Fig. 2: Responsive fungal taxa.

Venn diagrams showing the number of fungal OTUs shared between CK with the CF, SOF, OF, SOF + T, and OF + T treatments or specific to each group (a). Cladogram showing phylogenetic relationships between 88 fungal OTUs (b). Leaf labels indicate representative sequence IDs. Rings, from the inner to the outside circles, represent (1) phylum-level taxonomy of OTUs; (2) shared and specific OTUs in CF treatment; (3) shared and specific OTUs in SOF treatment; (4) shared and specific OTUs in SOF + T treatment; (5) shared and specific OTUs in OF treatment; and (6) shared and specific OTUs in OF + T treatment. Bar graphs indicate the average number of potentially beneficial fungal OTUs in different treatments; linear regression relationship between the number of potentially beneficial fungal OTUs and cabbage yield (c). Bar graphs indicate the cumulative relative abundance of potentially beneficial fungal OTUs in different treatments; linear regression relationship between the cumulative relative abundance of potentially beneficial fungal OTUs and cabbage yield (d). CK control, CF chemical fertilizer treatment, SOF sterilized organic fertilizer treatment, OF organic fertilizer treatment, SOF + T T. guizhouense NJAU4742 inoculated sterilized organic fertilizer treatment; and OF + T: T. guizhouense NJAU4742 inoculated organic fertilizer treatment. Potentially beneficial fungal OTUs mean its relative abundance was significantly positively associated with yield.
