“…An increase in the concentration of nanoparticles to 1600 ppm, however, led to a decrease in the parameter to 40%. The authors also found that when the concentration of ZnO was 1200 ppm, there was a maximum increase in the plant biomass [78]. These results may be used to create conditions for better rooting of plants during clonal micropropagation and to transfer microclones from a test tube to soil conditions.…”

The search for effective and nontoxic sterilization drugs for plants against common phytopathogenic microorganisms is a major challenge to improve the biotechnology of plant clonal micropropagation. An analysis of 92 studies that describe the potential use of ZnO and TiO 2 nanoparticles as antimicrobial agents in biotechnology showed that their biological effects depend on several factors: photocatalytic activity, particle size, concentration, morphology, and surface modification. The mechanisms of toxicity, among which the primary one is generation of reactive oxygen species leading to oxidative stress, are also due to these factors. The data describing the direct influence of ZnO and TiO 2 nanoparticles on plants, however, are contradictory, which is probably because of the various particle shapes and sizes, their concentrations, and the species characteristics of the plants studied. These studies have confirmed that photocatalytically active ZnO and TiO 2 nanoparticles may be used as bactericidal and fungicidal drugs for sterilization of explants during clonal micropropagation of plants, while taking into account the possible phytotoxicity of these particles.

“…Однако увеличение концентрации наночастиц до 1600 миллионных долей привело к снижению анализируемого показателя до 40%. Также авторами отмечено, что при 1200 миллионных долях ZnO наблюдался максимальный прирост биомассы растений [78]. Показанные результаты могут быть использованы при создании условия для лучшего укоренения растений при клональном микроразмножении, при переносе микроклонов из пробирки в условия грунта.…”

Поиск эффективных против распространенных фитопатогенных микроорганизмов, но при этом не токсичных для растений стерилизующих препаратов является важной задачей для совершенствования биотехнологии клонального микроразмножения растений. Проведенный обзор 92 исследовательских работ, посвященных потенциальному использованию наночастиц ZnO и TiO2 в качестве антимикробных агентов в биотехнологии, показал, что эффекты их биологического воздействия зависят от ряда факторов: фотокаталитической активности, размера частиц, концентрации, морфологии и модификации поверхности. С этими факторами также связаны механизмы токсичности, в качестве основного из которых рассматривается генерация активных форм кислорода, что приводит к окислительному стрессу. Однако данные, касающиеся непосредственного воздействия наночастиц ZnO и TiO2 на растения, противоречивы, что, вероятно, связано с разнообразием исследованных авторами форм и размеров частиц, их концентраций, а также видовых особенностей растений. Результаты проанализированных исследований подтверждают перспективность использования фотокаталитически активных наночастиц ZnO и TiO2 в качестве бактерицидных и фунгицидных препаратов для стерилизации эксплантов в ходе клонального микроразмножения растений, однако с учетом возможной фитотоксичности этих частиц.

“…It was observed that Zn NPs can greatly influenced plant growth, yield, and fatty acid profiles of maize ( Taheri et al, 2016 ). An increase in germination percentage and root length of maize plants was observed after exposure to zinc oxide nanoparticles (ZnO NPs) ( Meena et al, 2017 ), whereas increased shoot length was observed in oat and berseem plants ( Maity et al, 2018 ). It was also confirmed that ZnO NPs enhance the plant growth and increased root biomass of the Glycine max plant ( De la Rosa et al, 2013 ).…”

Plants are indispensable on earth and their improvement in terms of food security is a need of time. The current study has been designed to investigate how biogenic zinc nanoparticles (Zn NPs) can improve the growth and development of Brassica napus L. In this study, Zn NPs were synthesized utilizing Mentha arvensis aqueous extracts, and their morphological and optical properties were assessed using UV-Visible spectrophotometry, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The synthesized Zn NPs were irregular in shape, indicating aggregation in pattern, with an average particle size of 30 nm, while XRD analysis revealed the crystalline structure of nanoparticles. The growth and development of B. napus varieties (Faisal canola and Shiralee) were assessed after foliar treatments with different concentrations of biogenic Zn NPs. In B. napus varieties, exposure to 15 mg/L Zn NPs dramatically increased chlorophyll, carotenoid content, and biomass accumulation. Similarly, proteomic analyses, on the other hand, revealed that proteins associated with photosynthesis, transport, glycolysis, and stress response in both Brassica varieties were substantially altered. Such exposure to Zn NPs, differential expression of genes associated with photosynthesis, ribosome structural constituents, and oxidative stress response were considerably upregulated in B. napus var. (Faisal and Shiralee canola). The results of this study revealed that foliar applications of biogenic Zn NPs influence the transcriptome and protein profiling positively, therefore stimulating plant growth and development.
