Sequencing and analysis data for leaf-amended PAH-contaminated soil bacterial–fungal microbiomes

This dataset supports a study investigating how graded leaf organic amendment regulates bacterial–fungal community structure, functional potential, cross-kingdom concordance, community assembly and resilience in PAH-contaminated soil microcosms. Treatments include control, PAH-only, and PAH-contaminated soils amended with 10%, 30%, and 70% leaf organic matter over a 56-day incubation. The archive contains raw or processed 16S rRNA V3–V4 and ITS1 amplicon sequencing data, sample metadata, ASV tables, taxonomic assignments, PAH-removal variables, ordination outputs, differential abundance results, co-occurrence network files, community assembly metrics, stability/resilience outputs, figures and analysis scripts.
