Shifts in rhizosphere soil microorganisms of dominant plants' response to climate change profoundly impact mountain ecosystem multifunctionality; relatively little is known about the relationship between them and how they depend on long-term environmental drivers. Here, we conducted analyses microbial altitudinal pattern, community assembly, co-occurrence network 6 plants six typical vegetation zones ranging from 1350 2900 m (a.s.l.) Helan Mountains by absolute quantitative sequencing technology, finally related microbiomes root zone multifunctionality ('soil multifunctionality' hereafter), dependence was explored. It found that pattern bacterial fungal diversities differed significantly. Higher more potential interactions Stipa breviflora Carex coninux were at lowest highest altitudes. Bacterial α diversity, identity some taxa, had significant positive or negative effects multifunctionality. The effect sizes diversity greater than those effects. These results indicated balance microbes determines As number phylum level increases, there will be a net gain Our study reveals geographical climatic factors can directly modulate properties thereby affecting driving multifunctionality, points rather fungi being strongly associated with This work has important ecological implications for predicting multiple environment-plant-soil-microorganisms ecosystems respond future change.

Effects of organic fertilizers on plant growth and the rhizosphere microbiome

Applied and Environmental Microbiology, Journal Year: 2024, Volume and Issue: 90(2)

Published: Jan. 9, 2024

Application of organic fertilizers is an important strategy for sustainable agriculture. The biological source determines their specific functional characteristics, but few studies have systematically examined these functions or assessed health risk to soil ecology. To fill this gap, we analyzed 16S rRNA gene amplicon sequencing data from 637 samples amended with plant- and animal-derived (hereafter plant animal fertilizers). Results showed that increased the diversity microbiome, while maintained stability microbial community. Microcosm experiments verified were beneficial root development carbon cycle pathways, enriched nitrogen pathways. Compared fertilizers, harbored a lower abundance factors such as antibiotic resistance genes viruses. Consequently, might be more suitable long-term application in This work provides guide fertilizer selection perspective microecology promotes agriculture.IMPORTANCEThis study valuable guidance use agricultural production microbiome ecological risk.

Canopy nitrogen deposition enhances soil ecosystem multifunctionality in a temperate forest

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(3)

Published: March 1, 2024

Nitrogen (N) deposition affects ecosystem functions crucial to human health and well-being. However, the consequences of this scenario for soil multifunctionality (SMF) in forests are poorly understood. Here, we conducted a long-term field experiment temperate forest China, where N was simulated by adding above under canopies. We discover that canopy addition promotes SMF expression, whereas understory suppresses it. regulated fungal diversity treatments, which is largely due strong resistance acidification efficient resource utilization characteristics fungi. While bacterial diversity, mainly because resilience disturbances fast turnover bacteria. Furthermore, rare microbial taxa may play more important role maintenance SMF. This study provides first evidence enhanced enriches knowledge on affecting ecosystems. Given divergent results from two approaches, an innovative perspective diversity-multifunctionality relationships policy-making conservation sustainable management deposition. In future research, consideration processes essential realistic assessments effects atmospheric forests.

Biochar-based organic fertilizer application promotes the alleviation of tobacco (Nicotiana tabacum L.) continuous cropping obstacles by improving soil chemical properties and microbial community structure

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 1, 2025

Intensive monoculture poses a serious threat to agricultural sustainable development due the phenomenon of continuous cropping obstacles. Although organic amendment has been considered an efficient and environmentally friendly solution mitigate this tough issue, associated mechanisms remain poorly understood. Here, two-year field experiment was conducted with application four fertilizers, wood, rice straw, compound biochar-based fertilizers (WBF, RBF, CBF) chemical fertilizer (CF) under tobacco rotation broad bean oilseed rape, respectively. This work aims determine how BFs alleviates CCO further reveal underlying action primarily focusing on change soil micro-ecology environments. The results depicted that addition decreased morbidity (by 15.7–85.0%), heavy metals (Cd, V, Cu, Zn) contents in tobacco, improved leaf production yield 4.5–20.5%), economic value 14.6–34.4%) quality compared CF. Rhizosphere properties structure diversity microbial communities were enhanced treatments, reflecting growth bacterial OTUs number, alpha-diversity, abundances some beneficial genera (Arthrobacter, Pseudomonas, Gemmatimonas, Trichoderma, Mortierella, Penicillium, Chaetomium, etc.), reduction numbers detrimental microbes (Alternaria, Phytophthora nicotianae Fusarium oxysporum). Moreover, CBF stability complexity co-occurrence networks. Soil total carbon, structure, most important explanatory factors for increase value. Collectively, regime showed great potential as practical strategy alleviate by providing optimized environment.

Grazing‐induced enhancement of shrub ‘multifunctional island’ effect is associated with altered soil bacterial β diversity in shrub‐encroached grasslands

Journal of Applied Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Abstract The presence of shrubs improves ecosystem multifunctionality within their patches, an effect termed the ‘multifunctional island’ effect. However, mechanisms underlying and response to grazing are unclear. This study investigated how regulates these effects through a field experiment conducted on three paired grazed ungrazed sites shrub‐encroached grasslands in Inner Mongolia, China. analysis included 14 functional variables related plant productivity soil carbon, nitrogen phosphorus cycling. results indicated that significantly improved multifunctionality, thus creating pronounced varied with conditions was more under scenarios. Structural equation modelling directly increased shrub indirectly enhanced it changes bacterial β diversity, 51% variance being explained. Copiotrophic bacteria, notably Alphaproteobacteria , Gammaproteobacteria Actinobacteria known for accelerating nutrient cycling, played pivotal role mediating this Synthesis applications . Collectively, our provides robust evidence intensifies relative advantage advances understanding impact spatial variation biogeochemical cycling grasslands.
