The inefficient utilization of nitrogen (N) in soil and drought stress seriously threatens agricultural food production. Herein, application carbon dots (CDs, 5 mg kg-1) promoted the growth nutritional quality soybeans by improving N bioavailability, which was beneficial to alleviate economic losses caused stress. Soil CDs enhanced N-fixing ability nodules, regulated rhizosphere processes, ultimately water uptake under Compared control (drought stress), soybean nitrogenase activity 8.6% increased content shoots roots 18.5% 14.8%, respectively. secretion root exudates (e.g., organic acids, fatty polyketides) microbial communities Proteobacteria, Acidobacteria, Gemmatimonadetes, Actinobacteria), thus enhancing release from soil. Besides, compared control, expression GmNRT, GmAMT, GmLB, GmAQP genes were upregulated 1.2-, 1.8-, 2.7-, 2.3-fold respectively, implying transport uptake. Furthermore, proteins, amino acids grains improved 3.4%, 6.9%, 17.3%, as a result bioavailability. Therefore, CD-enabled agriculture is promising for tolerance soybeans, significance security facing crisis global climate change.

Horticultural crop quality is an important aspect of agricultural production because it directly influences customer preference, market value, and overall sustainability. Micronutrients are for plant nutrition they affect the growth, development, horticultural crops. This review provides in-depth understanding role micronutrients in productivity. study investigated characteristics micronutrients, their functions growth most prevalent micronutrient deficits discusses obstacles issues associated with each treatment technique, including soil, foliar, fertigation application. It also emphasizes effects on quality, such as increased yield, improvements fruit attributes (size, color, flavor), nutritional value bioactive compounds, reduced postharvest losses, extended shelf life. Micronutrient plants have been studied, absorption, transport, accumulation, well interactions other nutrients signaling pathways. Recent research breakthroughs, studies specific synergies, innovative methods application formulation, developing technologies assessment, covered this review. The practical consequences recommendations management systems were investigated, concerns regarding sustainable efficient utilization future goals. Overall, underlines importance increasing productivity, potential influence subject.

Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner order to fulfill food demands an ever-increasing global population. However, intensive agricultural practices, rampant use agrochemicals, environmental factors result soil fertility degradation, pollution, disruption biodiversity, pest resistance, decline crop yields. Thus, experts are shifting their focus eco-friendly safer methods fertilization ensure sustainability. Indeed, importance plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, usage biofertilizers being actively promoted means mitigating harmful effects agrochemicals. As bio-elicitors, PPs promote growth colonize or tissues when administered soil, seeds, surface used alternative avoid heavy In past few years, nanotechnology brought revolution due application various nanomaterials (NMs) nano-based fertilizers increase productivity. Given beneficial properties NMs, these two can be tandem maximize benefits. combinations NMs PPs, synergistic use, its infancy but exhibited better crop-modulating terms improvement productivity, mitigation stress (drought, salinity, etc.), restoration fertility, strengthening bioeconomy. addition, proper assessment necessary before application, dose should applicable without showing any toxic impact environment microbial communities. The combo encapsulated within suitable carrier, this method aids controlled targeted delivery entrapped components increases shelf life PPs. review highlights functional annotation combined manner.

Abstract The use of nanofabricated materials is being explored for the potential in crop disease management. Chemically synthesized micronutrient nanoparticles (NPs) have been shown to reduce diseases; however, biogenic manganese NPs (bio‐MnNPs) control unknown. Here, and mechanism bio‐MnNPs suppression watermelon Fusarium wilt, caused by oxysporum f. sp. niveum ( Fon ) are reported. Bio‐MnNPs cell‐free cultural filtrate a waterrmelon rhizosphere bacterial strain Bacillus megaterium NOM14, found spherical shape with size range 27.0–65.7 nm. Application at 100 µg mL −1 increases Mn content roots/shoots improves growth performance through enhancing multiple physiological processes, including antioxidative capacity. suppress wilt inhibiting colonization invasive roots/stems, inhibit vegetative growth, conidiation, conidial morphology, cellular integrity. potentiate systemic acquired resistance triggering salicylic acid signaling upon infection, reshape soil microbial community improving fungal diversity. These findings demonstrate that ex planta mechanisms, offer promising nano‐enabled strategy sustainable management diseases.

Crop disease represents a serious and increasing threat to global food security. Lanthanum oxide nanomaterials (La2O3 NMs) with different sizes (10 20 nm) surface modifications (citrate, polyvinylpyrrolidone [PVP], poly(ethylene glycol)) were investigated for their control of the fungal pathogen Fusarium oxysporum (Schl.) f. sp cucumerinum Owen on six-week-old cucumber (Cucumis sativus) in soil. Seed treatment foliar application La2O3 NMs at 20-200 mg/kg (mg/L) significantly suppressed wilt (decreased by 12.50-52.11%), although efficacy was concentration-, size-, modification-dependent. The best achieved 200 mg/L PVP-coated nm); severity decreased 67.6%, fresh shoot biomass increased 49.9% as compared pathogen-infected control. Importantly, 1.97- 3.61-fold greater than that bulk particles commercial fungicide (Hymexazol), respectively. Additionally, enhanced yield 350-461%, fruit total amino acids 295-344%, improved vitamin content 65-169% infected controls. Transcriptomic metabolomic analyses revealed NMs: (1) interacted calmodulin, subsequently activating salicylic acid-dependent systemic acquired resistance; (2) activity expression antioxidant related genes, thereby alleviating pathogen-induced oxidative stress; (3) directly inhibited vivo growth. findings highlight significant potential suppressing plant sustainable agriculture.

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.
