Alpha diversity measurements of bacterial (A) and fungal (B) communities for microbiome experiment. Bacterial alpha diversity was calculated using phylogenetic distance (PD) and Shannon index for both soil and rhizosphere grouped by treatment. Fungal alpha diversity was calculated using Shannon index and observed species in both soil and rhizosphere samples. Calculations of alpha diversity metrics were performed on OTU data rarefied to the minimum sample count, and statistical tests were done using a non-parametric one-way ANOVA with Dunn’s multiple comparison test to determine significant differences between treatment pairs. Crosses indicate the mean value within each treatment, while the middle line within the box indicates the median value. An asterisk indicates a significant difference compared to control treatment and tilde indicates a significant difference compared to −P control treatment (P < 0.05).
