“…The concentration of specialized metabolites can be improved by growing them in a controlled environment, resulting in lower costs for extraction of the active principles. Furthermore, their facilitated crop management and harvesting suggest a higher profit margin when cultivated in vertical farms 84,85 . Several studies revealed an association between the accumulation of specialized metabolites and artificial LED treatments in medicinal plants, although they showed different responses depending on species and experimental characteristics (Table S1 and Fig.…”

Specialized metabolites from plants are important for human health due to their antioxidant properties. Light is one of the main factors modulating the biosynthesis of specialized metabolites, determining the cascade response activated by photoreceptors and the consequent modulation of expressed genes and biosynthetic pathways. Recent developments in light emitting diode (LED) technology have enabled improvements in artificial light applications for horticulture. In particular, the possibility to select specific spectral light compositions, intensities and photoperiods has been associated with altered metabolite content in a variety of crops. This review aims to analyze the effects of indoor LED lighting recipes and management on the specialized metabolite content in different groups of crop plants (namely medicinal and aromatic plants, microgreens and edible flowers), focusing on the literature from the last 5 years. The literature collection produced a total of 40 papers, which were analyzed according to the effects of artificial LED lighting on the content of anthocyanins, carotenoids, phenols, tocopherols, glycosides, and terpenes, and ranked on a scale of 1 to 3. Most studies applied a combination of red and blue light (22%) or monochromatic blue (23%), with a 16 h day−1 photoperiod (78%) and an intensity greater than 200 μmol m−2 s−1 (77%). These treatment features were often the most efficient in enhancing specialized metabolite content, although large variations in performance were observed, according to the species considered and the compound analyzed. The review aims to provide valuable indications for the definition of the most promising spectral components toward the achievement of nutrient‐rich indoor‐grown products. © 2021 The Authors.
