Permafrost, characterized by its frozen soil, serves as a unique habitat for diverse microorganisms. Understanding these microbial communities is crucial predicting the response of permafrost ecosystems to climate change. However, large-scale evidence regarding stratigraphic variations in profiles remains limited. Here, we analyze community structure and functional potential based on 16S rRNA gene amplicon sequencing metagenomic data obtained from an ∼1000 km transect Tibetan Plateau. We find that alpha diversity declines but beta increases down soil profile. Microbial assemblages are primarily governed dispersal limitation drift, with importance drift decreasing increasing depth. Moreover, genes related reduction reactions (e.g., ferric iron reduction, dissimilatory nitrate denitrification) enriched subsurface layers. In addition, groups involved alternative electron accepting processes more contribute highly community-level metabolic layers, likely reflecting lower redox complicated trophic strategies microorganisms deeper soils. Overall, findings provide comprehensive insights into potentials regions.

Excessive use of antibiotics has caused the accumulation antibiotic resistance genes (ARGs) in soil environment, posing a great challenge to environmental safety and public health. However, there is lack comprehensive investigations ARGs profiles under different land utilization patterns, drivers that affect distribution remain poorly defined. Herein, we investigated eight uses explored critical factors influencing ARGs. The results showed abundance parks, residential areas, farmland, vegetable cultivation was significantly higher than other lands, with an average 2.08×103 copies/g dry soil. structural equation model demonstrated variables were pivotal dominated differences ARG across types (path coefficient=0.934), which physicochemical exhibited greatest contribution explanatory rate 20.27%, markedly heavy metal residues. Importantly, these manipulate succession microbial communities by altering connections between microorganisms, turn indirectly affects Moreover, exposure strongly correlated fertilizer application, precipitation, per capita water resources (p<0.01). Overall, this study provides well-rounded understanding land-use helps develop management strategies for curbing dissemination environment.
