Fig. 4: Microbial composition response to plant species richness and plant family composition treatments.

PCA plots showing (a) soil fungal composition response to plant species richness (p = 0.03, Table 2), (b) root bacteria composition response to plant family (p = 0.001, Table 2), soil bacteria composition response to the interaction of plant species richness and plant family (p = 0.02, Table 2), monocultures depicted in c and 6-species treatment shown in d. 2-species and 3-species interaction plots found in Supplementary Appendix Fig. 3. Root fungal saprobe composition differentiation in response to the interaction of planted species richness and plant family (p = 0.03, Table 2) shown in monoculture (e) and 6-species (f), with 2- and 3-species plots found in Supplementary Appendix Fig. 3. P-values reported are from PERMANOVA of microbial bray-curtis dissimilarity response to the model, as shown in detail in Table 2.
