“…It is well-known that soil microbial communities are one of the most significant reservoirs of biological diversity in the world receiving no less than one quarter of the living organisms on earth ( Decaëns et al, 2006 , Tibbett et al, 2020 ). 17 different genera have been identified by this study, and the high genetic diversity is probably due to multitude elements ( Macdonald and Singh, 2014 , Nwachukwu and Babalola, 2021 ). PGPR are agriculture bioresources that enhance both plant growth and productivity, these Plant microbiomes have a direct impact on noxious microbes in the rhizosphere, and many beneficial microorganisms isolated from soil could boost the defensive capacity of the plant ( Zamioudis and Pieterse, 2012 , Babalola et al, 2021 ).…”

“…Furthermore, the main driver of bacterial communities close to the roots is recruitment from the bulk soil. However, even though some authors found differences in microbial communities between bulk and rhizosphere soil [ 37 ], others found a difference in both compartments with the phyllosphere [ 38 ]. In addition, diversity indices were found to be lower or higher in the rhizosphere compared with bulk soil [ 39 , 40 ].…”

Soil bacterial communities are involved in multiple ecosystem services, key in determining plant productivity. Crop domestication and intensive agricultural practices often disrupt species interactions with unknown consequences for rhizosphere microbiomes. This study evaluates whether variation in plant traits along a domestication gradient determines the composition of root-associated bacterial communities; and whether these changes are related to targeted plant traits (e.g., fruit traits) or are side effects of less-often-targeted traits (e.g., resistance) during crop breeding. For this purpose, 18 tomato varieties (wild and modern species) differing in fruit and resistance traits were grown in a field experiment, and their root-associated bacterial communities were characterised. Root-associated bacterial community composition was influenced by plant resistance traits and genotype relatedness. When only considering domesticated tomatoes, the effect of resistance on bacterial OTU composition increases, while the effect due to phylogenetic relatedness decreases. Furthermore, bacterial diversity positively correlated with plant resistance traits. These results suggest that resistance traits not selected during domestication are related to the capacity of tomato varieties to associate with different bacterial groups. Taken together, these results evidence the relationship between plant traits and bacterial communities, pointing out the potential of breeding to affect plant microbiomes.

“…Moreover, several bacteria like Myxobacter can produce a series of enzymes (chitinase, glucanase, lipase, and protease), which inhibit the growth of fungi in vitro [78]. Among the Gram‐negative bacteria that have chitinolytic activities are Serratia marcescens, Enterobacter agglomerans, Pseudomonas aeruginosa , and P. fluorescens are some of the Gram‐negative bacteria with chitinolytic abilities [79]. PGPR can also produce phosphatase which play an important role in the phosphate cycle and in soil biological activity [80].…”

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.
