“…These were potent fungicides (Przemieniecki et al 2019). Mohammed et al (2020) discerned that phosphate-solubilizing Pseudomonas fluorescens act as a biocontrol tool against tomato bacterial wilt causing organism Ralstonia solanacearum. These biocontrol agents produce lipases, proteases, and α-amylase enzymes that act against pathogens' metabolic machinery, and such bacterially treated plants displayed a low incidence of wilt and improved growth and development.…”

Phosphorus is the second most critical macronutrient after nitrogen required for metabolism, growth, and development of plants. Despite the abundance of phosphorus in both organic and inorganic forms in the soil, it is mostly unavailable for plant uptake due to its complexation with metal ions in the soil. The use of agrochemicals to satisfy the demand for phosphorus to improve crop yield has led to the deterioration of the ecosystem and soil health, as well as an imbalance in the soil microbiota. Consequently, there is a demand for an alternate cost-effective and eco-friendly strategy for the biofortification of phosphorus. One such strategy is the application of phosphate-solubilizing microorganisms which can solubilize insoluble phosphates in soil by different mechanisms like secretion of organic acids, enzyme production, and excretion of siderophores that can chelate the metal ions and form complexes, making phosphates available for plant uptake. These microbes not only solubilize phosphates but also promote plant growth and crop yield by producing plant-growth-promoting hormones like auxins, gibberellins, and cytokinins, antibiosis against pathogens, 1-aminocyclopropane-1-carboxylic acid deaminase which enhances plant growth under stress conditions, improving plant resistance to heavy metal toxicity, and so on. Pyrroloquinoline quinine (pqq) and glucose dehydrogenase (gcd) are the representative genes for phosphorus solubilization in microorganisms. The content presented in this review paper focuses on different mechanisms and modes of action of phosphate-solubilizing microorganisms, their contribution to phosphorus solubilization, growth-promoting attributes in plants, and the molecular aspects of phosphorus solubilization.

“…Therefore, recently, biological control by PGPR has been adopted on a commercial scale by using a number of experimental approaches. These microorganisms can be found in the rhizosphere, rhizoplane or in association with roots, which improve plant growth promotion in the absence of pathogens (direct mechanism) or reduce the deleterious effects of pathogens on crop yield (indirect mechanism) by antibiosis, HCN production, competition, induced systemic resistance and siderophore production (Shivakumar 2007 ; Mohammed et al 2020 ; Larkin 2020 ).…”

“…showed that Brevibacillus brevis GZDF3 (PGPR strain) isolated from the rhizosphere soil of Pinellia ternate could produce siderophores with strong antagonistic activity to Candida albicans . Also, P. aeruginosa and P. fluorescens strains could be used to develop active biocontrol agents of tomato bacterial wilt caused by Ralstonia solanacearum (Mohammed et al 2020 ).Similarly, Larkin ( 2020 ) suggested that bacterial inoculation with B. subtilis GB03 can be used as biocontrol against two strains of Rhizoctonia (Rhs1A1 and Bs69) under organic production practices over three field seasons.…”

Siderophore production by Bacillus subtilis MF497446 and Pseudomonas koreensis MG209738 and their efficacy in controlling Cephalosporium maydis in maize plant

Late wilt disease, caused by Cephalosporium maydis in maize plant, is one of the main economical diseases in Egypt. Therefore, to cope with this problem, we investigated the potentiality of plant growth promoting rhizobacteria in controlling this disease. Six strains (Bacillus subtilis, B. circulance, B. coagulanse, B. licheniformis, Pseudomonas fluroscence and P. koreensis) were screened for siderophore production, and using dual plate culture method and greenhouse experiment, antagonistic activity against C. maydis was studied. Using two superior strains, single and dual inoculation treatments in maize were applied in field experiment during the 2018 and 2019 seasons. Results indicated that B. subtilis and P. koreensis strains had shown the most qualitative and quantitative assays for siderophore production and antagonistic activities. In greenhouse, the most effective treatments on the pre-and post-emergence damping off as well as growth promotion of maize were T3 treatment (inoculated with B. subtilis), and T8 treatment (inoculated with P. koreensis). In field experiment, T5 treatment (inoculated with a mixture of B. subtilis and P. koreensis) showed significant increases in catalase (CAT), peroxidase (POX) and polyphenol oxidase (PPO) activities, as well as total chlorophyll and carotenoids than control treatments during the two growing seasons. In the same way, the highest effect in reducing infection and increasing the thickness of the sclerenchymatous sheath layer surrounding the vascular bundles in maize stem was observed and these results were a reflection of the increase in yield and yield parameters.

“…Beneficial microbes like Pseudomonas spp, Bacillus spp, Streptomyces sp and Tichoderma spp are continuously giving strong antagonistic potential, further antagonistic microbe would be developed as a bio-inoculant for plant growth and plant protection (Shanmugaiah et al, 2008; Shanmugaiah et al, 2015; Harikrishnan et al, 2016; Vaishnavi et al, 2019). Among different PGPR, fluorescent pseudomonads are significant groups of microbes in agricultural crop protection.Hence, the efficacy of FPs for the promotion of plant growth and the scope for biocontrol established by various researchers(Shanmugaiah et al, 2006;Zhou et al, 2012;Mohammed et al, 2020).…”

A total of 30 fluorescent pseudomonads (FPs) were showed significant antagonistic activity against different fungal phytopathogens with different level of the zone of inhibition (ZOI) for Rhizoctonia solani (5mm-34mm), Macrophomina phaseolina (9mm-37mm), Scleotium rolfsii (4mm-36mm), Helminthusporium solani (5mm-27mm), Fusarium oxysporum (2mm-25mm) and Fusarium oxysporum RACE (4mm-31mm) compared to control. The maximum growth of our selected isolate VSMKU4036 was observed in King'B Broth (KBB), pH 7.0 and at 37°C. The VSMKU4036 isolate has been recognized as Pseudomonas sp, based on the morphological, biological, and different functional characteristics. Antagonistic rhizobacterium Pseudomonas sp VSMKU4036 produced antimicrobial traits, such as plant growth promotion and various functional characters like siderophores, hydrogen cyanide (HCN), phosphate solubilization, indole acetic acid (IAA), biofilms formation, protease, gelatinase, amylase, and pectinase. Our superior biocontrol isolate VSMKU4036 was high resistance to tetracycline, streptomycin and nalidixic acid, however, it was sensitive to ampicillin and rifamycin. Pseudomonas sp VSMKU4036 showed maximum resistance to cadmium, nickel chloride, copper sulphate, magnesium sulphate, zinc chloride and ferric chloride where as highly sensitive to mercuric chloride, and selenium dioxide compared to control.
