Enhancing soybean germination and vigor under water stress: the efficacy of bio-priming with sodium carboxymethyl cellulose and gum arabic

Frontiers in Plant Science, Год журнала: 2025, Номер 15

Опубликована: Янв. 3, 2025

Seed priming can significantly enhance the tolerance of soybean against different environmental stresses by improving seed water uptake and modulating stress-response mechanisms. In particular, with sodium carboxymethylcellulose (SCMC) gum Arabic (GA) support seeds to withstand extreme conditions better, promoting more consistent germination robust seedling establishment, which is crucial for achieving stable agricultural yields. The present study investigated effects using a combination SCMC GA (10% CG) on germination, growth, biochemical responses six varieties under drought flooding stress conditions. results revealed significant differences among applied treatments vigor, physiological traits. Under stress, 10% CG improved percentage, rate, shoot length, root biomass compared unprimed seeds. Notable reductions in malondialdehyde (MDA) content enhanced antioxidant enzyme activities, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), suggest that mitigates oxidative damage through defense Moreover, growth parameters but advantages were less significant. addition, treatment reduced electrolyte conductivity (EC) across all seeds, indicating membrane stability. Overall, was effective conditions, demonstrating potential strategy enhancing varieties.

Preparation of a Self-Assembled Nanoantiviral Pesticide with Strong Adhesion Performance for Efficiency Control of Destructive Soybean Mosaic Virus

Journal of Agricultural and Food Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

In this context, we reported for the first time design and development of a self-assembled nanoantiviral pesticide based on star polycation (SPc) broad-spectrum fungicide/antiviral agent seboctylamine field control Soybean mosaic virus (SMV), highly destructive plant in soybean crops. The SPc could self-assemble with through hydrogen bonds van der Waals forces, complexation reduced particle size to form spherical seboctylamine/SPc complex. addition, contact angle decreased, its retention increased aid SPc, indicating excellent wetting properties strong leaf surface adhesion performance. incorporation significantly inhibited viral accumulation plants enhanced efficacy against SMV, resulting improved agronomic traits. Overall, our study would contribute facilitating new strategy effective SMV soybeans.

Selenium-Containing Nanoformulations Capable of Alleviating Abiotic Stress in Plants

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(4), С. 1697 - 1697

Опубликована: Фев. 17, 2025

Climate changes cause various types of abiotic stress in plants, thus affecting plant growth and causing decline yield. An urgent need exists to develop an environmentally friendly attitude based on principles sustainable agriculture. Nanomaterials may improve enhance crop productivity by handling the conditions considered stressful for plants a ecofriendly manner. Selenium (Se) has been put into category beneficial elements plants. Se-enriched crops present successful choice dietary resource Se-supplemented food feed owing their high bioavailability accessibility. Researchers from distinct areas, including both nanoscience science, should encourage emerging innovations that are linked with production. The implementation Se nanoparticles (SeNPs) is one predominating mechanisms ameliorate conditions. Increasing evidence earlier research revealed SeNPs could development, nutrient bioavailability, soil fertility, response while maintaining environmental safety. Meanwhile, some studies reported might have multilateral influence dependent diverse nanomaterial traits, doses, species. More efforts required knowledge how impact exposed different detrimental factors. In light contemporary challenges prolonged application nanomaterials aim this review elucidating principal fruitful areas SeNP exploration, comparisons bulk Se, insights alleviation existing uncertainties, practical applications under varying environments.

AgNPs biosynthesized from Pseudomonas Z9.3 metabolites as antimicrobial agents against bacterial and fungal pathogens

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Опубликована: Апрель 7, 2025

An eco-friendly method for the biosynthesis of functional silver nanoparticles (AgNPs) using plant growth-promoting bacteria (PGPB), specifically Pseudomonas sp. Z9.3, has been developed. The growing need sustainable and non-toxic nanoparticle production makes this significant various applications. influence physicochemical parameters, such as temperature, pH, concentrations AgNO3, on synthesis AgNPs was studied. formation confirmed by UVvis, SEM/TEM, FTIR, XRD analysis. Antibacterial activity assessed antibacterial disk diffusion assay. For antifungal activity, were added to agar medium, size inhibition zone measured. Two optimal conditions identified: 37°C, pH 9, a 5:1 ratio bacterial supernatant 5 mM AgNO3 (S1-9), 7, with 2:4 (S4-7). UV-visible spectroscopy results showed an absorption range between 400 450 nm, confirming AgNPs. SEM TEM analysis spherical shape good distribution average ranged from 8.24 ± 0.26 13.32 0.4 nm. against different pathogenic fungi tested. six human pathogens three phytopathogens evaluated. potential S1-9 Gram-negative strains lower than Gram-positive strains; in particular, S. epidermidis most sensitive (93.76%) compared equivalent concentration Ag. In case fungi, S4-7 exhibited better inhibitory negative control. highest dose (120 ppm) AgNP inhibited fungal growth being Alternaria (74.97%), followed Stemphylium (66.30%), Fusarium (45.62%), Rhizopus (32.68%). These findings highlight synthesized antimicrobial agents both pathogens.
