  abstract  = "Pseudomonas fluorescens strain CHA0 is an effective biocontrol
               agent of various soilborne pathogens. It controls damping-off or
               root rot caused byPythium ultimum on cucumber, wheat and cress.
               Strain CHA0 synthesizes several antibiotic metabolites such as
               hydrogen cyanide, 2,4-diacetylphloroglucinol, and pyoluteorin.
               The role of pyoluteorin in the suppression of damping-off was
               investigated. Two Tn5 mutants (CHA660 and CHA661) of strain CHA0
               were isolated which had lost the capacity to produce pyoluteorin
               but still produced 2,4-diacteylphloroglucinol and HCN. These
               mutants still inhibitedP. ultimum on malt agar (which favours
               the production of 2,4-diacetylphloroglucinol) but had partially
               lost the ability to inhibit this pathogen on King's B agar
               (which favours the production of pyoluteorin). The two
               pyoluteorin-negative mutants showed a reduced capacity to
               suppress damping-off of cress caused byP. ultimum but were as
               effective in the protection of cucumber against this pathogen as
               the wild-type strain.These results indicate that, depending on
               the plant, pyoluteorin production plays a role in the
               suppression of damping-off by strain CHA0 without being a major
               mechanism in disease suppression. We suggest that the
               contribution of pyoluteorin to the biocontrol activity of strain
               CHA0 is determined by the quantity of this antibiotic produced
               in the rhizosphere, which might depend on the root exudates of
               the host plant.",
