Is it the rhizosphere a source of applicable multi-beneficial microorganisms for plant enhancement?

Abstract The plant faces different pedological and climatic challenges that influence its growth and their enhancement. While, plant-microbes interactions throught the rhizosphere offer several privileges to this hotspot in the service of plant, by attracting multi-beneficial mutualistic and symbiotic microorganisms plant growth-promoting rhizobacteria (PGPR), archaea, mycorrhizal fungi, endophytic fungi, and others…). Currently, numerous investigations showed the beneficial effects of these microbes on growth and plant health. Indeed, rhizospheric microorganisms offer to host plants the essential assimilable nutrients (phosphate solubilization, siderophores production...), stimulate the growth and development of host plants (phytohormones production, plant secondary metabolites induction…), and induce antibiotics production. They also attributed to host plants numerous phenotypes involved in the increase the resistance to abiotic and biotic stresses. The investigations and the studies on the rhizosphere can offer a way to find a biological and sustainable solution to confront these environmental problems. Therefore, interactions between microbes and plants may lead to interesting biotechnological applications on plant improvement and adaptation in different climates to obtain biological sustainable agricultures without the use of chemical fertilizers.
