“…Plant foods are a source of vitamins and minerals but also a notable source of health‐promoting phytochemicals, called plant secondary metabolites (PSM), which are organic small biomolecules derived from primary metabolites. They partake in various physiological activities and have a crucial role in plant defense and plant‐environment interaction . Plant secondary metabolites are often signature components of certain plant species or genera and play a major role in plant stress and defense responses or in central and secondary metabolism .…”

“…These latters present in plant‐rich diets, affect positively human health and decrease mortality by preventing a range of common diseases like macular degeneration, cancer, and cardiovascular diseases . Plant secondary metabolites are also considered biosynthetic end products, able to accumulate in plants at high levels, unlike primary metabolites, and are of major benefit to humans as active medicinal ingredients . In fact, many antibiotics, anti‐tumor agents, and antivirals are derivates of PSMs, as are many food additives and some herbicides and phyto‐toxins used in agriculture …”

BACKGROUND Through precise control of the nutrient solution (NS), closed soilless systems enable targeted manipulation of plant secondary metabolites, which constitute health‐promoting components of the human daily diet. A nutrient film technique (NFT) system was employed to assess the effect of NS macronutrient‐based concentration (full, half‐, and quarter‐strength corresponding to electrical conductivity (EC) of 1.5, 0.75, and 0.5 dS m−1) on the bioactive profile of red and green‐pigmented Salanova® butterhead lettuce. RESULTS Half‐strength NS reduced fresh biomass of both cultivars by 14%, whereas quarter‐strength NS reduced the fresh biomass of green and red Salanova by 24% and 38%, respectively. However, moderate nutrient stress (half‐strength NS) boosted red Salanova total ascorbic acid, chlorogenic, chicoric, caffeoyl‐meso‐tartaric, total phenolic acids, and anthocyanins concentrations by 266%, 199%, 124%, 251%, 162%, and 380%, respectively compared with the control, full‐strength NS. CONCLUSIONS Nutritional eustress and appropriate cultivar selection are effective means to increase phytochemical content and optimize year‐round production of lettuce in closed soilless systems. © 2019 Society of Chemical Industry

“…A great diversity in the types of microbial, physical, or chemical factors, known as elicitors, could influence the levels of secondary metabolites in plants (Zhao et al, 2005; Vasconsuelo and Boland, 2007; Jimenez-Garcia et al, 2013; Verma and Shukla, 2015). For example, the elicitors such as nutrient supply, temperature, metal ions, light conditions and atmospheric CO 2 concentrations affect the production of secondary metabolites in plants (Nascimento and Fett-Neto, 2010; Gandhi et al, 2015).…”

“…For example, the elicitors such as nutrient supply, temperature, metal ions, light conditions and atmospheric CO 2 concentrations affect the production of secondary metabolites in plants (Nascimento and Fett-Neto, 2010; Gandhi et al, 2015). The elicitors derived from bacteria, fungi, viral pathogens and even plants also contribute to the variability in plant secondary metabolism (Berenbaum, 1995; Verma and Shukla, 2015). Previously, we showed that exogenous methyl jasmonate (MeJA) application accelerated the Amaryllidaceae alkaloids accumulation in Lycoris chinensis seedlings (Mu et al, 2009).…”

Lycoris aurea, a medicinal species of the Amaryllidaceae family, is used in the practice of traditional Chinese medicine (TCM) because of its broad pharmacological activities of Amaryllidaceae alkaloids. Despite the officinal and economic importance of Lycoris species, the secondary mechanism for this species is relatively deficient. In this study, we attempted to characterize the transcriptome profiling of L. aurea seedlings with the methyl jasmonate (MeJA) treatment to uncover the molecular mechanisms regulating plant secondary metabolite pathway. By using short reads sequencing technology (Illumina), two sequencing cDNA libraries prepared from control (Con) and 100 μM MeJA-treated (MJ100) samples were sequenced. A total of 26,809,842 and 25,874,478 clean reads in the Con and MJ100 libraries, respectively, were obtained and assembled into 59,643 unigenes. Among them, 41,585 (69.72%) unigenes were annotated by basic local alignment search tool similarity searches against public sequence databases. These included 55 Gene Ontology (GO) terms, 128 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, and 25 Clusters of Orthologous Groups (COG) families. Additionally, 4,175 differentially expressed genes (DEGs; false discovery rate ≤ 0.001 and |log2 Ratio| ≥ 1) with 2,291 up-regulated and 1,884 down-regulated, were found to be affected significantly under MeJA treatment. Subsequently, the DEGs encoding key enzymes involving in the secondary metabolite biosynthetic pathways, transcription factors, and transporter proteins were also analyzed and summarized. Meanwhile, we confirmed the altered expression levels of the unigenes that encode transporters and transcription factors using quantitative real-time PCR (qRT-PCR). With this transcriptome sequencing, future genetic and genomics studies related to the molecular mechanisms associated with the chemical composition of L. aurea may be improved. Additionally, the genes involved in the enrichment of secondary metabolite biosynthesis-related pathways could enhance the potential applications of L. aurea.
