“…Many aspects of 4-500 nm Fe NPs influence on plants were studied, but there is no prominent information about Fe 3 O 4 NPs genotoxicity in plants [34]. Therefore, the aim of present study was to detect the iron oxide NPs in flax cells and to investigate the impact of different concentrations of Fe 3 O 4 nanoparticles on explants and calluses of Linum usitatissimum L.…”

Development of nanotechnology leads to the increasing release of nanoparticles in the environment that results in accumulation of different NPs in living organisms including plants. This can lead to serious changes in plant cultures which leads to genotoxicity. The aims of the present study were to detect if iron oxide NPs pass through the flax cell wall, to compare callus morphology, and to estimate the genotoxicity in Linum usitatissimum L. callus cultures induced by different concentrations of Fe 3 O 4 nanoparticles. Two parallel experiments were performed: experiment A, where flax explants were grown on medium supplemented with 0.5 mg/l, 1 mg/l, and 1.5 mg/l Fe 3 O 4 NPs for callus culture obtaining, and experiment B, where calluses obtained from basal MS medium were transported into medium supplemented with concentrations of NPs identical to experiment A. Obtained results demonstrate similarly in both experiments that 25 nm Fe 3 O 4 NPs pass into callus cells and induce low toxicity level in the callus cultures. Nevertheless, calluses from experiment A showed 100% embryogenesis in comparison with experiment B where 100% rhizogenesis was noticed. It could be associated with different stress levels and adaptation time for explants and calluses that were transported into medium with Fe 3 O 4 NPs supplementation.

“…Different concentration of same nanoparticles elicits different effects on plant systems; i.e., low concentrations of nanoparticles may not show any adverse effect on plant, but higher concentrations may cause positive or negative effects on plants (Thuesombat et al 2014). Very recently, Zuverza-Mena et al (2016) suggested that both TiO 2 and ZnO have positive or negative phytotoxic effect. Boonyanitipong et al (2011) reported that ZnO nanoparticles inhibit the root length and reduce the number of roots.…”

With the development of nanotechnology, metal oxide nanoparticles have been applied in many industries, increasing their potential exposure level in the environment, yet their environmental safety remains poorly evaluated. Present work demonstrated the effects of ZnO and TiO 2 nanoparticles on the germination, morphoanatomical attributes and biochemistry of Cicer arietinum. The nanoparticles are used in three doses, i.e., 100, 500 and 1000 ppm along with control and each dose has three replicates. Results demonstrated that ZnO nanoparticles did not aid in the germination of seed, whereas TiO 2 nanoparticles showed positive impact on germination at 48-h observation. But at 72-h observation both the nanoparticle-treated and control seeds showed 100% germination. Morphological parameters revealed that ZnO nanoparticles have drastic negative impact on both root and shoot length, root and shoot fresh and dry biomass. On the other hand, the status of chlorophyll is almost opposite, i.e., ZnO nanoparticle-treated plants showed higher pigment content than TiO 2 nanoparticle-treated plants. From the statistical point of view, it is revealed that ZnO nanoparticle-treated plant showed significantly different results than that of TiO 2 nanoparticle-treated plants in Chl 'a' (p \ 0.001), Chl 'b' (p \ 0.001), total Chl (p \ 0.001) and carotenoid (p \ 0.001) content. Therefore, from these observations it can be concluded that ZnO nanoparticles showed positive effect on plant pigment content.Transverse sections of root clearly revealed the formation of vascular bundle, and parenchyma tissue is hampered in all the ZnO nanoparticle-treated plants. However, wellformed vascular bundles and other tissue systems are clearly visible for TiO 2 nanoparticle-treated roots. This work shows a combination of both positive and negative effects of ZnO and TiO 2 nanoparticles on a dicot plant. Present observation is very much important to understand the morphological, biochemical and anatomical alteration of plant system under the influence of ZnO and TiO 2 nanoparticles. This will help to utilize the nanoparticles in a managed way where nanoparticles with harmful effect on biological systems can be used in such a way to reduce their exposure to environment, and on the other hand, nanoparticles showing positive effect on biological systems may be used as growth enhancers or biofertilizers. Moreover, these results further strengthen our understanding of environmental safety information with respect to metal oxide nanoparticle.

“…This period seems to be still small to clarify all the aspects of the problem as required by the biosafety principles but sufficient for some preliminary principal conclusions. The data obtained indicate both positive and negative effects of metal nanoparticles on plants [98]. Factors that undoubtedly determine the processes of intracellular penetration of nanoparticles are their chemical nature, size, shape, surface charge, and dose.…”

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.
