“…Selenoamino acids appear to be beneficial to growth in some conditions with an underlying influence on the oxidative protection networks in plants (Pilon-Smits and Quinn, 2010;Feng et al, 2013;Ahmad et al, 2016). Different strategies have been adopted to evaluate the role of Se in response to stress, including the application of Se as a seed priming treatment (Hasanuzzaman and Fujita, 2011;Nawaz et al, 2013;Hussain et al, 2016), soil fertilizer (Kumar et al, 2014;Khan et al, 2015;Atarodi et al, 2018), and foliar drench (Iqbal et al, 2015;Shahverdi et al, 2020). Treatment with Se at low concentrations is known to alleviate several stresses in plants, including those ones caused by drought (Hasanuzzaman and Fujita, 2011;Nawaz et al, 2013), heat (Iqbal et al, 2015), arsenic (Kumar et al, 2014), cadmium (Khan et al, 2015), low phosphorus (Jia et al, 2018), salinity (Shahverdi et al, 2020), as well as lead and aluminum (Feng et al, 2013).…”

Selenium (Se) is considered a beneficial element in higher plants when provided at low concentrations. Recently, studies have unveiled the interactions between Se and ethylene metabolism throughout plant growth and development. However, despite the evidence that Se may provide longer shelf life in ethylene-sensitive flowers, its primary action on ethylene biosynthesis and cause-effect responses are still understated. In the present review, we discuss the likely action of Se on ethylene biosynthesis and its consequence on postharvest physiology of cut flowers. By combining Se chemical properties with a dissection of ethylene metabolism, we further highlighted both the potential use of Se solutions and their downstream responses. We believe that this report will provide the foundation for the hypothesis that Se plays a key role in the postharvest longevity of ethylene-sensitive flowers.

“…Moreover, Se can effectively mitigate pests, diseases, plant senescence, and heavy metals, particularly in Cd-stressed plants [ 19 ]. This antagonistic effect is reflected in several crops, such as wheat, rice, and rape [ 20 , 21 , 22 ]. Studies have indicated that proteins in plants can be combined with inorganic Se and converted into nontoxic organic Se for absorption by the human body [ 23 ].…”

Cadmium (Cd) pollution in soil, particularly in peanut production, is a problem that has attracted global concern and needs solutions urgently. Selenium (Se) can alleviate Cd toxicity; however, the underlying mechanisms are not completely understood. Therefore, two varieties of peanut (Arachis hypogaea Linn.), “Huayu 23” and “Huayu 20”, were chosen as the target crops for this study. A pot experiment was conducted to investigate the effects of two Se application methods combined with biochar on the accumulation of Cd and Se, and the best application method was identified. In addition, the role of Se in alleviating Cd toxicity in peanuts was studied. The results indicated that both Se and biochar decreased the Cd content in peanuts and alleviated Cd toxicity. However, the combined application of foliar Se and biochar significantly increased the peanut biomass by 73.44–132.41%, increased the grain yield of Huayu 23 by 0.60–1.09 fold, and Huayu 20 by 2.38–3.48 fold. Additionally, Cd content in peanut grains was decreased by 32.81–50.07%, and Se content was increased by 31.57–99.75 folds. Biochar can decrease the absorption of Cd from the soil, while Se can increase the accumulation of Cd in cell vacuoles by increasing glutathione and phytochelatin to decrease the movement of Cd into the grains. Therefore, our results indicate that the combined application of foliar Se and biochar can effectively promote the enrichment of Se in peanuts and suppress Cd toxicity.
