Furthermore, the factors influencing Se accumulation in plants were elaborated, including internal factors, that is the genetic background and species characteristics of plants; the external factors, that is the soil physiological and biochemical properties, microbial environment, etc. focus on how different factors affect plant Se …
This work aimed to assess the total Se content and Se speciation in Se-enriched soybean grains produced under different Se application methods in the field.
Abstract—We present a literature review of the significance of selenium in plants, animals, and humans. The selenium concentrations in soils with different compositions and from different regions in Russia are reported. The issue of the selenium content of plants, the main source of this element for humans, is consid-ered.
Selenium bioavailability and uptake as affected by four different plants in a loamy clay soil with particular attention to mycorrhizae inoculated ryegrass. Journal of Environmental Radioactivity, 97, 148–158.
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 soil–plant systems of an agricultural production area, elucidate the dynamic mechanisms relating to Se content in plants and soil during …
After being absorbed by plants, different forms of Se are assimilated into selenium amino acids and enter the food chain [60]. Increasing the Se content in the edible sections of crops using inorganic and organic Se fertilizers is a safe, practical, and cost-effective agricultural practice [67].
Till date although the proof of essentiality for selenium (Se) in plants is not established, there exists numerous reports depicting its beneficial effects on plant growth.
In this study, three japonica rice varieties—Nanjing 9108, Jiahua 1 and Wuyunjing 29—were supplied with different levels of nano-foliar selenium fertilizers (0, 40 and 80 kg Se ha−1) under field conditions. Their rice yield and absorption, accumulation, transportation and utilization of selenium were studied to find suitable selenium-rich …
Selenium is an essential element that determines the proper life functions of human and animal organisms. The content of selenium in food varies depending on the region and soil conditions. Therefore, the main source is a properly selected diet. However, in many countries, there are shortages of this element in the soil and local food.

Effects of selenium content in green parts of plants on the amount of ATP and ascorbate-glutathione cycle enzyme activity at various growth stages of wheat and oilseed rape
Selenium content (mg kg −1) ( A) and selenium recovery (%) ( B) in soybean grains from biofortified plants growing under different methods of selenium application.
Selenium (Se), which can be both hazardous and beneficial to plants, animals and humans, plays a pivotal role in regulating soil-plant-human ecosystem functions. The biogeochemical behavior of Se and its environmental impact on the soil-plant-human system has received broad attention in the last decades.
Note: a e, b f, c g, and d h represent the effect size of selenium fertilizer application in the form of selenate, selenite, organic selenium and nano-selenium, different selenium application rates on wheat yield and grain selenium content.
The selenium content of soil affects the amount of selenium in the plants that animals eat. However, this does not substantially affect the amount of selenium in animal products because animals maintain predictable tissue concentrations of selenium through homeostatic mechanisms [ 3, 6 ].
The effects of different selenium sources on the mineral nutrient content, antioxidant enzyme activity, and quality parameters content in leaves were analyzed.
However, it is not clear how each method and source affect the total Se content or Se species in soybean grains. This work aimed to assess the total Se content and Se speciation in Se-enriched soybean grains produced under different Se application methods in the field.
Selenium (Se) is a widely distributed trace element with dual (beneficial or toxic) effects for humans, animals, and plants. The availability of Se in the soil is reliant on the structure of the parental material and the procedures succeeding to soil formation. Anthropogenic activities affect the content of Se in the environment.
The study focused on evaluating the effects of foliar spraying of glucosamine selenium (GLN-Se) on summer-autumn tea. This foliar fertilizer was applied to tea leaves to assess its impact on plant development, nutritional quality, elemental uptake, organoleptic quality, and antioxidant responses.
Recent studies provide increasing amounts of information on the biological activity of selenium (Se) in plants. Although this element is not essential for plants, it has been classified as a beneficial element due to its documented positive role in some plant...
Selenium is a micronutrient with a wide range of functions in animals, including humans, and in microorganisms such as microalgae. However, its role in plant metabolism remains ambiguous. Recent studies of Se supplementation showed that not only does it increase the content of the element itself, but also affects the accumulation …
Plants easily absorb selenium from the soil and in most cases there is a linear relationship between selenium content of soils and its accumulation in plant tissues [3].
The evaluation of the limits between toxicity and deficiency is a problem with a difficult approach, as selenium toxicity and deficiency are influenced by bioavailability of selenium species in the environment, a factor entangled with many environmental variables, and by the bioaccumulation of selenium in some organisms like plants.
Selenium (Se) as selenite and phosphorus (P) have similarities in uptake and assimilation by plants. Selenium content in cowpea grains might be affected by P, which could affect Se and P concentration in other plant tissues and the biosynthesis of sugars and chlorophyll. This study investigated the effects of Se and P interaction on cowpea …
Selenium (Se) is an essential trace element for humans. Low concentrations of Se can promote plant growth and development. Enhancing grain yield and crop Se content is significant, as major food crops generally have low Se content. Studies have shown that Se biofortification can significantly increase Se content in plant tissues. In …
The composition and form of selenium in the soil have significant effects on the selenium content of crops. In this study, we investigated the selenium absorption pathway in plants by studying the interaction between nitrogen fertilizer and soil selenium. Our results showed that the selenium concentration enrichment factors (CEF) varied …
Selenium (Se) is a microelement that plays an important nutrient role by influencing various physiological and biochemical traits in plants. It has been shown to stimulate plant metabolism, enhancing secondary metabolites and lowering abiotic and biotic stress in plants. Globally, the enormous applications of nanotechnology in the …
Abstract We present a literature review of the significance of selenium in plants, animals, and humans. The selenium concentrations in soils with different compositions and from different regions in Russia are reported. The issue of the selenium content of plants, the main source of this element for humans, is considered. The …
The response of tomato quality variables to selenium fertilizer application methods was different, furthermore, the total soluble solids, sugar-acid ratio, and vitamin C improved the most in soil fertilization, while the concentrations of soluble sugar, titratable acid, and lycopene increased the most in leaf spraying.
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 l-yr period under greenhouse conditions.
