LEfSe Analysis of Phyllosphere Fungal Taxa in Leaf Samples from Different Regions
A KW sum-rank test was applied using the LEfSe algorithm to compare the distribution of OTUs between the leaves of rubber trees in different regions. These results revealed 11 OTUs that were exclusively distributed in BS, three OTUs that were exclusively distributed in DZ, 22 OTUs that were exclusively distributed in WN, and three OTUs that were exclusively distributed in WZS. Trichosphaeriales was the most abundant taxon in BS, Sporidiobolaceae was the most abundant taxon in DZ, both Dothideales and Dothioraceae were the most abundant taxa in WN, and Chaetomiaceae was the most abundant taxon in WZS (Figure 4). The plot cladogram results also revealed the community members that significantly influenced the delimitation of samples in different regions (Figure 5).
