Abstract :Drought and water stress are the major abiotic stresses that limit plant growth. Plant growth-promoting rhizobacteria, well known for their growth-promoting attributes, produce extracellular polysaccharides that form rhizosheaths around the roots, thereby protecting them from desiccation for a longer duration. Arbuscular mycorrhizae, one of the key determinants of soil quality, secrete glomalin protein, which shows soil aggregation properties and helps increase water stability, thereby overcoming drought conditions. Increasing extracellular polysaccharide products using plant growth-promoting rhizobacteria and mycorrhizal fungi density in the rhizospheric soil can be a means to improve the survival of plants during water stress periods. The present review highlights the role of microbes producing extracellular polysaccharides in maintaining soil health and plant growth under drought.
