Many strains of Pseudomonas fluorescens show potential for biological control of phytopathogens especially root pathogens. In taxonomic terms, several of them are indeed P. fluorescens sensu stricto, while others belong in fact to neighbouring species of the 'P. fluorescens' complex or to ill-defined related species within the fluorescent Pseudomonas spp. These bacteria have become prominent models for rhizosphere ecological studies and analysis of bacterial secondary metabolism, and in recent years knowledge on their plant-beneficial traits has been considerably enhanced by widening the focus beyond the case of phytopathogen-directed antagonism. Current genomic analyses of rhizosphere competence and biocontrol traits will likely lead to the development of novel tools for effective management of indigenous and inoculated P. fluorescens biocontrol agents and a better exploitation of their plant-beneficial properties for sustainable agriculture.
