen peroxide sensing and signaling.
It is well established that oxidative stress is an important cause of cell damage associated with the initiation and progression of many diseases. Consequently, all air-living organisms contain antioxidant enzymes that limit oxidative stress by detoxifying reactive oxygen species, including hydrogen peroxide. However, in eukaryotes, hydrogen peroxide also has important roles as a signaling mole...
متن کاملHydrogen peroxide: a signaling messenger.
Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays important roles in host defense and oxidative biosynthetic reactions. In addition there is growing evidence that at low levels, H2O2 also functions as a signaling agent, particularly in higher organisms. This review evaluates the evidence that H2O2 functions as a signaling agent in higher organisms in light of the...
متن کاملHydrogen peroxide signaling in vascular endothelial cells
Redox signaling is implicated in different physiological and pathological events in the vasculature. Among the different reactive oxygen species, hydrogen peroxide (H2O2) is a very good candidate to perform functions as an intracellular messenger in the regulation of several biological events. In this review, we summarize the main physiological sources of H2O2 in the endothelium and the molecul...
