Effects of unfavourable environmental conditions (stresses) induce stressor specific and unspecific short- and long-term responses in plants. Long-term responses depend on intensity and duration of the stress. Short-term effects comprise the accumulation of reactive oxygen species (ROS), membrane damages by the oxidation of fatty acids, and the release of(More)
Applied research programs in the remediation of contaminated areas can be used also for gaining insights in the physiological and ecological mechanisms supporting the resistance of plant communities in stress conditions due to toxic elements. The research hypothesis of this study was that in the heavily contaminated but nutrient-poor substrate of mine(More)
The planetary importance of microbial function requires urgently that our knowledge and our exploitation ability is extended, therefore every occasion of bioprospecting is welcome. In this work, bioprospecting is presented from the perspective of the UMBRELLA project, whose main goal was to develop an integral approach for remediation of soil influenced by(More)
Lanthanides are a group of non-essential elements with important imaging and therapeutic applications. Although trivalent lanthanide ions (Ln3+) are used as potent blockers of Ca2+ channels, the systematic studies correlating Ln3+ accumulation and toxicity to Ca2+ channel blocking activity are scarce. In this study, we made use of the eukaryotic model(More)
Blueberries (Vaccinium corymbosum L.) are a rich source of antioxidants and their consumption is believed to contribute to food-related protection against oxidative stress. In the present study, the chemoprotective action of blueberry extracts against cadmium toxicity was investigated using a cadmium-hypersensitive strain of Saccharomyces cerevisiae. Four(More)
The influence of arbuscular mycorrhizal (AM) fungi (Glomus intraradices) and of heavy metal stress on the characteristics of biomass production, as well as non-enzymatic and enzymatic variables in the roots, shoots, and leaves of sunflower (Helianthus annuus L.) plants were studied at pot and field scales. The intensity of the mycorrhizal colonization (M%)(More)
We performed an experiment at pot scale to assess the effect of plant growth-promoting bacteria (PGPB) on the development of five plant species grown on a tailing dam substrate. None of the species even germinated on inoculated unamended tailing material, prompting use of compost amendment. The effect of inoculation on the amended material was to increase(More)
We investigated two Romanian industrial regions- Copşa Mică and Zlatna, to assess the current situation of soil pollution and bioaccumulation of Pb, Cd, Cu and Zn in different vegetable species and possible risks to consumers. Both total and mobile forms of the metals were determined in soil samples, and metal content in the edible parts of root vegetable(More)
Pho84p, the protein responsible for the high-affinity uptake and transport of inorganic phosphate across the plasma membrane, is also involved in the low-affinity uptake of heavy metals in the Saccharomyces cerevisiae cells. In the present study, the effect of PHO84 overexpression upon the heavy metal accumulation by yeast cells was investigated. As PHO84(More)
