Relative read abundance of top FeOB and FeRB in plaque (with median relative abundance above 0.5%) over time for each biosphere. Abundance in bulk soil plotted with black solid line, rhizosphere plotted in tan short-dashed line, and plaque plotted in orange long-dashed line. Error bars show standard error. Asterisks indicate differential abundance in the plaque and bulk soil where adj. P < 0.1 based on DESeq2 analysis. Bulk 20 DPT n = 12, rhizosphere 20 DPT n = 12, plaque 20 DPT n = 3, bulk 42 DPT n = 11, rhizosphere 42 DPT n = 10, plaque 42 DPT n = 6, bulk 71 DPT n = 11, rhizosphere 71 DPT n = 11, plaque 71 DPT n = 4, bulk 88 DPT n = 12, rhizosphere 88 DPT n = 12, bulk 98 DPT n = 11, rhizosphere 98 DPT n = 11, and plaque 98 DPT n = 4.
