Agricultural soils suppressive to soilborne plant pathogens occur worldwide, and for several of these soils the biological basis of suppressiveness has been described. Two classical types of suppressiveness are known. General suppression owes its activity to the total microbial biomass in soil and is not transferable between soils. Specific suppression owes its activity to the effects of individual or select groups of microorganisms and is transferable. The microbial basis of specific…

Plants and Associated Soil Microbiota Cooperatively Suppress Plant-Parasitic Nematodes

Comprehensive understanding of the plant-beneficial microbial consortia and the mechanisms underlying disease suppression may help to develop synthetic microbial communities for biocontrol of PPN, thereby reducing nematicides and fertilizers inputs.

Pseudomonas and other Microbes in Disease-Suppressive Soils

Much is to be learned from disease-suppressive soils, where susceptible plants are protected from soil-borne pathogens by the indigenous microbiota, because these microbial interactions may be exploited to design sustainable crop protection strategies for ordinary farm soils.

Microbial and biochemical basis of a Fusarium wilt-suppressive soil

The microbial characterization of a Korean soil with specific suppressiveness to Fusarium wilt of strawberry is reported, highlighting the role of natural antibiotics as weapons in the microbial warfare in the rhizosphere that is integral to plant health, vigor and development.

Contribution of studies on suppressive soils to the identification of bacterial biocontrol agents and to the knowledge of their modes of action

Progresses in the knowledge of the microbial populations involved in the natural soil suppressiveness have allowed the isolation of biocontrol agents such as P. fluorescens, 2-79, Q8r1-96, C7 from soils naturally suppressive to black root rot, take-all and fusarium wilts, respectively.

Cropping of wheat in apple orchard soils prior to re-planting the site to apple provided control of the fungal pathogen Rhizoctonia solani AG-5 and examples suggest that management of resident plant-beneficial rhizobacteria may be a viable method for control of specific soilborne plant pathogens.

Current Insights into the Role of Rhizosphere Bacteria in Disease Suppressive Soils

The results of recent ‘omics’-based studies on the microbial basis of disease suppressive soils are reviewed, with specific emphasis on the role of rhizosphere bacteria in this intriguing microbiological phenomenon.

Climate change is likely to alter the distribution and severity of soilborne diseases affecting both intensive and low-input agricultural production systems. Naturally occurring disease suppressive

Development of fungal-mediated soil suppressiveness against Fusarium wilt disease via plant residue manipulation

This study investigated how the incorporation of pineapple residues in soils highly infested with the banana Fusarium wilt disease alleviates the pathogen pressure via changes in soil microbiomes and provides a successful example of how specific agricultural management strategies can be used to manipulate the soil microbiome towards the development of suppressive soils against economically important soil-borne diseases.

Deciphering the Rhizosphere Microbiome for Disease-Suppressive Bacteria

It is indicated that upon attack by a fungal root pathogen, plants can exploit microbial consortia from soil for protection against infections.

Microbial and volatile profiling of soils suppressive to Fusarium culmorum of wheat

This study screened a large collection of field soils for suppressiveness to Fusarium culmorum using wheat (Triticum aestivum) as a model host plant and revealed that volatile emission may contribute to suppression, but not for all suppressive soils.

It is shown that antibiotic production plays a significant role in both plant defense by and ecological competence of rhizobacteria in a well-documented induced suppression that occurs in response to the wheat root disease and continued monoculture of wheat.
