Abstract
Pseudomonads enter into intimate associations with plants that can result in either plant growth promotion or cell death and disease. Two bacteria that exemplify these different interactions are the plant pathogen Pseudomonas syringae and the plant growth-promoting rhizobacterium (PGPR) P. fluorescens. P. syringae causes diseases of a wide range of plants and elicits a hypersensitive response (HR) in non-host plants. Plant growth-promoting P. fluorescens strains competitively colonise the plant rhizosphere, and have been shown to antagonise pathogenic microrganisms, synthesise phytohormones, and to elicit induced systemic resistance (ISR) in hosts.
