“…In tomato fruits, this direct induction of Se on flavonoid content is also observed, with no change in lycopene content [46]. However, with the foliar application of 1.5 mg/L Na 2 SeO 3 , no changes in the accumulation of this trace element in jalapeño pepper fruits were recorded, but an increase in the content of flavonoid, phenolic compounds, and capsaicin was noted [39]. Therefore, it is relevant to carry out studies on the mechanism by which this trace element induces the synthesis of these bioactive compounds.…”

“…The use of Se nanomaterials as a base fertilizer in soil for lettuce cultivation induced increases in the abundance of quercetin (2.9-fold), rutin (2.7-fold), and coumarin (2.4-fold) [38]. In jalapeño pepper fruits, the content of phenolic compounds and total flavonoids increases as higher Na 2 SeO 3 concentration is applied and correlates with the observed antioxidant capacity [39]. Selenium, in the form of Na 2 SeO 4 , also stimulated the production of phenolic compounds, flavonoids, and anthocyanins, as well as the expression of biosynthetic enzymes (phenylalanine ammonium lyase and chalcone synthase) in Indian mustard leaves [40].…”

Selenium (Se) is essential for humans. This element is present in more than 25 proteins related to redox processes, and its deficiency is related to the onset of chronic diseases. One way to incorporate Se into the human diet is by consuming plant foods rich in Se. Crop fortification with Se can be achieved through the agronomic practice of biofortification. This chapter discusses dietary sources of inorganic Se (selenate and selenite), organic Se (selenocysteine, selenomethionine, and methylselenocysteine), and bioactive compounds provided by consuming the edible parts of plants as a result of agronomic biofortification. The benefits to human health from consuming selenium-enriched crops due to their biological functions such as antioxidant, anti-inflammatory, and anticarcinogenic are also presented. The intake of Se-enriched plant foods is a growing trend. In addition to providing the daily dose of Se, these Se-enriched vegetables are a functional food option that improves human health due to their content of phytochemical compounds.

“…The enhancement in the chili plant growth and biomass might be due to the reduction of ROS production and the enhancement of the antioxidant defense mechanism, they promote plant development [42,43]. Humic acid and selenium, however, have a favorable impact on the structural changes imposed by Cdcontent-related stress in chilies in terms of maintaining plant integrity [44,45]. By enhancing the environment for the growth of chili plants, humic acid, and selenium addition plays a crucial part in reducing the stress conditions caused by Cd in plants.…”

Maximizing food production under adverse conditions is a major challenge to food security and sustainability in the face of population growth and climatic change. The use of amendments applied as a supplement under adverse conditions may play a significant role in the mitigation of biotic and abiotic stress. This study aimed to explore the morpho-physio-biochemical changes in chili in response to cadmium (Cd) stress. The present study investigated the effects of foliar-applied selenium (Na2SeO4) (3 µM) and soil-applied humic acid (250 mg kg−1 w/w soil) in the sole and synergistic form under varying levels of cadmium stress (0, 2, and 4 mM using CdCl2) in chili. Results revealed that a linear decrease was noticed in the growth, biomass, and phenological attributes of chili plants by increasing the Cd stress. More reduction was noticed at the higher levels of Cd stress as compared to control due lowering plant dry weight (18.15 and 39.67%), relative water content (RWC) (10.73 and 24.17%), total chlorophyll concentrations (16.01 and 31.44%) and increased electrolyte leakage (49.44 and 129.35%) and malonaldehyde contents (MDA) (68.41 and 104.04%). Dry biomass significantly increased with humic acid and selenium treatments, regardless of cadmium level. The reduced enzymatic activities associated with reactive oxygen species (ROS) detoxification, underscores the pivotal role of Se and humic acid in maintaining redox homeostasis. The combined effect of selenium and humic acid proved better results as compared to the sole application in minimizing Cd uptake in roots and fruit. This study demonstrates that the application of humic acid and selenium activates physio-biochemical defense responses against cadmium stress in chili plants and provides significant pavement for the cultivation of chili in cadmium-containing soils with a target of high-yielding and quality.

“…Selenium is critical because it is necessary to form proteins and be a cofactor of antioxidant enzymes such as glutathione peroxidase (GPX), which reduces reactive oxygen species (ROS). Se deficiency in mammals causes physiological and nutritional deficiencies and pathologies since Se forms at least 25 selenoproteins that fulfill antioxidant, antiviral, and antitumor functions [29][30][31]. The synthesis and application of selenium nanoparticles (SeNPs) present several advantages, including chemical stability, biocompatibility, low toxicity, increased bioactivity, improved targeting, and versatile means to control the release profile.…”

Los forrajes son la columna vertebral de la agricultura sostenible y contribuyen significativamente a la economía mundial, ya que se estima que la superficie de los pastizales es el doble que la de las tierras de cultivo, y los pastos forrajeros ocupan más superficie que cualquier otro cultivo y tienen un valor incalculable para la alimentación del ganado, especialmente rumiantes. En la nutrición animal los minerales constituyen un factor fundamental de los nutrientes requeridos; tal es el caso de los rumiantes, que desde hace muchos años han sido objeto de diferentes investigaciones, especialmente los macrominerales (Ca, P, Mg, K y Na) y algunos oligoelementos como Cu, Co, I, Zn y Se. El selenio (Se) es un oligoelemento esencial para la nutrición animal, que requiere de 40 a 700 µg, lo cual es importante para las funciones biológicas de los animales. El selenio es un componente estructural de más de 30 selenoproteínas, un mineral implicado en diferentes procesos bioquímicos para la vida. La deficiencia de este elemento en los animales se asocia con diferentes alteraciones en el organismo, como disminución de la fertilidad, abortos durante el período de gestación, retención de placenta y debilidad neonatal. Por lo tanto, la nutrición de Se en animales como los rumiantes es de suma importancia ya que el ciclo del Se en la cadena alimentaria de los animales terrestres comienza desde el suelo e influye en las fuentes de alimento de animales como las plantas, que en última instancia dependen de su asimilación del suelo, por lo que son la fuente primaria de Se para las plantas y por ende para los animales, siendo un problema porque la concentración de Se en los suelos varía significativamente. La intervención agrícola que mejora los niveles de Se en plantas cultivadas se ha definido como biofortificación, y ésta puede utilizarse como fertilización y estrategia complementaria para mejorar la nutrición humana y animal.
