“…Many studies based on plant–microbe interactions have deepened our understanding of microbial interactions in the context of promoting benefits and discovering the factors that shape microbial diversity [ 18 , 19 , 52 , 53 ]. Studies have pointed out that the microbial population is generally higher in the rhizosphere than in the soil due to the secretion of root exudates that contain secondary metabolites, which are energy sources for microorganisms [ 54 , 55 ].…”

“…Many studies have already shown that diazotrophic bacteria can promote plant growth and resilience to various environmental stresses [ 17 , 18 , 23 , 24 , 75 ]. However, few studies have described the genetic and biochemical mechanisms involved in promoting benefits to plants during bacterial interaction.…”

“…Remarkably, all of these bacterial species are gram-negative, except for the genus Bacillus , which has gram-positive representatives such as Bacillus subtilis . These endophytic and associative diazotrophic bacteria are considered plant growth–promoting rhizobacteria (PGPR), as they improve plant performance by enhancing the availability of nutrients and improve soil fertility, mainly through BNF and phosphate solubilization [ 17 , 18 , 19 ]. In addition, they produce plant growth regulators and are involved in the modulation of phytohormone and defense responses [ 20 , 21 , 22 ], production of antioxidants, osmotic adjustment, and plant tolerance against biotic and abiotic stresses [ 23 , 24 ].…”

Agriculture is facing increasing challenges with regard to achieving sustainable growth in productivity without negatively impacting the environment. The use of bioinoculants is emerging as a sustainable solution for agriculture, especially bioinoculants based on diazotrophic bacteria. Brazil is at the forefront of studies intended to identify beneficial diazotrophic bacteria, as well as in the molecular characterization of this association on both the bacterial and plant sides. Here we highlight the main advances in molecular studies to understand the benefits brought to plants by diazotrophic bacteria. Different molecular pathways in plants are regulated both genetically and epigenetically, providing better plant performance. Among them, we discuss the involvement of genes related to nitrogen metabolism, cell wall formation, antioxidant metabolism, and regulation of phytohormones that can coordinate plant responses to environmental factors. Another important aspect in this regard is how the plant recognizes the microorganism as beneficial. A better understanding of plant–bacteria–environment interactions can assist in the future formulation of more efficient bioinoculants, which could in turn contribute to more sustainable agriculture practices.

The coastal sand dune ecosystem at the Parangtritis Coast of Yogyakarta, Indonesia has unique characteristics such as low moisture sandy soil, high salinity and low nutrient content. Fimbristylis cymosa is one of the plant species having the capability to survive in that unique ecosystem. In this study, rhizobacteria isolated from the rhizosphere of F. cymosa were isolated to be further analyzed on their phosphate solubilizing and antagonistic properties against Fusarium oxysporum which cause the Wilt disease. The isolates of Phosphate Solubilizing Rhizobacteria (PSR) having the most potential capabilities were then polyphasically identified based on phenotypic and genotypic characters followed by 16S rDNA sequencing. The results showed that four PSR isolates (I8, I11, I12 and I24) have high phosphate dissolution indices. The highest indices were observed in isolates I11 (3.08) and I12 (3.44), respectively. Analysis of the dual plate experiments for PSR I11 and PSR I12 isolates against the growth of F. oxysporum also showed quite high inhibitory activities, i.e., isolate PSR I11 was 42.40%, while isolate PSR I12 was 42.08%. The two isolates were polyphasically identified as Burkholderia dolosa. This study clearly showed that PSR I11 and PSR I12 isolates are very potential and prospective to be used as marginal land inoculants and as providers of phosphorus. This study also showed that the isolates are useful as biocontrol agents against F. oxysporum in plants. Keywords: inhibitory activity, phosphate dissolution index, phosphorus, polyphasic identification, sandy soil
