“…The potential effects of AgNPs on plants, especially on edible crop plants, should be evaluated before their widespread application (Kumari et al, 2009;Lee et al, 2012;Qian et al, 2013). Solanum lycopersicum L. is an important edible plant around the world; hence the aim of our study was to examine the effects of AgNPs (<100 nm) on DNA damage, genomic template stability, the antioxidant defense system, and lipid peroxidation in tomato plants.…”

IntroductionSilver nanoparticles (AgNPs) are widely used among other nanoparticles in many industries within a wide range of consumer products because of their antibacterial and biocidal properties (Thuesombat et al., 2014). In recent years, the significant increase in the consumption of nanoparticles has caused environmental, health, and safety concerns regarding their potential effects (Ma et al., 2010;Pokhrel and Dubey, 2013). Nanoparticles could uncertainly spread to the environment. However, the interaction between AgNPs and plant systems is still not well known (Patlolla et al., 2012;Song et al., 2013).AgNPs are known to be absorbed by plants and could interact with intracellular parts causing water imbalances, cell damage, and decreases in photosynthesis (Kumari et al., 2009;Qian et al., 2013). They are also reported to have genotoxic effects on plant cells, inducing chromosomal aberrations and micronucleus induction (Patlolla et al., 2012). However, the impacts of nanoparticles on plants can vary according to the nanoparticle concentration, size, chemical properties, and plant species (Ma et al., 2010;Thuesombat et al., 2014).Nanotoxicity could lead to oxidative stress and previous studies indicate that AgNPs could induce toxicity due to their effect on reactive oxygen species (ROS) formation (Qian et al., 2013;McShan et al., 2014). The imbalance of ROS production and antioxidant activity can cause oxidative damage, and plants cope with this oxidative damage by their antioxidant defense mechanism (Saed-Moucheshi et al., 2014). Previously, studies on the genotoxicity of nanoparticles have used cell viability, chromosome aberration, or micronucleus assays to identify the genotoxic effect, and comet analysis for detecting the DNA damage in different plant species (Kumari et al., 2009;Kumari et al., 2011;Patlolla et al., 2012;Ghosh et al., 2012). However, these methods are very restricted for identifying the genotoxic effects of nanoparticles at the DNA level. DNA-based techniques are sensitive and selective assays that help to determine the genotoxic effects of environmental pollutants on DNA. One of these methods used for these aims is the intersimple sequence repeat (ISSR)-PCR assay. ISSR-PCR uses as primer microsatellite repeats (Zietkiewicz et al., 1994). The ISSR-PCR method is more sensitive than the random amplified polymorphic DNA assay (RAPD) (Correia et al., 2014;Bajpai et al., 2015), because of the exhibiting specificity of the sequence-tagged-site markers and high ratio of reproducibility potential owing to the use of longer primers (16-25 bp).

“…Inhibition of growth depending on the Ag NP dose and exposure was demonstrated for Lemma minor L. [74]^ signs of oxidative stress and changes in the structure of chloroplasts were observed at high concentrations. In Phaseolus radiates L. and Sorghum bicolor L. the growth inhibition due to the addition of Ag NPs was more pronounced on the culture media, but not in the soil [75]. The particle size also affects toxic effects.…”

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.

Nanosilver particles adhere strongly to plant tissues and cause an increase in the activation of enzymes involved in secondary metabolite production.…”

Tropane and Granatane Alkaloid Biosynthesis: A Systematic Analysis

et al. 2016

View full text Add to dashboard Cite

Abstract:The tropane and granatane alkaloids belong to the larger pyrroline and piperidine classes of plant alkaloids, respectively. Their core structures share common moieties and their scattered distribution among angiosperms suggest that their biosynthesis may share common ancestry in some orders, while they may be independently derived in others. Tropane and granatane alkaloid diversity arises from the myriad modifications occurring to their core ring structures. Throughout much of human history, humans have cultivated tropane-and granatane-producing plants for their medicinal properties. This manuscript will discuss the diversity of their biological and ecological roles as well as what is known about the structural genes and enzymes responsible for their biosynthesis. In addition, modern approaches to producing some pharmaceutically important tropanes via metabolic engineering endeavors are discussed.
