Several reactive oxygen species (ROS) are continuously produced in plants as byproducts of aerobic metabolism. Depending on the nature of the ROS species, some are highly toxic and rapidly detoxified by various cellular enzymatic and nonenzymatic mechanisms. Whereas plants are surfeited with mechanisms to combat increased ROS levels during abiotic stress conditions, in other circumstances plants appear to purposefully generate ROS as signaling molecules to control various processes including…

Reactive oxygen species, antioxidants and signaling in plants

Special attention is given to ROS and ROS-anioxidant interaction as a metabolic interface for different types of signals derived from metabolisms and from the changing environment.

Reactive oxygen species in plants: their generation, signal transduction, and scavenging mechanisms

The generation, origin, and role of ROS in signal transduction and cell death, and the removal of ROS by antioxidative defense systems in plants during various developmental pathways are described.

Signaling Toward Reactive Oxygen Species-Scavenging Enzymes in Plants

This review aimed to summarize the current knowledge on signaling processes regulating the enzymatic antioxidant capacity of plants, which represents a major ROS-scavenging force and are crucial for stress tolerance in plants.

Although the mechanisms that control ROS signaling remain to be established more precisely, it is beginning to understand how ROS signals are integrated to finally regulate biological processes such as development, acclimation, hypersensitive reactions and programmed cell death.

Experimental systems to assess the effects of reactive oxygen species in plant tissues

The major challenge is the identification of ROS sensors and signaling components to finally elucidate the molecular mechanisms of oxidative stress response in plants.

Reactive oxygen species: Generation, Oxidative Damage, and Signal Transduction

The Variety of Reactive oxygen species, sources and roles of ROS in plants is described, including conferment of tolerance to various environmental stresses.

Reactive Oxygen Species Signaling in Plants

Various roles of ROS and enzymes in plant responses to stress regulation and metabolism are discussed, and they can cause oxidative damage to indigenous enzymes, proteins, and nucleic acids.

Reactive Oxygen Species in Plants: From Source to Sink

The current review provides an in-depth look at the fate of ROS in plants, a beneficial role in managing stress and other irregularities, and the biochemical properties and sources of ROS generation, capture systems and the influence of ROS on cell biochemistry are discussed.

Reactive oxygen signaling and abiotic stress.

Using mutants deficient in key ROS-scavenging enzymes, a signaling pathway is defined that is activated in cells in response to ROS accumulation and how ROS integrate different signals originating from different cellular compartments during abiotic stress is discussed.



Reactive oxygen species and antioxidants: Relationships in green cells

Current data suggest that complex regulatory mechanisms function at both the gene and protein level to coordinate antioxidant responses and that a critical role is played by organellar localization and inter-compartment coordination.

Regulation of gene expression by reactive oxygen.

This review examines the sources and generation of free radicals and oxidative stress in biological systems and the mechanisms used by reactive oxygen to modulate signal transduction cascades and redirect gene expression.

Active oxygen in plant pathogenesis.

Modifications of the luminol-dependent chemiluminescence assay have facilitated studies on both the production and scavenging of active oxygen that occurs during incompatible plantlbacteria interactions, and it is still unclear which mechanisms predominate during plant! pathogen interactions.

The oxidative burst in plant defense: Function and signal transduction

A hypothetical model is constructed that proposes how different elicitors might induce the oxidative burst in the same cell by different pathways, and strong evidence is found for participation of phospholipases, H+/K+ exchange, Ca2+ influxes, protein kinases and phosphatases, and GTP binding proteins.

The hypothesis that suppression of ROI-scavenging enzymes during the hypersensitive response plays an important role in enhancing pathogen-induced PCD is supported.

Regulation of the Arabidopsis transcriptome by oxidative stress.

A large-scale analysis of the Arabidopsis transcriptome during oxidative stress identified 175 non-redundant expressed sequence tags that are regulated by H(2)O(2), and a substantial proportion have predicted functions in cell rescue and defense processes.

Two Distinct Sources of Elicited Reactive Oxygen Species in Tobacco Epidermal Cells.

The physiological relevance of ROS-generated signals was indicated by the rapid alteration of the epidermal cell glutathione pool and the cellular redox state, and induction of ROS by all elicitors was correlated with subsequent cell death.

Signal interactions between nitric oxide and reactive oxygen intermediates in the plant hypersensitive disease resistance response

It is shown that in soybean cells unregulated NO production at the onset of a pathogen-induced hypersensitive response (HR) is not sufficient to activate hypersensitive cell death, and the HR is triggered only by balanced production of NO and ROIs.
