The plant roots are invariably colonized by an extent of tiny microorganisms including arbuscular mycorrhizal fungi (AMF) which support plant health in multiple ways. The symbiotic relationship with host plants is achieved through various signaling mechanisms and metabolic pathways which guide their mutual survival. Besides their plant growth-promoting activities, they communicate with other soil microbes to improve plant fitness during unfavorable circumstances. Rhizobium and mycorrhization helper bacteria (MHB) interaction with AM fungi provides us with new insight for enhanced protection of plants against abiotic factors. In addition to that, the alteration of host nutrition, modifications in root physiology and morphology, increase plant defense. Thus, remodeling of the rhizospheric microbial community by AM fungi activates their multifaceted mechanisms in host plants against phytopathogens insect pests …
