“…Numerous studies carried out on Mn uptake by plants and on Mn distribution among plant tissues have evidenced that Mn uptake is metabolically controlled, apparently in a way similar to that of other divalent cation species such as Mg 2+ and Ca 2+ [54], and its function is mainly related to the oxidation-reduction process. Several studies have been dedicated to wheat plants response to the application of Mn on wheat seeds and soil [68,69], while little information concerning Mn content in wheat is available [46,50]. Our data are close to those reported by Garnett and Graham [49] for steam of wheat grown in control soil within an experiment aimed to study the distribution and remobilization of iron and copper in wheat.…”

The present work aims to follow the influence of TiO2 nanoparticles (TiO2 NPs) on bioactive compounds, the elemental content of wheat, and on wheat leaves’ ultrastructure. Synthesized nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and transmission electron microscopy (TEM). The concentration of phenolic compounds, assimilation pigments, antioxidant capacity, elemental content, as well as the ultrastructural changes that may occur in the wheat plants grown in the presence or absence of TiO2 NPs were evaluated. In plants grown in the presence of TiO2 NPs, the amount of assimilating pigments and total polyphenols decreased compared to the control sample, while the antioxidant activity of plants grown in amended soil was higher than those grown in control soil. Following ultrastructural analysis, no significant changes were observed in the leaves of TiO2-treated plants. Application of TiO2 NP to soil caused a significant reaction of the plant to stress conditions. This was revealed by the increase of antioxidant capacity and the decrease of chlorophyll, total polyphenols, and carotenoids. Besides, the application of TiO2 NP led to significant positive (K, Zn, Br, and Mo) and negative (Na, Mn, Fe, As, Sr, Sb, and Ba) variation of content.

“…The literature almost entirely lacks articles that study both the effect of nitrate and sulfate of a particular element on plants, much less on wheat. We found only the work of Shtangeeva et al, [ 29 ] who studied silver-induced changes in the nutrient and trace element uptake by wheat and amount of the rhizosphere proteins. On the other hand, there are several studies [ 30 , 31 , 32 ] regarding the effects of Eu, Ce, Ca and Th nitrates on wheat.…”

“…As was previously mentioned, the literature is very poor with regard to data on the multielement content of wheat. Based on the mean values reported by Shtangeeva et al [ 29 ], for wheat root and leaves in control samples and in wheat grown with AgNO 3 and Ag 2 SO 4 , we calculated the translocation factor. The translocation factor value for K is almost 2, which is close to our values.…”

The Effect of Copper Salts on Bioactive Compounds and Ultrastructure of Wheat Plants

et al. 2022

Abiotic stress agents, among them metal stress, can cause oxidative damage to plant cells. In defense, plants can increase the production of secondary metabolites in order to mitigate the harmful effects caused by them. The purpose of this work was to evaluate the effect of two types of copper salts (CuSO4 and Cu(NO3)2), added in two different amounts in soil (150 mg/kg, respectively 300 mg/kg), on assimilating pigments, total polyphenols, antioxidant activity and the elemental composition of wheat. The obtained results were compared with those from control plants grown in the same conditions but without copper salts. The amount of assimilating pigments, total polyphenols, and antioxidant activity respectively increases or decreases in the plants treated with copper salts compared to the control depending on the stage of development of the plant. No significant damage induced in the leaves of the wheat plants treated with the selected salts was observed following the TEM analysis. In six-week-old plants it was observed by EDX analysis that the salts are transformed into nanoparticles. The bioactive compounds, elemental composition and their interaction is influenced by concentration of metal’s salt, type of salt and exposure period.

With the extensive utilization of nanotechnology, silver nanoparticles (AgNPs) are prevalent nanomaterials that may entail ecological risks by their potential translocation into plant systems. The present study investigated the physiological and molecular responses of basil seedlings (Ocimum basilicum) subjected to AgNPs or silver nitrate (AgNO3) for 7 days. The seedlings were treated with 0, 4, 10, or 40 mg/L of AgNO3 or AgNPs in Hoagland's solution. Both treatments resulted in signi cant accumulation of Ag in the roots and shoots, with higher levels in the roots of AgNO3-treated seedlings. AgNPs increased plant biomass at 4 mg/L, while AgNO3 decreased it at all concentrations. Both treatments reduced the total chlorophyll, carotenoids, and carbohydrates, with more pronounced effects in AgNO3-treated seedlings. Both treatments also induced oxidative stress, as indicated by increased levels of H2O2, MD, and proline, and enhanced activity of antioxidant enzymes SOD, CAT, and APX. However, these responses were more evident in AgNO3-treated seedlings, especially at higher concentrations. Quantitative real-time PCR analysis revealed that both treatments induced the upregulation of genes encoding oxidative stress tolerance-related enzymes, such as FSD1, MSD1, CSD1, CATa, CATb, APXa and APXb, in the basil seedling shoots. These results suggest that AgNPs are less toxic to basil plants than AgNO3 and that basil plants can activate physiological and molecular mechanisms to cope with Ag-induced oxidative stress.
