Reactive oxygen species, antioxidant systems and nitric oxide in peroxisomes.
Peroxisomes are subcellular organelles with an essentially oxidative type of metabolism. Like chloroplasts and mitochondria, plant peroxisomes also produce superoxide radicals (O2*(-)) and there are,Expand

Peroxisomes as a source of reactive oxygen species and nitric oxide signal molecules in plant cells.
The important role of plant peroxisomes in a variety of metabolic reactions such as photorespiration, fatty acid beta-oxidation, the glyoxylate cycle and generation-degradation of hydrogen peroxideExpand

Nitrosative stress in plants
Nitrosative stress has become a usual term in the physiology of nitric oxide in mammalian systems. However, in plants there is much less information on this type of stress. Using olive leaves asExpand

Localization of Nitric-oxide Synthase in Plant Peroxisomes*
The presence of nitric-oxide synthase (NOS) in peroxisomes from leaves of pea plants (Pisum sativum L.) was studied. Plant organelles were purified by differential and sucrose density gradientExpand

Localization of S-nitrosoglutathione and expression of S-nitrosoglutathione reductase in pea plants under cadmium stress.
S-nitrosoglutathione (GSNO) is considered a natural nitric oxide (NO.) reservoir and a reactive nitrogen intermediate in animal cells, but little is known about this molecule and its metabolism inExpand

Metabolism of reactive nitrogen species in pea plants under abiotic stress conditions.
Nitric oxide (*NO) is a key signaling molecule in different physiological processes of animals and plants. However, little is known about the metabolism of endogenous *NO and other reactive nitrogenExpand

The dehydrogenase-mediated recycling of NADPH is a key antioxidant system against salt-induced oxidative stress in olive plants.
NADPH is an important molecule in the redox balance of the cell. In this paper, using olive tissue cultures as a model of the function of the NADPH-generating dehydrogenases in the mechanism ofExpand

Cellular and Subcellular Localization of Endogenous Nitric Oxide in Young and Senescent Pea Plants12
The cellular and subcellular localization of endogenous nitric oxide (NO˙) in leaves from young and senescent pea (Pisum sativum) plants was studied. Confocal laser scanning microscopy analysis ofExpand

Peroxisomes Are Required for in Vivo Nitric Oxide Accumulation in the Cytosol following Salinity Stress of Arabidopsis Plants1[C][W][OA]
Peroxisomes are unique organelles involved in multiple cellular metabolic pathways. Nitric oxide (NO) is a free radical active in many physiological functions under normal and stress conditions.Expand
