“…Beneficial elements cause growth retardation, enzymatic activity changes (Gopal and Rizvi, 2008) and photosynthesis disorders (Ganesh et al, 2008). Beneficial elements are used to increase SMs; for example, the content of α-tocopherol, asparagine and tyrosine (Hédiji et al, 2010), isocitrate dehydrogenase (ICDH), citrate synthase (CS), fumarase, malate dehydrogenase (MDH) and phosphoenolpyruvate carboxylase (PEPC) increases in tomato plants (López-Millán et al, 2009) when 100 µM Cd is used in the NS.…”

Plants are essential sources of bioactive substances that promote health. For economic reasons, farmers usually focus on obtaining higher yields rather than crop nutraceutical quality. The application of non-essential elements (NEEs) is a technique used to increase secondary metabolites (SMs) in plants. This technique includes variations of the essential elements ratios in a nutrient solution or the inclusion of elicitors, such as salicylic acid or methyl jasmonate. Elicitor use is controversial because plants grow differently in inert substrates, in vitro and soil. Soil contains essential elements (EEs) and NEEs that can enhance SM synthesis and increase nutraceutical plant quality. However, any technique that modifies plant metabolism can decrease yields. Thus, developing techniques to increase both agricultural product yield and quality is necessary. This review aims to demonstrate the necessity for a new recipe or "cocktail" of plant nutrients based on EEs and NEEs, and elicitors apply to achieve both a high yield and crops nutraceutical quality.

“…Heavy metals such as cadmium (Cd) and chromium (Cr) induce enzyme inhibition, cellular oxidation, and the alteration of the metabolism [4]. Cr(VI) is the most toxic oxidation state of chromium, and its uptake is shown to influence the concentration of numerous primary and secondary metabolites [5].…”

Metabolomic analysis of wild and transgenic Nicotiana langsdorffii plants exposed to abiotic stresses: unraveling metabolic responses

et al. 2015

Nicotiana langsdorffii plants, wild and transgenic for the Agrobacterium rhizogenes rol C gene and the rat glucocorticoid receptor (GR) gene, were exposed to different abiotic stresses (high temperature, water deficit, and high chromium concentrations). An untargeted metabolomic analysis was carried out in order to investigate the metabolic effects of the inserted genes in response to the applied stresses and to obtain a comprehensive profiling of metabolites induced during abiotic stresses. High-performance liquid chromatography separation (HPLC) coupled to high-resolution mass spectrometry (HRMS) enabled the identification of more than 200 metabolites, and statistical analysis highlighted the most relevant compounds for each plant treatment. The plants exposed to heat stress showed a unique set of induced secondary metabolites, some of which were known while others were not previously reported for this kind of stress; significant changes were observed especially in lipid composition. The role of trichome, as a protection against heat stress, is here suggested by the induction of both acylsugars and glykoalkaloids. Water deficit and Cr(VI) stresses resulted mainly in enhanced antioxidant (HCAs, polyamine) levels and in the damage of lipids, probably as a consequence of reactive oxygen species (ROS) production. Moreover, the ability of rol C expression to prevent oxidative burst was confirmed. The results highlighted a clear influence of GR modification on plant stress response, especially to water deficiency-a phenomenon whose applications should be further investigated. This study provides new insights into the field of system biology and demonstrates the importance of metabolomics in the study of plant functioning.
