“…Shading also changed the synthesis of secondary metabolites in plants. Previous studies showed that the light intensity affected the accumulation of flavonoids, phenolics, alkaloids, and lignin in medicinal plants (Poolman et al 2013, Kong et al 2016, Pan and Guo 2016, Arena et al 2017, Lazzarini et al 2018. Light intensity affects synthesis of the secondary metabolites in the medicinal plant by regulation of secondary metabolic pathways.…”

In this investigation, we used the growth, photosynthetic physiological parameters, and targeted metabolite analysis to evaluate the responses of Eleutherococcus senticosus in different shading treatments. The results showed that the moderate shading treatment (Z1) promoted the growth and inhibited photosynthesis of plants. The severe shading treatment (Z2) inhibited both the growth and photosynthesis of the plants. Besides, Z1 had no significant effect on the PSII, while Z2 inhibited the PSII. Most of the eight medicinal metabolites accumulated in the Z1. The C6C1-and C6C3-type phenolics accumulated in the Z1, and the C6C3C6-type in the Z2. In conclusion, the moderate shading treatment accumulated more defensive phenolics; this might be the reason for this shading condition promoting the growth and the accumulation of medicinal metabolites of the plant. The result of this study laid a theoretical foundation for the further study of shading treatments on the secondary metabolism of Eleutherococcus senticosus.

“…Similarly, the green and red LEDs enhanced the contents of sesquiterpenes and monoterpene sabinene in in vitro cultures of Achillea millefolium ( Alvarenga et al, 2015 ). The red light elicited the levels of carvacrol content in Plectranthus amboinicus ( Silva et al, 2017 ), whereas the application of blue light significantly increased the carvacrol content in Lippia gracilis ( Lazzarini et al, 2018 ). The blue light enhanced the myrcene and limonene contents in in vitro -grown Lippia rotundifolia , whereas the combination of red and blue lights in 1:2.5 ratio increased the z-ocimenone metabolite content ( de Hsie et al, 2019 ).…”

The current study has determined the effect of red and blue lights on the enhancement of growth, antioxidant property, phytochemical contents, and expression of proteins in Scrophularia kakudensis. In vitro-grown shoot tip explants of S. kakudensis were cultured on the plant growth regulator-free Murashige and Skoog (MS) medium and cultured under the conventional cool white fluorescent lamp (control), blue light-emitting diodes (LED) light, or red LED light. After 4 weeks, growth, stomatal ultrastructure, total phenols and flavonoids, activities of antioxidant enzymes, and protein expressions were determined. Interestingly, blue or red LED treatment increased the shoot length, shoot diameter, root length, and biomass on comparison with the control. In addition, the LED treatments enhanced the contents of phytochemicals in the extracts. The red LED treatment significantly elicited the accumulation of flavonoids in comparison with the control. In accordance with the secondary metabolites, the LED treatments modulated the activities of antioxidant enzymes. Moreover, the proteomic insights using two-dimensional gel electrophoresis system revealed the proteins involved in transcription and translation, carbohydrate mechanism, post-translational modification, and stress responses. Taken together, the incorporation of blue or red LED during in vitro propagation of S. kakudensis can be a beneficial way to increase the plant quality and medicinal values of S. kakudensis.

“…For example, irradiation with blue and red LED combinations resulted in enhanced biomass during the in vitro culture of Achillea millefolium [ 115 ], Densribium [ 1 ], blueberries [ 114 ], sugarcane [ 110 , 116 ], and chrysanthemum [ 26 ]. In addition to biomass, chlorophyll content was increased in different plant species cultured under LED irradiation [ 24 , 42 , 117 , 118 , 119 ]. In similar studies, increased total carotenoid level was reported in shoot cultures irradiated with different LEDs [ 119 , 120 , 121 ].…”

Application of Light-Emitting Diodes for Improving the Nutritional Quality and Bioactive Compound Levels of Some Crops and Medicinal Plants

Light is a key factor that affects phytochemical synthesis and accumulation in plants. Due to limitations of the environment or cultivated land, there is an urgent need to develop indoor cultivation systems to obtain higher yields with increased phytochemical concentrations using convenient light sources. Light-emitting diodes (LEDs) have several advantages, including consumption of lesser power, longer half-life, higher efficacy, and wider variation in the spectral wavelength than traditional light sources; therefore, these devices are preferred for in vitro culture and indoor plant growth. Moreover, LED irradiation of seedlings enhances plant biomass, nutrient and secondary metabolite levels, and antioxidant properties. Specifically, red and blue LED irradiation exerts strong effects on photosynthesis, stomatal functioning, phototropism, photomorphogenesis, and photosynthetic pigment levels. Additionally, ex vitro plantlet development and acclimatization can be enhanced by regulating the spectral properties of LEDs. Applying an appropriate LED spectral wavelength significantly increases antioxidant enzyme activity in plants, thereby enhancing the cell defense system and providing protection from oxidative damage. Since different plant species respond differently to lighting in the cultivation environment, it is necessary to evaluate specific wavebands before large-scale LED application for controlled in vitro plant growth. This review focuses on the most recent advances and applications of LEDs for in vitro culture organogenesis. The mechanisms underlying the production of different phytochemicals, including phenolics, flavonoids, carotenoids, anthocyanins, and antioxidant enzymes, have also been discussed.
