“…(Yin et al, 2012; Syu et al, 2014; Goswami et al, 2017), in addition to other, yet unknown, parameters. Although a recent study showed that ecologically relevant size and concentration of CdONPs could activate secondary metabolism in barley plants (Večeřová et al, 2016), it is difficult to generalize the impact of NPs on plant secondary metabolism in the environmental perspective. However, it is necessary to improve our understanding on the environmental fate of NPs and their hazards/risks, testing ecologically relevant conditions and concentrations in the context of plant secondary metabolism.…”

“…A substantial increase in plant growth and diosgenin concentration was observed in fenugreek after 2 μg/kg AgNP treatment (Jasim et al, 2017). Ferulic acid and isovitexin were increased in barley plants exposed to CdO (cadmium oxide) NPs in air for 3 weeks at a concentration of 2.03 ± 0.45 × 10 5 particles cm -3 (Večeřová et al, 2016). In A. thaliana , anthocyanin and flavonoid biosynthetic genes were upregulated in response to AgNPs (Garcia-Sanchez et al, 2015).…”

“…ROS production, damage to the membrane structure and function, and fluctuation in antioxidant enzymatic activities are documented across plant species as common responses to NPs (Thwala et al, 2013; Vannini et al, 2013; Fu et al, 2014; Mirzajani et al, 2014; Hossain et al, 2015; Xia et al, 2015; Jiang et al, 2017; Tripathi et al, 2017). A few studies have also demonstrated that treatment of plants and photosynthetic microorganisms with NPs resulted in increased production of phenolics (Comotto et al, 2014; Ghorbanpour and Hadian, 2015; Večeřová et al, 2016), which might act as antioxidants to scavenge the ROS (Dixon and Paiva, 1995; Franklin et al, 2009). …”

Nanoparticles Alter Secondary Metabolism in Plants via ROS Burst

The particles within the size range of 1 and 100 nm are known as nanoparticles (NPs). NP-containing wastes released from household, industrial and medical products are emerging as a new threat to the environment. Plants, being fixed to the two major environmental sinks where NPs accumulate — namely water and soil, cannot escape the impact of nanopollution. Recent studies have shown that plant growth, development and physiology are significantly affected by NPs. But, the effect of NPs on plant secondary metabolism is still obscure. The induction of reactive oxygen species (ROS) following interactions with NPs has been observed consistently across plant species. Taking into account the existing link between ROS and secondary signaling messengers that lead to transcriptional regulation of secondary metabolism, in this perspective we put forward the argument that ROS induced in plants upon their interaction with NPs will likely interfere with plant secondary metabolism. As plant secondary metabolites play vital roles in plant performance, communication, and adaptation, a comprehensive understanding of plant secondary metabolism in response to NPs is an utmost priority.

“…The over-expression of PAL (a defense gene) leads to the enhanced production of PC [46]. Several studies have demonstrated that treatments of plants with cadmium oxide NPs or CuO NPs produce an increase in PC, which could act as an antioxidant to scavenge ROS [47,48]. ROS may act as a normal signal for adaptation to Cu stress and could induce the accumulation of TPC in lentil roots [49].…”

Impact of Copper Oxide Nanoparticles on Enhancement of Bioactive Compounds Using Cell Suspension Cultures of Gymnema sylvestre (Retz.) R. Br

et al. 2019

Gymnema sylvestre is a plant that is enriched in bioactive compounds. In particular, gymnemic acids (GA) and phenolic compounds (PC) are pharmaceutically important. There is a commercial demand for naturally occurring bioactive compounds, but their availability is limited due to geographical and seasonal variations. The elicitation approach can enhance the biosynthesis of phytochemicals during in vitro culture of G. sylvestre. Here, to further improve gymnemic acid II (GA II) and phenolic compounds (PC) production by G. sylvestre, cell suspension cultures (CSC), which has attracted attention for the production of essential phytochemicals, was explored using copper oxide nanoparticles (CuO NPs). Callus was obtained on MS medium containing 2,4-dichlorophenoxyacetic acid, kinetin, phytoagar, and sucrose. Agar-free MS medium was used to initiate CSC, which was treated with three concentrations of CuO NPs (1, 3 or 5 mg/L). Treatment for 48 h with 3 mg/L CuO NPs resulted in the greatest yields of GA II, total phenolics, and flavonoids. The cultures also displayed pronounced antioxidant, antidiabetic, anti-inflammatory, antibacterial, antifungal, and anticancer activities. The use of CuO NPs (3 mg/L) significantly increased the production of GA II (nine-fold) and PC compared to unamended CSC. We propose that CSC and use of nanoparticles (NPs) as a new generation of elicitors, offer a suitable prospect for the production of bioactive compounds.

“…Vecerova et al have showed that cadmium nanoparticles (CdO) significantly affected the total content of primary plant metabolites (amino acids and sugars) without a substantial impact on the total content of the secondary metabolites (phenolic compounds, Krebs cycle acids, and fatty acids) but changed the content of the saturated and unsaturated fatty acids in the roots and leaves of treated plants [22]. …”

The Effect of Silver and Copper Nanoparticles on the Wheat—Pseudocercosporella herpotrichoides Pathosystem

et al. 2017

The paper covers the study of the effects of silver (Ag) and copper (Cu) nanoparticles on wheat—Pseudocercosporella herpotrichoides pathosystem in general and, separately, on their interaction both with the plant and with the pathogen. Plants, treated with nonionic colloidal solutions of biogenic metal nanoparticles of Ag and Cu, have taken seed treatment as stress and have demonstrated the same changes in the dynamic patterns of thiobarbituric acid reactive substances (TBARS) content as a seedling infection or in its combination with a nanoparticle treatment. The wheat variety, which is sensitive to pathogen action, has showed a substantial (100%) increase in the TBARS contents, while the other varieties has shown lesser (40%) changes in the TBARS content as compared to the control. Besides, both silver and copper nanoparticles have not affected the growth and development of P. herpotrichoides, thus suggesting that the effect of nanoparticles is determined by the plant’s responses to the pathogen rather than the phytotoxic action of the copper or silver nanoparticles, at least during the initial stages of the pathological process.
