Nanoparticles have been employed as gene regulatory systems that can efficiently modulate gene expression owing to their unique physiochemical properties. Exposure to metal, metal oxide, carbon and polymer-based nanomaterials can lead to arbitrary DNA methylation and thus damage targeted cells by generating oxidative stress genes in mammals and bacteria. However, the valuable role of carbon-based nanoparticles in the suppression of tumor growth factor genes or genes attributed to inhibition of angiogenesis is an innovative approach in medical science, which may stop the progression of abnormal cells. Predominantly, nanoparticles induced the genes involved in oxidative stress, DNA methylation, pro-inflammatory reactions, signaling pathways, cell proliferation and differentiation. The expression of toxin-antitoxin genes in bacteria is also controlled by nanoparticles, such as ZnO, which inhibits biofilm formation in bacteria and is responsible for antibiotic resistance. Exposure of plants to several types of nanoparticles upregulated the genes involved in shielding the plants against oxidative and abiotic stresses, predominantly salinity stress. Gene modulation by nanoparticles in different organisms or species is not uniform.

Plants, being sensitive to alterations in their surroundings, must evolve complex defense systems against these changes, particularly in the case of abiotic stress, which would otherwise diminish plant productivity. Nano-encapsulation and seed nanopriming are two avant- garde approaches that have the potential to alter the sustainability of agroecosystems. Seed nanopriming involves the strategic application of nanoparticles (NPs) to seeds for crop improvement. Applying NPs through seed priming is a novel and economical method that enhances germination of seeds and plant growth by stimulating physiological processes in plants &amp; offering resilience towards diverse stressors. While on the other hand smart agriculture has reduced reliance on conventional agrochemicals, nano-encapsulation of bioactive compounds offers a complementary approach by providing a long-lasting and controlled release of essential agrochemicals or compounds by using different types of nanocarrier. This review provides insights into recent developments in agriculture, focusing on the opportunities that are associated with the use of nanotechnology for seed nanopriming. In addition, it highlights the materials and technologies that are employed in encapsulating the bioactive compound with NPs. In addition to offering an in-depth review of the benefits and drawbacks of each technique, this study explores the potential of nano-encapsulation and nanopriming to increase agricultural output. It goes into more detail on the technologies' economic worth, emphasizing how they might raise crop yields and profitability.

The isolated PGPR was characterized by 16sRNA and its phylogenetic analysis revealed it as <em>Bacillus pulumis.</em> Isolate was examined for its plant growth promotion potential and stress alleviating capabilities. SiNP was utilized as a potential amendment to enhance these effects. <em>Bacillus pulumis</em> showed IAA production, ACC deaminase activity, phosphate solubilisation and siderophore production attributes. Fluorescence microscopy conducted in vivo confirmed the accumulation of reactive oxygen species (ROS), as supported by elevated MDA concentration and reduced membrane permeability. Exposure of <em>Brassica juncea</em> seedlings to 5 μM pendimethalin led to a marked increase in reactive oxygen species (ROS), with superoxide radicals (SOR) rising by 125.58 % and hydrogen peroxide (H₂O₂) by 159.32 % in roots, compared to the control. The combined application of PGPR and SiNP significantly mitigated this stress, reducing SOR and H₂O₂ levels to 27.91 % and 35.59 % respectively. This reduction is linked to enhanced antioxidant defence mechanisms, as the activities of superoxide dismutase (SOD) and catalase (CAT) increased by 22.76 % and 28.38 %, respectively, in root of seedlings co-treated with SiNP and PGPR. Pendimethalin alone reduced dehydroascorbate reductase (DHAR) and monodehydroascorbate reductase (MDAR) activity in roots by 28.95 % and 42.11 %, respectively. However, individual supplementation of SiNP and PGPR mitigated this suppression, with drop in DHAR activity reduced to only 12.63 % and 11.58 %, and MDAR by 17.54 % and 22.81 %, respectively. Co-application of SiNP and PGPR further alleviated this inhibition, limiting DHAR reduction to 9.47 % and MDAR to 3.51 %. This suggests that pendimethalin toxicity causes oxidative stress through disruption of redox balance and over production of ROS and the combined action of SiNP and PGPR enhances the antioxidant system, which likely explains the synergistic effect in alleviating pendimethalin-induced toxicity. The co-application of PGPR and SiNP significantly enhanced plant growth parameters, increased photosynthetic pigment content, improved membrane stability, and reduced lipid peroxidation in both leaves and roots. This research underscores the potential of PGPR and SiNP in sustainable agriculture, particularly in mitigating herbicide-induced stress in crop plants.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"11 ","pages":"Article 100126"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At low concentrations, NMs can promote plant growth and development, but at higher doses, they may become toxic, causing oxidative stress, membrane damage, and disrupting key physiological processes.

The AgNPs were spherical with diameter ranges between 30 and 90 nm, negatively charged at −29.6 mV, crystalline in nature and surrounded by different active functional groups as evident by FTIR spectra analysis. The presence of phenolic compounds such as gallic acid and catechin were confirmed through HPLC analysis, providing insights into the bio-reduction mechanism which facilitate the conversion of Ag+ to AgNPs. Antimicrobial properties of the synthesized AgNPs were assessed against four Gram-negative and two Gram-positive bacteria with maximum zone of inhibition against <em>Staphylococcus aureus</em> (20±3.00 mm) and <em>Micrococcus luteus</em> (20±1.73 mm). The antibacterial potential of AgNPs is primarily linked with the increased cell membrane permeability of AgNPs treated bacterial cells (<em>E. coli</em>, <em>S. aureus</em> and <em>M. luteus</em>) as evident by measuring increased conductivity and elevated extracellular DNA concentration due to the disruption of bacterial cell membrane.

Understanding the transport of plant nutrients in the soil is crucial for effectively managing nanofertilizer applications and minimizing their impact on the environment. This study investigated phosphorus transport in agricultural soil using 15-day and 30-day soil column experiment data from 2017 and 2018. Two soil column experiments were conducted using nano-rock phosphate, nano-hydroxyapatite fertilizers, and a commercial fertilizer (single super phosphate). The Hydrus 1D model was used to understand the transport mechanism of nano and bulk phosphorus fertilizers. Water and dissolved phosphorus fluxes were simulated using leachate data, and key phosphorus transport parameters, including longitudinal dispersivity and the diffusion coefficient, were determined. The Hydrus-1D model accurately captured leachate dynamics (R² = 0.82–0.99 and MAE = 0.38–0.56 cm/days). Phosphorus transport performed well for bulk fertilizer treatments (R² = 0.86–0.90, MAE = 0.08–0.19 ppm, and RMSE = 0.14–0.36 ppm). However, mixed results were obtained while validating nano fertilizer treatments (R² = 0.31–0.98, MAE = 0.046–0.41 ppm, and RMSE = 0.084–0.35 ppm). For nanofertilizers, the longitudinal dispersivity and distribution coefficient were reduced by 80.71 % and 19.20 %, respectively, compared to commercial fertilizers. The lower longitudinal dispersivity indicates that nano fertilizers release nutrients more slowly than bulk fertilizers. Similarly, a smaller distribution coefficient suggests that nano-phosphorus fertilizers are more concentrated in specific areas within the soil, leading to slower and more controlled nutrient distribution. Additionally, the leachate's observed total phosphorus concentration and the soil profile's phosphorus concentration support the study findings. The results indicate that the transport mechanism of nano and bulk fertilizers in soil is distinct and should be treated separately.
