“…A long-lasting application of blue light enhances the synthesis of ALA and eliminates the unfavorable effect of red light in this respect (Fan et al 2013). The literature data confirm the inhibitory effect of red light on the production of chlorophyll that we also observed in our study (Li et al 2010;Fan et al 2013;Habiba et al 2014;Bello-Bello et al 2016;Coelho et al 2021), and carotenoids (Liu et al 2011;Fan et al 2013;Pawłowska et al 2018b;Coelho et al 2021) in in vitro plant cultures. RBUV light also inhibited the synthesis of photosynthetic pigments, both chlorophylls and carotenoids, in L. candidum cultures.…”

“…Phenolics biosynthesis in plants is controlled by external factors, including light that may stimulate the process or even be its indispensable component (Ghasemzadeh et al 2010). The main absorption spectrum of flavonoids occurs between 400 and 430 nm, that is the spectrum of blue light by which their production is stimulated (Ebisawa et al 2008;Silva et al 2017;Taulavuori et al 2018;Coelho et al 2021;Rocha et al 2022). The main absorption spectrum for many phenolic compounds matches UVB wavelength and their synthesis is stimulated by UVB light.…”

Lilium candidum L. is a plant with rich cultural traditions and huge potential in floriculture and modern medicine. Our study analyzed the effects of light emitting diodes (LEDs) of variable quality on adventitious organogenesis induced in bulb scales placed on Murashige and Skoog medium. In addition to the spectral compositions of red (100%), blue (100%), and red and blue light (RB ratio 7:3), RB light was mixed in equal proportions (50%) with green (RBG), yellow (RBY), UV (RBUV), and far red (RBfR) light. We also tested white LED (Wled). Fluorescent lamp light (Fl) and darkness (D) served as controls. We assessed the effects of light on the morphometric features as well as the physiological and biochemical quality of the bulblets (adventitious bulbs). Bulb formation was observed under all light qualities, even in darkness, albeit to a limited extent. White LED light (Wled) treatment translated into the highest efficiency of bulblet formation and the greatest number of bulbs with developed leaves. The leaves, even though the shortest ones, also developed as a result of RBG treatment, and this light mixture enhanced the diameter of the forming bulblets. The bulbletsunder this light spectrum accumulated the most chlorophyll and carotenoids. The bulblets formed under B, RBfR and RBG LED had more than two times higher phenoliclevels than those formed under R LED and Fl. The bulbletsformed under B LED were the richest in soluble sugars, similarly to those developing in darkness (D).

Urtica dioica (UD) is a multi-functional plant known to be used as both food and medicine from ancient times. The plant has the potential to be used as a fertilizer and for biological pest control. It is also used in textile and related industries for its quality fibers. In the recent past, the plant has received great attention for its numerous important biological activities and food applications. The antioxidant activity of UD is the crucial factor supporting its important biological activities, such as anticancer, antidiabetic and anti-inflammatory properties. The antioxidant activity of UD is also found to be protective in different organs, including the brain, liver, lungs, kidney, ovary, and uterus, and may also be protective against diseases associated with these organs. Few clinical studies have endorsed the antioxidant potential of UD in patients. The current work is an attempt to comprehensively compile and discuss the antioxidant activity of UD from in vitro, in vivo and human studies. The insights of the current study would be helpful in getting a panoramic view of the antioxidant potential of UD, and provide direction for optimizing and developing it for therapeutic applications against important diseases and conditions in the near future.

I N THIS STUDY, we established of an application protocol for the micropropagation of Dillenia indica with an estimate of betulinic acid from callus, leaf, and regeneration plant. Moreover, the antimicrobial and cytotoxic efficacy of the crude extract and pure compound was compared. The highest number of shoots (3.667 shoots), leaf number per jar (27 leaves) and shoot length (3.667cm) were recorded from the MS medium containing 2.0mg L -1 of benzyl amino purine (BAP). Moreover, different physical elicitors (ultraviolet irradiation, microwave radiation, and light quality) were used on the production and increased the concentration of betulinic acid in callus of D. indica. The data revealed that the highest betulinic acid content (341.775mg/ 100g fresh weight) was recorded in callus microwaved with 200 watts for 10s. Which was three times more than the betulinic acid content recorded in the mother plant. In addition, different crude extracts of D. indica were used to determine their biological activity against six microorganisms. The data showed that the highest diameter of inhibition zones (17.0 mm) was recorded in callus culture extractions incubated under blue light with Candida albicans. The cytotoxic efficacy of betulinic acid and extract of callus, mother plant leaf or in vitro regeneration plants of D. indica were investigated against the Vero cell line by MTT. The results revealed that The IC 50 values were 115.7 ± 9.17, 114.98 ± 5.2, 59.45 ± 3.06, and 72.76 ± 6.93μgmL -1 of betulinic acid, callus extract, leaf, and regeneration plant, respectively.
