“…The amounts of individual compounds from the tested groups increased from 1.51 to 3.38 times (lignin), and from 1.74 to 2.72 times ( phenolic acids), depending on the lighting condition. The results in Table 4 are in harmony with Pedroso et al (2017) when studied the impact of five different lights on rutin accumulation in in vitro cultivated Hyptismarrubioides. They demonstrated the blue and white lights promoted the greatest rutin accumulation (0.30 and 0.31 mg g −1 of dry weight) after 30 days of irradiation.…”

“…Plants have evolved a plethora of signal-transducing photoreceptors that regulate their growth and development in relation to the presence, amounts, direction, duration, and quality of light (Smith 1994;Quail 2002). Plant responses do not depend only on the absence or presence of light but also on the variations in light quality (Pedroso et al 2017). Light quality has important effects on plant growth and development, especially for photosynthesis and photo morphogenesis, the two process that, through signals received by the photoreceptors, regulate plant growth, differentiation, and metabolism (Guo et al 2007).…”

Background: Carob (Ceratonia siliqua L.) is one of the important crops in terms of nutritional and medicinal value in the countries of Western Asia and North Africa. Despite the fact that some countries have used Carob in traditional medicines, the modern food industry began to discover the great potential of this plant which differentiates with antioxidant capacity as well as other important medicinal activities. Some of very few studies that have been reported on this important plant were published. Methodology: In the present study, micropropagation behavior and biochemical constituents of Ceratonia siliqua L. cultured on MS medium supplemented with different types and concentrations of cytokinins (0.0, 0.5, 1.0, or 1.5 mg/l BA, Kin, or TDZ and 0.2 mg/l NAA) under various light qualities ((white, green, blue, red, and yellow) were examined. Results: MS culture medium supplemented with BA produced the highest shootlets number/explants. For light quality, the data showed that green light increased shootlet number/explants, fresh and dry weights. However, yellow light increased shootlet length and leaves number and also caused significant increase in total phenols, flavonoids, and antioxidant capacity (DPPH) as compared to other lights. HPLC analysis showed that yellow light caused the highest accumulation of total phenolic and catechin that were the highest accumulated compounds (509 μg/ml) followed by that were accumulated under green light (412.68 μg/ml). Shootlets grown under white light (control) gave the highest accumulation of p-coumaric acid, rosmarinic acid, and cinnamic acid. Shootlets grown under blue light gave the highest accumulation of gentisic acid and syringic acid. Red light caused the highest accumulation of vanillic acid. However, white light accumulated the highest amount of flavonoid compounds comparing with other light qualities. Conclusion: This study had reached to optimize a suitable micropropagation protocol of Ceratonia siliqua L. and characterization of biochemical constituents that can be beneficial for increasing its medical value which will help in food industries for commercial purposes.

“…Phenotypic plasticity associated with the light and nutrients condition influenced biomass and iridoid glycosides accumulation in Plantago lanceolata offsprings [209]. Its quality influenced growth and flavonoids production in Hyptis marrubioides seedlings cultivated in vitro with red light as the most effective for plant growth and leaves production while blue and white for the promotion of rutin accumulation [210]. Exposure of American ginseng plants to the sunlight at longer duration promoted higher ginsenoside production in roots than those exposed to shorter period of direct sunlight treatments [211].…”

Stress and defense responses in plant secondary metabolites production

2019

In the growth condition(s) of plants, numerous secondary metabolites (SMs) are produced by them to serve variety of cellular functions essential for physiological processes, and recent increasing evidences have implicated stress and defense response signaling in their production. The type and concentration(s) of secondary molecule(s) produced by a plant are determined by the species, genotype, physiology, developmental stage and environmental factors during growth. This suggests the physiological adaptive responses employed by various plant taxonomic groups in coping with the stress and defensive stimuli. The past recent decades had witnessed renewed interest to study abiotic factors that influence secondary metabolism during in vitro and in vivo growth of plants. Application of molecular biology tools and techniques are facilitating understanding the signaling processes and pathways involved in the SMs production at subcellular, cellular, organ and whole plant systems during in vivo and in vitro growth, with application in metabolic engineering of biosynthetic pathways intermediates.

“…Flavonoids are sensitive to light quality, and flavonoid concentrations in plants are higher when grown under UV, blue, and FR light treatment (Fu et al., 2016; Pedroso et al., 2017; Liu et al., 2018). The two-ring, 15-carbon, general structure of flavonoids makes this group structurally and functionally diverse.…”

This review presents recent developments in plant photobiology and lighting systems for horticultural crops, as well as potential applications for cannabis ( Cannabis sativa and C. indica ) plant production. The legal and commercial production of the cannabis plant is a relatively new, rapidly growing, and highly profitable industry in Europe and North America. However, more knowledge transfer from plant studies and horticultural communities to commercial cannabis plant growers is needed. Plant photosynthesis and photomorphogenesis are influenced by light wavelength, intensity, and photoperiod via plant photoreceptors that sense light and control plant growth. Further, light properties play a critical role in plant vegetative growth and reproductive (flowering) developmental stages, as well as in biomass, secondary metabolite synthesis, and accumulation. Advantages and disadvantages of widespread greenhouse lighting systems that use high pressure sodium lamps or light emitting diode (LED) lighting are known. Some artificial plant lighting practices will require improvements for cannabis production. By manipulating LED light spectra and stimulating specific plant photoreceptors, it may be possible to minimize operation costs while maximizing cannabis biomass and cannabinoid yield, including tetrahydrocannabinol (or Δ 9 -tetrahydrocannabinol) and cannabidiol for medicinal and recreational purposes. The basics of plant photobiology (photosynthesis and photomorphogenesis) and electrical lighting systems are discussed, with an emphasis on how the light spectrum and lighting strategies could influence cannabis production and secondary compound accumulation.
