Plantago major Protective Effects on Antioxidant Status after Administration of 7,12-DMBA in Rats
Polycyclic aromatic hydrocarbons (PAH) are organic pollutants that are released into the environment in large quantities, mainly due to human activities (Neef, 1985). 7,12Dimethylbenz(a)anthracene (DMBA) is one of polycyclic aromatic hydrocarbons chemical group. DMBA is known as carcinogenic (Hsue et al., 2008), mutagenic (Donovan et al., 2004), cytotoxic (Burchiel et al., 1992) and immunosuppr...
متن کاملThe Effect of Zinc excess on antioxidant enzymes, proline and soluble carbohydrates in Plantago major L.
The increase of environmental pollutants especially heavy metals derives from human industrial communities. Zinc is one of the natural elements that exist in biotic environment, plants body, and animals in different forms. Zinc has toxic and lethal effects in high concentrations on plants. Also some plants are introduced as accumulators of this element. Therefore, an investigation was carried o...
متن کاملEffects of ozone on the production and utilization of assimilates in Plantago major
The impact of ozone (O3) on the production and utilization of photoassimilates was examined in Plantago major population ‘Valsain’. Plants were exposed in controlled environment chambers to either charcoal/Purafil-filtered air (CFA) or CFA plus O3 (15 nmol mol −1 O3 overnight rising to a maximum of 75 nmol mol −1 between 12:00 and 16:00 h). Measurements of leaf gas exchange and non-structural c...
متن کاملOperationally defined apoplastic and symplastic aluminum fractions in root tips of aluminum-intoxicated wheat.
Knowledge of the mechanistic basis of differential aluminum (Al) tolerance depends, in part, on an improved ability to quantify Al located in the apoplastic and symplastic compartments of the root apex. Using root tips excised from seedlings of an Al-tolerant wheat cultivar (Triticum aestivum L. cv Yecora Rojo) grown in Al solutions for 2 d, we established an operationally defined apoplastic Al...
