Antioxidant defense mechanism in hydroponically grown Zea mays seedlings under moderate lead stress.
Zea mays can be used as an indicator species for Pb, and the various antioxidants might play a key role in the detoxification of Pb induced toxic effects.
Cadmium toxicity causes oxidative stress and induces response of the antioxidant system in cucumber seedlings
The results evidence the importance of the enzymatic and non-enzymatic antioxidant system in response to cadmium toxicity in cucumber seedlings.
Aluminum-induced oxidative stress in cucumber.
The antioxidant system was unable to overcome toxicity resulting in negative effects such as lipid peroxidation, protein oxidation and a decrease in the growth of Cucumis seedlings.
Effect of Hg, As and Pb on biomass production, photosynthetic rate, nutrients uptake and phytochelatin induction in Pfaffia glomerata
P. glomerata plantlets could not cooperatively induce phytochelatins under any of Hg and Pb levels and the level of photosynthetic pigments alters significantly in response to all metal/metalloid treatment.
Mercury toxicity induces oxidative stress in growing cucumber seedlings.
It is suggested that Hg induces oxidative stress in cucumber, resulting in plant injury, and isomersally significant in roots and shoot length.
Behavior and brain enzymatic changes after long-term intoxication with cadmium salt or contaminated potatoes.
An association between the long-term diet of potato tuber and a clear anxiolytic effect is suggested between Cd-intoxicated rats and a marked increase of brain Cd concentration, and increase and decrease of AChE and Na+,K+-ATPase activities, respectively.
Physiological and oxidative stress responses of four potato clones to aluminum in nutrient solution
Results indicate that oxidative stress caused by Al in potato may harm several components of the cell, mainly in Al-sensitive clones.
Cadmium and mineral nutrient accumulation in potato plantlets grown under cadmium stress in two different experimental culture conditions.
The data suggest that the influence of Cd(2+) on nutrient content in potato was related to the level of Ccd( 2+) in the substrate, potato cultivar, plant organ, essential element, growth medium and exposure time.
Effect of aluminum on δ-aminolevulinic acid dehydratase (ALA-D) and the development of cucumber (Cucumis sativus)
Analysis of the activity of the enzyme δ-aminolevulinic acid dehydratase, responsible for the formation of the monopyrrole porphobilinogen that is part of the chlorophyll molecule, as well as the cytochromes, in cucumbers demonstrated that aluminum inhibits this enzyme and also greatly impairs plant growth.
Tolerance and translocation of heavy metals in young grapevine (Vitis vinifera) grown in sandy acidic soil with interaction of high doses of copper and zinc
Abstract Vineyard soils may have high levels of copper due to frequent applications of Bordeaux mixture for the control of fungal diseases. Therefore, many winegrowers have used zinc-based fungicides
