Hierarchical Clustering Tree of Phyllosphere Fungal Samples from Different Regions
A hierarchical clustering tree was constructed based on a beta diversity distance matrix to compare similarities and differences among multiple samples (Figure 6). The results showed that the community composition of the WN_1, WN_2, and WN_3 samples was similar, and clustered into a single branch. The similarity between WZS_1 and WZS_2 was also high, and both DZ_1 and DZ_2 clustered together. Clearly, the similarity of the community composition of the WZS_CK, WN_CK, BS_CK, and DZ_CK samples was not high, and the similarity with the other three samples in the region was low, with significant differences.
