The world's population has been rapidly increasing, as has the demand for basic essentials such as food. Today's agricultural need is increasing in yield while chemical fertilizers and pesticides, which are responsible for environmental deterioration, are being used less frequently. Due to many stresses that plants are subjected to today, a large portion of their yield has been lost. Due to their multifunctional plant protection and growth-related effects, agricultural manipulations of potentially beneficial rhizosphere microorganisms are quickly growing. Abiotic and biotic stresses are the two types of challenges that plants face. Plant Growth Promoting Rhizobacteria (PGPR) has exhibited both synergistic and antagonistic interactions with microorganisms in the surrounding environment to favorably improve plant growth. A highly specific communication system is used to regulate the direct and indirect effect. We attempted to cover all possible mechanisms of PGPR in this review article, as well as published studies for numerous ways that PGPR could be used to promote sustainable agriculture development through root system functioning and root architecture. PGPR impacts cell division, differentiation, root elongation, and development, resulting in increased root growth as well as improved shoot growth using number of ways, including the production of phytohormones such as cytokines, gibberellins, and auxins, as well as signaling that enhances overall plant development and health.
