Fig. 2.

Venn diagrams of fungal operational taxonomic units (OTUs) in samples of a roots and shoot tips of banana plants adjacent to the wilting plants but without wilting symptoms (designated as Hroot and Htip, respectively) and shoot tips and roots of wilting banana plants (Wtip and Wroot); b pseudostems and roots of explants (Sstem and Sroot) and shoot tips and roots of healthy banana plants in fields without wilting symptoms (Btip and Broot); c Btip, Htip, Sroot, and Sstem. The Venn diagrams show the number of shared and unique OTUs in the samples. The different colored ovals represent different samples, and the intersections of the colored ovals indicate the coexisted bacterial OTUs in the samples
