Alpha diversity and taxonomic composition of the fungal communities. a Sequence reads of the fungal communities (mean ± SEM, ^****p < 0.001, ^**p < 0.01). The dashed line indicates the depth of sequence rarefaction. b Alpha diversity of the fungal communities were calculated using four indices: Chao1 richness, Fisher’s alpha, Shannon’s diversity, and Shannon’s evenness (mean ± SEM, ^**p < 0.01, ^*p < 0.05, ns not significant)
