“…Moreover, 111 genes were unique for AgNPs, and they were enriched for three biological functions: response to fungal infection, anion transport, and cell wall/plasma membrane related (Kohan-Baghkheirati and Geisler-Lee, 2015). The expression patterns of genes investigated in this study suggest that they are regulated in response to AgNPs, which represents a novel abiotic stressor for plants (Geisler-Lee et al, 2013;Qian et al, 2013).…”

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.

“…Our previous study with Arabidopsis also indicated that there is a size limitation on the potential uptake and accumulation of AgNPs. In that study, we found that only AgNPs smaller than 40 nm were successfully internalized in Arabidopsis root cells and some appeared to reach the vascular tissues for possible transport to the shoots (Geisler- Lee et al 2013). Haverkamp and Marshall (2009) also investigated the uptake of Ag ion complexes and AgNPs by Brassica juncea plants.…”

Rapidly expanding world population and dwindling arable land around the world demand innovative technologies to drastically enhance the global crop yield in the near future. The advancement in nanotechnology provides some possibility to achieve this goal. However, the application of nanomaterialcontaining fertilizers and other agricultural products also carries environmental and health risks such as the accumulation of nanomaterial residues in edible tissues, which leads to potential phytotoxicity to agricultural crops and disturbance to the ecosystem. These environmental and health risks need to be well understood before the application of nanotechnology in agriculture can be fully embraced. This chapter presents a summary on the available information concerning the uptake, transport, and accumulation of engineered nanomaterials (ENMs) by agricultural crops and their potential toxicity to these crops. This chapter also discusses the modifications of the fate and transport of coexisting environmental chemicals by ENMs and potential correlations between the unique properties of ENMs with their fate and impact in agricultural systems to shed light on further beneficial applications of ENMs in agriculture.

“…In general, the toxicity of metal ions significantly exceeds the toxicity of nanoparticles [85], and the phytotoxic effect of Ag NPs is higher than that of Au NPs [86]. The toxic effect was manifested in inhibition of elongation of the arabidopsis roots, an increase in the vegetation period by 2-3 days, a decrease in seed germination rate in the offspring, and, according to the authors, was due to the diffusion of silver ions from the Ag NP surface.…”

A b s t r a c tGold and silver nanoparticles are used in a variety of biomedical practice as carriers of drugs, enhancers and/or converters of optical signal, immunomarkers, etc. The review examines a decade publications (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) pertaining to the various influence of nanoparticles of noble metals (gold and silver) on growth and productivity of higher plants. In fact, possible phytotoxicity of these nanoparticles is being actively studied for over 10 years. The topicality of this field of research is due to the detection of a number of natural and human-caused factors resulting in interactions of plants with nanoparticles (B.P. Colman et al., 2013; N.G. Khlebtsov et al., 2011). A positive or negative impact of nanoparticles on plants is little known, and the information is very contradictory (P. Manchikanti et al., 2010; M. Carrière et al., 2012; C. Remédios et al., 2012; N. Zuverza-Mena et al., 2016). In the study both model (Arabidopsis thaliana) and cultivated plants (soy, canola, beans, rice, radish, tomato, pumpkin, etc.) were involved. The discussed data are indicative of both positive and negative effects of metal nanoparticles on plants, as well as of the chemical nature, size, shape, surface charge, and the dose introduced being the major factors that are responsible for the processes of intracellular nanoparticle penetration. In general terms, it was mentioned that silver nanoparticles were more toxic as compared to gold ones being due to more active silver ion diffusion from the silver nanoparticle surface. Silver ions are known to inhibit effectively biosynthesis of ethylene -a phytohormone controlling processes of plant stress, aging etc., wherein gold ions do not influence ethylene biosynthesis and signaling. Considered all, metal ion toxicity exceeds considerably a toxicity of nanoparticles. The mechanism of the nanoparticle phytotoxic action is often connected with accumulation of active oxygen species in plant tissues. The use of cell suspension cultures may be a promising approach to study plant-nanoparticles interaction (E. Planchet et al., 2015). The period during which these studies are conducted is still small for elucidating all aspects with regard to biosafety. Contradictory (often conflicting) information on the impact of nanoparticles, in our opinion, is a result of diverse experimental conditions used. It is noted that while being clearly incomplete and contradictory, the obtained data suggest that a coordinated research program is needed that would detect correlations between particle parameters, experimental design, and the observed biological effects.Keywords: gold nanoparticles, silver nanoparticles, toxicity, biological effects, plantsIn recent decades, both scientists and the world community have paid much attention to nanotechnology, based on the use of objects no larger than 100 nm in the synthesis, assembly and modification of substances, materials and structures with unusual (often unexpected) properties.
