Phylogenetic relationships of orders with colors on the arc denoting the presence of orders within FON2 isolates samples. At the order level Pseudomonadles, unclassified proteobacteria, unclassified bacteria, Actinomycetales, Sphingobacteriales, and Burkholderiales were shared among all FON2 Isolates (A). At the OTU level ternary plot (B) visualizes a core bacterial strain associated equally among the three isolates in the center whereas the corners have a single dominant OTU with higher abundance showing a stronger correlation to their particular isolate. The heatmap (C) visualizes relative abundances of the core OTUs across all three generations of the three hyphospheres. A single OTU consistently dominates each hyphosphere (i.e. OTU002 with COM and OTU001 with HAR and OTU003 with W2)
