“…The control of anthocyanin synthesis by light spectrum was shown in apple ( Malus domestica ) peel, where anthocyanin synthesis was increased by the UV range of sunlight through upregulation of the MdMYB10 transcription factor and key enzymes of anthocyanin biosynthesis: PAL, chalcone synthase (CHS), flavanone-3-hydroxylase (F3H), dihydroflavonol 4-reductase (DFR), and anthocyanidin synthase (ANS) [ 247 ]. Lettuce plants grown under a 3:1 ratio of RL to BL accumulated more anthocyanin, which was derived from the transcriptional regulation of the related biosynthesis genes [ 248 ].…”

Both light intensity and spectrum (280–800 nm) affect photosynthesis and, consequently, the formation of reactive oxygen species (ROS) during photosynthetic electron transport. ROS, together with antioxidants, determine the redox environment in tissues and cells, which in turn has a major role in the adjustment of metabolism to changes in environmental conditions. This process is very important since there are great spatial (latitude, altitude) and temporal (daily, seasonal) changes in light conditions which are accompanied by fluctuations in temperature, water supply, and biotic stresses. The blue and red spectral regimens are decisive in the regulation of metabolism because of the absorption maximums of chlorophylls and the sensitivity of photoreceptors. Based on recent publications, photoreceptor-controlled transcription factors such as ELONGATED HYPOCOTYL5 (HY5) and changes in the cellular redox environment may have a major role in the coordinated fine-tuning of metabolic processes during changes in light conditions. This review gives an overview of the current knowledge of the light-associated redox control of basic metabolic pathways (carbon, nitrogen, amino acid, sulphur, lipid, and nucleic acid metabolism), secondary metabolism (terpenoids, flavonoids, and alkaloids), and related molecular mechanisms. Light condition-related reprogramming of metabolism is the basis for proper growth and development of plants; therefore, its better understanding can contribute to more efficient crop production in the future.

“…The blue light exposed lettuce plants were significantly taller and intense red in color, whereas, red light exposure resulted in green coloured leaves with significantly higher number of leaves per plant compared to the other two counterparts 41 . The accumulation of red color due to the accumulation of anthocyanin in response to exposure to blue light has been reported in Arabidopsis 42 , tomato 43 , pear 44 , 45 , Brassica napus 46 , lettuce 47 , many plant species 48 – 52 . A broader time course analysis at various developmental stages of plants following different light exposure would help further understanding of gene regulation linked to pigment accumulation.…”

Lettuce (Lactuca sativa) is grown in various parts of the world for use as a leafy vegetable. Although the use of light-emitting diode (LED) in controlled plant production systems has been successfully used to enhance nutritional quality and plant growth efficiently, the molecular basis of lettuce’s response to varying light spectra is not studied. Using next-generation sequencing, we have analyzed the transcriptomes of leaf lettuce (Lactuca sativa var. ‘New Red Fire’) grown hydroponically in a modular agricultural production system under three different types of LED lighting: red, blue, and white light. Illumina HiSeq sequencing platform was used to generate paired-end sequence reads (58 Gb raw and 54 Gb clean data) of the transcriptome of lettuce leaves exposed to varying light spectra. The de novo assembled final transcriptome contained 74,096 transcripts. Around 53% and 39% of the assembled transcripts matched to the UniProt and RefSeq RNA sequences, respectively. The validation of the differentially expressed transcripts using RT-qPCR showed complete agreement with RNA-Seq data for 27 transcripts. A comparison of the blue versus red light treatments showed the highest number of significantly differentially expressed transcripts. Among the transcripts significantly up-regulated in blue-light-exposed leaves compared to white-light-exposed leaves, ~ 26% were involved in the ‘response to stress’. Among the transcripts significantly upregulated under red light compared to white light, ~ 6% were associated with ‘nucleosome assembly’ and other processes, such as ‘oxidation–reduction process’ and ‘response to water deprivation’ were significantly enriched. Thus, the result from the current study provides deeper insights into differential gene expression patterns and associated functional aspects under varying light qualities.

“…Crops rich in anthocyanins are more nutritious and have a positive effect on human health when included in the diet (53). Anthocyanin content in red cultivars of lettuce has been shown to increase in response to increased light intensity (38) and altered spectrum (37, 54). The increase in PAP1 expression provided a genomic and molecular basis for the increase in anthocyanin content seen in the lettuce FI.…”

Semi-transparent organic solar cells (ST-OSCs) offer new agrivoltaic opportunities to meet the growing demands for sustainable food production. The tailored absorption/transmission spectrum of ST-OSCs not only impacts the power generated, but also aspects of crop growth, development and responses to the biotic and abiotic environments. The general relationships between these variables are unknown. Here, we grow red oak leaf lettuce (Lactuca sativa), a traditional greenhouse crop, under three different ST-OSC filters and observe little overall differences on productivity in response to the altered light exposure. In contrast, several key traits involving nutrient content and nitrogen utilization as well as plant defense against herbivory and pathogens are modified over the controls under select OSCs. Overall, our genomic analysis reveals that lettuce production exhibits beneficial traits under exposure from select ST-OSCs. ST-OSCs integrated into greenhouses are, therefore, not only a promising technology for energy-neutral crop production as previously shown but can deliver benefits beyond those based on energy-balance considerations.
