Pyoluteorin is a secondary metabolite produced by the biological control organism Pseudomonas fluorescens Pf-5, a rhizosphere bacterium. Pyoluteorin shows no toxicity to seed- and root-rotting plant pathogens. Pyoluteorin production is influenced by positive autoregulation. Addition of pyoluteorin to liquid cultures of Pf-5 enhanced pyoluteorin production.
Pyoluteorin functions as a signal molecule negatively regulating additional secondary metabolites produced by Pseudomonas [1]. The pyoluteorin contributes to the biological control of soilborne plant diseases by some strains of Pseudomonas fluorescens, including Pf-5. Pyoluteorin induces its own productionand represses the other’s production [2]. Depending on the plant, pyoluteorin production plays an important role in the suppression of damping-off by strain CHA0 without being a major mechanism in disease suppression [3].
