“…Phenolics and flavonoids content increased in the fourth week with 4 h of UV-B exposure per day, and the highest concentrations of quercetin (230 μg/g DW), kaempferol (235 μg/g DW) and gallic acid (240 μg/g DW) were found in callus obtained from leaves explants ( 8 ). Mata-Ramírez et al ( 9 ) evaluated the quantification and bioactivity of isoflavone in soybean callus submitted to UV-light stresses. It was found that UVC-light stress increased genistein-O-glucoside and genistein-O-glucosyl-malonate to 122 and 196% in soybean callus, respectively, resulting in the enhancement of anti-inflammatory and antioxidant activity in calluses.…”

Isoflavones are a class of flavonoids that belong to a large family of polyphenols and synthesized predominantly in legume, and they play important roles including acting as antioxidant, preventing osteoporosis, reducing the risk of atherosclerosis, and protecting against cardiovascular disease. This study focused on the accumulation and synthetic metabolism of isoflavone in soybean hypocotyl and cotyledon calluses under UV-B radiation. The results showed that UV-B radiation significantly up-regulated the gene expression of phenylalanine ammonia lyase (PAL), cinnamate-4-hydroxylase (C4H), 4-coumarate-CoA ligase (4CL), chalcone ketone synthase (CHS), chalcone isomerase (CHI), and isoflavone synthase (IFS), and enhanced their activity in soybean hypocotyl and cotyledon calluses. As a result, isoflavones content increased by 21.23 and 21.75% in soybean hypocotyl and cotyledon calluses, respectively. Among the isoflavones produced, malonyldaidzin was the dominant one in hypocotyl callus, while malonylglycitin and daidzein were the main isoflavones in cotyledon calluses. This study revealed that UV-B radiation induced isoflavone accumulation in soybean calluses, which could be an efficient strategy to improve the nutritional value of food and produce high levels of bioactive secondary metabolites.

“…Conversely, excessive UV-B exposure damaged cells and decreased the amount of isoflavones within them [56]. In cultured soybean, UV-C radiation increased the amount of genistein-Oglucoside and genistein-O-glucosyl-malonate, suggesting in vitro culture to obtain a high level of metabolites [57]. Moreover, in germinated soybean under UV-B radiation, total protein content and endogenous H 2 O 2 were increased [58].…”

Ultraviolet radiation is a portion of the electromagnetic spectrum ranging from 10 to 400 nm, classified into three main categories: UV-A (320–400 nm), UV-B (280–320 nm), and UV-C (100–280 nm). The UV radiation from the sun that crosses the atmosphere and reaches the earth’s surface is composed largely of UV-A radiation (95%) and, to a lesser extent, UV-B (5%), which is normally filtered by stratospheric ozone. With the thinning of the ozone layer, UV-B radiation penetrates deeper into the earth’s surface, where it becomes dangerous due to its high energy content that acts at the molecular level, affecting the cycles of carbon, nitrogen, and other elements, thus, having a direct impact on global warming. On the other hand, UV radiation alters numerous essential organic compounds for living organisms. Since its discovery, it has been established that e UV-B causes alterations in plant development and metabolism, both primary and secondary. In this chapter, we summarize the current knowledge about the effects of UV radiation on the morphological, biochemical, and genetic processes in plants.

“…The former also shows a higher scavenging rate of DPPH radicals and activities of SOD and CAT but lower lipid peroxidation [ 88 ]. Treatment with Na 2 SeO 3 solutions (28.90, 57.80, and 115.6 µmol L −1 ) also increases the isoflavone content and inhibition of NO production in soybean under UV stress [ 89 ]. The antioxidant activity of soybean cells is thus increased.…”

Plant growth is affected by various abiotic stresses, including water, temperature, light, salt, and heavy metals. Selenium (Se) is not an essential nutrient for plants but plays important roles in alleviating the abiotic stresses suffered by plants. This article summarizes the Se uptake and metabolic processes in plants and the functions of Se in response to water, temperature, light, salt, and heavy metal stresses in plants. Se promotes the uptake of beneficial substances, maintains the stability of plasma membranes, and enhances the activity of various antioxidant enzymes, thus alleviating adverse effects in plants under abiotic stresses. Future research directions on the relationship between Se and abiotic stresses in plants are proposed. This article will further deepen our understanding of the relationship between Se and plants.
