Genes, Год журнала: 2025, Номер 16(3), С. 285 - 285

Опубликована: Фев. 26, 2025

Background/Objectives:Maerua crassifolia, a threatened medicinal species endemic to drylands, exhibits pronounced drought sensitivity. Despite the critical role of microorganisms, particularly bacteria and fungi, microbial consortia in M. crassifolia’s rhizosphere remain underexplored. Methods: Metagenomic whole genome shotgun sequencing (WGS) was employed elucidate taxonomic composition bacterial fungal communities inhabiting soil crassifolia. Results: The data revealed marked predominance genomes relative communities, as evidenced by non-redundant gene analysis. Notably, arbuscular mycorrhizal fungi (AMF), specifically Rhizophagus clarus, irregularis Funneliformis geosporum, are key colonizers. This study confirmed presence phosphate-solubilizing (PSB), such Sphingomonas spp., Cyanobacteria Pseudomonadota, underscoring these microorganisms phosphorus cycle. Additionally, uncovered previously uncharacterized within phylum Actinobacteria, well unidentified taxa from Betaproteobacteria, Gemmatimonadota Chloroflexota phyla, which may represent novel with potential plant growth-promoting properties. Conclusions: Findings suggest complex, symbiotic network where AMF facilitate uptake through plant–root interactions. In tripartite symbiosis, PSB enhance inorganic solubilization, increasing bioavailability, assimilate deliver roots, optimizing nutrition. bacterial–fungal interplay is essential for resilience arid environments. Future investigations should prioritize isolation characterization underexplored residing particular emphasis on members phyla uncover their roles nutrient acquisition sustainability.

Abstract Highly saline soils negatively affect crop growth, especially rice. Although chemical approaches can be used, they damage the environment and sustainability of agriculture. Thus, a biological candidate should assessed. Therefore, study evaluated impact nitrogen (N)-fixing purple non-sulfur bacteria (PNSB) strains on improving soil properties, nutrient uptake, rice yield highly in My Xuyen district, Soc Trang province. The N-fixing PNSB were hypothesized to boost availability reduce salinity, leading greater growth yield. A pot experiment was arranged completely randomized block design with two factors, including four N applying rates (100, 75, 50, 0%) Rhodobacter sphaeroides (no added bacteria, single bacterial strain R. S01, S06, mixture S01 S06). results showed that adding mixed S06 improved plant height by 4.02–10.4% (the first season) 3.86–6.84% second season). Under application NH 4 + increased 31.8–50.5%, while Na decreased 16.0–25.7% both seasons. From there, total uptake also 34.9–73.8% went down 19.1–26.5% via This led traits, such as number panicles per pot, seeds panicle, filled seed rate Ultimately, grain 10.2–14.8% under greenhouse condition. In conclusion, current successfully provided potent N-fixer for improvements health. this liquid biofertilizer further tested field trails.

Growth-promoting effects of arbuscular mycorrhizal fungus Funneliformis mosseae in rice, sesame, sorghum, Egyptian pea and Mexican hat plant

Frontiers in Microbiology, Год журнала: 2025, Номер 16

Excessive use and overreliance on chemical fertilizers threatens soil health environmental sustainability, necessitating eco-friendly alternatives like arbuscular mycorrhizal fungi (AMF). The benefits of AMF are well-documented in staple crops, their effects diverse species-particularly legumes non-crop models under uniform conditions-remain underexplored, limiting scalable adoption. This study evaluated Funneliformis mosseae's role enhancing growth, nutrient uptake, stress resilience across five species: rice (Oryza sativa), sesame (Sesamum indicum), sorghum (Sorghum bicolor), Egyptian pea (Sesbania sesban), the Kalanchoe daigremontiana. pot-experiment was conducted natural open-field conditions (e.g., ambient light, temperature, humidity) inoculated plants were analyzed for biomass yield, concentrations, physiological parameters to evaluate F. efficacy as a sustainable growth promoter. Inoculation with mosseae significantly enhanced plant performance all species. Rice exhibited 43% increase dry biomass, alongside 53% higher phosphorus uptake 24.5% greater magnesium accumulation. Root development improved markedly, sesame, sorghum, pea, Mexican hat showing root length increases 66.7, 42.9, 35, 33.3%, respectively. Biomass gains consistent: (29% fresh 33% dry), (30% fresh, 39% (36.6% total), (31% 34% dry). Nutrient surged systemically, including potassium (sesame: 42%, pea: 17.8%), calcium 54.5%, sorghum: 29.4%), (Mexican plant: 32.4%, 22.5%). Physiologically, photosynthetic rates rose by 21.4-45% (highest pea), stomatal conductance 23.3-71.4% (peak sesame), chlorophyll b levels increased 30-39.1% 44.4-150.8%, respectively, These results suggested that could provide sustainable, environment friendly substitute fertilizers, preparing future agriculture, where ecological services such crop productivity fertility depend mycorrhizas conventional cultivation practices. Integrating into agricultural systems offers potential strategy farming practices viable secure long-term food security eco-sustainability.

Опубликована: Окт. 1, 2024

This study evaluated the impact of various doses (5, 10, 15 g) and application sequences (1, 2, or 3 times at monthly intervals) arbuscular mycorrhizal (AM) fungal inoculum on cardamom seedlings over two years (2020-2021 2021-2022). The results indicated that dosage AM had a more substantial effect than sequence. A 10 g dose significantly increased shoot length dry weight, while three applications 5 each improved number fibrous roots. Although potassium uptake was not affected, phosphorus calcium were highest with dose. Arbuscular inoculation also enhanced phosphatase activity in rhizosphere, improving acid alkaline activity. Disease incidence, including seedling rot lower dose, additional sequential did further reduce disease. Structural equation modeling (SEM) revealed colonization positively influenced weight through roots, showing strong relationship between colonization, spore count, dependency. indicates applying can be particularly beneficial agroecosystems for growth, nutrient uptake, disease resistance.

Abstract Coevolution within the plant holobiont extends capacity of host plants for nutrient acquisition and stress resistance. However, role rhizospheric microbiota in maintaining multinutrient utilization (i.e. traits) remains to be elucidated. Multinutrient cycling index (MNC), analogous widely used multifunctionality index, provides a straightforward interpretable measure traits plants. Using tomato as model plant, we characterized MNC (based on multiple aboveground contents) under different nitrogen water supply regimes explored associations between bacterial community assemblages profiles. Rhizosphere diversity, quantitative abundance, predicted function, key topological features co-occurrence network were more sensitive than supply. A core bacteriome comprising 61 genera, such Candidatus Koribacter Streptomyces, persisted across habitats served predictor uptake. The increased with greater diversity higher taxon abundance rhizobacterial community, while decreasing average degree graph density network. absorption by was primarily regulated complexity interaction water. high biodiversity complex species interactions play crucial roles performance. This study supports development rhizosphere microbiome engineering, facilitating effective manipulation enhanced benefits, which sustainable agricultural practices health.
