Differentially abundant fungal ASVs. Fungal ASVs were identified whose abundance was affected by a) management (M), b-c) the rhizosphere effect (R), or d) the M × R interaction. The M × R interaction was strong in fungal communities, as shown by the high number of ASVs differing in abundance between the CR and OR environments. “Unknown” indicates that the ASV was not identified at the order level. Sample names on the x-axis indicate the combination of management system (C conventional, O organic), soil compartment (B bulk, R rhizosphere), and replicate (plot 1 = samples 1–3, plot 2 = samples 4–6, plot 3 = samples 7–9). Only ASVs that differed significantly among treatments at the α = 0.0125 level are shown
