Profile clustering network analyses depicting the impact of infestation with Fusarium oxysporum f. sp. cubense on the gammaproteobacterial microbiome of banana plants cultivated in Nicaragua (A) and Costa Rica (B). The relative abundances of OTUs at a dissimilarity level of 3% summarized at genus level with a mean read change between healthy and infested state of more than 0.5% of the data set were used. If the ratio of relative mean abundances exceeded 1.5, the taxa were regarded as altered and assigned to the respective profile. Only those taxonomic groups that featured the same pattern in at least two farms of the respective country are shown (grey connection lines: same pattern in two farms; black connection lines: same pattern in all three farms). Node sizes correspond to the abundance change between healthy and infested state; nodes matching to changes of 1%, 20% and 40% of the data set were added as reference points. Significant differences (p ≤ 0.05, Metastats) are indicated by red node borders.
