Wild rice has been demonstrated to possess enriched genetic diversity and multiple valuable traits involved in disease/pest resistance abiotic stress tolerance, which provides a potential resource for sustainable agriculture. However, unlike the plant compartments such as rhizosphere, structure assembly of phyllosphere microbial communities wild remain largely unexplored. Through amplicon sequencing, this study compared bacterial fungal its neighboring cultivated rice. The core taxa both are dominated with Pantoea, Methylobacterium, Nigrospora, Papiliotrema, potentially beneficial growth health. Compared rice, Sphingomonas, Phaeosphaeria, Khuskia were significantly phyllosphere. nitrogen-fixing Methylobacterium is wild-enriched microbe; Sphingomonas hub taxon networks. In addition, microbiota was more governed by deterministic complicated stable community network than Our list microbes reveals divergence between original habitats, highlights selective role recruiting specific microbiomes enhancing crop performance promoting food production.

Although pervasive microplastics (MPs) pollution in terrestrial ecosystems invites increasing concern, impact of MPs on soil microbial community assembly, and ecosystem functions multifunctionality received relatively little attention. Here, we manipulated a mesocosm experiment to investigate how polyethylene (PE MPs; 0, 1%, 5%, w/w) influence plant production, quality, diversity enzymology carbon (C), nitrogen (N) phosphorus (P) cycling, maize–soil continuum. Results showed that PE exerted negligible effect biomass (dry weight). The 5% caused declines the availability water, C P, whereas enhanced pH storage. activity C-cycling enzymes (α/β-1, 4-glucosidase, β-D-cellobiohydrolase) was promoted by 1% MPs, while β-1, 4-glucosidase inhibited MPs. reduced N-cycling (protease urease), increased P-cycling enzyme (alkaline phosphatase). shifted composition, number specialist species, stability networks resistance. altered with concentration decreasing dispersal limitation proportion (from 13.66 9.96%).

Soil microbes, the main driving force of terrestrial biogeochemical cycles, facilitate soil organic matter turnover. However, influence fauna on microbial communities remains poorly understood. We investigated microbiota dynamics by introducing competition and predation among into two ecosystems with different fertilization histories. The interactions significantly affected rare including bacteria fungi. Predation enhanced abundance C/N cycle-related genes. Rare are important drivers functional gene enrichment. Key taxa, SM1A02, Gammaproteobacteria, HSB_OF53-F07, were identified. Metabolomics analysis suggested that increased may be due to specific metabolic activity mediated interactions. had a stronger effect genes, metabolism compared competition. Long-term fertilizer application resistance animal These findings provide comprehensive understanding community under biological interactions, emphasizing roles in ecosystems.

Introduction Organic fertilizer offers significant advantages for sustainable agricultural development compared to inorganic fertilizers and is increasingly becoming the predominant strategy. Functional traits gut microbiota of soil fauna are recognized as potential indicators environmental changes.

Soil biota contribute substantially to multiple ecosystem functions that are key for geochemical cycles and plant performance. However, soil biodiversity is currently threatened by land-use intensification, a mechanistic understanding of how loss interacts with the myriad intensification elements (e.g., application chemical fertilizers) still unresolved. Here we experimentally simplified biological communities in microcosms test whether changes microbiome influenced multifunctionality including crop productivity (leek, Allium porrum). Additionally, half were fertilized further explore different levels interact nutrient additions. Our experimental manipulation achieved significant reduction alpha-diversity (45.9 % bacterial richness, 82.9 eukaryote richness) resulted complete removal taxa (i.e., arbuscular mycorrhizal fungi). community simplification led an overall decrease multifunctionality; particularly, retention capacity reduced biodiversity. Ecosystem was positively correlated (R = 0.79). Mineral fertilizer had little effect on compared reduction, but it leek nitrogen uptake from decomposing litter 38.8 %. This suggests natural processes organic acquisition impaired fertilization.
