Rapid generation of superoxide and accumulation of H2O2 is a characteristic early feature of the hypersensitive response following perception of pathogen avirulence signals. Emerging data indicate that the oxidative burst reflects activation of a membrane-bound NADPH oxidase closely resembling that operating in activated neutrophils. The oxidants are not only direct protective agents, but H2O2 also functions as a substrate for oxidative cross-linking in the cell wall, as a threshold trigger for… Expand
Nitric oxide functions as a signal in plant disease resistance
TLDR
It is shown that nitric oxide potentiates the induction of hypersensitive cell death in soybean cells by reactive oxygen intermediates and functions independently of such intermediates to induce genes for the synthesis of protective natural products. Expand
Reactive Oxygen Intermediates Mediate a Systemic Signal Network in the Establishment of Plant Immunity
TLDR
It is shown that inoculation of Arabidopsis leaves with avirulent Pseudomonas syringae induces secondary oxidative bursts in discrete cells in distant tissues, leading to low-frequency systemic micro-HRs. Expand
Mechanisms for the generation of reactive oxygen species in plant defence response
TLDR
Two major models depicting the origin of ROS in the oxidative burst are described and the participation of exocellular ROS-generating enzymes, like germin-like oxalate oxidases and amine oxidases, in plant defence response is demonstrated. Expand
REACTIVE OXYGEN SPECIES AND THEIR ROLE IN PLANT DEFENSE AGAINST PATHOGEN INGRESS
TLDR
The Oxidative burst at the plant cell surface drives rapid peroxidase-mediated oxidative cross-linking of structural proteins in the cell wall, thereby reinforcing this physical barrier against pathogen ingress. Expand
Functions of the respiratory burst oxidase in biotic interactions, abiotic stress and development.
TLDR
Emerging evidence suggests a broader role for ROI as signals that mediate responses to infection, the abiotic environment, developmental cues, and programmed cell death in different cell types. Expand
Quantitative Detection of Oxidative Burst upon Activation of Plant Receptor Kinases.
TLDR
The detection of extracellularly produced ROS in plant leaf pieces using a chemiluminescence-based bioassay with the luminol L-012 as a substrate being oxidized in the presence of ROS is outlined. Expand
The apoplastic oxidative burst in response to biotic stress in plants: a three-component system.
TLDR
The oxidative burst, the generation of reactive oxygen species (ROS) in response to microbial pathogen attack, is a ubiquitous early part of the resistance mechanisms of plant cells and the mechanism has proved to be complex and may involve a number of low molecular weight components. Expand
Nitric oxide signalling in the plant hypersensitive disease resistance response
TLDR
Nitric oxide, a well known host-defense component in animal systems, co-operates with reactive oxygen intermediates in the induction of hypersensitive cell death, and functions independently of such intermediate in the induction of defense related genes. Expand
Mechanisms for the generation of reactive oxygen species in plant defence – a broad perspective
TLDR
Two major models describing the origin of ROS in the oxidative burst are presented, namely: the NADPH oxidase system analogous to that of mammalian phagocytotic cells, and the pH-dependent generation of hydrogen peroxide by exocellular peroxidases. Expand
Hydrogen peroxide functions as a stress signal in plants
TLDR
The function of H2O2 as a signal molecule in the transduction of stress signals to the alteration of expression profiles of target genes is reviewed, and the evidence that H 2O2 acts as a stress signal in plants is summarized. Expand

Function of the oxidative burst in hypersensitive disease resistance.
TLDR
These findings provide the basis for an integrated model for the orchestration of the localized hypersensitive resistance response to attack by an avirulent pathogen. Expand

TLDR
Importantly, phosphatase inhibitors were found to induce the oxidative burst in the absence of any additional stimulus, which may suggest that certain kinases required for the burst are constitutively active and that stabilization of the phosphorylated forms of their substrates is all that is required for burst activity. Expand
H2O2 from the oxidative burst orchestrates the plant hypersensitive disease resistance response
TLDR
It is reported here that H2O2 from this oxidative burst not only drives the cross-linking of cell wall structural proteins, but also functions as a local trigger of programmed death in challenged cells and as a diffusible signal for the induction in adjacent cells of genes encoding cellular protectants. Expand
Calcium-mediated apoptosis in a plant hypersensitive disease resistance response
TLDR
O2 stimulates a rapid influx of Ca2+ into soybean cells, which activates a physiological cell death program resulting in the generation of large DNA fragments and cell corpse morphology--including cell shrinkage, plasma membrane blebbing and nuclear condensation--characteristic of apoptosis. Expand
Rapid Stimulation of an Oxidative Burst during Elicitation of Cultured Plant Cells : Role in Defense and Signal Transduction.
TLDR
The results suggest that H(2)O(2), implicated as a second messenger of hormone-stimulated metabolic changes in some animal cells, also plays an important role in inducing subsequent defense responses such as phytoalexin production. Expand
Programmed cell death in plants: A pathogen-triggered response activated coordinately with multiple defense functions
In plants, the hypersensitive response (HR) to pathogens involves rapid cell death, which is hypothesized to arise from the activation of a cell death program. We describe mutant A. thaliana plantsExpand
Initiation of Runaway Cell Death in an Arabidopsis Mutant by Extracellular Superoxide
TLDR
Runaway cell death seen in lsd1 plants reflected abnormal accumulation of superoxide and lack of responsiveness to signals derived from it. Expand
The origin of the oxidative burst in plants.
TLDR
An alternative simple and rapid mechanism thus exists for the generation of H2O2 which does not require such multiple proteinaceous components. Expand
Involvement of the oxidative burst in phytoalexin accumulation and the hypersensitive reaction.
TLDR
It is suggested that an oxidative burst consisting of H( 2)O(2) and O(2%) (-) does occur during these two plant defense responses, but it may not be a necessary element of the signaling system for HR and phytoalexin formation. Expand
Salicylic acid potentiates an agonist-dependent gain control that amplifies pathogen signals in the activation of defense mechanisms.
The phenylpropanoid-derived natural product salicylic acid (SA) plays a key role in disease resistance. However, SA administered in the absence of a pathogen is a paradoxically weak inductive signal,Expand
