Selenium and Nano-Selenium for Plant Nutrition and Crop
Selenium and nano-selenium have been investigated by several researchers over more than 200 years, since Se was discovered by Jöns Jacob Berzelius in 1817. The field of plant nutrition was one of the most important fields to investigate Se, which discussed the biological role of Se and nano-Se from their essentiality for plants to The ubiquitous signaling molecule melatonin (N-acetyl-5-methoxytryptamine) (MT) plays vital roles in plant development and stress tolerance. Selenium (Se) may be phytotoxic at high concentrations. Interactions between MT and Se (IV) stress in higher plants are poorly understood. The aim of this study was to evaluate Protective mechanisms of melatonin against selenium toxicity in

Review on environmental selenium: Occurrence, public health
1. Introduction. Selenium (Se) was first discovered by Swedish scientist Jons Jakob Berzelius in 1817, where its chemical properties looks like those of sulfur (Fordyce, 2007).Se can be present in different forms such as selenate, Se(VI); selenite, Se(IV), selenide, Se(II), and its elemental form (Lenz et al., 2008; 2009).Unlike excessive Selenium resembles sulfur (S) chemically and shares a similar pathway for uptake and translocation in plants. For example, SeO 3 2− and SeO 4 2− are analogs of SO 3 2− and SO 4 2−, respectively.Therefore, they can compete with each other in acidic conditions (Golob et al., 2016; González-Morales et al., 2017).Among the Se species, Selenium in plants: Boon or bane?

For all my projects written in python where I use selenium to scrape websites I can only run the script from my own machine and if I were to send the script to a client if say he needed it to run on a daily basis, it most probably wouldn't work. Is there a way to use selenium webdriver in a way for the script to be portableSelenium in the form of selenoproteins is formed through a unique translocation recoding pathway and plays a vital role in human metabolism. Selenium nanoparticles (SeNPs) when synthesized using green synthesis from plant extract offer more advantages than physical and chemical methods.

Selenium in plants: Molecular, Physiological, Ecological and
Plant Se accumulation is very relevant for environmental and human health. Selenium is both essential at low levels and toxic at high levels, and both Se deficiency and toxicity are problems worldwide. Selenium can positively affect crop productivity and nutritional value. Plants may also be used to clean up excess environmental Se.Selenium is an essential trace element which plays an important role in human immune regulation and disease prevention. Plants absorb inorganic selenium (selenite or selenate) from the soil and convert it into various organic selenides (such as seleno amino acids, selenoproteins, and volatile selenides) via the sulfur metabolic Advances in Research on the Involvement of Selenium in Regulating Plant

Selenium and Nano-Selenium-Mediated Drought Stress Tolerance in Plants
Selenium, a unique element, was earlier not contemplated to be a major element involved in mitigation of plant abiotic stresses. It was not until the middle of the twentieth century that its importance was recognized (Schwarz and Foltz 1957; Hasanuzzaman et al. 2010).Several studies on human and animal health, particularly Plants are able to take up both inorganic and organic forms of selenium via active membrane transporters. Inorganic selenium is present in the environment in five valence states, selenide [Se 2− (II)], selenium [Se (0)], thioselenate [Se 2 O 3 2− (II)], selenite [SeO 3 2− (IV)], and selenate [SeO 4 2− (VI)].
