The application of plant growth-promoting rhizobacteria (PGPR) in the field has been hampered by a number gaps knowledge mechanisms that improve growth, health, and production. These include (i) ability PGPR to colonize rhizosphere plants (ii) bacterial strains thrive under different environmental conditions. In this review, strategies host are summarized advantages having highly competitive discussed. Some exhibited recognition chemical signals nutrients from root exudates, antioxidant activities, biofilm production, motility, as well efficient evasion suppression immune system. Moreover, many contain secretion systems produce antimicrobial compounds, such antibiotics, volatile organic lytic enzymes enable them restrict growth potentially phytopathogenic microorganisms. Finally, compete successfully should be considered development bioinoculants.
