“…Microbial communities function individually or in combination carrying out various beneficial activities and processes in the soil that improve soil fertility and enhance plant productivity (Prasad et al, 2017). In previous years, PGPR research has mainly focussed on the determination of the potentiality of a particular trait in specific bacteria, however, the focus of modern research is currently shifting towards the identification of beneficial microbial communities for rhizosphere engineering/manipulation and their implications for maintaining long‐term soil vigour (Hakim et al, 2021; Tsolakidou et al, 2019; Zhuang et al, 2021).…”

Plant rhizo-microbiome comprises complex microbial communities that colonize at the interphase of plant roots and soil. Plant growth-promoting rhizobacteria (PGPR) in the rhizosphere provide important ecosystem services ranging from the release of essential nutrients for enhancing soil quality and improving plant health to imparting protection to plants against rising biotic and abiotic stresses. Hence, PGPR serve as restoring agents to rejuvenate soil health and mediate plant fitness in the facet of changing climate. Though it is evident that nutrient availability in soil is managed through inter-linked mechanisms, how PGPR expedite these processes remain less recognized. Promising results of PGPR inoculation on plant growth are continually reported in controlled environmental conditions, however, their field application often fails due to competition with native microbiota and low colonization efficiency in roots. The development of highly efficient and smart bacterial synthetic communities by integrating bacterial ecological and genetic features provides better opportunities for successful inoculant formulations. This review provides an overview of the interplay between nutrient availability and disease suppression governed by rhizobacteria in soil followed by the role of synthetic bacterial communities in developing efficient microbial inoculants. Moreover, an outlook on the beneficial activities of rhizobacteria in modifying soil characteristics to sustainably boost agroecosystem functioning is also provided.

“…Rhizosphere microorganisms are important because they can manage nutrient transformation, nutrient acquisition and use, and crop sustainability ( Prasad et al, 2017 ). Rhizosphere microflora enhances the plant growth under abiotic stress through nitrogen fixation, plant hormone production, mineral solubilization, and iron carrier and HCN production.…”

Meloidogyne incognita is one of the most destructive soil pests, causing serious economic losses in tomato production. Here, in vitro experiments demonstrated that the Bacillus licheniformis strain JF-22 has the potential to prevent M. incognita infection. A pot experiment confirmed that B. licheniformis strain JF-22 isolated from the tomato rhizosphere soil and planted in the tomato root-knot nematode disease area effectively prevented and controlled M. incognita, reducing its negative effect on tomato growth. Additionally, the composition of volatile substances secreted by B. licheniformis strain JF-22 was analyzed using solid-phase microextraction and gas chromatography–mass spectrometry. We detected acetoin, 2,3-Butanediol, [R-(R*,R*) ]-, and hexamethyl cyclotrisiloxane as the main components among these volatiles. Using MiSeq sequencing technology and bioinformatics, we analyzed the influence of B. licheniformis strain JF-22 on the microbial community of the tomato rhizosphere. B. licheniformis strain JF-22 changed the composition of the microbial community; particularly, it significantly reduced the diversity of the fungal community. Furthermore, using the FUNGuild and PICRUSt databases, we predicted the effect of JF-22 on microbial community function. In conclusion, B. licheniformis strain JF-22 may be considered as a potential biocontrol agent against M. incognita.

“…Penicillium, Pseudomonas, Flavobacterium, Bacillus, Micrococcus, Fusarium, Aspergillus, and Sclerotium are P-solvent microbes [131] which can be isolated from cassava and sunflower skin waste which produce the fungi Aspergillus flavus, A. niger, Enterobacter, and Burkholderia [132,133]. Modification of rhizosphere through a combination of agronomy, nutrient management, use of organic and biological fertilizer, and regulation of rhizosphere processes can increase soil sustainability and nutrient efficiency [134].…”

Crops need nutrients to grow, develop, and produce yields, both in macro and micronutrients form. One of the essential macronutrients is phosphorus (P). Phosphorus is required by plants to produce plant biomass. Andisols are often used as agricultural lands in the highlands of the tropics. This soil type has high P retention and low available P. Andisol contains clay minerals with up to 97.8% P-retention. Therefore, this condition led to low P availability, but high total P in the soils. There was a tendency to increase the dose of inorganic fertilizers, especially P fertilizer in this area. A survey reported that shallot Andisol farmers applied P fertilizer about five times of shallot recommendation rate, however, the production has not increased, yet. The high rate of chemical fertilizers causes land degradation and environmental pollution. One of the solutions to increase phosphorus availability is by improving P solubility which increases P uptake by plants. Increasing P solubility is environmentally friendly and can be done by utilizing phosphate-solubilizing microbes which are often found in the plant rhizosphere. The use of phosphate-solubilizing microbes for plants today can be found in bio-fertilizers. This method could maintain soil health and give a good impact to the plant growth and production. This review would determine the use of phosphate-solubilizing microbes to manage P deficiency in Andisol soils. Some study cases about the effect of phosphate-solubilizing microbes on plant performances would also be addressed. Currently, it is hoped that farmers will begin to implement environmentally friendly agriculture by giving phosphate-solubilizing bio fertilizers to escalate available P and production.
