Multi-kingdom OTU networks in the bulk soil, rhizosphere soil and root. a Chord plots illustrating the distribution of correlations between high-level taxonomic groups and yield and rotation. The plot includes all correlations, i.e. does not distinguish between positive and negative correlations. Thickness of the ribbon indicates proportion of nodes within each group, which is shown on the outside circle. b Network functions of nodes (connected OTUs). Each node was assigned a role according to its topological properties. The within module degree measures how well-connected a node is to other nodes in the same module (y-axis). The among module connectivity measures how well-distributed the links of a node are among different modules (x-axis). Solid markers indicate the node was one of the 20 most abundant OTUs of their respective kingdom
