“…E. cloacae, the strain of interest in this study, is regarded as an endophytic symbiont of corn (Hinton and Bacon 1995). Several researchers reported the ability of E. cloacae to promote millets, rice, tomato, and mung bean in both normal and abiotic stress conditions (Pattnaik et al 2020;Sagar et al 2020;Mayak et al 2001). Interestingly, E. cloacae was also reported as a potential biocontrol agent against several pathogens, including Ralstonia solanacearum and Fusarium sambucinum (Mohamed et al 2020;Al-Mughrabi 2010).…”

Plant Growth Promoting Bacteria have proven themselves in agricultural applications not only as biofertilizers but also as biocontrol agents against different phytopathogens. In this study, we focused on investigating the ability of Enterobacter cloacae to induce the immune response of Zea mays against Fusarium oxysporum infection. The bacterium was transformed with a plasmid to express Green Fluorescence Protein and used in a greenhouse experiment in combination with Fusarium infection in different treatments. E. cloacae successfully colonized the root, resulting in enhanced physical growth with great investment in leaf area, photosynthetic pigment production, and reduced anthocyanin content. E. cloacae left a considerable resistance to root rot caused by Fusarium, as the disease severity was reduced from 74.2% (in the case of Fusarium infection alone) to about 35.8% (in the case of E. cloacae addition 14 days before fungal infection). The amount of salicylic acid (SA) was markedly elevated, and Pathogen-Related Protein showed up to an eightfold increase in the expression level. From these results, we suppose that E. cloacae induces SA-dependent systemic acquired resistance, which allows pre-colonized plants to resist Fusarium infection.

Soil saltiness is a noteworthy issue as it results in loss of profitability and development of agrarian harvests and decline in soil health. Microorganisms associated with plants contribute to their growth promotion and salinity tolerance by employing a multitude of macromolecules and pathways. Plant growth promoting rhizobacteria (PGPR) have an immediate impact on improving profitability based on higher crop yield. Some PGPR produce 1-aminocyclopropane-1-carboxylic (ACC) deaminase (EC 4.1.99.4), which controls ethylene production by diverting ACC into α-ketobutyrate and ammonia. ACC deaminase enhances germination rate and growth parameters of root and shoot in different harvests with and without salt stress. Arbuscular mycorrhizal fungi (AMF) show a symbiotic relationship with plants, which helps in efficient uptake of mineral nutrients and water by the plants and also provide protection to the plants against pathogens and various abiotic stresses. The dual inoculation of PGPR and AMF enhances nutrient uptake and productivity of several crops compared to a single inoculation in both normal and stressed environments. Positively interacting PGPR + AMF combination is an efficient and cost-effective recipe for improving plant tolerance against salinity stress, which can be an extremely useful approach for sustainable agriculture.
