Nanomaterials are increasingly popular among researchers due to their unique physicochemical properties and multifaceted applications. Recently, researchers are exploring more sustainable approaches for the synthesis of nanomaterials due to its numerous advantages. In this context, present investigation reports an approach for the synthesis of cobalt oxide nanosheets (Co₃O₄ NSs). This approach leverages environmentally friendly and sustainable methods, minimizing the use of hazardous chemicals and reducing energy consumption. Hence it involved <em>Withania somnifera</em> (ashwagandha) root extract as a greener reductant as well as stabilizing agent. The synthesized Co₃O₄ NSs were thoroughly analyzed using various techniques, including ultraviolet-visible (UV–vis) spectroscopy, fourier-transform infrared spectroscopy (FTIR), powder x-ray diffraction (PXRD), and field emission scanning electron microscopy (FE-SEM). A sharp absorption peak at 252 nm with a tail towards higher wavelength reveal the formation of Co₃O₄ NSs. The diffraction pattern reveals a face centered cubic structure of Co₃O₄ NSs. Morphological studies confirmed the substantial surface area of Co₃O₄ NSs which enable us to perform the catalytic degradation of azo dye, i.e., methyl orange. It provides that 10 mg of Co₃O₄ NSs is sufficient to degrade a 10 ppm aqueous methyl orange solution by 75.82 % in the dark and by 96.12 % under sunlight exposure. Thus, this study offers an excellent pathway for the synthesis of Co₃O₄ NSs and demonstrates their potential as a promising material for future catalytic applications.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100099"},"PeriodicalIF":0.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444557","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}

We have demonstrated that a nanohydroxyapatite (nHA)-mediated gene delivery system is effective in the transformation of reporter genes into six plant species. Despite the potential advantages of nHA-mediated biomolecule delivery and its application as fertilizers, phytotoxicity concerns necessitate additional studies. While initial findings suggest the beneficial effects of nHA as a nanofertilizer at specific concentrations, a thorough investigation into its bioactivity is warranted. This study reports the bioactivity of nHA on two model plants, including a crop species, and examines the global gene expression alterations in <em>Arabidopsis thaliana</em>. Treatment of seeds and seedlings with arginine-functionalized nHA (R-nHA) at concentrations at 50, 200 and 500 µg/ml led to accelerated germination in <em>Arabidopsis</em>, an effect not observed in <em>Nicotiana benthamiana</em>. Additionally, R-nHA did not affect root growth in either model species but significantly promoted root and leaf growth in <em>Triticum aestivum</em>. Transcriptomic analysis revealed minimal transcriptional changes in <em>Arabidopsis</em> treated with R-nHA compared to a water control, including activated phytohormone signaling pathways and stress-responsive genes. Salicylic acid (SA) has been identified as a pivotal phytohormone in initiating stress resistance in response to R-nHA exposure in <em>Arabidopsis</em>, highlighting its essential role in plant defense mechanisms against both biotic and abiotic stresses. In summary, this study showed that R-nHA accelerates germination and promotes plant growth with minimal transcriptional changes, thereby laying the groundwork for the use of nHA in plant genome manipulations. This research indicates that nHAs are highly biocompatible for plant bionanotechnology applications.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100093"},"PeriodicalIF":0.0,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142433077","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}

Both Zn-NC and ZnO-NPs were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD), and dynamic light scattering (DLS). Three concentrations (100, 200, and 500 ppm) of each compound, along with a control, were applied to local soil samples (n=3). The physiological (biomass, elongation) and biochemical effects (chlorophyll, carotenoids, flavonoids, and phenols) on wheat were investigated. Potential phytotoxic effects were evaluated to establish the biostimulants' safety thresholds. Plants treated with green Zn-NC showed an average increase in shoot length of 25 % compared to the control group. The chlorophyll content in plants treated with ZnO-NPs increased by 18 %, while those treated with green Zn-NC increased by 12 % compared to control. Application of ZnO-NPs resulted in a 30 % increase in total yield, whereas green Zn-NC treatment led to a 22 % yield increase. The root biomass of plants treated with ZnO-NPs increased by 28 %, and those treated with green Zn-NC saw a 20 % increase compared to controls. Based on the optimization of overall results, the ZnO NPs showed phytotoxic effects at concentrations above 200 ppm, while green Zn-NC exhibited no significant phytotoxicity even at concentrations up to 300 ppm. This study delineates the optimal concentrations of Zn-NC and ZnO-NPs that can enhance nutrient delivery and yield in cereal crops while mitigating phytotoxic risks.

Further, synthesized CaO NPs (0, 10, and 50 mg/L) were applied on fluoride-stressed (10 mg/L) rice seedlings to check its possible ameliorative effects towards growth and fluoride accumulation in different parts of rice seedlings.

Results of the seedling growth analysis revealed that CaO NPs inhibited the translocation of fluoride in rice plants, which in turn decreased the phytotoxicity caused by fluoride, including lipid peroxidation and chlorosis, and enhanced the overall growth of seedlings. The co-exposure of CaO NPs with fluoride also showed a reduction in the fluoride-induced oxidative stress, as demonstrated by lower MDA, O₂^•- contents, and activity of antioxidant enzymes (CAT, SOD, and POD) as compared to fluoride treatment alone. The application of CaO NPs also restored potassium content in seedlings grown under fluoride stress. Furthermore, the highest reduction of fluoride accumulation by 65 and 76 % in roots and shoots was recorded at 50 mg/L of CaO NPs treatment, respectively.
