The global concern is population growth and rising food demands. It is unavoidable to implement new agricultural productivity-enhancing practices. Plant growth promoting rhizobacteria (PGPR) has showed promise as a sustainable agriculture approach. They have a critical function in increasing soil fertility, promoting plant growth, and suppressing phytopathogens in the development of environmentally friendly, long-term agriculture. Beneficial plant growth-promoting (PGPR) microorganisms can be used as effective biotechnological instruments to boost plant development in a variety of situations, including stressful ones. A rise in the occurrence of abiotic stresses, which have a negative impact on plant growth and productivity in major crops, has been seen all over the world. As a result of such stress elements, plant development will be reduced under stress conditions compared to non-stress ones. There is a growing global desire for effective, ecologically friendly methods to decrease the negative consequences of plant stress. The importance of plant-beneficial microbe interactions under such harsh conditions cannot be overstated. Plant growth promoting rhizobacteria (PGPRs) are a good option for reducing these stressors and are now routinely used. Plants inoculated with PGPRs undergo morphological and biochemical changes that lead to greater tolerance to abiotic stressors. In this review article we focus on PGPRs, abiotic stress effects on plant growth and PGPRs mechanism in alleviating salinity, drought and heavy metal stress condition for plant growth.
