Classification of nodes (OTUs) to identify putative keystone OTUs within rhizosphere networks from tall (A) and semi-dwarf (B) cultivars. Node topologies are placed into four categories: module hubs (Zi > 2.5) are highly connected nodes within modules; connectors (Pi > 0.62) are nodes responsible for connecting modules; network hubs (Zi > 2.5 and Pi > 0.62) are highly connected nodes within the entire network and peripherals (Zi < 2.5 and Pi < 0.62) are nodes connected in modules with few outside connections. Bacterial co-occurrence networks from tall (C) and semi-dwarf (D) cultivars, calculated with sparCC, with correlations with a magnitude of > 0.7 or < −0.7. Each node (dot) represents an OTU and each colour indicates one respective phylum. The edges are represented by lines, with positive co-occurrence patterns between two nodes shown in blue and negative co-occurrence patterns shown in red.
