Plasticity of photosynthetic processes and the accumulation of secondary metabolites in plants in response to monochromatic light environments: A review
TL;DR: Overall, blue light may promote the accumulation of phenylpropanoid-based compounds without substantially affecting plant morpho-anatomical traits compared to the effects of white light, while red light, conversely, strongly alters plant morphology and physiology compared to that under white light without showing a consistent positive effect on secondary metabolism.

TL;DR: Microgreen enrichment of carotenoid and xanthophyll pigments may be achieved using higher (16-33%) blue light intensities and significant quantitative changes in response to blue light percentage were obtained for both directly and not directly light-dependent metabolite groups.

Polyphenols: food sources and bioavailability
TL;DR: The nature and contents of the various polyphenols present in food sources and the influence of agricultural practices and industrial processes are reviewed, and bioavailability appears to differ greatly between the variousPolyphenols, and the most abundantpolyphenols in the authors' diet are not necessarily those that have the best bioavailability profile.

Effects of supplemental light quality on growth and phytochemicals of baby leaf lettuce
Qian Li,Qian Li,Chieri Kubota +2 more
TL;DR: The results demonstrated that supplemental light quality could be strategically used to enhance nutritional value and growth of baby leaf lettuce grown under white light.

Blue Light-emitting Diode Light Irradiation of Seedlings Improves Seedling Quality and Growth after Transplanting in Red Leaf Lettuce
TL;DR: It is indicated that raising seedlings treated with blue light promoted the growth of lettuce plants after transplanting, likely because of high shoot and root biomasses, a high content of photosynthetic pigments, and high antioxidant activities in the lettuce seedlings before transplanting.
