  • Assessment of bioavailability of selenium in different

      Bioavailability of selenium (Se) depends on its speciation rather than total Se content in soil, and available Se content is a crucial indicator of the mobility and toxicity of Se (Li et al, 2010, Tolu et al, 2011) For this reason, accurate measurement and assessment of Se availability in soil has become a hotspot in Se research  Vegetation management (phytoremediation) may be a strategy to reduce these soil Se concentrations to nontoxic levels Selenium in plant shoots and depletion of soil Se removal by selected plant species were evaluated over a 1yr period under greenhouse conditionsEvaluation of Different Plant Species Used for   Selenium content in food is widely different depending on its concentration in the soil in a given geographical area, the ability of plants to accumulate it, as well as animal feed Other components such as cultivation, climatic conditions, breeding methods, and methods of preparing food products may also have an effect on Se content in food [ 3 ]Quantitative determination of selenium in the most

  • Selenium (Se) uptake and dynamic changes of Se content

    In this study, we collected crop plants and associated soil samples and determined these for selenium (Se) content to analyze the uptake, enrichment, and translocation of Se in the different soilplant systems of an agricultural production area, elucidate the dynamic mechanisms relating to Se content in plants and soil during different growth periods, and screen plants for high Se   Summary In the present study the selenium and chromium content of different plant foods such as fruits, greens, flowers, vegetables, dried fruits, spices, condiments, cereals and pulses were analysedLevels of selenium and chromium in different Journal of Agricultural Resources and Environment (Dec 2014) Selenium Content, Influential Factors Within the Plant and the Transformation of Different Selenium SpecificationSelenium Content, Influential Factors Within the Plant and

  • Selenium accumulation by plants Annals of Botany

    INTRODUCTION: SELENIUM IN SOILS, PLANTS AND ANIMALS Selenium (Se) is an essential mineral element for both human and animal nutrition (White and Brown, 2010)In humans, Se deficiency is associated with hypothyroidism, cardiovascular disease, a weakened immune system, male infertility, cognitive decline and increased incidence of various cancers   Selenium is a metalloid which is close to sulfur (S) in terms of propertiesThe Se concentration in soil varies with type, texture and organic matter content of the soil and with rainfall Its assimilation by plants is influenced by the physicochemical properties of the soil (redox status, pH and microbial activity)Selenium in the Environment, Metabolism and   Selenium (Se) in soil mainly consists of selenite, selenate, and elemental Se However, little is known about the mechanism involved in the uptake and biotransformation of elemental Se by plants In this study, the uptake, translocation, subcellular distribution and biotransformation of selenium nanoparticles (SeNPs) in rice (Oryza sativa L), and a Uptake, translocation and biotransformation of selenium

  • Selenium uptake, translocation and speciation

      Selenium concentrations in the xylem saps of the selenitetreated plants were much lower than those of the selenatetreated plants; in the former Se speciation was dominated by the unidentified compound at RT 27 Small   Selenium content in food is widely different depending on its concentration in the soil in a given geographical area, the ability of plants to accumulate it, as well as animal feed Other components such as cultivation, climatic conditions, breeding methods, and methods of preparing food products may also have an effect on Se content in food [ 3 ]Quantitative determination of selenium in the most   Selenium partitioning across different plant organs is also different for hyperaccumulators: they have higher shoot : root Se ratios and higher source : sink Se ratios, suggesting enhanced Se translocation in xylem and phloem as compared with nonhyperaccumulators (White et al, 2007; Cappa et al, 2014)The fascinating facets of plant selenium accumulation
