In recent decades, drought has represented a major setback for the world's agricultural economy, causing substantial reductions in global agricultural production that threaten the amount of food and food security. Thus, are necessary new alternatives to improve the sustainability of agricultural yield, to cope with various stress factors, including drought and high temperatures. Beneficial microorganisms (fungi, rhizobacteria) play an important role in mitigating the stress caused by drought by modulating the enzymatic and non-enzymatic antioxidant systems of plants and by producing phytohormones, osmolytes which represent the primary mechanisms through which they mitigate the effects of water stress, improving plant growth parameters and soil characteristics. In this study, we presented a review of studies found in the literature regarding the currently known implications of beneficial microorganisms for drought tolerance, including their mechanisms of action and also implication of them in increase of soil fertility.
