Selenium in plants and soil

Some plants can safely accumulate very large amounts of selenium while others cannot so do not be surprised if adjacent plants are affected in different ways. A soil test can confirm toxic levels of selenium in the soil and a tissue test can confirm toxic levels of selenium in plants. Guidelines may differ in your area but generally, if the

Selenium Health Professional Fact Sheet

Mar 11, 2020· The selenium content of soil affects the amounts of selenium in the plants that animals eat, so the quantities of selenium in animal products also vary [2,5]. However, selenium concentration in soil has a smaller effect on selenium levels in animal products than in plant-based foods because animals maintain predictable tissue concentrations of

Selenium forms and methods of application differentially

Selenium (Se) is an essential microelement for humans and a beneficial element for plants. Recently, biofortification with Se has emerged as a key strategy to increase crop Se content. Nonetheless, Se species matters a lot as inorganic Se species is mostly toxic to human health. In this study, we in

Study on the Relationship between Soil Selenium and Plant

Various extraction methods have been used to determine selenium (Se) concentrations in soils and plants in the second seleniferous regions of China. Our results show tea Se contents in the study area range from 1.009 to 2.6 mg/kg, which reveal that the tea areas in Ziyang County are in seleniferous regions. The four extraction methods evaluated in this study provide different information

Selenium in higher plants: understanding mechanisms for

Aug 01, 2009· Selenium (Se) is an essential micronutrient for many organisms, including plants, animals and humans. As plants are the main source of dietary Se, plant Se metabolism is therefore important for Se nutrition of humans and other animals. However, the concentration of Se in plant foods varies between areas, and too much Se can lead to toxicity.

Selenium and nano-selenium in plant nutrition SpringerLink

Oct 20, 2015· Selenium (Se) is a naturally occurring metalloid element which occurs nearly in all environments. Se is considered as a finite and non-renewable resource on the Earth. The common sources of Se in earth’s crust occur in association with sulfide minerals such as metal selenide, whereas it is rarely found in elemental form (Se0). While there is no evidence of Se need for higher plants,

Uptake, translocation and biotransformation of selenium

Jul 23, 2020· 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 comparison with selenite and selenate, were

Selenium accumulation by plants Annals of Botany

Dec 29, 2015· 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 (Fairweather-Tait et al., 2011;

SELENIUM IN HIGHER PLANTS Annual Review of Plant Biology

Abstract Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with regard to

Selenium Fact Sheet for Consumers

Dec 10, 2019· Selenium is found naturally in many foods. The amount of selenium in plant foods depends on the amount of selenium in the soil where they were grown. The amount of selenium in animal products depends on the selenium content of the foods that the animals ate. You can get recommended amounts of selenium by eating a variety

Selenium content, influential factors within the plant and

The paper collected relevant literatures on selenium and explored the function to plant, selenium content, influential factors and selenium specification and transformation. We believed that there should be more deep research on function of selenium to plant. Approaches of molecular, genetic engineering and isotope could be employed to breed selenium rich crops and possibilities in practice.

Accumulation of Selenium in Plants Grown on Selenium

Clipping of plants significantly (P < 0.05) increased the accumulation of Se in the total harvested shoot tissue for wild brown mustard and slightly for the other species tested (except Old Man saltbush). Reduction in soil Se was observed for each species, with the greatest reduction occurring when plants of wild brown mustard were grown and
