“…Light was reported to affect the photosynthesis of Arabidopsis thaliana [23], while far red light positively influence the photosynthesis Lactuca sativa [24]. In Camptotheca acuminuta [25], red light can increase the plants biomass, leaf area, specific leaf area, Chl a and b, as well as carotenoid contents. Besides, Anet, stomatal conductance, and transpiration rate also increases under red light treatment.…”

Light is an important environmental factor that have an influence on a plants photosynthesis and production of secondary metabolites like phenolic compounds and flavonoid. Mangifera indica from the family Anacardiaceae is known to have bioactivity due to its phenolic and flavonoid contents. The objective of the study is to determine the influence of light on the photosynthesis and phenolic contents of M. indica. Photosynthesis of the plant was measured using a portable photosynthesis system referred to as LICOR-6400. Photosynthetic pigments as well as phenolic and flavonoid contents were quantified using a UV-VIS spectrophotometer. The outcome derived from the study shows that sun exposed leaves of the studied plant were having the maximum photosynthesis, saturation and compensation points (P < 0.05). Moreover, sun exposed leaves were having higher carotenoid, phenolic and flavonoid contents but lower chlorophyll contents. This leads to a conclusion that sun leaves of M. indica contribute the highest photosynthesis and phenolic contents to the plant.

“…Previous reports have noted the potential influence of narrowwavelength 595 nm light on plant stress tolerance [7,14]. We have shown that 595 nm light regulates genes associated with photosynthetic and antioxidant systems in A. thaliana Col-0 leaves (Yavari et al).…”

“…However, McCree showed that 595 nm light exhibits some of the highest photosynthetic activity of any of the other wavelengths of light tested [13]. Additionally, 595 nm light plays a highly regulatory role in abundance and activity of key proteins that mediate stress tolerance in plant [14]. For instance, 595 nm light induces the abundance/activity of antioxidant enzymes such as superoxide-dismutase (SOD), catalase (CAT), and peroxidase (POD), ultimately reducing the accumulation of free radicals.…”

A growing body of evidence has highlighted that a wide range of plant processes including growth, photosynthesis, and stress response are regulated by 595 nm light. However, the molecular mechanisms underlying 595 nm-induced signals are not known. The aim of this work was to study the comparative proteomic changes in leaves of Arabidopsis thaliana Col-0 plants treated with narrow-wavelength 595 nm light or fluorescent light for 5 days. Harvested plant samples were analyzed using inline RP-SCX-RP liquid chromatography coupled with LTQ mass spectrometer, resulting in the identification of 1538 proteins. Linear regression modeling of proteins' relative abundance revealed a total of 23 differentially abundant proteins (DAPs). Functional analysis of these DAPs demonstrated the role of several biological mechanisms in A. thaliana's response to 595 nm light including stress response and metabolic processes. A network analysis of these DAPs revealed the importance of energy and redox regulation mechanisms. Further analyses determined potentially important roles for proteins associated with glycolysis, ATP synthase complex, cell wall modification, and thylakoid membrane that may modulate the plant's adaptive response to 595 nm light. A significant enrichment of DAPs for PSII tolerance capacity, as well as associated Ca2 + and ROS signaling pathways were also identified. Collectively, this study provides an important insight into potential molecular pathways that sustain a plant's response to 595 nm light.

“…The quality of the light spectrum and the culture medium can influence the morphogenesis process from the entire plant to those grown in vitro. Species like Camptotheca acuminata had their seedlings studied with different qualities of light demonstrating that the development, leaf area, chloroplast development and photosynthetic efficiency were modified by the use of red light rather than blue or yellow light (Yu et al, 2017). In strawberry (Fragaria × ananassa), the total content of anthocyanins increased by the use of red and yellow plastic films, suggesting the activation of enzymes or transcription factors related to the flavonoid pathway (Miao et al, 2016).…”

Alternanthera brasiliana is a medicinal plant with several popular use and high production of betalains. The aim of the present research was to establish a protocol for callus induction and betalain biosynthesis in A. brasiliana species, as well as to investigate the effect of different qualities of light in increasing betalain in A. brasiliana callus cultures. In this way, the callus initiation and the improvement of secondary metabolites were induced using varying phytohormones concentrations and under the influence of red, white and blue lights. To start the experiments, the plants were cultivated for 30 days in Murashige and Skoog (MS) medium to grow and form internodes. These were inoculated in MS medium supplemented with different combinations of plant growth regulators to find the best combination for medium callus induction (MCI). After another 30 days, the explants were transferred to a medium for betacyanin induction (MBI) containing thidiazuron (TDZ) and α-naphthalene acetic acid (NAA) under blue, white, and red lights. The best medium for A. brasiliana callus induction with higher production of betalains, was the MS medium supplemented white indole-3-acetic acid (IAA) and 2,4dichlorophenoxyacetic acid (2,4-D), before inoculation on the MBI. The blue and white lights promoted callus pigmentation (betalains), whereas the red light was not effective at inducing pigmentation in the calli.
