In the current study, foliar spray with lanthanum (La) based nanomaterials (La10Si6O27 nanorods, La10Si6O27 nanoparticle, La(OH)3 and La2O3 nanoparticle) suppressed occurrence of sheath blight (Rhizoctonia solani) in rice. The beneficial effects were morphology-, composition-, concentration-dependent. Foliar application nanorods (100 mg/L) yielded greatest disease suppression, significantly decreasing severity by 62.4% compared infected controls; this level control was 2.7-fold greater than commercially available pesticide (Thifluzamide). order efficacy as follows: > nanoparticle nanoparticle. Mechanistically, (1) had bioavailability, slower dissolution, simultaneous Si nutrient benefits; (2) transcriptomic metabolomic analyses revealed that simultaneously strengthened rice systemic acquired resistance, physical barrier formation, antioxidative systems. Additionally, improved yield 35.4% promoted nutritional quality seeds Thifluzamide treatment. A two-year nanorod exposure no effect on soil health evaluated chemical, physical, biological properties. These findings demonstrate La can serve an effective sustainable strategy to safeguard crops highlight importance nanomaterial composition morphology terms optimizing benefit.

Fe-Based Nanomaterial-Induced Root Nodulation Is Modulated by Flavonoids to Improve Soybean (Glycine max) Growth and Quality

ACS Nano, Год журнала: 2022, Номер 16(12), С. 21047 - 21062

Опубликована: Дек. 8, 2022

Innovative technology to increase efficient nitrogen (N) use while avoiding environmental damages is needed because of the increasing food demand rapidly growing global population. Soybean (Glycine max) has evolved a complex symbiosis with N-fixing bacteria that forms nodules fix N. Herein, foliar application 10 mg L-1 Fe7(PO4)6 and Fe3O4 nanomaterials (NMs) (Fe-based NMs) promoted soybean growth root nodulation, thus improving yield quality over unexposed control, EDTA-control, 1 5 NMs. Mechanistically, flavonoids, key signaling molecules at initial steps in were increased by more than 20% upon exposure Fe-based NMs, due enhanced enzyme (phenylalanine ammonia-lyase, PAL) activity up-regulation flavonoid biosynthetic genes (GmPAL, GmC4H, Gm4CL, GmCHS). Accumulated flavonoids secreted rhizosphere, recruiting rhizobia for colonization. NMs Allorhizobium 87.3%, Mesorhizobium 142.2% 34.9%, leading 50.0% 35.4% respectively. Leghemoglobin content was also noticeably improved 8.2-46.5% The higher levels nodule number leghemoglobin resulted N 15.5-181.2% during whole period. Finally, (pod grain biomass) (flavonoids, soluble protein, elemental nutrients) significantly 14% Our study provides an effective nanoenabled strategy inducing efficiency, then both soybean.

Nanomaterials (NMs) hold significant potential for enhancing agricultural production, extending the shelf life, and maintaining quality of postharvest vegetables fruits. In this study, after foliar spraying with 1, 10, 50 mg L−1 Fe-P NMs at different stages (seedling, flowering, fruit stage), pepper plant growth was significantly improved. particular, application 10 during flowering stage found to be an optimal cultivation approach promote growth, yield, freshness peppers. Compared control group, increased net photosynthetic rate, height, number by 132.7%, 40.4%, 265.7%, respectively. The applied NMs, stage, altered capsaicin metabolic pathway, upregulating genes synthesis total phenols, flavonoids, lignans, capsaicinoids. Consequently, these metabolites, which are beneficial fruits, were increased. Furthermore, downregulated abundance rot-causing microorganisms (Enterobacter Chryseobacterium) upregulated (Pseudomonas, Arthrobacter, Sphingobacterium, Paenibacillus) change microbial community structure. This ultimately created a micro-ecological environment conducive preservation For comparison, storage, dipping NM suspensions effectively delayed weight loss enhanced bacteria. Nevertheless, effect less pronounced than preharvest application. study provides insights into pre- or improving performance

The physical properties of nano-fertilizers (NFs) are important in determining their performance, efficacy, and environmental interactions. Nano-fertilizers, due to small size high surface area-to-volume ratio, enhance plant metabolic reactions, resulting higher crop yields. depend on the synthesis methods used. nanoparticle’s nutrient use efficiency (NUE) varies among species. This review aims analyze relationship between NF influence performance uptake efficiency. focuses NFs, specifically size, shape, crystallinity, agglomeration. found that smaller particle-sized nanoparticles exhibit than larger particles. Nano-fertilizer-coated additives gradually release nutrients, reducing need for frequent application addressing limitations associated with chemical fertilizer utilization. shapes have varying effects overall plants. crystalline structure promotes a slow nutrients. Amorphous improve NUE and, ultimately, yield. Agglomeration results losing nanoscale accumulating outer surface, becoming unavailable Understanding is crucial optimizing agricultural applications.
