“…Polyphenolics as the main compounds of plant secondary metabolism are responsible for protecting plant cells from free radicals and maintaining the balance of active oxygen metabolism by inhibiting reactive oxygen species. The mentioned function is the most pronounced but also closely related to the role of polyphenolic compounds in plant growth and development as a main protection antioxidants [42,43]. Cotyledon phase is a vital and first moment of plant response to the light in the process of photomorphogenesis, while the generation of chloroplast formation as photosynthetically functional organelles and greening (chlorophyll synthesis) are crucial for further plant response to light stress.…”

Microgreens are young plants of various vegetables, medicinal and aromatic plants, cereals and edible wild plants that were first associated with nouvelle cuisine as decoration in dishes due to their attractive appearance and strong flavor. Recently, they have become more sought after in the market due to their high nutritional value. This is due to the growing interest of consumers in a healthy lifestyle that includes a varied diet with emphasis on fresh, functional foods. Nowadays, commercial production of microgreens is shifting to modern hydroponic systems due to their numerous advantages, such as accelerated plant growth and biomass production, earlier harvesting, and more production cycles that positively affect yield and chemical composition. Therefore, the aim of this study was to determine the content of specialized metabolites and antioxidant capacity of hydroponically grown alfalfa (Medicago sativa) cv. ‘Kangaroo’, yellow beet (Beta vulgaris var. conditiva) cv. ‘Yellow Lady’, red cabbage (Brassica oleracea L. var. rubra) cv. ‘Red Carpet’, and fennel (Foeniculum vulgare) cv. ‘Aganarpo’ microgreens. The highest content of total phenols (408.03 mg GAE/100 g fw), flavonoids (214.47 mg GAE/100 g fw), non-flavonoids (193.56 mg GAE/100 g fw) and ascorbic acid (74.94 mg/100 g fw) was found in fennel microgreens. The highest content of all analyzed chlorophyll pigments (Chl_a 0.536 mg/g fw, Chl_b 0.248 mg/g fw, and TCh 0.785 mg/g fw) was found in alfalfa microgreens. However, in addition to alfalfa, high levels of chlorophyll a (0.528 mg/g fw), total chlorophyll (0.713 mg/g fw) and the highest level of total carotenoids (0.196 mg/g fw) were also detected in fennel microgreens. The results suggest that microgreens grown on perlite in floating hydroponics have high nutritional potential as a functional food important for human health and therefore could be recommended for daily diet.

“…The most common secondary metabolites in FFB–SJ are flavonoids, which protect young organs from environmental stresses ( Shah and Smith, 2020 ). Phenolic acids are directly involved in plant growth regulation ( Yu et al, 2021a ) and are important precursors of flavonoid synthesis ( Chen et al, 2021 ). Both flavonoids and phenolic acids are used in clinical applications in humans ( Sharma et al, 2020 ).…”

Sophora japonica L. is widely consumed in China because of its medicinal and nutritional value. Its quality is greatly affected by the accumulation of metabolites, which varies with the stage of flower development. However, changes in the characteristics of the secondary metabolites during flower maturity remain unclear. Ultra-high-performance liquid chromatography coupled with electrospray ionization-triple quadrupole-linear ion trap mass spectrometry (UPLC–ESI–QTRAP–MS/MS) revealed dynamic changes in the secondary metabolites of S. japonica during the five flower-maturity stages. We monitored 331 metabolites and screened 164. The differential metabolites showed seven trends during flower maturation, with flavonoids and phenolic acids having the most varied expressions. Flower buds (S2–S3) are rich in flavonoids and are thus suitable for use in high-quality medicine or industrial extraction. Our study provides an empirical basis for the informed harvesting of S. japonica based on its mode of utilization.

“…6). Consequently, the regulation of related genes was mediated by HY5s, which might stimulate polyphenol biosynthesis of mung bean sprouts in response to light signals, as was found in Catharanthus roseus seedlings (Yu et al 2021). PIFs, constitutive repressors of photomorphogenesis, can interact with photoreceptors to regulate downstream light-responsive factors (Liu et al 2015).…”

“…Light stress can induce the accumulation of reactive oxygen species (ROS) in plants, resulting in photooxidative damage, and polyphenols can improve the tolerance of plants to oxidative stress (Zoratti et al 2014). Accumulation of avonoid compounds in Catharanthus roseus seedling adapted to light stress by effectively suppressing ROS levels (Yu et al 2021). Among detected polyphenols, the concentrations of caffeic acid, rutin, ferulic acid, vitexin, daidzin, genistin and delphinidin 3-glucoside were increased by LQs (Fig.…”

Effect of light quality on polyphenol biosynthesis in three varieties of mung bean sprouts with different color seed coats

et al. 2022

Mung bean (Vigna radiata) sprouts are a popular sprouting vegetable all over the world and are an excellent source of polyphenols with high antioxidant activity. This study investigated the effects of light qualities on the kinetic changes and metabolic regulation mechanism of light signal mediating polyphenols in three mung bean sprout cultivars. Experimental results showed that white light particularly enhanced the contents of caffeic acid, rutin and delphinidin 3-glucoside. Interestingly, ferulic acid and vitexin responded selectively to blue light and red light, severally. Most genes involved in polyphenol biosynthesis were activated under different light quality conditions, resulting in an overaccumulation of phenylpropanoids. Pearson correlation analysis showed that PAL, F3H, F3'H and F3'5'H expression correlated highly with rutin, whereas ANS expression paralleled anthocyanin biosynthesis. Moreover, MYB111, MYB3, MYB4, MYB1 and MYC2 were critical regulators of polyphenol biosynthesis in mung bean sprouts. These changes were likely due to the changes in expression of the photoreceptor genes CRY-D, PHOT2, PHYE and light response genes (PIF3 and HY5). Our results provide insights into polyphenol biosynthesis in sprouts and microgreens. Key MessagesLight quality greatly affected the expression of polyphenol-related and light signaling TFs accompanied by the activation of 16 structural genes in polyphenol synthesis and subsequently resulted in the massive accumulation of polyphenols.
