“…Samples treated with the inducer showed higher bacterial diversity hosting many groups of PGPBs such as Burkholderiaceae that might be linked to potassium (K) and phosphorous (P) solubilization and availability (Gu et al 2020); Pseudomonas and Bacillus spp. able to produce siderophores, auxin, cytokinins and characterized as phosphate-solubilizing bacteria (Saad et al 2020;Subrahmanyam et al 2020) (Table S7). These findings could explain the bacteriamediated growth effects in I treatments particularly for the SO4 genotype.…”

“…Within all microbes, fungi are also associated with the plants and in every plant, harbour has been symbiotically associated with particular fungi species, which fulfil the requirement of the host. In general, associated fungi are present in the three different plants regions (below and above ground) named as epiphytic or phyllosphere, endophytic and rhizosphere (Subrahmanyam et al 2020;Tiwari et al 2020;Yadav et al 2018a).…”

Microbes are ubiquitous in nature, and plant-microbe interactions are a key strategy for colonizing diverse habitats. Fungi are producing a wide range of secondary metabolites and bioactive compounds, which are probable alternative sources of drugs and/or antibiotics. Fungi are associated with the crops and plays an important role in plant growth promotion and enhanced soil fertility using different PGP mechanism such as solubilization of phosphorus, zinc, potassium; production of plant growth regulator (auxins, cytokinin, gibberellins, ethylene and abscisic acid); hydrolytic enzymes (xylanases, laccase, pectinases, cellulases); and siderophores. Besides eliciting plant defence reaction against pathogens; PGP fungi also help in plant growth promotion and alleviation of different abiotic stresses under harsh environments. The PGP fungi have reported from different genera of phyla Chytridiomycota, Zygomycota, Glomeromycota, Ascomycota, and Basidiomycota. Fungi also have significant potential applications in various industries like medical, and food. In the medical applications, fungi and fungal products are used to control disease in human and animals. In the fermentation industries fungi used to make alcoholic beverages, cheeses, bread, kefir, yogurt and various other food preparations and the agricultural sectors used to make plant healthy and protects to pathogens. The present review, deals with the biodiversity of beneficial fungi from different habitats and their biotechnological applications in plant growth promotion and soil health.

“…Additionally, Brevundimonas, Pedobacter, Luteoliobacter, Lacibacter, and Caenimonas have all been isolated from the root communities of different plants [42][43][44][45][46]. Lastly, Larkinella, Rhabdobacter and Sphingoaurantiacus are genera that have been previously isolated from organic amendments (Larkinella) or soil systems (Rhabdobacter and Sphingoaurantiacus) [47][48][49].…”

Soil microbiome disruption methods are regularly used to reduce populations of microbial pathogens, which often results in increase crop growth. However, little is known about the effect of soil microbiome disruption on non-pathogenic members within the soil microbiome. Here, we applied soil microbiome disruption, in the form of moist-heat sterilization (autoclaving) to reduce populations of naturally occurring soil microbiota. The disruption was applied to analyze bacterial community rearrangement mediated by four crops (corn, beet, lettuce, and tomato) grown in three historically distinct agroecosystem soils (conventional, organic, and diseased). Applying the soil disruption enhanced plant influence on bacterial colonization, and significantly different bacterial communities were detected between the tested crops. Furthermore, bacterial genera showed significant abundance increases both unique-to and shared-by each tested crop. As an example, corn uniquely promoted abundances of Pseudomonas and Sporocytophaga, regardless of the disrupted soil in which it was grown. Whereas the promotion of Bosea, Dyadobacter and Luteoliobacter was shared by all crops grown in all disrupted soils. In summary, soil disruption followed by crop introduction amplified plant-mediated selection of plant benefiting bacterial genera.
