Green synthesis of metal nanoparticles represents an innovative and environmentally friendly approach in agriculture that enhances crop yield and quality. Unlike traditional physical and chemical methods, which are costly and produce harmful by-products, green synthesis uses biological agents like plants, fungi, and bacteria, making the process more sustainable and cost-effective. Bacterial cells demonstrate superior efficiency in the green synthesis of nanoparticles compared to plant cells. Their effectiveness is attributed to their unique morphological features, surface structures, and the presence of exopolysaccharides, sugars, proteins, enzymes, and various functional groups (such as carboxyl, phosphate, and amide). Interaction between bacterial cells and nanotechnology presents a promising approach for advancing smart agriculture by enhancing soil fertility, plant protection, and nanoparticle synthesis efficiency. By entering the structure of a living organism as an external factor, nanoparticles can cause extensive changes in the physiology and function of the cell. Therefore, the presence of a biological mediating agent with potential mechanisms capable of reducing the negative effects of nanoparticles can increase their efficacy as a long-term factor and reduce concerns about the harmful effects of nanoparticles on nature and living cells. By activating the pathways of NADPH, glutathione, and biofilm formation, this living agent first moderates the harmful effects of nanoparticles and acts as a filter, then provides them for the cell as a healthy biological-nanotechnological agent through a process known as green synthesis. Integration of nanoparticles and PGPR offers a novel and efficient approach to increasing plant productivity and sustainability in agriculture.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100111"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651236","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}

However, its short postharvest shelf-life results in significant losses, highlighting the need for effective strategies to extend its longevity. This study introduces a novel approach to monitoring and mitigating cassava deterioration by utilizing silver nanoparticle sensors to track hydrogen peroxide (H₂O₂) production, a key indicator of oxidative stress. Four economically viable cassava root cultivars were evaluated for their tolerance to postharvest physiological deterioration (PPD) and quality retention after treatment with various chitosan-antioxidant formulations. The results indicated that the chitosan-quercetin formulation (CS-Q) was the most effective, achieving the lowest average H₂O₂ reduction of 67.7 % compared to untreated samples, followed by chitosan-beta-carotene (CS-BC) at 62.4 %, chitosan-ascorbic acid (CS-AA) at 38.3 %, and chitosan (CS) at 34.8 %. These reductions in H₂O₂ suggest that chitosan-antioxidant treatments can effectively delay PPD and extend cassava's shelf life for up to six months, depending on the cultivar, seasonal factors, and specific antioxidant composition. The successful implementation of this innovation offers a promising solution to delay PPD and enhance the efficiency of the cassava supply chain. Furthermore, this study contributes to the advancement of electrochemical techniques for assessing PPD and demonstrates the potential of chitosan-based materials in improving the postharvest preservation of cassava and potentially other crops.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100115"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722197","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}

Wheat growth, productivity and seed quality has been extensively hampered by the aggression of seed-borne pathogens during post-harvest storage. The present work focus on the efficacy of chitosan-based Ag<sup>2+</sup> nanoparticles (Ag-CNPs) for the management of seed borne pathogens of wheat and their subsequent effects on growth, yield, and quality of harvested seeds. For this, healthy seeds of wheat were nanoprimed with Ag-CNPs and further inoculated with <em>A. flavus</em> so as to induce pathogenic stress. These seeds were sown in pots in a completely randomized block design and plants were raised from both nanoprimed and inoculated seeds, while plants were also raised from non-nanoprimed primed and uninoculated that served as control. Nanoprimed and pathogen inoculated seeds effectively increased vegetative growth such as (132.31 %), fresh weight (1.63-fold), dry weight (1.67-fold), and panicle length (137.03 %). and amplified the number of grains per spike, harvest index, ten kernel weight, and yield/plant, despite of pathogenic interference. Concomitantly, Ag-CNPs nano-priming enhances the harvested seed quality raised from pathogen inoculated seeds plants. The integrated density of the bands obtained in SDS-PAGE of variedly primed seeds revealed that Ag-CNP priming improved wheat's total protein profiling with a denser band intensity. The antioxidant enzymatic activity of CAT, POD, SOD, and NOX was traced maximum in Ag-CNPs primed seeds by 13.52, 7.90, 26.6 and 16.08 units, respectively. Thus, it can be concluded that nano priming with Ag-CNPs mitigated the wheat seeds from pathogenic stress and efficiently increased yield parameters and quality of harvested seeds.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698550","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}
