AbstractFungal endophytes can improve the growth of plants and are considered as an effective tool for metal remediation. Trametes hirsuta was tested for Cd and Pb tolerance, further Petunia hybrida Vilm. was infected at seedling stage by T. hirsuta and was tested to see the impact of Cd and Pb toxicity. On potato dextrose agar media plates T. hirs...

AbstractIn this work, the effect of exogenous histidine supply on zinc (Zn) and nickel (Ni) translocation to the shoots in intact plants of the hyperaccumulator Noccaea caerulescens F.K. Mey was studied. Three series of experiments were carried out. (1) Intact N. caerulescens plants (St-Félix-de-Pallières population) were pretreated for 4 h (12:00 ...

AbstractIn this work, a comparative analysis of zinc (Zn) accumulation by the excluder Microthlaspi perfoliatum (L.) F.K. Mey, the hyperaccumulator Noccaea japonicum (H. Boissieu) F.K. Mey from ultramafic (serpentine) soil and plants from 19 populations of the hyperaccumulator Noccaea caerulescens F.K. Mey originating from ultramafic, calamine and ...

AbstractA greenhouse experiment was conducted to investigate the expression levels of six ZRT/IRT like-protein (ZIP) genes in roots and leaves of bread wheat cultivars (Triticum aestivum L.) under soil Zn deficiency conditions. ‘Bayat’ and ‘Niknejad’ (Zn-efficient) and ‘Hirmand’ and ‘Karaj1’ (Zn-inefficient) cultivars were grown in soil Zn deficien...

AbstractThe review discusses various toxic effects of heavy metals on the root growth. The advantages of roots as test objects in the search for compounds with pronounced cytostatic action and in studies of heavy metal toxicity are considered. In contrast to the majority of published works, in which metal effect was judged on the basis of single ro...

AbstractSeedlings of wheat genotype HUW-234 (Triticum aestivum L.) were raised in pot soil culture using eight different treatment combinations, enriched with inorganic arsenic (AsV at 0, 30 mg/kg soil), zinc sulphate (Zn at 0, 20 mg/kg soil) and vermicompost (at 0, 15 t/ha). Plants exposed to As toxicity were found significantly (P ≤ 0.05) lower i...

AbstractEnvironmental pollution is serious problem all around the world. Over the past decades, several well-known heavy metals have received much attention of researchers, and new information has been collected on their toxicity. However, knowledge of environmental chemistry of many other potentially toxic trace elements is scarce, though it is kn...

AbstractSeedlings of groundnut (Arachis hypogaea L.) ‘TG-51’ were raised in sand culture in presence of three different concentrations of cadmium (100, 300 and 500 µM) and two concentrations of zinc (50 and 150 µM) along with their combinations. In general, the root accumulated several times higher content of both the metals than leaf. It was noted...

AbstractZinc (Zn) is an essential micronutrient that is crucial to the health of all organisms. Zn absorption through roots system during the grain-filling period and Zn remobilization from pre-anthesis stores of shoot into grains are two main sources of zinc accumulation in grains. Field and solution experiments were conducted to study the Zn effi...
