“…On the contrary, positive effects of Ag NPs were reported in Phoenix dactylifera (L.) Mill. in vitro cultures (Elsayh et al, 2022). When 3 ml • L −1 Ag NPs were added to the medium at the multiplication stage, the longest shoots with the highest number of leaves were obtained.…”

Nanotechnology creates opportunities to improve the micropropagation of horticultural plants. The aim of this study was to test the effects of zinc oxide submicron particles (ZnO SMPs), and nanoparticles (NPs) such as ZnO NPs, and ZnO+Ag NPs, at the concentrations of 100, 200, or 400 mg·L−1, on the growth parameters of Chrysanthemum × morifolium (Ramat.) Hemsl. ‘UTP Burgundy Gold’ and ‘UTP Pinky Gold’ plantlets propagated by shoot-tip culture on MS medium. Control shoot culture (without SMPs or NPs) and culture with auxin (MS with indole-3-acetic acid IAA) were also evaluated. Treatments with SMPs, NPs, and IAA stimulated the formation of leaves. Most often, plantlets treated with SMPs and NPs, especially with 100 and 200 mg·L-1 ZnO SMPs, 100 mg·L-1 ZnO NPs 1.5% H2O, and 100 mg·L-1 ZnO+1% Ag NPs 1.5% H2O, produced leaves with the highest area, perimeter and horizontal width, compared to the control and the IAA treatment. Generally, shoot fresh and dry weights of plantlets treated with SMPs, NPs or IAA were higher compared to the control. The highest shoot fresh and dry weights were stated for 400 mg·L-1 ZnO+1%Ag NPs 6% H2O and 100 mg·L-1 ZnO SMPs, respectively, whereas the lowest shoot fresh and dry weights were found for 400 mg·L-1 ZnO+1%Ag NPs 1.5% H2O. The highest values of root system fresh and dry weights were reported for IAA. Contrary, application of 400 mg·L-1 ZnO+0.1%Ag NPs 6% H2O, ZnO+1%Ag NPs 1.5% H2O, and ZnO+1%Ag NPs 6% H2O resulted in the lowest fresh and dry weights of root systems. The auxin treatment also resulted in the highest length, area, and volume of the root system, as well as root diameter and number of root tips and forks. Nevertheless, the treatments with ZnO SMPs and ZnO NPs most often increased the root system parameters against ZnO+Ag NPs. The results are of scientific and practical importance for modulating chrysanthemum plantlets’ architecture during micropropagation.

“…Research on the correlation between NPs and SE is focused mainly on the effect of NPs on the efficiency of SE and the NPs’ influence on the physiological processes that occur at the various stages of SE (e.g., [ 20 , 21 , 22 , 23 , 24 , 25 ]). These studies so far indicate that NPs in plant tissue cultures give positive results and enhance plant regeneration (e.g., [ 23 , 26 ]).…”

Although the influence of nanoparticles (NPs) on developmental processes is better understood, little is known about their impact on somatic embryogenesis (SE). This process involves changes in the direction of cell differentiation. Thus, studying the effect of NPs on SE is essential to reveal their impact on cell fate. This study aimed to examine the influence of gold nanoparticles (Au NPs) with different surface charges on the SE of 35S:BBM Arabidopsis thaliana, with particular emphasis on the spatiotemporal localization of pectic arabinogalactan proteins (AGPs) and extensin epitopes in cells changing the direction of their differentiation. The results show that under the influence of nanoparticles, the explant cells of 35S:BBM Arabidopsis thaliana seedling origin did not enter the path of SE. Bulges and the formation of organ-like structures were observed in these explants, in contrast to the control, where somatic embryos developed. Additionally, spatiotemporal changes in the chemical composition of the cell walls during the culture were observed. Under the influence of Au NPs, the following effects were observed: (1) explant cells did not enter the SE pathway, (2) the impacts of Au NPs with different surface charges on the explants were variable, and (3) the compositions of the analyzed pectic AGPs and extensin epitopes were diverse in the cells with different developmental programs: SE (control) and non-SE (treated with Au NPs).
