Fig. 3

Log10 fold-change (mean ± SE) in absolute abundance of (A, B) 16S rRNA gene copies and metagenome functional genes (C, D) for the dominant Fe(III)-reducing bacterial taxon (A, C) Rhodoferax sp. and dominant Fe(II)-oxidizing bacterial taxon (B, D) Gallionella sp. compared to incubation sampling time point T0 within each soil layer microbiome. Absolute abundance values were derived from 16S rRNA amplicon sequencing and metagenome sequencing, respectively, relative to Thermus thermophilus internal standard recovered from each sequencing effort. An asterisk indicates a significant Log10 fold-change compared to incubation time point T0 within each soil layer microbiome (ANOVA; p < 0.05).
