Abstract
Agriculture industry is facing dual pressure: overpopulation and abiotic stress. Among all the abiotic stresses, drought is one of the major limiting factors in crop losses. When plants are subjected to drought stresses, there are a series of events that lead to the accumulation of stress-responsive genes, chemical metabolites, and physiochemical malfunctioning of plants. However, the plants must defend themselves to survive. In addition, if the duration of the stress becomes longer, the plants might undergo reversible changes. Inoculation of microorganisms such as plant growth-promoting rhizobacteria as biostimulants is an emerging novel technique with promising effects. Plant–PGPR interaction provides a complex regulatory molecular network in biological systems to enhance the drought stress tolerance via the production of phytohormones, chemical metabolites, organic compounds, and ion homeostasis. This review chapter highlights the current knowledge about drought stress tolerance due to inoculation of PGPRs in maize crop plants.
