There was a total of 323,029 fungal community reads after filtering low-quality reads, chimaeras and trimming adapters, barcodes and primers. Four fungal phyla were present in the six samples (Fig. 2b). Ascomycota was the most dominant phylum, accounting for 99.45 to 99.98% of each sample’s reads, with an average relative abundance of 99.71%. The remaining phyla including the Basidiomycota, Chytridiomycota, and Zygomycota (Mucoromycota, Zoopagomycota) accounted for 0.29% of the remaining fungal reads. The genus-level relative abundance of the fungal communities is summarized in Table 1. Dominant fungal genera were similar among all samples. Among the ten most abundant fungal taxa, Fusarium and Aspergillus were present in all samples, and Fusarium was the most abundant genus across all samples, accounting for between 84.89% and 98.41% of the total community, with an average abundance of 93.53%. At the species level, F. oxysporum and F. solani were the dominant Fusarium species, and F. solani was the more abundant species of the two (Table 2).Table 1Relative abundance of dominant fungi among samples at the genus level.Dominant GenusNHI.1 (%)NHI.4 (%)NHI.8 (%)NHI.9 (%)NHI.11 (%)NHI.12 (%) Fusarium 96.8997.0792.3598.4084.9191.58 Candida 0.660.380000 Aspergillus 0.100.310.120.480.150.21 Wallemia 00.510000 Olpidiaster 0.31%00000 Meyerozyma 00.260.020.020<0.01 Acremonium 0.15<0.010<0.0100 Conocybe 0.1300000 Monascus 000.120.040.110.08 Monographella <0.01000.0600.10Table 2Relative abundance of dominant Fusarium species among samples.Dominant SpeciesNHI.1 (%)NHI.4 (%)NHI.8 (%)NHI.9 (%)NHI.11 (%)NHI.12 (%) Fusarium solani 92.8186.5792.3298.4084.8991.57 Fusarium oxysporum 4.0810.50<0.01<0.01<0.01<0.01
