Journal Article
Cadmium toxicity induced changes in plant water relations and oxidative metabolism of Brassica juncea L. plants.
P K Singh,Rajesh Kumar Tewari +1 more
TL;DR: The deleterious effects of Cd and its effects on oxidative metabolism clearly indicate enhanced generation of reactive oxygen species (ROS) to be instrumental in producing toxic effects ofCd.
Journal ArticleDOI
Photon flux density and light quality induce changes in growth, stomatal development, photosynthesis and transpiration of Withania Somnifera (L.) Dunal. plantlets
TL;DR: Both the quality and the quantity of light affect growth of plantlets, development of stomata and physiological responses differently depending on the intensity and the wavelength of light.
Journal ArticleDOI
Macronutrient deficiencies and differential antioxidant responses—influence on the activity and expression of superoxide dismutase in maize
Rajesh Kumar Tewari,Praveen Kumar,Neeraj Tewari,Sugandha Srivastava,Sugandha Srivastava,Parma Nand Sharma +5 more
TL;DR: Induction of oxidative stress in hydroponically raised maize plants subjected to the deficiency of N, P, K, Ca, Mg or S was investigated by studying the levels of lipid peroxidation, H 2O2, and some important enzymatic antioxidative responses.
Journal ArticleDOI
Magnesium deficiency induced oxidative stress and antioxidant responses in mulberry plants
TL;DR: In this article, the authors implicate induction of oxidative stress and antioxidative responses with the effects of Mg deficiency in mulberry plants, and implicate that Mg-deficiency decreased concentrations of photosynthetic pigments, and increased concentrations of H2O2 and ascorbate and activities of antioxidative enzymes.
Journal ArticleDOI
Modulation of oxidative stress responsive enzymes by excess cobalt
TL;DR: Increase in dry matter yield of plants supplied 50 μM cobalt and the decrease in lipid peroxidation with increasing cobalt supply in the range 50–200 μM is suggested as a result from depletion of functional iron as phosphate and/or in ferritin.
