Combined organic and inorganic fertilization can improve soil fertility in coal mine reclamation areas. However, the contribution of bacterial community (especially its occurrence patterns) to physicochemical properties enzyme activity needs further evaluation. The objective this research was clarify diversity, composition, intraspecific interactions response combined fertilizer application areas Loess Hilly Region, China. Maize rhizosphere samples were collected under four regimes (CK, no control; NPK, compound fertilizer; M, NPKM, fertilization) a 10-year field experiment Gujiao city, Shanxi Province. Bacterial communities characterized using high-throughput sequencing 16S rRNA gene V3–V4 region. A cross-treatment Spearman correlation network constructed explore co-occurrence patterns. Compared with CK, NPKM decreased pH by 0.59%, 2.27%, 0.12%; increased carbon 11.25%, 11.69%, 27.05%; significantly Shannon diversity 3.68%, 0.14%, 3.54%, respectively. sucrase, urease, alkaline phosphatase activities (p < 0.05). Critically, oligotrophic Acidobacteria more abundant CK than other treatments. Gemmatimonadetes NPK Actinobacteria, Bacteroidota, Patescibacteria NPKM. In addition, analysis revealed that keystone taxa different treatments belonged modules correlated nutrient content activity. Simultaneously, Actinobacteria enriched formed specific clusters through strong symbiosis, there significant positive correlations among phosphatase. summary, long-term improved maize regulating activity, species Region.

Endophytes from medicinal plants are potential biocontrol agents against Fusarium oxysporum f. sp. cubense (Foc), which is the causative fungus of banana wilt disease. In present study, endophytic bacterium was isolated Globba racemosa and their antagonistic activities Foc were studied, probable molecular mechanism antagonism predicted by docking studies. The 16SrRNA sequencing confirmed isolate to be Bacillus velezensis CBMB205 (EG2). isolates distortion fungal hyphae illustrated in SEM. metabolites identified FTIR, suggesting presence C-H, CH3 O-H groups. Two major such as β-amyrin dihydroxy octadecenoic acid (DA) LC-MS analysis. Molecular studies suggested that these showed binding with chitin synthase 1 1,3-glucan pathogenic fungi. energy (BE) interaction between synthase-1 (CS-1), (1,3-GS) estimated -10.17 kcal/mol − 9.5 kcal/mol, respectively. BE CS-1 1,3-GS determined -2.43 3.4 current study demonstrated EG2 towards provided a silico also provides insight into developing metabolite-based antifungal for various agricultural applications.

ABSTRACT Fungal seed‐ and soilborne diseases are economically devastating threats to global agriculture. The pathogenic fungi infiltrate seeds during production, storage, or planting persist within the soil, posing a significant challenge crop health yield. use of microbial consortia has become promising alternative for their management. In this study, 15 isolates (six fungal nine bacterial) were evaluated broad‐spectrum antagonistic activities against eight major pathogens, namely, Rhizoctonia solani (rice), Fusarium verticillioides (maize), Macrophomina phaseolina F . udum (redgram), oxysporum f. sp. ciceris (chickpea), Sclerotium rolfsii (groundnut), Aspergillus niger Alternaria sesami (sesame) under in vitro conditions. All showed variations inhibitory capabilities all pathogens. Evaluation plant growth‐promoting traits identified Trichoderma asperellum (Tricho1 Tricho2) Bacillus subtilis (B3, S4KB5 S8KB2) as most effective biocontrol isolates. three (MC1, MC2, MC3) developed using compatible potential reducing disease incidence promoting growth groundnut chickpea. consortium MC1 comprising Tricho1 + S8KB2 was both chickpea, which recorded lowest collar rot wilt 9.33% 8.33%, respectively. study consortia. These can be field conditions exploited biopesticides biofertilisers sustainable

Abstract Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations be alive, thus inhabiting ecosystems like salty ponds, marshes, or extremely lagoons. They more abundantly and widely distributed worldwide than initially expected. Most of them grouped into two families: Halobacteriaceae Haloferacaceae. The extreme conditions under which haloarchaea survive contribute their metabolic molecular adaptations, making good candidates for design bioremediation strategies treat brines, water, saline soils contaminated with toxic compounds such as nitrate, nitrite, oxychlorates perchlorate chlorate, heavy metals, hydrocarbons, aromatic compounds. New advances in understanding physiology, metabolism, biochemistry, biology suggest biochemical pathways related nitrogen carbon, can used proposals. This review analyses novelty most recent results showing capability some haloarchaeal species assimilate, modify, degrade living beings. Several examples role these treatment polluted brine also discussed connection circular economy-based processes. Key points • genuine metabolism metabolise highly beings These capabilities useful designing soil water

Soil health is crucial for global food production in the context of an ever-growing population. Microbiomes, a combination microorganisms and their activities, play pivotal role by biodegrading contaminants, maintaining soil structure, controlling nutrients' cycles, regulating plant responses to biotic abiotic stresses. Microbiome-based solutions along soil-plant continuum, scaling up from laboratory experiments field applications, hold promise enhancing agricultural sustainability harnessing power microbial consortia. Synthetic communities, i.e., selected consortia, are designed perform specific functions. In contrast, natural communities leverage indigenous populations that adapted local conditions, promoting ecosystem resilience, reducing reliance on external inputs. The identification indicators requires holistic approach. It fundamental current understanding status providing comprehensive assessment sustainable land management practices conservation efforts. Recent advancements molecular technologies, such as high-throughput sequencing, revealed incredible diversity microbiomes. On one hand, metagenomic sequencing allows characterization entire genetic composition microbiomes, examination functional potential ecological roles; other culturomics-based approaches metabolic fingerprinting offer complementary information snapshots activities both
