Co-occurrence network of the fungal and bacterial communities associated with wheat root-zone soil in different treatments. a–d Fungal communities in control, FP, LFP, HFP treatments soil, respectively; e–h Bacterial communities in control, FP, LFP, HFP treatments soil, respectively. Different nodes are shown in different colors. Node size is proportional to the relative abundance; the larger node indicates the higher relative abundance. Links of different colors represent positive and negative interactions in the networks. Cyan respresents positive correlation, while red represents negative correlation
