Crop productivity worldwide is being hampered by salt stress. Nanotechnology and its applications in agriculture are noteworthy and fruitful. The current work investigates the potential significance of TiO2 NPs in alleviating salt stress in wheat cultivars. TiO2 NPs were prepared by green synthesis; their characterizations were carried out by UV–visible spectroscopy, SEM, and EDX. In the greenhouse control condition, different concentrations of salt (NaCl) with and without TiO2 NPs were administered to wheat crops. Plants treated with TiO2 NPs showed an enhanced germination rate, morphological, and metabolic profiling with and without salt stress. Different concentrations of TiO2 NPs (25, 50, 75, and 100 µg/mL) and salt solutions (NaCl 50, 100, and 150 mM) were used. TiO2 NP concentrations of 25 µg/mL and 50 µg/mL improved the germination attributes, physio-morphic parameters: plant length, the fresh and dry weight of plants, the number of leaves, the leaf area, the RWC, the MSI, and different chlorophyll contents at all saline conditions. These two concentrations also enhanced the biochemical attributes: free amino acids, soluble sugar content, proline content, SOD, and POD, of wheat varieties at all salinity levels. Wheat subjected to salt stress responded best to the application of TiO2 NPs at a concentration of 50 µg/mL. However, the highest concentrations (75 and 100 µg/mL) of TiO2 NPs showed detrimental effects on germination, agronomic, physiological, and biochemical attributes, and caused stress in both wheat varieties (Pirsabak-05 and NARC-09) under control and saline conditions. The outcomes of the current research work are notable, and NPs with such capabilities may be a useful supply of fertilizer in the agricultural industry.

“…From the TGA analysis result, even when the MSNs were completely dry, they had still adsorbed water electrostatically, and this water may be available for root uptake. Recently, Mitra et al (2022) demonstrated the beneficial roles of MSNs over conventional Si NPs for enhancing plant growth, reducing stress, and promoting basic metabolic rates in the dicot Vigna radiata. These authors also proposed that the pores of MSNs were filled with ions present in the MS media, which may increase their availability to emerging seedling roots.…”

Mesoporous silica nanoparticle-induced drought tolerance in Arabidopsis thaliana grown under in vitro conditions

et al. 2023

Nanoparticles of varying formats and functionalities have been shown to modify and enhance plant growth and development. Nanoparticles may also be used to improve crop production and performance, particularly under adverse environmental conditions such as drought. Nanoparticles composed of silicon dioxide, especially those that are mesoporous (mesoporous silica nanoparticles; MSNs), have been shown to be taken up by plants; yet their potential to improve tolerance to abiotic stress has not been thoroughly examined. In this study, a range of concentrations of MSNs (0-5000 mg L −1 ) were used to determine their effects, in vitro, on Arabidopsis plants grown under polyethylene glycol (PEG)-simulated drought conditions. Treatment of seeds with MSNs during PEG-simulated drought resulted in higher seed germination and then greater primary root length. However, at the highest tested concentration of 5000 mg L −1 , reduced germination was found when seeds were subjected to drought stress. At the optimal concentration of 1500 mg L −1 , plants treated with MSNs under non-stressed conditions showed significant increases in root length, number of lateral roots, leaf area and shoot biomass. These findings suggest that MSNs can be used to stimulate plant growth and drought stress tolerance.

“…To prevent contamination, cleansing and sterilization of seeds are necessary, for which seeds were rinsed with water continuously for 2 hours. Surface sterilization of seeds was done using 5% sodium hypochlorite (Merck Millipore, USA) and Teepol (Merck) solution for 20 min, followed by rinsing with DI water [Mitra et al, 2021;Mitra et al, 2022]. After that, seeds were soaked in 1% potassium permanganate (SRL) solution for another 20 min and washed with autoclaved Milli-Q water.…”

Cerium oxide nanoparticles have so far been investigated for their role as an antioxidant in pathologies involving in ammation and high oxidative stress. However, its role as a plant and bacterial growth modulator and heavy metal stress reliever has been overlooked to date. Heavy metal contamination poses a major threat to mankind and a life-sustaining ecosystem. This study emphasizes the role of cerium oxide produced by the combustion method in promoting growth in Vigna radiata and Bacillus coagulans in presence of mercury. The results show how cerium oxide nanoparticles successfully reduce the production of reactive oxygen species in plants grown in presence of mercury thereby reducing oxidative stress. It also throws light upon the biologically non-hazardous nature of this particle by revealing how it promotes the growth of two soil bacteria Bacillus coagulans and E.coli at various dosages.
