referenceSpaninks et al. (2020) conducted a comparative analysis of how red and blue light regulate early plant development in Arabidopsis thaliana and Solanum lycopersicum.
claimRed and blue light regulate plant growth and development by influencing root, stem, leaf, flower, and fruit growth, seed germination, water and mineral absorption, photosynthetic pigments, stomatal formation, and sugar metabolism, as reported by Park and Jeong (2023), Bueno and Vendrame (2024), Vatistas et al. (2024), and Wang et al. (2024b).
claimBlue light exposure promotes the morphogenesis, differentiation, growth, and development of the substrate in Cordyceps militaris, while also increasing the content of cordycepin and cordyceps polysaccharide, according to Wang et al. (2014).
measurementCommon bean plants grown under blue light show accumulation of nitrogen (N), copper (Cu), boron (B), and zinc (Zn).
claimIn Anoectochilus roxburghii, blue light significantly increases fresh weight, dry weight, and chlorophyll a content, while yellow light significantly increases the content of soluble sugars and polysaccharides.
claimBlue light signaling regulates secondary cell wall biosynthesis in plant fiber cells during inflorescence stem growth.
referenceWu et al. (2024) studied the effect of red, blue, and amber light-emitting diodes (LEDs) on photosynthesis and plant growth parameters.
referenceTrivellini et al. (2023) examined the role of blue and red light in orchestrating secondary metabolite production, nutrient transport, and overall plant quality.
claimSupplemental light, specifically blue, red, and blue/red light, mitigates the negative effects of salinity and alkalinity stress on plant photosynthetic efficiency and enhances plant resilience.
claimPlants primarily absorb red and blue light to serve as the basic energy source for photosynthesis.
referenceThe spectral effects of three types of white light-emitting diodes on plant growth and development depend on the absolute versus relative amounts of blue light provided.
claimBlue light treatment contributes to the accumulation of Ganoderma lucidum polysaccharide content, which is significantly higher in the bud stage and the opening umbrella stage compared to the white light control group.
referenceWang et al. (2023) found that blue light regulates cell wall structure and carbohydrate metabolism in soybean hypocotyls.
claimBlue light promotes the structural composition of plant cell walls and the accumulation of nonstructural carbohydrates by modulating the expression of associated enzymes and metabolites.
claimIn Mentha pulegium, red light increases internode length while decreasing leaf length, leaf area, and carotenoids; conversely, blue light increases leaf area and root length, according to Roosta et al. (2023).
referenceXu et al. (2021) found that blue light-dependent interactions of the protein CRY1 with GID1 and DELLA proteins regulate gibberellin signaling and photomorphogenesis in Arabidopsis.
measurementAmaranth plants grown under red or blue light show accumulation of sodium (Na) and potassium (K) minerals.
claimZhao et al. (2024b) investigated photomorphogenesis and photosynthetic trait changes in melon seedlings in response to red and blue light.
referenceWang et al. (2024b) studied the effects of red and blue light on the growth, photosynthesis, and subsequent growth under fluctuating light conditions in cucumber seedlings.
claimIn grape skins, where fructose, glucose, and sucrose are the primary sugars, blue light treatment results in the highest total sugar content, followed by red light treatment, according to Kondo et al. (2014).
referenceHexokinase, encoded by the gene HXK1, is located in the mitochondria and performs catalytic fructose phosphorylation, a process promoted by blue light.
claimRed light accelerates stem elongation, while blue light facilitates biomass accumulation as well as leaf and root growth; however, a combination of red and blue light increases plant height, stem thickness, total leaf area, stomatal aperture, crown width, and total root length, according to Si et al. (2024) and Zhao et al. (2024b).
claimBlue light triggers the opening of ion channels in plant cell membranes by regulating the phototropin receptor, which facilitates the uptake and accumulation of mineral nutrients.
claimIn saffron, blue light increases the production of high-quality daughter bulbs and alters biomass allocation, while high red light stimulates the production of lateral buds and induces vegetative leaf production; additionally, an increased blue/red light ratio induces the production of heavier flower bulbs, as found by Moradi et al. (2021).
referenceWang et al. (2014) studied the monosaccharide composition of intracellular polysaccharide and the contents of cordycepin and cordyceps polysaccharide produced by the fungus Cordyceps militaris when induced by blue light.
claimIn soybean plants, exposure to blue light increases the cross-sectional area of hypocotyls and xylem, decreases the longitudinal length of pith cells, inhibits hypocotyl elongation, and increases diameter, as reported by Wang et al. (2023).
measurementSeed stimulation with blue light results in seed germination rates of up to 180% according to Atta et al. (2023).
claimIn current plant research, red and blue light are the most frequently utilized wavelength regions for studying the effects of light quality on plant growth.
claimZhang et al. (2018) demonstrated that blue light regulates secondary cell wall thickening in Arabidopsis by activating the NST1-directed transcriptional network via MYC2/MYC4.
claimIn tobacco plants, blue light increases total soluble sugar and reducing sugar content compared to white light, whereas red and green light decrease reducing sugar content, according to Yang et al. (2017).

claimIncreased blue light content stimulates stomatal opening and promotes photosynthetic electron transfer activity, which leads to higher photosynthetic rates.
claimYang J. L., Song J. N., and Jeong B. R. (2024) observed that the flowering and runnering of seasonal strawberry are affected by the intensity of supplemental or night-interrupting blue light under different photoperiods.
