“…The lowest value was found in IR-FL plants perhaps because IR may have induced the proteins’ degradation or inhibited their synthesis [ 51 , 52 ]. Conversely, IR-FS and IR-RB plants showed a greater protein content likely due to the positive effect exerted by blue and red wavelengths on the protein synthesis [ 32 , 53 , 54 , 55 ]. It is also reasonable to assume that the increase in Rubisco amount significantly contributed to the total protein rise under these treatments.…”

This study evaluated if specific light quality (LQ) regimes (white fluorescent, FL; full-spectrum, FS; red-blue, RB) during plant growth modified morphological and photosynthetic traits of Solanum lycopersicum L. ‘Microtom’ plants irradiated at the dry seed stage with 25 Gy 48Ca ions (IR). The irradiation reduced plant size while it increased leaf dry matter content (LDMC) and relative water content (RWC) compared to the control. FS and RB light regimes determined a decrease of plant height and a rise of RWC compared to FL plants. The irradiation under FS and RB regimes favoured the development of dwarf plants and improved the leaf water status. Under the FL regime, irradiated plants showed reduced photosynthesis and stomatal conductance. The opposite behavior was observed in RB irradiated plants in which gas exchanges were significantly stimulated. RB regime enhanced Rubisco expression in irradiated plants also inducing anatomical and functional adjustments (i.e., increase of leaf thickness and incidence of intercellular spaces). Finally, 48Ca ions did not prevent fruit ripening and the achievement of the ‘seed-to seed’ cycle, irrespective of the LQ regime. Overall, the present study evidenced that RB light regime was the most effective in optimising growth and photosynthetic efficiency of ‘Microtom’ irradiated plants. These outcomes may help to develop proper cultivation protocols for the growth of dwarf tomato in Controlled Ecological Life Support Systems (CELSS).

“…Furthermore, the open field cultures are increasingly threatened by the risks and uncertainties associated with biotic and abiotic stresses, such as pest attacks, drought, and frost, exacerbated by the ongoing climate change ( Pandey et al, 2017 ), compelling need for new cultivation approaches ( Dutta-Gupta, 2017 ; FAO, 2019 ). The Controlled Environment Agriculture (CEA) has emerged as a feasible alternative, as it optimizes the plant growth environment by minimizing the interactions with the external factors ( Dutta-Gupta, 2017 ; Amitrano et al, 2018 ; Pennisi et al, 2019 ). The manipulation of light quality in CEA through light-emitting diodes (LEDs) technology modifies plant morphological, anatomical, and physiological traits ( Arena et al, 2016 ; Yang et al, 2017 ), allowing to select the more appropriate light regime to improve crop productivity and food quality for a specific crop.…”

Light quality plays an essential role in setting plant structural and functional traits, including antioxidant compounds. This paper aimed to assess how manipulating the light spectrum during growth may regulate the photosynthetic activity and fruit bioactive compound synthesis in Solanum lycopersicum L. cv. ‘Microtom’ to improve plant physiological performance and fruit nutritional value. Plants were cultivated under three light quality regimes: red-green-blue LEDs (RGB), red-blue LEDs (RB) and white fluorescent lamps (FL), from sowing to fruit ripening. Leaf functional traits, photosynthetic efficiency, Rubisco and D1 protein expression, and antioxidant production in fruits were analyzed. Compared to FL, RGB and RB regimes reduced height and increased leaf number and specific leaf area, enhancing plant dwarf growth. The RGB regime improved photosynthesis and stomatal conductance despite lower biomass, favoring Rubisco synthesis and carboxylation rate than RB and FL regimes. The RB light produced plants with fewer flowers and fruits with a lower ascorbic acid amount but the highest polyphenol content, antioxidant capacity and SOD and CAT activities. Our data indicate that the high percentage of the green wavelength in the RGB regime promoted photosynthesis and reduced plant reproductive capacity compared to FL and RB. Conversely, the RB regime was the best in favoring the production of health-promoting compounds in tomato berries.

“…Their consumption has been associated with a reduced risk of cancer, respiratory problems, osteoporosis, and muscle atrophy, which are frequent diseases associated with obesity and malnutrition [ 15 , 16 , 17 ]. Among these, Vigna radiata L. (mung bean) presents a high nutritional value of its sprouts, whose consumption has been related to antioxidant, anti-inflammatory, antidiabetic, antihypertensive, and antitumor effects [ 18 , 19 ]. Significant challenges in indoor agriculture, include the control of relative humidity (RH) and the demand for power supply, needed to artificially maintain a precise microclimate and especially light regimes to grow different plant species [ 20 , 21 , 22 ].…”

“…Even though lightening systems can increase production costs [ 21 ], changes during the early stages of germination lead to increments in some useful metabolites such as flavonoids, phenols, vitamins and other phytochemicals [ 30 , 31 ]. Many studies have tested the effect of light intensity and quality on sprout phytochemical content, with contrasting results depending on the PPFD (photosynthetic photon flux density) and on the specific wavelengths [ 18 , 32 , 33 ]. However, the general tendency is to have a higher quantity of antioxidants in light-grown sprouts compared to dark-grown ones [ 34 , 35 , 36 , 37 ], even if sprouts grown in the light can be smaller compared to those grown in the dark [ 38 ].…”

In the last decades, there has been a growing interest in the production of sprouts, since they are a highly nutritious food, particularly suitable for indoor farming in urban areas. Achieving sprout production in indoor systems requires an understanding of possible alterations induced by the microclimate. The aim of this study was to analyze the combined effect of presence/absence of light and high/low air relative humidity (RH) on mung bean sprouts. Morpho-anatomical development and functional anatomical traits in hypocotyl were quantified. The content of antioxidants, soluble sugars, and starch were measured for nutritional and functional purposes. Different RH regimes mainly induced morpho-anatomical modifications, while the presence/absence of light changed the content of antioxidant compounds. Increments in stele diameter at high RH suggest a higher water uptake and conductivity, compared to the low RH treatment; low RH and light induced anatomical traits improving plant water transport (reduced number of cortical layers) and increased the production of antioxidants. The overall results suggested that RH and light, already at the early stages of development, affect the plant’s nutritional value. Therefore, the combination of light and low RH allows the production of antioxidant-rich mung bean sprouts to be used as a food supplement.
