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).
claimRed light exposure promotes plant growth and sugar accumulation in Phalaenopsis, according to Anuchai and Hsieh (2017).
referenceFructokinase, encoded by VmFKs genes, is located in the cytoplasm and chloroplast and performs catalytic fructose phosphorylation, a process promoted by red light.
referenceSucrose synthase, encoded by genes VvSWEET10, VvSUC11, and VvSUS4, is located in the cytoplasm and mitochondria and catalyzes the conversion of sucrose to UDP-glucose and fructose, a process promoted by red light.
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.
claimRed light promotes radial elongation, increases stomatal density, and increases glucose, sucrose, fructose, and starch content in leaves, as well as cellulose content in stems in cassava (Zhou et al., 2023).
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.
claimRed light results in shorter fenestrated cells and denser chloroplasts and starch granules in cassava, likely because light quality regulates chlorophyll accumulation by altering the expression of the MeLHCA gene, thereby affecting photosynthetic efficiency (Zhou et al., 2023).
referenceInvertase, encoded by INVs genes, is located in the cytoplasm and vacuole and catalyzes the conversion of sucrose to glucose, a process promoted by red light.
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).
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).
measurementLettuce plants grown under red light show accumulation of potassium (K), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn).
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).
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).
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.
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).
measurementDill plants grown under red light show accumulation of phosphorus (P), potassium (K), calcium (Ca), and zinc (Zn).
claimRed light promotes the uptake of water and minerals by plant root systems, facilitating the transportation and utilization of minerals within plants.
