G.P. Bolwell,P. Wojtaszek +1 more
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.About:

Reactive oxygen species and antioxidant machinery in abiotic stress tolerance in crop plants
TL;DR: The biochemistry of ROS and their production sites, and ROS scavenging antioxidant defense machinery are described, which protects plants against oxidative stress damages.
Journal ArticleDOI
Reactive oxygen gene network of plants
TL;DR: In Arabidopsis, a network of at least 152 genes is involved in managing the level of ROS, and this network is highly dynamic and redundant, and encodes ROS-scavenging and ROS-producing proteins.
Journal ArticleDOI
Antioxidants, Oxidative Damage and Oxygen Deprivation Stress: a Review
TL;DR: Factors which possibly affect the effectiveness of antioxidant protection under oxygen deprivation as well as under other environmental stresses are presented.

TL;DR: It is shown here that RHD2 is an NADPH oxidase, a protein that transfers electrons from NADPH to an electron acceptor leading to the formation of reactive oxygen species (ROS) and that ROS accumulate in growing wild-type (WT) root hairs but their levels are markedly decreased in rhd2 mutants.
Journal ArticleDOI
Dual action of the active oxygen species during plant stress responses.
TL;DR: This review discusses the dual action of AOS during plant stress responses, which was first described in pathogenesis but has also recently been demonstrated during several abiotic stress responses.

Journal ArticleDOI
The oxidative burst in plant disease resistance
TL;DR: Emerging data indicate that the oxidative burst reflects activation of a membrane-bound NADPH oxidase closely resembling that operating in activated neutrophils, which underlies the expression of disease-resistance mechanisms.
Journal ArticleDOI
H2O2 from the oxidative burst orchestrates the plant hypersensitive disease resistance response
TL;DR: 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.
Journal ArticleDOI
Resistance gene-dependent plant defense responses.
TL;DR: The essential prerequisites for pathogen recognition and the induction of localized defense responses are examined, showing which responses are required to abolish or retard pathogen growth and how.
Journal ArticleDOI
The Arabidopsis NPR1 gene that controls systemic acquired resistance encodes a novel protein containing ankyrin repeats
TL;DR: Transformation of the cloned wild-type NPR1 gene into npr1 mutants not only restored the responsiveness to SAR induction with respect to PR-gene expression and resistance to infections, but also rendered the transgenic plants more resistant to infection by P. syringae in the absence of SAR induction.

Protection against oxygen radicals: an important defence mechanism studied in transgenic plants
TL;DR: Transgenic plants offered a means by which to achieve a more complete understanding of the roles of the enzymes involved in protection against stress of many types: environmental and man-made.
