The role of light in regulating plant growth, development and sugar ... frontiersin.org Jan 6, 2025 5 facts
referenceThe dark reaction of photosynthesis takes place in the stroma of the chloroplasts and utilizes ATP and NADPH produced by the light reaction to convert carbon dioxide to organic matter and produce glucose through energy conversion; subsequently, enzymes facilitate the formation of other sugars to provide material and energy for plant growth and development.
claimDecreasing light intensity causes the structure of chloroplasts and mitochondria to degrade or be destroyed, which negatively affects the metabolism of material and energy in plants.
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).
claimChloroplasts absorb light energy via chlorophyll and other pigments to drive the photochemical reactions of photosynthesis.
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.

claimConductance to carbon dioxide (gCO2) is a composite term representing the rate of diffusion through stomata, the rate of diffusion across intercellular air spaces into chloroplasts, and the rate of enzymatic carbon fixation.
claimIn C4 plants, mesophyll cells contain PEP carboxylase and few chloroplasts, while bundle sheath cells, which surround the xylem and phloem, contain rubisco and many chloroplasts.
