The comparative efficacy of natural plant material and its callus culture was assessed for AgNP synthesis by employing both sunlight and microwave irradiation as separate synthesis methods. This yielded four distinct types of AgNPs denoted as CS-AgNPs, PS-AgNPs, CM-AgNPs, and PM-AgNPs. Sunlight-irradiated AgNP synthesis optimized at near to neutral pH (6.6), whereas microwave-assisted synthesis needed a basic pH for synthesis. Optimization of these AgNPs involved varying concentrations of AgNO₃, plant aqueous extract (PAE), and callus aqueous extract (CAE) of FS, exposure time to sunlight and microwave radiation, as well as pH adjustments. The particle size of these AgNPs ranged from 5 to 30 nm, having a crystalline nature with a similar fringe width of 0.22 nm, as observed from HR-TEM analysis. These AgNPs showed significant antibacterial properties against the clinical isolates with λmax 420 nm. Importantly, CAE outperformed PAE for the biosynthesis of AgNPs, mainly in the presence of sunlight-producing CS-AgNPs. These CS-AgNPs are rapidly synthesized, well dispersed and stable, showing significant antibacterial activity, and the least environmental phytotoxicity. It promoted the number of secondary roots, seedling DW, and TWC with 100% seed germination. This highlights their sustainable features for exploring industrial eco-friendly nonmanufacturing of AgNPs using callus culture and sunlight irradiation.</p></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"8 ","pages":"Article 100071"},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773111124000147/pdfft?md5=52900edd08cafdd7eb16a9fdce1be611&pid=1-s2.0-S2773111124000147-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140638726","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}

This study aimed to evaluate the fertigating potential of silica nanoparticles (SiNPs) in improving the physiochemical status, yield parameters, and seed nutritional qualities of the legumes exposed to salinity stress. Characterization of the synthesized SiNPs revealed amorphous, round-shaped particles, a size of 15–40 nm, and a surface charge of −6.18 mV. Different concentrations of SiNPs (0, 1, 5, 10 g/L) were applied to the plants in combination with four different concentrations of NaCl (0, 200, 400, 600 mM) during the reproductive phase of plants. The results indicated that the SiNPs (especially 10 g/L) efficiently reduced the negative impacts of salinity by improving the physiochemical parameters (growth, pigments, primary metabolites, antioxidant enzymes). Similarly, the improvement in yield parameters (pods per plant, pod length, seeds/10 pods, etc.) and seed nutritional attributes (protein, sugar, free amino acids, free fatty acid, polyphenol contents, etc.) were observed irrespective of the NaCl concentrations. Specifically, applying 10 g/L SiNPs enhanced the total pod numbers by 1.70, and 1.57 folds; and the total number of seeds/10 pods by 1.44, and 1.65 in lentil and soybean plants, respectively, compared to the control set (600 mM NaCl). Moreover, the seed protein content was augmented by 3.29, and 1.30 folds compared to the 600 mM NaCl stressed plants (lentil and soybean, respectively) when treated with 10 g/L SiNPs.

This review starts with an outline of the diverse pathways facilitating the accumulation of nanopesticides on plant cuticles, including their eventual transfer to the cuticles of insect pests. Subsequently, a comprehensive overview is provided of the micro- and nano-scale morphological features characteristic of plant and insect cuticles, along with the implications these features hold for their interactions with various nanopesticides. The review then focuses on interactions between nanopesticides and insect cuticles mediated through the plant cuticle. Finally, nanoscale mechanistic processes are discussed, with an emphasis on aspects such as wetting dynamics, critical length scales (e.g., inter-crystal spacing of waxes and surface wavelengths), and interdigitation and molecular adhesion processes of long-chain and macromolecular nanocarriers. Collectively, the review elucidates the essential interfacial processes governing the transfer and adhesion of nanopesticides between entities.

These changes pose a threat to global food security and livelihoods due to reduced yields, lower crop quality, and increased vulnerability to pests and diseases. To safeguard crops and build resilience, addressing climate change and adopting sustainable agricultural practices is crucial for sustainable productivity. The review highlights the chitosan based nanoconjugates potential as a tool to revolutionize agricultural practices and help to address the challenges posed by climate change on crop production and food security. Environmental stresses trigger a range of responses in plants, including changes to growth rate, productivity, cellular metabolism, and gene expression alterations. One of the paramount impacts of climate change on plants is water deficit stress, which disrupts water relations, causes metabolic disturbances, generates reactive oxygen species, and leads to crop damage. To counteract these adverse effects, chitosan, a naturally occurring polymer emerged as a promising biostimulator and elicitor in agriculture. Its non-toxic, biodegradable, and biocompatible properties make it well-suited for various applications. Chitosan enhances physiological responses in plants and helps to mitigate the negative impacts of abiotic stresses by activating stress transduction pathways. Chitosan nanoconjugates, formed by integrating chitosan with metallic nanoparticles, exhibit modified structural and functional properties, making them more effective in mitigating stress-related effects in plants. Their intelligent and slow delivery mechanisms contribute to their success in enhancing plant growth and development sustainably. Additionally, the encapsulation of metals or elements in chitosan reduces toxicity, enables slow-release properties, and ensures long-lasting effects. Nanoconjugates have been successfully utilized for priming agricultural and horticultural crops to enhance their tolerance to abiotic stress and promote sustainable yield improvement. Given their promising results, the use of nanoconjugates for priming agricultural crops and promoting sustainable yield improvement warrants continued exploration and development in the field of agricultural nanotechnology.</p></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"7 ","pages":"Article 100059"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773111124000020/pdfft?md5=36b9ea1f2feafa58d6a17f48a0b5c3e2&pid=1-s2.0-S2773111124000020-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139639431","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}
