Crop productivity is severely affected by drought, and its incidence is predicted to enhance under environmental fluctuations and climate change throughout the world. Scarcity of water induced loss in crop growth as well as yields due to major changes in metabolic pathways and gene regulation. Innovative approaches using biochemical and molecular mechanisms increased our understanding of drought alleviation and its management. Previous researches have been focused on the alleviation of drought using rhizobacteria for sustainable agriculture. In recent years, drought stresses in the agriculture system have gained attention due to their deleterious impact on the crop production, protection, and soil health environment. Rhizobacteria perform an important role in the surface colonization of soil colloids and roots of the plant and facilitate proliferation in desired niche, while also improving soil fertility …
