The functional prediction of root microbiota. A and B Based on results of PICRUSt2 and FUNGuild, respectively. A Extended error bar plot of predicted metabolic pathways in bacterial microbiota. There were significant differences in 12 metabolic pathways in the functional abundance of bacterial microbiota from the two sites. Welch’s two-sided t-test and Bonferroni multiple test correction method were performed to test. B Heatmap for the composition of fungal functional group (guild) in fungal microbiota. The samples included A. vilmorinianum axial roots (AR), lateral roots (LR), and fibrous roots (FR)
