The present study provides an insight into effects of physico-chemical endophytic bacterial community composition rhizosphere three different crops. Methods Musa basjoo Siebold L., Amygdalus persica Triticum aestivum L. were collected from inter-root soils plant roots to determine communities root system. Results results showed that resulted acidification, altered trace element content increased organic carbon. There was increase Ascomycota Actinobacteria phylum crop bacteria. Interestingly, chao1 shannon indices endophytes significantly elevated compared contro ( p < 0.05). Among them, highest level richness environment. environment functional enrichment histidine kinases oxidoreductases community. total potassium (TK) soil, as well Fe Pb content, positively correlated with α-diversity index Streptomyces .

Isolation and Functional Characterization of Endophytic Bacteria from Muscadine Grape Berries: A Microbial Treasure Trove

Cells, Год журнала: 2025, Номер 14(5), С. 369 - 369

Опубликована: Март 3, 2025

Muscadine grapes are renowned for their unique traits, natural disease resistance, and rich bioactive compounds. Despite extensive research on phytochemical properties, microbial communities, particularly endophytic bacteria, remain largely unexplored. These bacteria play crucial roles in plant health, stress tolerance, ecological interactions. This study represents the first comprehensive effort to isolate, identify, functionally characterize bacterial endophytes inhabiting muscadine grape berries using a culture-dependent approach. We isolated diverse species spanning six genera-Bacillus, Staphylococcus, Paenibacillus, Calidifontibacillus, Curtobacterium, Tatumella. Microscopic physiological analysis revealed variations morphology, with isolates demonstrating adaptability varied temperatures. Cluster-based indicated functional specialization among isolates, from Pseudomonadota Actinomycetota exhibiting superior growth-promoting abilities, whereas Bacillota displayed potential biocontrol probiotic properties. Among them, Tatumella ptyseos demonstrated exceptional including indole-3-acetic acid production, nitrogen fixation, phosphate solubilization, carbohydrate fermentation. Additionally, Bacillus spp. showed presumptive potential, while Paenibacillus cineris emerged as candidate. The identification of Calidifontibacillus erzurumensis novel further expands known biodiversity grape-associated microbes. findings provide insights into metabolic diversity endophytes, highlighting agricultural biotechnological applications.

Analysis of the Synergistic Effect of Endophytic Bacteria and Metabolites on Yield in Soybean Roots Under Biochar with Nitrogen Fertilization

Agronomy, Год журнала: 2025, Номер 15(1), С. 177 - 177

Опубликована: Янв. 13, 2025

The appropriate application of nitrogen fertilizers and biochar to the soil is beneficial for soybean growth, a combination can improve low-nitrogen fertilizer utilization efficiency. However, effect on roots still unclear. Therefore, in this study, we investigate changes endophytic bacterial communities metabolites under different combinations treatments by setting fertilization levels using high-throughput sequencing non-targeted metabolomics techniques. results showed that applying 20 t/ha 180 kg/ha (C2N1) resulted highest yield. By studying community roots, it was observed dominant phyla were Proteobacteria, Bacteroidota, Actinobacteriota, genera Bradyrhizobium, Streptomyces, Rhizobacter. Moreover, metabolic pathway analysis revealed glycosylphosphatidylinositol (GPI)-anchor biosynthesis most significant C0N1 vs. C0N0 comparison group, glycerophospholipid metabolism C2N1 C1N1 group; they both associated with regulatory mechanisms such as plant growth promotion nutrient cycling. Structural equation modeling indicates bacteria have positive impact Bradyrhizobium Rhizobium are observable variables effects bacteria, while Phe-Thr 7-allyloxycoumarin metabolites. Endophytic not only direct crop yield, but also indirectly affect yield through their This study has important scientific value guiding significance improving yields.

Local adaptation of plants to environmental conditions is gaining attention, particularly in the context climatic change and microbiota that are associated with it. It should be noted endophytes play a large role shaping plants. These microorganisms reside within plant tissues without causing any apparent harm their host. also highlighted an essential ecosystems by contributing health through multiple mechanisms. We suggest affect some animals, as they used ecological niche which animals thrive. Thus, we analyzed this aspect persistent but impermanent inhabitants various niches. Therefore, aim current review present knowledge (from last 10 years) on endophytes, applicability agriculture affecting animals. focused bioproducts biofertilizers containing indirectly connected agrobiotechnology, legal marketing these products, impact

Novel microbial technologies for optimizing maize plant–soil systems: the multifunctional strain Enterobacter sp. ES1

Pest Management Science, Год журнала: 2025, Номер unknown

Опубликована: Фев. 2, 2025

In recent years, a new microbial technology has emerged to optimize maize field productivity and soil health. This is crucial because of the adverse effects pesticide contamination diseases on yields. Enterobacter sp. ES1, multifunctional strain, effectively degraded 93.09% nicosulfuron within 4 days. Optimal degradation occurred at 35 °C pH 6.0, with 4% inoculum 20 mg L-1 nicosulfuron. Strain ES1 could fix nitrogen solubilize phosphorus potassium. It also detoxified potassium produced chrome azurol S indole-3-acetic acid. Moreover, it promoted rapid seed germination, induced resistance northern leaf blight, up-regulated genes ZmOPR2, ZmPR5, ZmHPL, ZmOX10, ZmPAL, ZmPR1, ZmAOS, ZmCTR1. ES1R-gfp, prepared using green fluorescent protein antibiotic domestication methods, functioned as bacterial fertilizer 31.04% sawdust, 32.96% straw, 12.15% biochar, exhibiting rate 99.65%. The novel strain was verified through pot experiment assessing concentration plant indices, thereby providing foundation for optimizing restoration. © 2025 Society Chemical Industry.

Introduction Constructed wetlands have become crucial ecosystems for the purification of industrial and agricultural water. The health wetland plants efficacy water are strongly influenced by root-associated bacteria. However, our understanding functions bacterial communities in plant different root components (i.e., rhizosphere, rhizoplane, endosphere) their impact on is still limited. Methods To address this knowledge gap, we employed high-resolution 16S rRNA deep amplicon sequencing to explore community structure assembly within three species (i.e. Iris ensata , Canna indica Hymenocallis littoralis ) found constructed wetlands. Results Our findings revealed that pollutant removal efficiency was higher wet season than dry season. specific compartment, species, environmental factors, seasonality significantly composition, diversity abundance. Across all Proteobacteria emerged as dominant groups components. abundance exhibited a decline from rhizosphere endosphere, accompanied an increase number distinctive biomarkers endosphere. composition significant similarity endosphere Bacterial genes rhizosphere-rhizoplane were associated with information processing, transportation metabolism, while those rhizoplane-endosphere primarily handle metabolic processes. positively correlated total nitrogen content, chemical oxygen demand, NO 4 + -N season, phosphorus, organic carbon, 3 content Discussion function can serve indicators
