Figure 1

Bipartite network of interactions between plant beneficial microbes (PBMs) and agricultural crops (from a total of 191 papers published between 1960 and 2019). Each colored line represents a specific association. In each case, the size of boxes is proportional to the number of interactions considered (a single study can include several interactions). Plant growth-promoting bacteria (PGPB) (blue), Trichoderma (green), rhizobia (red), arbuscular mycorrhizal (AM) fungi (yellow), and others [fungi (e.g., Aspergillus spp., Beauvaria bassiana) and the oomycete Pythium oligandrum] (purple). Percentages represent the proportion of interactions where the specific groups of PBM or plant species are participating.
