Candidate driver co-occurrence networks of non-supplemented and iron-supplemented simples in the rhizosphere and bulk soil. Co-occurrence networks were constructed using only candidate driver nodes and the nodes to which they are connected in non-supplemented and iron-supplemented samples of rhizosphere soil A) and bulk soil B). Interactions were inferred from bacterial ASVs abundances. Each node represents ASVs annotated at the phylum level and edges represent positive (co-occurrence) or negative (exclusion) correlations between the relative abundances of the ASVs. Finally, the size of the nodes indicates whether the ASVs belong to abundant (relative abundance > 0.1) or rare (relative abundance < 0.1) abundance categories. Candidate driver nodes are identified by the word “Net”
