“…In addition, bi-weekly application of 25 and 100 mg/L caused a significant decrease (5-fold) in antioxidant activity compared to control (Fc ¼ 1578.18; df ¼ 6; p-value ¼ 0.0002) (Figure 6). Given these findings, it is clear that both SBA-15 and SBA-16 at the evaluated doses elicited plant defense pathways, aligning with several published reports demonstrating controlled stress induction as an elicitation strategy for plant performance improvement (V azquez-Hern andez et al, 2019b;Parola-Contreras et al, 2020). Select SBA treatments evaluated in the present study clearly caused controlled elicitation in chili pepper based on demonstrated increases in immunity indicators such as phenylpropanoids and antioxidant activity.…”

“…However, the production of natural pathways by plants is low and it depends on different features such as the physiological and developmental stage of the plant [11]. Additionally, a strategy for incrementally increasing the production of these compounds is plant elicitation [12,13].…”

Bioactive compounds (e.g., flavonoids, phenolics acids, alkaloids and carotenoids) are commercially-valued products, due to their wide array of applications in the medical, pharmacological, cosmetic, agriculture and food industry. A strategy applied to increase or enhancing bioactive compounds production in plants is controlled elicitation. In recent years, many researchers have studied the role of nanoparticles (NPs) as a novel elicitor for the biosynthesis of bioactive compounds shown that the NPs could affect the plant’s secondary metabolism in plant and culture systems. In this sense, recent studies have highlighted the potential applications of nanotechnology in crop production by improving the nutraceutical and nutritional quality of plants. In this review, we present studies about the application of NPs to enhance the production of bioactive plant metabolites. The aforementioned studies in ex vitro as in vitro, in addition to the effect of post-harvest by NPs application.

“…Many elicitor treatments have been linked with reactive oxygen species (ROS) over-accumulation, especially hydrogen peroxide (H 2 O 2 ), leading to an oxidative stress that directly activates secondary metabolite formation [22,[26][27][28]. Plant responses to H 2 O 2 are of great interest due to the role of H 2 O 2 as a signaling molecule, being perceived as an elicitor that, when added exogenously, may trigger an oxidative stress leading to secondary metabolites accumulation [29][30][31][32]. Plants have an antioxidant defense system composed of enzymatic and non-enzymatic components [33].…”

Hairy roots (HRs) grown in vitro are a powerful platform for plant biotechnological advances and for the bio-based production of metabolites of interest. In this work, black carrot HRs able to accumulate anthocyanin as major secondary metabolite were used. Biomass and anthocyanin accumulation were improved by modulating growth medium composition—different Murashige & Skoog (MS)-based media—and H2O2-elicitation, and the level of the main antioxidant enzymes on elicited HRs was measured. Higher growth was obtained on liquid 1/2 MS medium supplemented with 60 g/L sucrose for HRs grown over 20 days. In this medium, 200 µM H2O2 applied on day 12 induced anthocyanin accumulation by 20%. The activity of superoxide dismutase (SOD)—which generates H2O2 from O2•−—increased by over 50%, whereas the activity of H2O2-scavenging enzymes was not enhanced. Elicitation in the HRs can result in a controlled oxidative burst, in which SOD activity increased H2O2 levels, whereas anthocyanins, as effective reactive oxygen species scavengers, could be induced to modulate the oxidative burst generated. Moreover, given the proven stability of the HR lines used and their remarkable productivity, this system appears as suitable for elucidating the interplay between antioxidant and secondary metabolism.
