“…Soil-borne plant pathogens are hazardous to the plant growth and productivity (Gajbhiye et al, 2010). Most soil-borne pathogens survive in soil for long periods of time where they remain dormant until they find a suitable host (Vurro & Gressel, 2006). Some key pathogenic fungi are the species from the genus Fusarium .…”

Fungal pathogenic attacks are one of the major threats to the growth and productivity of crop plants. Currently, instead of synthetic fungicides, the use of plant growth-promoting bacterial endophytes has been considered intriguingly eco-friendly in nature. Here, we aimed to investigate the in vitro and in vivo antagonistic approach by using seed-borne endophytic Bacillus amyloliquefaciens RWL-1 against pathogenic Fusarium oxysporum f. sp. lycopersici. The results revealed significant suppression of pathogenic fungal growth by Bacillus amyloliquefaciens in vitro. Further to this, we inoculated tomato plants with RWL-1 and F. oxysporum f. sp. lycopersici in the root zone. The results showed that the growth attributes and biomass were significantly enhanced by endophytic-inoculation during disease incidence as compared to F. oxysporum f. sp. lycopersici infected plants. Under pathogenic infection, the RWL-1-applied plants showed increased amino acid metabolism of cell wall related (e.g., aspartic acid, glutamic acid, serine (Ser), and proline (Pro)) as compared to diseased plants. In case of endogenous phytohormones, significantly lower amount of jasmonic acid (JA) and higher amount of salicylic acid (SA) contents was recorded in RWL-1-treated diseased plants. The phytohormones regulation in disease incidences might be correlated with the ability of RWL-1 to produce organic acids (e.g., succinic acid, acetic acid, propionic acid, and citric acid) during the inoculation and infection of tomato plants. The current findings suggest that RWL-1 inoculation promoted and rescued plant growth by modulating defense hormones and regulating amino acids. This suggests that bacterial endophytes could be used for possible control of F. oxysporum f. sp. lycopersici in an eco-friendly way.

“…The soil‐borne pathogens can be controlled by chemicals, but these chemicals have several negative effects including damage to beneficial microbes, development of resistance in the pathogens, health risk to human beings, and environmental pollution . Chemical control of pathogens, particularly of sclerotial pathogens such as Sclerotinia sclerotium , Sclerotium rolfsii , Macrophomina phaseolina , Fusarium spp., Rhizoctonia solani and Pythium spp., diminishes the disease to some extent, but it is expensive and not eco‐friendly.…”

“…Chemical fungicides often have not a satisfactory effect on soil borne phytophathogenic fungi (Vurro and Gressel 2006). Also inputs of agrochemicals used for crop protection are adversely affecting the quality of food products and the environment, thus making the development of alternative ways to control disease a high priority (Lemanceau et al 1992).…”

Abstract:Siderophore production is an important mechanism of biological control by a number of strains of plant growth-promoting rhizobacteria. Pseudomonas fluorescens UTPF5 was originally obtained from onion field. Biochemical and physiological characteristics of this strain refer to biovar 3 of P. fluorescens. Strain UTPF5 is an effective bacterium against several phytopathogenic fungi. Pyoverdine type siderophore of this strain was isolated using XAD amberlite column. The plant growth promotion and antifungal properties of bacteria were demonstrated under greenhouse conditions in combination with Fe-EDTA, Fe-EDDHA and Zn as modulators of pyoverdine production. Amendment with zinc, Fe-EDTA and Fe-EDDHA suppressed the disease inhibition when partially used with UTPF5. 7NSK 2 and its pyoverdine mutant, MPFM1, were used as reference strains the inhibition percent of which was not affect by soil amendment. Iron chelates, especially Fe-EDDHA, increased growth and chlorophyll production by plants. This effect was improved in the presence of bacterial strains. The siderophore mutant MPFM1 did not exhibit satisfactory disease inhibition and growth promotion activity. In vitro experiments showed that purified pyoverdine could decrease the fungal growth to the same extent as pyoverdine-producing strain.
