“…This mechanism can be activated by certain nonpathogenic rhizospheric bacteria mainly through the presence of determinants inserted in their wall. They synthesize diffusible molecules that are perceived by the plant and induce a resistance mechanism [104]. Certain PGPR can activate the mechanisms of responses induced in the plant's resistance framework and lead the whole plant into an ISR state [105, 106].…”

General plant diseases as well as soil‐borne pathogens severely reduce agricultural yield. The rhizosphere (the region of the soil that includes and surrounds the roots) is an important niche for microbial diversity in particular phytobeneficial bacteria including plant growth‐promoting rhizobacteria (PGPR) which have been used for a very long time to combat plant diseases. Pathogen control and crop productivity can both be improved through the use of PGPR several mechanisms, including iron‐based nutrition, antibiotics, volatile substances, enzymes, biofilm, allelochemicals, and so on. Their modes of action and molecular mechanisms have improved our comprehension of how they are used to control crop disease. Therefore, there is a lot of literal information available regarding PGPR, but this review stands out since it starts with the fundamentals: the concept of the rhizosphere and the colonization process of the latter, particularly because it covers the most mechanisms. A broad figure is used to present the study's findings. The advantages of using PGPR as bioinoculants in sustainable agriculture are also mentioned.
