Understanding the involvement of rhizobacteria-mediated induction of systemic resistance in biocontrol of plant diseases

Abstract
Specific strains of nonpathogenic rhizobacteria can induce systemic resistance that is effective against a range of plant pathogens. To exploit induced systemic resistance, detailed knowledge of the triggering bacterial traits involved and on signal transduction pathways in the plant is necessary. Possibilities to improve effectiveness of induced resistance by rhizobacterial strains are discussed.Key words: induced systemic resistance, lipopolysaccharides, Pseudomonas fluorescens, Pseudomonas putida, salicylic acid, siderophores, signaling pathways.
