Table 3 Summary of generalized linear models that modeled microbial ASV richness as a function of plant diversity, soil and leaf inoculation treatments. The models were fitted separately for soil fungi and bacteria. Abbreviation: Soil, soil inoculation; Leaf1, low-concentration leaf microbial inoculation and Leaf2, high-concentration leaf microbial inoculation (*p < 0.05; **p < 0.01; ***p < 0.001).
