Plant-associated microorganisms play an important role in agricultural production. Although various studies have shown that single can exert beneficial effects on plants, it is increasingly evident when a microbial consortium—two or more interacting microorganisms—is involved, additive synergistic results be expected. This occurs, part, due to the fact multiple species perform variety of tasks ecosystem like rhizosphere. Therefore, mechanisms plant growth stimulation (i.e., enhanced nutrient availability, phytohormone modulation, biocontrol, biotic and abiotic stress tolerance) exerted by different players within rhizosphere, such as plant-growth-promoting bacteria (PGPB) fungi (such Trichoderma Mycorrhizae), are reviewed. In addition, their interaction activity highlighted they act part consortium, mainly mixtures PGPB, PGPB–Mycorrhizae, PGPB–Trichoderma, under normal diverse conditions. Finally, we propose expansion use consortia, well increase research facilitate best most consistent field.
