“…Glucobrassicanapin has been reported to be the predominant GSL in Chinese cabbage [47,48]. However, gluconapin, an aliphatic GSL, was produced in large quantities in B. rapa exposed to fluorescent lamp, blue, and red light in our study.…”

Chinese cabbage (Brassica rapa) is a perennial crucifer vegetable that has long been used for forage. Crucifers are rich sources of glucosinolates (GSLs), which are anti-carcinogenic in humans and involved in plant defense responses. Myeloblastosis (MYB) proteins are a large family of transcription factors (TFs) in plants and play major regulatory roles in many biological processes. We identified 14 functional R2R3-MYB genes involved in glucosinolate biosynthesis in B. rapa ssp. pekinensis. Bioinformatic analysis of their phylogeny, protein motifs, gene interaction network, and molecular characteristics showed that Chinese cabbage MYB genes are comparable to those of Arabidopsis thaliana. The expression levels of the 14 BrMYB genes under fluorescent lamp, blue, and red light were quantitated using qRT-PCR analysis. Almost all of the R2R3-BrMYBs were upregulated and expressed more under red light than under fluorescent lamp or blue light, except BrMYB34s. We also calculated the total GSLs under each light condition. The total GSL content was higher under red light than under fluorescent lamp or blue light. Furthermore, the individual glucosinolates, comprised of four aliphatic GSLs (progoitrin, sinigrin, gluconapin, and glucobrassicanapin) and one indolic GSL (glucobrassicin), were higher under red light than the other light conditions. The relationships between light quality and glucosinolate biosynthesis require further investigation.

“…Light spectrum has a strong effect on the antioxidant properties of horticultural plants [109,110,[133][134][135][136]. For example, UV-B light can cause plant DNA damage, resulting in a cascade of protective events, such as flavonoid synthesis and expression of chalcone synthase genes and photolyase genes [75].…”

Light and Microbial Lifestyle: The Impact of Light Quality on Plant–Microbe Interactions in Horticultural Production Systems—A Review

et al. 2019

Horticultural greenhouse production in circumpolar regions (>60 • N latitude), but also at lower latitudes, is dependent on artificial assimilation lighting to improve plant performance and the profitability of ornamental crops, and to secure production of greenhouse vegetables and berries all year round. In order to reduce energy consumption and energy costs, alternative technologies for lighting have been introduced, including light-emitting diodes (LED). This technology is also well-established within urban farming, especially plant factories. Different light technologies influence biotic and abiotic conditions in the plant environment. This review focuses on the impact of light quality on plant-microbe interactions, especially non-phototrophic organisms. Bacterial and fungal pathogens, biocontrol agents, and the phyllobiome are considered. Relevant molecular mechanisms regulating light-quality-related processes in bacteria are described and knowledge gaps are discussed with reference to ecological theories.

“…Increased accumulation of plant metabolites, both primary and secondary (e.g., soluble sugars, starch, vitamin-C, soluble protein, and polyphenol), was observed in the presence of single-spectral red or blue LEDs when compared with white light ( Table 1 ) [ 20 , 21 , 22 , 23 , 24 , 25 ]. Along with single-spectral red light, the combination of blue and red (red:blue) LEDs also increases the accumulation of primary metabolites, as well as anthocyanin, total polyphenols and flavonoids ( Table 1 ) [ 26 , 27 , 28 , 29 ]. However, red LEDs have a more pronounced effect on anthocyanin accumulation than blue LEDs.…”

“…Light quality affects the photo-oxidative properties of plants by modulating the antioxidant defense system, resulting in the rise of antioxidative enzyme activity. Enhanced antioxidant properties of many vegetables—like, pea, Chinese cabbage, kale, tomato, etc.—have been observed as a response to the use of single-spectral or combined red (625–630 mm):blue lights (465–470 mm), when compared with white light sources ( Table 1 ) [ 23 , 24 , 29 , 38 , 58 ]. Moreover, green (510 nm), yellow (595 nm) or even mixed red:white LEDs also increase both antioxidant properties and anthocyanin accumulation ( Table 1 ) [ 30 , 34 , 55 ].…”

An Overview of LEDs’ Effects on the Production of Bioactive Compounds and Crop Quality

Light-emitting diodes (LEDs) are characterized by their narrow-spectrum, non-thermal photon emission, greater longevity, and energy-saving characteristics, which are better than traditional light sources. LEDs thus hold the potential to revolutionize horticulture lighting technology for crop production, protection, and preservation. Exposure to different LED wavelengths can induce the synthesis of bioactive compounds and antioxidants, which in turn can improve the nutritional quality of horticultural crops. Similarly, LEDs increase the nutrient contents, reduce microbial contamination, and alter the ripening of postharvest fruits and vegetables. LED-treated agronomic products can be beneficial for human health due to their good nutrient value and high antioxidant properties. Besides that, the non-thermal properties of LEDs make them easy to use in closed-canopy or within-canopy lighting systems. Such configurations minimize electricity consumption by maintaining optimal incident photon fluxes. Interestingly, red, blue, and green LEDs can induce systemic acquired resistance in various plant species against fungal pathogens. Hence, when seasonal clouds restrict sunlight, LEDs can provide a controllable, alternative source of selected single or mixed wavelength photon source in greenhouse conditions.
