“…Whereas, dehydroascorbate reductase (DHAR) and monodehydroascorbate reductase (MDAR) enzymes that regulate the cellular Asc redox state were downregulated (Fu et al, 2014). Proteomic analysis of AgNPs treated O. sativa roots revealed an increased abundance of SOD, APX, and glutathione- S -transferase (GST) (Mirzajani et al, 2014). These NPs also stimulated the activities of SOD and APX significantly, while inhibiting glutathione reductase (GR) and DHAR in Pisum sativum L. seedlings (Tripathi et al, 2017).…”

“…Recognition of AgNPs by plasma membrane bound receptors triggered a Ca 2+ burst and ROS induction in A. thaliana (Sosan et al, 2016). Ca 2+ levels and associated signaling pathway proteins were found to be upregulated in the proteomic analysis of AgNP treated O. sativa roots (Mirzajani et al, 2014). These authors hypothesized that AgNPs, or ions released thereof, impede cell metabolism by binding to Ca 2+ receptors, Ca 2+ channels, and Ca 2+ /Na + ATPases.…”

“…Although the accumulation of NPs in chloroplasts and damage to the photosynthetic apparatus (Da Costa and Sharma, 2016; Jiang et al, 2017) supports the former, the fact that to reach the chloroplast NPs must cross the plasma membrane, where they can induce reactive oxygen species (ROS) via NADPH oxidases (Sosan et al, 2016) argues the reverse. 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).…”

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.

“…It was found that 10 mg/L Ag NPs caused the alteration of all sorts of proteins which are vastly related to cell metabolism (Vannini et al 2014). Likewise, according to Mirzajani et al (2014), exposure of Oryza sativa L. to Ag NPs led to the identification of 28 responsive proteins, for example, decrement/increment in abundance, which were involved in various important physiological and biochemical processes, for example, Ca 2+ regulation and signaling, oxidative stress tolerance, cell wall and RNA/DNA/protein direct damage, transcription and protein degradation, ultimately leading to cell division and apoptosis. Hossain et al (2016) evaluated the phytotoxicity of Al 2 O 3 , ZnO and Ag NPs in soybean seedlings at the proteome level; 16 common proteins in soybean leaves were significantly changed, which were predominantly associated with protein degradation and photosystem.…”

With the rapid development of nanotechnology, the potential releases of nanoparticles (NPs) have drawn considerable attention. Plants are essential fundamental components of all ecosystems, and the interaction between NPs and plants is an indispensable aspect of the risk assessment. Originally, this review focuses on NP phytotoxicity, which is an important precondition to promote the application of nanotechnology and to avoid the potential ecological risks. Both enhancive and inhibitive effects of various NPs on different plants' growth have been documented. In this paper, the influence factors of nanotoxicity and the mechanisms of these toxic effects are also summarized. Subsequently, the defense mechanisms are presented as well. Eventually, this review puts forward the prospects of research direction of the environmental behavior and the biological toxicity of NPs, hoping to bring new ideas to the further research on NP phytotoxicity.

“…The transcriptional response of Arabidopsis plants exposed to Ag NPs was analyzed using whole-genome cDNA expression microarrays [55] which result in upregulation of 286 genes, including the genes primarily associated with metal and oxidative stress (e.g., vacuolar cation/proton exchanger, superoxide dismutase, cytochrome P450-dependent oxidase, and peroxidase), and down regulation of 81 genes, including the genes involved in plant defense system and hormonal stimuli (e.g., auxin-regulated gene involved in organ size-ARGOS, ethylene signaling pathway, and SAR against pathogens). On the other hand, the effects of silver nanoparticles on proteomic study of rice that reveals silver nanoparticles responsive proteins were primarily associated with oxidative stress response pathway, Ca 2+ regulation and signaling, transcription, protein degradation, cell wall synthesis, cell division, and apoptosis [56]. The effect of zinc oxide (nZnO) in Arabidopsis thaliana [57], fullerene soot (FS) or titanium dioxide (nTiO 2 ) nanoparticles on gene expression in roots and resulted in 660 up-and 826 down-regulated genes, 232 up-and 189 downregulated genes, and 80 up-and 74 down-regulated genes, respectively (expression difference > 2-fold).…”

Abiotic and Biotic Stress in Plants

The response of plants to abiotic stress is complex and involves changes in their morphology, physiology and metabolism. A number of strategies are being followed to enhance the tolerance of abiotic stress conditions, including the development of genetically-engineered varieties containing various gene constructs believed to enhance the performance under stress conditions. Nanotechnology is a versatile field and has found application in almost all the existing fields of science. The application of nanoparticles increased germination and seedling growth, physiological activities including photosynthesis and nitrogen metabolism, leaf activities of CAT, POX and APX, chlorophyll contents, protein, carbohydrate contents and yield, and also positive changes in gene expression indicating their potential use in crop improvement. Nanoparticles enhances the water stress tolerance via enhancing root hydraulic conductance and water uptake in plants and showing differential abundance of proteins involved in oxidation-reduction, ROS detoxification, stress signaling, and hormonal pathways. The mobility of the nanoparticles is very high, which leads to rapid transport of the nutrient to all parts of the plant. In particular, the most actual is to find ways to increase the adaptation potential of cultivated plants with the use of nanopreparations in stressful conditions.
