ABSTRACT The impact of the 2,4-diacetylphloroglucinol-producing biocontrol agent Pseudomonas fluorescens F113Rif on the diversity of the resident community of culturable fluorescent pseudomonads associated with the roots of field-grown sugar beet seedlings was evaluated. At 19 days after sowing, the seed inoculant F113Rif had replaced some of the resident culturable fluorescent pseudomonads at the rhizoplane but had no effect on the number of these bacteria in the rhizosphere. A total of 498 isolates of resident fluorescent pseudomonads were obtained and characterized by molecular means at the

Tryptose broth (TB) was inoculated with Listeria monocytogenes (strain Scott A or California), Pseudomonas aeruginosa, Pseudomonas flourescens, or a combination of L. monocytogenes plus Pseudomonas species, and incubated at 7 or 13°C for 8 weeks. McBride Listeria Agar was used to determine numbers of L. monocytogenes and Pseudomonas Isolation Agar to enumerate Pseudomonas species at 0, 7, 14, 28, 42, or 56 d. At 13°C, presence of P. fluorescens had a slight negative effect on growth of L. monocytogenes strain Scott A, and was somewhat detrimental to its survival during the extended incubation.

Several saprophytic fluorescent pseudomonads that are aggressive root colonizers express similar specific activities of superoxide dismutase during growth in liquid culture.

Abstract:
Pseudomonads producing the antimicrobial metabolite 2,4-diacetylphloroglucinol (Phl) can control soil-borne phytopathogens, but their impact on other plant-beneficial bacteria remains poorly documented. Here, the effects of synthetic Phl and Phl+ Pseudomonas fluorescens F113 on Azospirillum brasilense phytostimulators were investigated. Most A. brasilense strains were moderately sensitive to Phl. In vitro, Phl induced accumulation of carotenoids and poly-β-hydroxybutyrate-like granules, cytoplasmic membrane damage and growth inhibition in A. brasilense Cd. Experiments with P. fluorescens F113

Abstract:
The biological herbicide and antibiotic 4-formylaminooxyvinylglycine (FVG) was originally isolated from several rhizosphere-associated strains of Pseudomonas fluorescens. Biosynthesis of FVG is dependent on the gvg biosynthetic gene cluster in P. fluorescens. In this investigation, we used comparative genomics to identify strains with the genetic potential to produce FVG due to presence of a gvg gene cluster. These strains primarily belong to two groups of Pseudomonas, P. fluorescens and P. syringae, however, a few strains with the gvg cluster were found outside of Pseudomonas. Mass spectromet

During evolution, plants have become associated with guilds of plant-growth-promoting rhizobacteria (PGPR), which raises the possibility that individual PGPR populations may have developed mechanisms to cointeract with one another on plant roots. We hypothesize that this has resulted in signaling phenomena between different types of PGPR colonizing the same roots. Here, the objective was to determine whether the Pseudomonas secondary metabolite 2,4-diacetylphloroglucinol (DAPG) can act as a signal on Azospirillum PGPR and enhance the phytostimulation effects of the latter.
