“…Down-regulation of the SOS2 gene by both salinity levels in our study is similar to its expression in Brassica oleracea, which demonstrated down-regulation of SOS2 gene expression in shoot tissue (Kumar et al, 2009). NCED3 gene expression was also induced in response to three different AgNP sizes and shapes (Syu et al, 2014). Plant adaptations to salinity are of three distinct types: osmotic stress tolerance, Na + or Cl − exclusion, and the tolerance of tissue to accumulated Na+ or Cl− (Munns and Tester, 2008).…”

To cite this paper: Almutairi, Z.M., 2016. Influence of silver nano-particles on the salt resistance of tomato (Solanum lycopersicum) during germination. AbstractSilver nanoparticles (AgNPs) have been implicated to enhance seed germination and plant growth, improve photosynthetic quantum efficiency and act as antimicrobial agents to manage plant diseases. The role of nanoparticles in the improvement of plant tolerance to environmental stresses such as drought and salinity remains unclear. In this study, we examined the effects of AgNP dose on the salt tolerance of tomato (Solanum lycopersicum L.) plants during germination. Tomato seeds were treated with different AgNP doses and germinated under salinity stress. Five concentrations of AgNPs (0.05, 0.5, 1.5, 2 and 2.5 mg L -1 ) and two levels of NaCl (150 and 100 mM) were tested. Seed germination and seedling growth of tomato plants were markedly inhibited by salt stress, and this effect was alleviated by exposure to AgNPs. The germination percentage, germination rate, root length and seedling fresh and dry weight of tomato were improved after exposure to AgNPs under NaCl stress. The expression of salt stress genes was investigated by semi-quantitative RT-PCR. Of the examined salt stress genes, four genes, AREB, MAPK2, P5CS and CRK1, were up-regulated by AgNPs under salt stress, and three genes, TAS14, DDF2 and ZFHD1, were down-regulated in response to AgNPs. The gene expression patterns associated with AgNP exposure also suggest the potential involvement of AgNPs in response to stress, indicating that they might be useful for improving plant tolerance to salinity.

“…Xiang et.al found that ZnO hexagonal nanorod and ZnO nanocolumniation showed different bio-effect to Chinese cabbage seeds [16]. Different morphologies may affect dissolution, uptake, stability of nanomaterials [15], result into gene expression alteration [17], further affect plants growth. Our study demonstrated that Fe 2 O 3 long nanorods had higher toxicity on germination than Fe 2 O 3 nanocubes and Fe 2 O 3 short nanorods, but the machanism need to be further investigated.…”

“…However, there was no obvious discrepancy in the MDA level among control, 25 nm CeO 2 and its bulk counterpart treatment. Other reports have studied the effects of size and shape of NPs on various plant species as well (Hawthorne et al 2012;Syu et al 2014). In addition, demonstrated that plant responses to CeO 2 exposure varied with particle sizes and the growth stages of plants.…”

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.
