Ingia / Ingia

Zinc is one of the eight trace elements which are essential for the normal healthy growth and reproduction of crop plants. Plants possess cellular mechanisms that may be involved in the detoxification of heavy metals and thus confer plants a better tolerance against them. Arbuscular mycorrhizal

Carboxylated multi-walled carbon nanotubes exacerbated oxidative damage in roots of Vicia faba L. seedlings under combined stress of lead and cadmium.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Multi-walled carbon nanotubes (MWCNTs) and heavy metals could be absorbed and bioaccumulated by agricultural crops, implicating ecological risks. Herein, the present study investigated the ecotoxicological effects and mechanisms of individual carboxylated MWCNTs (MWCNTs-COOH) (2.5, 5.0 and 10 mg/L)

Effects of exposure to nano and bulk sized TiO2 and CuO in Lemna minor.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Nanoparticles of TiO2 and CuO are among most commonly used nanoparticles, and elevated concentrations of them are expected to be found in all environments, including aquatic. A standard growth inhibition test ISO/CD 20079 was used to determine the toxicity of nano sized and larger micro sized (bulk)

Effect of cadmium toxicity on the level of lipid peroxidation and antioxidative enzymes activity in wheat plants colonized by arbuscular mycorrhizal fungi.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

High concentrations of heavy metals in the soil have an adverse effect on micro-organisms and microbial processes. Mycorrhizas are among the extracellular strategies to avoid metal toxicity. In the present study, the effect of cadmium on lipid peroxidation and antioxidative enzymes activity of AM

Copper toxicity in expanding leaves of Phaseolus vulgaris L.: antioxidant enzyme response and nutrient element uptake.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Bioaccumulation and toxicity of copper (CuSO4) were assessed in expanding leaves of 14-day-old bean seedlings. CuSO4 was administrated in the growth medium for three days and changes in the activities of the antioxidant enzymes guaiacol peroxidase (GPX) and catalase (CAT), and in the H2O2 production

Effect of cadmium stress on inductive enzymatic and nonenzymatic responses of ROS and sugar metabolism in multiple shoot cultures of Ashwagandha (Withania somnifera Dunal).

Ingia / Ingia

Withania somnifera is one of the most important medicinal plant and is credited with various pharmacological activities. In this study, in vitro multiple shoot cultures were exposed to different concentrations (5-300 μM) of cadmium (Cd) as cadmium sulphate to explore its ability to accumulate the

Differential response of antioxidant enzymes in leaves of necrotic wheat hybrids and their parents.

Ingia / Ingia

The leaves of necrotic hybrid of wheat (Triticum aestivum L.) exhibited high superoxide content associated with increased lipid peroxidation and membrane damage in earlier studies (Khanna-Chopra et al. 1998, Biochem Biophys Res Commun 248: 712-715; Dalal and Khanna-Chopra 1999, Biochem Biophys Res

Ingia / Ingia

BACKGROUND Some radiation-mutagenised chickpea mutants potentially resistant to the broomrape, Orobanche foetida Poir., were selected through field trials. The objectives of this work were to confirm resistance under artificial infestation, in pots and mini-rhizotron systems, and to determine the

Up-regulation of antioxidants in tobacco by low concentrations of H₂O₂ suppresses necrotic disease symptoms.

Ingia / Ingia

Pretreatment of tobacco leaves with low concentrations (5 to 10 mM) of H₂O₂ suppressed hypersensitive-type necrosis associated with resistance to Tobacco mosaic virus (TMV) or Pseudomonas syringae pv. phaseolicola. The same pretreatment resulted in suppression of normosensitive necrosis associated
