Soil metagenomics reveals the effect of nitrogen on soil microbial communities and nitrogen-cycle functional genes in the rhizosphere of Panax ginseng

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: Aug. 7, 2024

Nitrogen (N) is the primary essential nutrient for ginseng growth, and a reasonable nitrogen application strategy vital maintaining stability of soil microbial functional communities. However, how microbial-mediated genes involved in cycling rhizosphere respond to addition largely unknown. In this study, metagenomic technology was used study effects different additions (N0: 0, N1: 20, N2: 40 N g/m

Metagenomic Insight into the Effect of Probiotics on Nitrogen Cycle in the Coilia nasus Aquaculture Pond Water

Microorganisms, Journal Year: 2024, Volume and Issue: 12(3), P. 627 - 627

Published: March 21, 2024

Recently, probiotics have been widely applied for the in situ remediation of aquatic water. Numerous studies proved that can regulate water quality by improving microbial community. Nitrogen cycling, induced microorganisms, is a crucial process maintaining balance ecosystem. Nevertheless, underlying mechanisms which enhance systems remain poorly understood. To explore indicators and their correlation with nitrogen cycling-related functional genes, metagenomic analysis element cycling was performed to identify genes Coilia nasus between control group (C) groups supplemented feed (PF) or (PW). The results showed adding could reduce concentrations ammonia (NH4+-N), nitrite (NO2−-N), total (TN) Community structure revealed relative abundance Verrucomicrobiota increased from 30 d 120 (2.61% 6.35%) PW group, while Cyanobacteria decreased (5.66% 1.77%).

Phosphorus Cycling Dominates Microbial Regulation of Synergistic Carbon, Nitrogen, and Phosphorus Gene Dynamics During Robinia pseudoacacia Restoration on the Loess Plateau

Agronomy, Journal Year: 2025, Volume and Issue: 15(4), P. 797 - 797

Published: March 24, 2025

Carbon (C), nitrogen (N), and phosphorus (P) are key soil nutrients whose synergistic interactions regulate ecosystem nutrient cycling, yet the functional gene-level coordination driving factors of these cycles remain poorly understood. This study addresses this gap by investigating dynamic changes in C, N, P cycling genes their microbial environmental drivers across Robinia pseudoacacia plantations different restoration stages (10, 20, 30, 40 years) on Loess Plateau. We analyzed physicochemical properties conducted metagenomic sequencing, redundancy analysis (RDA), Partial Least Squares Structural Equation Modeling (PLS-SEM). Results showed that P-cycling genes, particularly pqqC spoT, exhibited highest network centrality, indicating dominant role regulating dynamics. Compared with farmland, STC, SOC, SAP, pH, SWC significantly changed (p < 0.05) age, directly shaping groups such as Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi. These shifts were strongly correlated gene abundance 0.01). The findings highlight central phosphorus-solubilizing linking emphasize community responses to a driver during ecological restoration. provides novel insights into significance dynamics, offering theoretical support for improving strategies
