Synergistic interactions between Plant Growth Promoting Rhizobacteria (PGPR) and Arbuscular Mycorrhizal (AM) fungi have been increasingly recognized as crucial contributors to enhancing crop productivity and sustainability. PGPR and AM fungi form mutualistic relationships with plants, promoting nutrient uptake, enhancing stress tolerance, and stimulating growth. Their combined application has shown remarkable effects on various crops, including increased nutrient acquisition, improved water-use efficiency, and enhanced resistance to biotic and abiotic stresses. This review explores the mechanisms underlying the synergistic interactions between PGPR and AM fungi and their implications for sustainable agriculture for improving crop productivity and reducing the environmental impact of conventional agricultural practices.

“…PGPR utilized as bacterial formulations (Newton and McLellan, 2015) plays an important role in fixing atmospheric nitrogen (e.g., diazotrophs viz. Acetobacter, Azospirrillum), redeem nitrogen from ammonia (NH 4 ) and nitrate (NO 3 ) as well as increase accessibility of diverse nutrients such as iron, phosphorus, zinc, copper and cadmium through different groups of phosphate solubilizing bacteria (PSB), siderophore producing bacteria and arbuscular mycorrhizal fungi (AMF) (Gomathy et al, 2018). Several rhizobacteria viz.…”

Plant growth-promoting rhizobacteria (PGPR) are specialized bacterial communities inhabiting the root rhizosphere and the secretion of root exudates helps to, regulate the microbial dynamics and their interactions with the plants. These bacteria viz., Agrobacterium, Arthobacter, Azospirillum, Bacillus, Burkholderia, Flavobacterium, Pseudomonas, Rhizobium, etc., play important role in plant growth promotion. In addition, such symbiotic associations of PGPRs in the rhizospheric region also confer protection against several diseases caused by bacterial, fungal and viral pathogens. The biocontrol mechanism utilized by PGPR includes direct and indirect mechanisms direct PGPR mechanisms include the production of antibiotic, siderophore, and hydrolytic enzymes, competition for space and nutrients, and quorum sensing whereas, indirect mechanisms include rhizomicrobiome regulation via. secretion of root exudates, phytostimulation through the release of phytohormones viz., auxin, cytokinin, gibberellic acid, 1-aminocyclopropane-1-carboxylate and induction of systemic resistance through expression of antioxidant defense enzymes viz., phenylalanine ammonia lyase (PAL), peroxidase (PO), polyphenyloxidases (PPO), superoxide dismutase (SOD), chitinase and β-glucanases. For the suppression of plant diseases potent bio inoculants can be developed by modulating the rhizomicrobiome through rhizospheric engineering. In addition, understandings of different strategies to improve PGPR strains, their competence, colonization efficiency, persistence and its future implications should also be taken into consideration.

“…The mycelia of mycorrhizal fungi can extend several centimeters beyond the plant roots, forming a mycelial mesh that binds soil particles (Miller and Jastrow, 1992;Soka and Ritchie, 2014). The mycelia also produce a glue-like glycoprotein, glomalin, that functions as an adhesive that binds soil particles together thus reducing soil erosion (Gianinazzi et al, 2010;Singh, 2012;Gomathy et al, 2018;Prasad et al, 2018), while enhancing the structural integrity of the BSC community (Chaudhary et al, 2009).…”

Biological soil crusts (BSCs) consist of a diverse and highly integrated community of organisms that effectively colonize and collectively stabilize soil surfaces. BSCs vary in terms of soil chemistry and texture as well as the environmental parameters that combine to support unique combinations of organisms-including cyanobacteria dominated, lichen-dominated, and bryophyte-dominated crusts. The list of organismal groups that make up BSC communities in various and unique combinations include-free living, lichenized, and mycorrhizal fungi, chemoheterotrophic bacteria, cyanobacteria, diazotrophic bacteria and archaea, eukaryotic algae, and bryophytes. The various BSC organismal groups demonstrate several common characteristics including-desiccation and extreme temperature tolerance, production of various soil binding chemistries, a near exclusive dependency on asexual reproduction, a pattern of aerial dispersal over impressive distances, and a universal vulnerability to a wide range of human-related perturbations. With this publication, we provide literature-based insights as to how each organismal group contributes to the formation and maintenance of the structural and functional attributes of BSCs, how they reproduce, and how they are dispersed. We also emphasize the importance of effective application of molecular and microenvironment sampling and assessment tools in order to provide cogent and essential answers that will allow scientists and land managers to better understand and manage the biodiversity and functional relationships of soil crust communities.
