The physiological responses to NaCl salinity were investigated in two floating aquatic macrophytes, Pistia stratiotes L. and Salvinia molesta L. With the increasing NaCl concentration a decrease in chlorophyll and carotenoid contents was recorded in Salvinia as compared to Pistia. Also a greater increase in H2O2 accumulation and lipid peroxidation was observed in the shoot and root tissues of Salvinia as compared to Pistia. The superoxide dismutase, glutathione reductase, catalase and guaiacol… 

Some physiological effects of NaCl salinity in Ceratophyllum demersum L., a submerged rootless aquatic macrophyte

TLDR
Observed increases in malondialdehyde contents showed that oxidative damage occurred in membranes resulting from NaCl, and toxicity symptoms probably occurred due to ionic toxicity, imbalance of macro and micronutrients and/or oxidative stress triggered by salinity.

Pysiological effects of NaCl on Ceratophyllum demersum L., a submerged rootless aquatic macrophyte

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated on Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated on Ceratophyllum demersum . Macronutrients N, P and K and micronutrients Zn and Cu were significantly

Salinity and pH effects on floating and emergent macrophytes in a constructed wetland.

TLDR
The aim of this work was to study the tolerance of floating species and T. domingensis exposed to different pH and salinity treatments and demonstrated to be a suitable macrophyte to treat this type of effluents.

Effects of salinity on the physiology of Salvinia auriculata Aubl. (Salviniales, Pteridophyta)

TLDR
Responsibility patterns may help to explain S. auriculata occurrence, and its distribution can be regulated by salinity, which showed reductions under the highest salinity treatment.

Studies on the Effect of Salt Stress in rhizophora apiculata Bl.

TLDR
It was observed that the growth parameters such as root and shoot length, fresh and dry weight increased with increasing concentrations upto 400 mM NaCl, and organic compounds such as aminoacids and total sugar decreased, but protein and starch increased upto the optimal level of 400 mM of NaCl salinity.

Salinity effects on photosynthetic pigments , proline , biomass and nitric oxide in Salvinia auriculata Aubl

Aims: Effects of salt stress on the physiology of Salvinia auriculata were investigated. Method: Plants were supplemented with 0, 50, 100 and 150 mmol L-1 NaCl and incubated for 5 days. NO content

Salt Stress Injury Induces Oxidative Alterations and Antioxidative Defence in the Roots of Lemna minor

Lemna minor L. roots were treated with different concentrations of NaCl. Lipid peroxidation was investigated histochemically and biochemically. At higher NaCl concentrations an increase in staining

Superoxide dismutases: I. Occurrence in higher plants.

TLDR
Nine of the enzyme activities were eliminated with cyanide treatment suggesting that they may be cupro-zinc enzymes, whereas one was cyanide-resistant and may be a manganese enzyme.

Enzymatic and non-enzymatic antioxidant responses of Carrizo citrange, a salt-sensitive citrus rootstock, to different levels of salinity.

TLDR
Data indicate that Carrizo citrange responded to salt-induced oxidative stress by increasing enzymatic and non-enzymatic antioxidant defenses proportionally to the extent of the stress imposed, and that in all plants the malondialdehyde content remained at a moderate level.

The Occurrence of Peroxide in a Perennial Plant, Populus gelrica.

TLDR
A large amount of peroxide was found in twigs of poplar, Populus gelrica, which was grown in the field under natural conditions and served as a substrate both for catalase and cytochrome c peroxidase.

COPPER ENZYMES IN ISOLATED CHLOROPLASTS. POLYPHENOLOXIDASE IN BETA VULGARIS.

TLDR
Evidence that a copper enzyme, polyphenoloxidase (otherwise known as tyrosinase or catecholase), is localized in the chloroplasts of spinach beet (chard), Beta vu?garis is presented.

Evidence for the accumulation of peroxidized lipids in membranes of senescing cotyledons.

TLDR
The observations support the contention that formation of gel phase lipid in senescing membranes is attributable to lipid peroxidation and suggest that the reactions of lipidperoxidation are utilized by the cotyledons to mediate deteriorative changes accompanying the mobilization and transport of metabolites from the storage tissue to the developing embryo.

Antioxidant systems and O(2)(.-)/H(2)O(2) production in the apoplast of pea leaves. Its relation with salt-induced necrotic lesions in minor veins.

TLDR
The results suggest a strong interaction between both cell compartments in the control of the apoplastic ASC content in pea leaves, but this anti-oxidative response does not seem to be sufficient to remove the harmful effects of high salinity.

Reactive oxygen species and antioxidants: Relationships in green cells

TLDR
Current data suggest that complex regulatory mechanisms function at both the gene and protein level to coordinate antioxidant responses and that a critical role is played by organellar localization and inter-compartment coordination.

Light drives photosynthesis, but too much light damages the photosynthetic apparatus (Jones and Kok 1966: Powles 1984). All photosynthetic organisms have developed strategies for avoiding the
