claimPlant osmoregulation is achieved by synthesizing large molecular weight organic matter (such as sugars and alcohols) to improve cell osmotic pressure and enhance water absorption, and by activating photoreceptors via light to act as regulators.

referenceLuo and Keenan (2020) provided global evidence for the acclimation of ecosystem photosynthesis to light.

referenceLight prevents pathogen-induced aqueous microenvironments in plants via the potentiation of salicylic acid signaling.

referenceIn Arabidopsis, sucrose and light regulate the cold-inducible UDP-glucose pyrophosphorylase gene through a pathway that is independent of hexokinase and insensitive to abscisic acid.

claimLight from the top and side improves leaf structure and anatomy, photosynthesis, and chlorophyll fluorescence, while side light specifically promotes plant growth, improves chloroplast arrangement, induces a higher density of small stomata, and promotes stomatal opening and photosynthetic efficiency (Yang and Jeong, 2021).

claimLight acts as an environmental factor that regulates plant growth and development in conjunction with other factors such as water, salinity, and temperature.

claimDuring plant growth and development, light affects stem elongation, leaf size, flower opening time, seed germination, and biomass distribution and accumulation according to Sahoo et al. (2021) and Atta et al. (2023).

claimLight enhances the photosynthetic activity of plants, maximizes light energy absorption, and affects their response to photosynthetic regulation and environmental stresses, according to Malekzadeh et al. (2024).

referenceDifferent spectral bandwidths of light have genotype-specific modulatory effects on the nutritive and phytochemical composition of microgreens.

claimLight is the most significant external environmental condition affecting plant growth and development compared to temperature, gravity, water, and minerals.

claimLight induces morphological changes in the packaging of anthocyanins, the distribution of vacuole compartments and subvesicular compartments, and the diffusion of anthocyanins from inclusions into the vacuole sap, allowing vacuoles containing anthocyanins to fuse, as reported by Irani and Grotewold (2005).

claimLight regulates the process of sugar metabolism in plants, which helps to improve growth, development, adaptability, and resistance to environmental stresses.

claimLight regulates plant sugar content by affecting the enzymes involved in sugar metabolism, which are the basic substances produced by photosynthesis.

claimPlants integrate light and temperature signals to adapt to cold environments, as revealed by Wang et al. (2020).

referenceSingle-cell RNA sequencing (scRNA-seq) of Arachis hypogaea L. seedling leaves reveals distinct gene expression atlases induced by light and dark conditions.

claimLight serves as the basic energy source for photosynthesis and influences plant energy production and material synthesis.

claimLight acts as a material energy source for plants, supporting processes such as cell division, cell differentiation, chlorophyll synthesis, tissue growth, and stomatal movement.

claimLight regulates plant growth and development throughout the life cycle by directly influencing physiological processes through photosynthesis and photomorphogenesis, as established by Gálvez et al. (2020) and Deng et al. (2024).

claimLight provides the energy necessary for plant photosynthesis, which enables plants to produce organic matter and perform energy conversion during growth and development.

claimYoshida S., Mandel T., and Kuhlemeier C. (2011) demonstrated that stem cell activation by light guides plant organogenesis.

referenceSpaninks and Offringa (2023) demonstrated that local phytochrome signaling limits root growth in light by repressing auxin biosynthesis.

claimUnder abiotic stress, plants respond to environmental changes by sensing light to prevent cell or tissue damage, and light regulates plant hormones such as jasmonic acid, salicylic acid, and ethylene to increase resistance to pests and microbes according to Li et al. (2024a).

claimLight serves as the final energy source for green plant metabolism, according to Wei et al. (2023).

claimLight influences plant sugar metabolism through photosynthesis, sugar signaling, and photoperiodic regulation, with different light conditions inducing changes in plant metabolites.

referenceBao et al. (2024) reviewed how light and light signals regulate growth and development in woody plants.

claimLight regulates plant growth, development, and reproduction, and influences the formation of meristematic tissues into lateral organs through the regulation of growth hormones and cytokinins, according to Yoshida et al. (2011).

referenceThe review article titled 'The role of light in regulating plant growth, development and sugar metabolism: a review' was published in Frontiers in Plant Science on January 7, 2025, by authors Wu W, Chen L, Liang R, Huang S, Li X, Huang B, Luo H, Zhang M, Wang X, and Zhu H.

procedureDuring plant photosynthesis, chloroplasts absorb light energy to generate sucrose; this sucrose is catalyzed by invertase (INV) in the vacuole to generate glucose, which is then catalyzed by sucrose synthase (SUS) in the mitochondria to generate UDP-glucose, which is subsequently acted upon by UGPase in the cell nucleus and converted into polysaccharides by glycosyltransferases (GTs), with light participating to ensure energy supply for these processes.

claimLight functions as a signal that influences plant cell division and differentiation by activating photoreceptors and signal transduction pathways, which subsequently alters hormone levels and impacts developmental, physiological, and morphological processes, according to Deepika et al. (2020), Bao et al. (2024), and Hernandez-Castellano et al. (2024).

claimSeed source, light, and nitrogen levels affect biomass and nutrient allocation patterns in seedlings of Pongamia pinnata.

claimLight inhibits cell wall deposition by affecting the accumulation of cellulose, hemicellulose, and pectin, which alters cell wall plasticity, growth, and mechanical properties in shoot tissues, while increasing cell wall thickness and cellulose content, according to Brüggenwirth and Knoche (2017) and Xu et al. (2024b).
