Exposure of tomato (Lycopersicon esculentum) to silver nanoparticles and silver nitrate: physiological and molecular response

Biosynthesis of ZnO Nanoparticles Using Bacillus Subtilis: Characterization and Nutritive Significance for Promoting Plant Growth in Zea mays L

“…The positive and toxicity effects depend on dose, nature, duration and conditions of exposure. 42 , 43 Normally, nanoparticles effects plant physiological traits i.e. germination, root elongation and biomass 44 - 46 The nanoparticles may cause reduction in seed germination, plant elongation and sometime cause plant death.…”

Silver nanoparticle pollutants activate oxidative stress responses and rosmarinic acid accumulation in sage

“…According to the obtained results, the accumulation of MDA suggests that membrane damage happened in exposed leaves. The production of MDA has previously been reported in different plant species such as Crambe abyssinica (Ma et al 2015b), and Lycopersicon esculentum (Noori et al 2019), treated with SNPs.…”

“…The uses of SNPs for agricultural, industrial and domestic purposes introduce new pollutants to the environment that potentially threaten plant health in both managed and natural ecosystems (Carlson et al 2008, Cox et al 2017). Effects of SNPs have been demonstrated for several plant species and the increasing uses of SNPs necessitate studies on their dose‐dependent effects on plant health and potential mechanisms behind such effects (Geisler‐Lee et al 2012, Jiang et al 2012, Lee et al 2012, Dimkpa et al 2013, Qian et al 2013, Yasur and Rani 2013, Geisler‐Lee et al 2014, Hatami and Ghorbanpour 2014, Nair and Chung 2014a, 2014b, Kohan‐Baghkheirati and Geisler‐Lee 2015, Thiruvengadam et al 2015, Homaee and Ehsanpour 2016, Park and Ahn 2016, Jasim et al 2017, Vishwakarma et al 2017, Chung et al 2018, Li et al 2018,, Noori et al 2019). In the present study, we showed strong dose‐dependent responses of S. officinalis plants to SNPs exposure.…”

“…Previous studies have also exhibited that the SNPs-related stresses resulted in reduced chlorophyll content in Arabidopsis (Qian et al 2013), Brassica sp. (Vishwakarma et al 2017), Lycopersicon esculentum (Noori et al 2019) and Oryza sativa (Nair and Chung 2014b). In general, the decrease of photosynthetic pigments content is a common effect of metal-based NPs (Ma et al 2015a).…”

“…Various microscopic techniques are used to confirm the uptake and delivery of NPs in the plant systems and inductively coupled plasma‐mass spectroscopy (ICP‐MS) is used to analyze metal accumulation in plants (Raliya et al 2016, Du et al 2017). The accumulation of NPs has been reported in many plant species such as Arabidopsis thaliana , Brassica sp., Triticum aestivum , Solanum tuberosum , Trigonella foenum‐graecum , Allium cepa , Oryza sativa , Daucus carota , Crambe abyssinica , Ricinus communis , Citrus sinensis , Pelargonium zonale , Phaseolus radiates and Lycopersicon esculentum with considerable effects on their growth and development (Kumari et al 2011, Geisler‐Lee et al 2012, Lee et al 2012, Dimkpa et al 2013, Yasur and Rani 2013, Geisler‐Lee et al 2014, Hatami and Ghorbanpour 2014, Nair and Chung 2014a, 2014b, Thiruvengadam et al 2015, Homaee and Ehsanpour 2016, Park and Ahn 2016, Jasim et al 2017, Vishwakarma et al 2017, Li et al 2018, Noori et al 2019). SNPs can generate reactive oxygen species (ROS) and consequently stimulate oxidative stress responses via activation of antioxidant enzymes including superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) and also the production of non‐enzymatic antioxidants such as carotenoids, glutathione, ascorbic acid and proline (Zhang et al 2013, Li et al 2018).…”
