There are evidences of beneficial effects of selenium (Se) on plant growth. In this work, using alfalfa ( Medicago sativa L.) and two varieties of Brassica oleracea L. (cabbage and kohlrabi), the effect of Se addition (10 and 20µM) on growth and concentration of sulfur and Se was investigated in hydroponic experiments. In order to study the involvement of Se-mediated changes in the antioxidant capacity of plants in growth promotion by Se, the activity of antioxidant enzymes including ascorbate…

Effect of salinity on Brassica rapa var. toria (BRSRT) under selenium defence: A trial to assess the protective role of selenium
The present study assesses the role of selenium, an antioxidant in salt-stressed plants. A hydroponic trial of sodium selenate (Na 2 SeO 4 ) on the growth, oxidative stress and antioxidant protection
Sodium selenite treatment of vegetable seeds and seedlings and the effect on antioxidant status
Selenium is an element applied to plants to improve the response to stress and increase their content in the edible parts. The aim of this study was to perform selenium applications in seeds and
Role of sulphate ( SO 4 2-) in improvement the growth of rocket plants ( Eruca sativa L . ) under selenate ( SeO 4 2-) levels
Selenium is an essential microelement for plant growth and productivity, but high selenium levels impose toxicity in plants. A pot experiment was conducted to investigate the role of sulphate
Morpho-physiological effect of selenium on salinity-stressed wheat (Triticum aestivum L.)
TLDR
The study revealed that Se increased production/expression of superoxide dismutase and catalase enzymes under salinity stress, thus growth of wheat plants was improved, and farmers are encouraged to prime wheat seeds with 150 mg/L Se when cultivating saline soils.
Senescence is delayed by selenium in oilseed rape plants.
Selenoamino Acid-Enriched Green Pea as a Value-Added Plant Protein Source for Humans and Livestock
TLDR
Agronomic biofortification using the appropriate chemical form and concentration of Se will have positive effects on green pea growth and its enriched shoots and seeds provide a value-added protein source for livestock and humans with significant increased selenomethionine.
Plant growth and steviol glycosides as a ff ected by foliar application of selenium , boron , and iron under NaCl stress in Stevia rebaudiana Bertoni
Stevia (Stevia rebaudiana Bert.) is well known for its high content of sweet steviol glycosides (SVglys) in its leaves (about 4–20% of dry weight) depending on the environmental, climatic, and growth
Effect of Selenium Enrichment and Type of Application on Yield, Functional Quality and Mineral Composition of Curly Endive Grown in a Hydroponic System
TLDR
Assessment of the effect of Se application rate and type (fertigation or foliar spray) on yield, functional properties and mineral composition of curly endive grown in a hydroponic system indicates that a consumption of 47.4 g day−1 of Se-enriched curly endives grown in soilless culture and treated with 8 μmol L−2 of selenate applied via foliar Spray could be sufficient to cover the human physiological needs of this element.

Interactions between selenium and sulphur nutrition in Arabidopsis thaliana.
TLDR
The data suggest (i) that Se and S enter Arabidopsis through multiple transport pathways with contrasting sulphate/selenate selectivities, whose activities vary between plants of contrasting nutritional status, (ii) that rhizosphere sulphate inhibits selenate uptake, (iii) thatrhizosphere selenates promotes sulphate uptake and (iv) thatSe toxicity occurs because Se andS compete for a biochemical process, such as assimilation into amino acids of essential proteins.
SELENIUM IN HIGHER PLANTS.
TLDR
Recent advances in the understanding of the plant's ability to metabolize Se into volatile Se forms (phytovolatilization) are discussed, along with the application of phytoremediation for the cleanup of Se contaminated environments.

TLDR
Compared with N. tabacum, oxidative damage may be minimised in A. bertolonii roots by high endogenous activities of catalase and, to a lesser extent, superoxide dismutase andCatalase, and enhanced mechanisms for tolerating active oxygen species may also be present.
