Localization of S-nitrosoglutathione and expression of S-nitrosoglutathione reductase in pea plants under cadmium stress.
TLDR
Results indicate that GSNO is associated with a specific plant cell type, and this metabolite and its related catabolic activity, GSNOR, are both down-regulated under Cd stress. Expand
Localization of Nitric-oxide Synthase in Plant Peroxisomes*
TLDR
The presence of NOS in peroxisomes suggests that these oxidative organelles are a cellular source of nitric oxide (NO) and implies new roles for peroxISomes in the cellular signal transduction mechanisms. Expand
Nitrosative stress in plants
TLDR
It is shown that in olive leaves salinity induces nitrosative stress, and vascular tissues could play an important role in the redistribution of NO‐derived molecules during nitrosatives stress. Expand
Metabolism of reactive nitrogen species in pea plants under abiotic stress conditions.
TLDR
The results obtained suggest that low and high temperature, continuous light and high light intensity are abiotic stress conditions that can induce nitrosative stress in pea plants. Expand
The dehydrogenase-mediated recycling of NADPH is a key antioxidant system against salt-induced oxidative stress in olive plants.
TLDR
Results indicate that in olive plants, salinity causes reactive oxygen species (ROS)-mediated oxidative stress, and plants respond to this situation by inducing different antioxidative enzymes, especially the NADPH-producing dehydrogenases in order to recycle NADPH necessary for the protection against oxidative damages.

Cellular and Subcellular Localization of Endogenous Nitric Oxide in Young and Senescent Pea Plants12
TLDR
The cellular and subcellular localization of endogenous nitric oxide (NO˙) in leaves from young and senescent pea plants was studied and it is proposed that peroxisomal NO˙ could be involved in the process of senescence of pea leaves. Expand
Constitutive arginine-dependent nitric oxide synthase activity in different organs of pea seedlings during plant development
TLDR
These loci of NO generation and accumulation suggest novel functions for NO in these cell types, and the arginine-dependent NOS activity was constitutive and sensitive to aminoguanidine, a well-known irreversible inhibitor of animal NOS, and this NOSActivity was differentially modulated depending on the plant organ and seedling developmental stage. Expand
Mechanical wounding induces a nitrosative stress by down-regulation of GSNO reductase and an increase in S-nitrosothiols in sunflower (Helianthus annuus) seedlings
TLDR
It is proposed that mechanical wounding triggers the accumulation of SNOs, specifically GSNO, due to a down-regulation of GSNOR activity, while NO2-Tyr increases, and a process of nitrosative stress is induced in sunflower seedlings and SNOs constitute a new wound signal in plants. Expand
Involvement of reactive nitrogen and oxygen species (RNS and ROS) in sunflower-mildew interaction.
TLDR
The results suggest that pathogens induce nitrosative stress in susceptible cultivars and the increase of tyrosine nitration of proteins can be considered a general biological marker of nitrosive stress in plants under biotic conditions. Expand
Metabolism of reactive oxygen species and reactive nitrogen species in pepper (Capsicum annuum L.) plants under low temperature stress.
TLDR
Pepper plants underwent cold acclimation by adjusting their antioxidant metabolism and reverting the observed nitrosative and oxidative stress, suggesting that ascorbate, glutathione and the NADPH-generating dehydrogenases have a role in the process of cold Acclimation through their effect on the redox state of the cell.
