In this mini-review, an updated and comprehensive overview is presented of the evidence available demonstrating that plant peroxisomes have the capacity to generate NO, and how this molecule and its derived products, peroxynitrite (ONOO −) and S-nitrosoglutathione (GSNO), can modulate the ROS metabolism of peroxisomes, mainly throughout ...

Feb 10, 2019 · Nitric oxide (NO) is a gaseous free radical endogenously generated in plant cells. Peroxisomes are cell organelles characterized by an active metabolism of reactive oxygen species (ROS) and are also one of the main cellular sites of NO production in higher plants.

In this review, we discuss the chemistry of NO and ROS in the context of antipathogen activity and immune regulation and also discuss similarities and differences between murine and human production of these intermediates.

As universal toxic chemicals in plant and animal cells, reactive oxygen or nitrogen species (ROS or RNS), mainly superoxide anion (O 2−•), hydrogen peroxide (H 2 O 2) or nitric oxide (• NO), have been studied extensively for their roles in PCD induction. Physiological and genetic studies have convincingly shown their essential roles.

May 1, 2010 · The production of ROS and NO is an integral part of the response to oxygen deprivation which encompasses several levels of metabolic regulation to sustain redox signaling and to prevent oxidative damage.

Dec 1, 2024 · Our analysis demonstrates that NPs exert multifaceted effects on ROS and • NO dynamics, and can act both as inducers and regulators of cellular redox processes. Simultaneously, ROS and • NO reciprocally influence NP behavior, with implications for particle uptake, translocation, and toxicity in plants. This multifunctional bidirectional ...

NO and ROS are two central messenger molecules which act differentially to upregulate or downregulate the expression of genes pertaining to auxin synthesis and to the configuration of root architecture.

Reactive oxygen species (ROS) and nitric oxide (NO) are produced in all aerobic life forms under both physiological and adverse conditions. Unregulated ROS/NO generation causes nitro-oxidative damage, which has a detrimental impact on the function of essential macromolecules.

Dec 12, 2019 · Reactive oxygen species (ROS) and nitric oxide (NO) are produced in all aerobic life forms under both physiological and adverse conditions. Unregulated ROS/NO generation causes nitro-oxidative damage, which has a detrimental impact on the function of essential macromolecules.

Nov 16, 2016 · The Research Topic on the Interplay between NO signaling, ROS and the antioxidant system in plants aims to provide an up-to-date view of this increasingly important area through both original articles and detailed reviews. NO and ROS signaling pathways are key regulators of plant development.
