Phe161 and Arg166 variants of p-hydroxybenzoate hydroxylase. Implications for NADPH recognition and structural stability. (1/912)

Phe161 and Arg166 of p-hydroxybenzoate hydroxylase from Pseudomonas fluorescens belong to a newly discovered sequence motif in flavoprotein hydroxylases with a putative dual function in FAD and NADPH binding [1]. To study their role in more detail, Phe161 and Arg166 were selectively changed by site-directed mutagenesis. F161A and F161G are catalytically competent enzymes having a rather poor affinity for NADPH. The catalytic properties of R166K are similar to those of the native enzyme. R166S and R166E show impaired NADPH binding and R166E has lost the ability to bind FAD. The crystal structure of substrate complexed F161A at 2.2 A is indistinguishable from the native enzyme, except for small changes at the site of mutation. The crystal structure of substrate complexed R166S at 2.0 A revealed that Arg166 is important for providing an intimate contact between the FAD binding domain and a long excursion of the substrate binding domain. It is proposed that this interaction is essential for structural stability and for the recognition of the pyrophosphate moiety of NADPH.  (+info)

Inhibition of vibrio anguillarum by Pseudomonas fluorescens AH2, a possible probiotic treatment of fish. (2/912)

To study the possible use of probiotics in fish farming, we evaluated the in vitro and in vivo antagonism of antibacterial strain Pseudomonas fluorescens strain AH2 against the fish-pathogenic bacterium Vibrio anguillarum. As iron is important in virulence and bacterial interactions, the effect of P. fluorescens AH2 was studied under iron-rich and iron-limited conditions. Sterile-filtered culture supernatants from iron-limited P. fluorescens AH2 inhibited the growth of V. anguillarum, whereas sterile-filtered supernatants from iron-replete cultures of P. fluorescens AH2 did not. P. fluorescens AH2 inhibited the growth of V. anguillarum during coculture, independently of the iron concentration, when the initial count of the antagonist was 100 to 1, 000 times greater that of the fish pathogen. These in vitro results were successfully repeated in vivo. A probiotic effect in vivo was tested by exposing rainbow trout (Oncorynchus mykiss Walbaum) to P. fluorescens AH2 at a density of 10(5) CFU/ml for 5 days before a challenge with V. anguillarum at 10(4) to 10(5) CFU/ml for 1 h. Some fish were also exposed to P. fluorescens AH2 at 10(7) CFU/ml during the 1-h infection. The combined probiotic treatment resulted in a 46% reduction of calculated accumulated mortality; accumulated mortality was 25% after 7 days at 12 degrees C in the probiotic-treated fish, whereas mortality was 47% in fish not treated with the probiont.  (+info)

Identification of the tliDEF ABC transporter specific for lipase in Pseudomonas fluorescens SIK W1. (3/912)

Pseudomonas fluorescens, a gram-negative psychrotrophic bacterium, secretes a thermostable lipase into the extracellular medium. In our previous study, the lipase of P. fluorescens SIK W1 was cloned and expressed in Escherichia coli, but it accumulated as inactive inclusion bodies. Amino acid sequence analysis of the lipase revealed a potential C-terminal targeting sequence recognized by the ATP-binding cassette (ABC) transporter. The genetic loci around the lipase gene were searched, and a secretory gene was identified. Nucleotide sequencing of an 8.5-kb DNA fragment revealed three components of the ABC transporter, tliD, tliE, and tliF, upstream of the lipase gene, tliA. In addition, genes encoding a protease and a protease inhibitor were located upstream of tliDEF. tliDEF showed high similarity to ABC transporters of Pseudomonas aeruginosa alkaline protease, Erwinia chrysanthemi protease, Serratia marcescens lipase, and Pseudomonas fluorescens CY091 protease. tliDEF and the lipase structural gene in a single operon were sufficient for E. coli cells to secrete the lipase. In addition, E. coli harboring the lipase gene secreted the lipase by complementation of tliDEF in a different plasmid. The ABC transporter of P. fluorescens was optimally functional at 20 and 25 degrees C, while the ABC transporter, aprD, aprE, and aprF, of P. aeruginosa secreted the lipase irrespective of temperature between 20 and 37 degrees C. These results demonstrated that the lipase is secreted by the P. fluorescens SIK W1 ABC transporter, which is organized as an operon with tliA, and that its secretory function is temperature dependent.  (+info)

Purification, characterization and gene cloning of 6-hydroxynicotinate 3-monooxygenase from Pseudomonas fluorescens TN5. (4/912)

6-Hydroxynicotinate 3-monooxygenase, a membrane-bound, 42-kDa monomeric enzyme from Pseudomonas fluorescens TN5 was purified and characterized. The enzyme catalyzes the oxidative decarboxylation of 6-hydroxynicotinate and depends on O2, NADH and FAD with the holoenzyme containing 1 M of FAD per 1 M of enzyme. The isolated enzyme was used for the synthesis of 2,5-dihydroxypyridine, a precursor for the chemical synthesis of 5-aminolevulinic acid, which is applied as a plant growth hormone, a herbicide and in cancer therapy. A 1.8-kbp DNA fragment, which contains the ORF encoding 6-hydroxynicotinic acid 3-monooxygenase, was cloned, sequenced and expressed in Escherichia coli. The deduced 385 amino acid sequence of the cloned ORF is in agreement with the enzyme molecular mass, amino acid sequence of an internal peptide, contains a putative FAD-binding site and is homologous to similar flavoproteins such as salicylate 1-monoxygenase.  (+info)

Characterization of the pyoluteorin biosynthetic gene cluster of Pseudomonas fluorescens Pf-5. (5/912)

Ten genes (plt) required for the biosynthesis of pyoluteorin, an antifungal compound composed of a bichlorinated pyrrole linked to a resorcinol moiety, were identified within a 24-kb genomic region of Pseudomonas fluorescens Pf-5. The deduced amino acid sequences of eight plt genes were similar to the amino acid sequences of genes with known biosynthetic functions, including type I polyketide synthases (pltB, pltC), an acyl coenzyme A (acyl-CoA) dehydrogenase (pltE), an acyl-CoA synthetase (pltF), a thioesterase (pltG), and three halogenases (pltA, pltD, and pltM). Insertions of the transposon Tn5 or Tn3-nice or a kanamycin resistance gene in each of these genes abolished pyoluteorin production by Pf-5. The presumed functions of the eight plt products are consistent with biochemical transformations involved in pyoluteorin biosynthesis from proline and acetate precursors. Isotope labeling studies demonstrated that proline is the primary precursor to the dichloropyrrole moiety of pyoluteorin. The deduced amino acid sequence of the product of another plt gene, pltR, is similar to those of members of the LysR family of transcriptional activators. pltR and pltM are transcribed divergently from the pltLABCDEFG gene cluster, and a sequence with the characteristics of a LysR binding site was identified within the 486-bp intergenic region separating pltRM from pltLABCDEFG. Transcription of the pyoluteorin biosynthesis genes pltB, pltE, and pltF, assessed with transcriptional fusions to an ice nucleation reporter gene, was significantly greater in Pf-5 than in a pltR mutant of Pf-5. Therefore, PltR is proposed to be a transcriptional activator of linked pyoluteorin biosynthesis genes.  (+info)

Promotion of antibiotic production by high ethanol, high NaCl concentration, or heat shock in Pseudomonas fluorescens S272. (6/912)

A stress imposed by a continuous feed of high ethanol, high NaCl concentration, or a high temperature shock increased antibiotic production by several times in Pseudomonas fluorescens S272. A tentative bioassay showed that the stress caused about 40-fold elevation in the autoinducer activity. Addition of synthetic autoinducers, N-(3-oxododecanoyl)-L-homoserine lactone or N-(3-oxohexanoyl)-L-homoserine lactone at a concentration of more than 100 micrograms/l to a non-stressed culture also increased the antibiotic production by several times. These results suggested that the antibiotic production in P. fluorescens S272 was regulated by N-acyl-homoserine lactone and the promotive effect by stress occurred through any function that increased the autoinducer production.  (+info)

Identification and characterization of a gene cluster for synthesis of the polyketide antibiotic 2,4-diacetylphloroglucinol from Pseudomonas fluorescens Q2-87. (8/912)

The polyketide metabolite 2,4-diacetylphloroglucinol (2,4-DAPG) is produced by many strains of fluorescent Pseudomonas spp. with biocontrol activity against soilborne fungal plant pathogens. Genes required for 2,4-DAPG synthesis by P. fluorescens Q2-87 are encoded by a 6.5-kb fragment of genomic DNA that can transfer production of 2,4-DAPG to 2,4-DAPG-nonproducing recipient Pseudomonas strains. In this study the nucleotide sequence was determined for the 6.5-kb fragment and flanking regions of genomic DNA from strain Q2-87. Six open reading frames were identified, four of which (phlACBD) comprise an operon that includes a set of three genes (phlACB) conserved between eubacteria and archaebacteria and a gene (phlD) encoding a polyketide synthase with homology to chalcone and stilbene synthases from plants. The biosynthetic operon is flanked on either side by phlE and phlF, which code respectively for putative efflux and regulatory (repressor) proteins. Expression in Escherichia coli of phlA, phlC, phlB, and phlD, individually or in combination, identified a novel polyketide biosynthetic pathway in which PhlD is responsible for the production of monoacetylphloroglucinol (MAPG). PhlA, PhlC, and PhlB are necessary to convert MAPG to 2,4-DAPG, and they also may function in the synthesis of MAPG.  (+info)

The main effects of antagonistic rhizobacteria on plant pathogenic fungi are antibiosis, fungistasis or an indirect constraint through the induction of a plant defence response. To explore different biocontrol mechanisms, an in vitro confrontation assay was conducted with the rhizobacterium Pseudomonas fluorescens Pf29Arp as a biocontrol agent of the fungus Gaeumannomyces graminis var. tritici (Ggt) on wheat roots. In parallel with the assessment of disease extension, together with the bacterial and fungal root colonization rates, the transcript levels of candidate fungal pathogenicity and plant-induced genes were monitored during the 10-day infection process. The bacterial inoculation of wheat roots with the Pf29Arp strain reduced the development of Ggt-induced disease expressed as attack frequency and necrosis length. The growth rates of Ggt and Pf29Arp, monitored through quantitative polymerase chain reaction of DNA amounts with a part of the Ggt 18S rDNA gene and a specific Pf29Arp strain detection

DING proteins constitute a conserved and broadly distributed set of proteins found in bacteria, fungi, plants and animals (including humans). Characterization of DING proteins from animal and plant tissues indicated ligand-binding ability suggesting a role for DING proteins in cell signaling and biomineralization. Surprisingly, the genes encoding DING proteins in eukaryotes have not been identified in the eukaryotic genome or EST databases. Recent discovery of a DING homologue (named Psp here) in the genome of Pseudomonas fluorescens SBW25 provided a unique opportunity to investigate the physiological roles of DING proteins. P. fluorescens SBW25 is a model bacterium that can efficiently colonize plant surfaces and enhance plant health. In this report we genetically characterize Psp with a focus on conditions under which psp is expressed and the protein exported. Psp is closely related to the periplasmic Pi binding component of the ABC-type phosphate transporter system (Pst). psp is flanked by a gene

Pseudomonas fluorescens SBW25 was tagged with a triple marker gene cassette containing gfp, encoding green fluorescent protein; luxAB, encoding luciferase; and telABkilA, encoding tellurite resistance, and the tagged strain was monitored in the first Swedish field release of a genetically modified microorganism (GMM). The cells were inoculated onto winter wheat seeds and the GMM cells (SBW25∷tgl) were monitored in the field from September 2005 to May 2006 using plating, luminometry and microscopic analyses. Cell numbers were high on all sampling occasions and metabolically active cells were detected on all plant parts. Field results were similar to those obtained in a parallel phytotron study, although the amount of SBW25∷tgl detected on shoots was significantly higher in the phytotron than in the field. After winter, cell counts were 100-fold higher on the roots and root-associated soil compared with prewinter measurements, although the cells had a lower relative metabolic activity. ...
Pseudomonas fluorescens is a specific spoilage microorganism of refrigerated marine fish, and is highly adapted to low temperature. Cold shock proteins (CSPs) play an important role in cold adaptation of bacteria. In this study, CSP genes were identified from the genome of P. fluorescens PF08 by search of the conserved domain of CSPs with HMMER software, and the CSP physicochemical properties, structures, and functions were analyzed through bioinformatics. Five typical CSPs were identified in the P. fluorescens PF08 genome (PfCSPs). All five PfCSPs are small hydrophilic acidic proteins with a molecular mass of ca. 7.4 kDa. They are located in the cytoplasm and are nonsecretory and nontransmembrane proteins. Multiple sequence alignment analysis indicated that the CSPs are highly conserved between species, especially in DNA-binding sites and RNA-binding motifs that can bind to single-stranded DNA and RNA. The five PfCSPs clustered with CspD from Escherichia coli and Salmonella Typhimurium, which ...

The primary aim of this study was to investigate the effects of seed inoculation with the biocontrol agent Pseudomonas fluorescens strain F113 (producing the antibiotic DAPG) and its modified derivative strain F113G22 (with DAPG production disrupted) on the uptake of nitrogen by pea and wheat plants. Uptake of N by the two plant species was investigated in soil microcosms amended with 15N-labelled fertilisers (urea or ammonium nitrate) or 15N-labelled plant residues. Uptake of fertiliser-N was unaffected by inoculation. However, uptake of N derived from organic residues was enhanced in pea inoculated with either strain. In contrast, uptake of N by wheat was reduced in the presence of either strain F113 or F113G22, suggesting that the effects of these microbial inocula on N-mineralisation in the rhizosphere were dependent on plant species. It was subsequently found that microfaunal populations, especially soil nematodes in the rhizosphere of inoculated pea were significantly larger than those ...
Pseudomonas fluorescens BRG100 produces secondary metabolites with herbicidal activity to the grass weeds wild oat, Avena fatua, and green foxtail, Setaria viridis. The green fluorescence protein (gfp) gene was introduced into P. fluorescens BRG100 from Escherichia coli S17-1¥ë via a Tn5 mini transposon suicide vector system. Colony morphology, growth rate in liquid media, weed biocontrol efficacy (plant growth pouch), carbon utilization (Biolog GN) and root colonization of green foxtail by several P. fluorescens BRG100gfp transformants were determined to be the same as the wild type. Pseudomonas fluorescens BRGgfp-15 was found to be most similar to the wild-type in all of the above characteristics and was thus used in subsequent experiments. Note: all strains of Pseudomonas fluorescens will be referred to by only their strain throughout (ie. BRGgfp-15 and BRG100). It was determined by population dynamics per section of root with spiral plating on culture medium, epi-fluorescence and confocal ...

Recent studies suggest that bacteria are able to sense and respond to the presence of neighbouring bacteria in the environment and alter their response accordingly. This ability might be an important strategy in complex habitats such as soils, with great implications for shaping the microbial community structure. Here, we used a sand microcosm approach toinvestigate how Pseudomonas fluorescens Pf0-1 responds to the presence of monocultures or mixtures of two phylogenetically different bacteria, a Gram-negative (Pedobacter sp.

In this study we show that RpoN is required for efficient colonization of sugar beet seedlings by the plant growth-promoting bacterium Pseudomonas fluorescens SBW25, and use phenotypic and bioinformatic approaches to profile the RpoN-dependent traits and genes of P. fluorescens SBW25. RpoN is required for flagellar biosynthesis and for assimilation of a wide variety of nutrient sources including inorganic nitrogen, amino acids, sugar alcohols and dicarboxylic acids. Chemosensitivity assays indicate that RpoN-regulated genes contribute to acid tolerance and resistance to some antibiotics, including tetracyclines and aminoglycosides. Gain of function changes associated with loss of RpoN included increased tolerance to hydroxyurea and Guanazole. Bioinformatic predictions of RpoN-regulated genes show a close correspondence with phenotypic analyses of RpoN-regulated traits and suggest novel

Pseudomonas fluorescens ATCC 17400 also displays a strong in vitro antagonism against the Oomycete Pythium, which is repressed by iron, suggesting the involvement of a siderophore(s). While a pyoverdine-negative mutant retains most of its antagonism, a thioquinolobactin-negative mutant only slowed-down Pythium growth, and a double pyoverdine-, thioquinolobactin-negative mutant, which does not produce any siderophore, totally lost its ...

Many micro-organisms exist in natural habitats that are subject to severe or dramatically fluctuating environmental conditions. Such is the case for bacteria inhabiting plant surfaces, where they are exposed to UV irradiation, oxygen radicals, and large fluctuations in temperature and moisture. This study focuses on the role of RpoS, a central regulator of stationary-phase gene expression in bacterial cells, in stress response and environmental fitness of Pseudomonas fluorescens Pf-5. Strain Pf-5 is a rhizosphere-inhabiting bacterium that suppresses plant diseases caused by several plant-pathogenic fungi and oomycetes. Previous studies demonstrated that rpoS was required for osmotic and oxidative stress resistance of Pf-5. The results of this study demonstrate a role for rpoS in tolerance of Pf-5 to freezing, starvation, UV irradiation and desiccation stress. In field studies, an rpoS mutant was compromised in rhizosphere colonization of plants in dry soil, whereas similar rhizosphere populations were

Biotin (vitamin H or vitamin B7) is the essential cofactor of biotin-dependent carboxylases, such as pyruvate carboxylase and acetyl-CoA carboxylase. Mammals cannot synthesize biotin, while in bacteria, fungi, and plants it is synthesized from pimelate thioester through different pathways. In E. coli and many organisms, pimelate thioester is derived from malonyl-ACP. The pathway starts with the methylation to malonyl-ACP methyl ester, followed by the fatty acid chain elongation cycle to form pimeloyl-ACP methyl ester, which is then demethylated to form pimeloyl-ACP [MD:M00572]. Pimeloyl-ACP is converted to biotin through the final four steps in the biotin bicyclic ring assembly, which are conserved among biotin-producing organisms [MD:M00123]. In B. subtilis, biotin is derived from pimeloyl-ACP formed by oxidative cleavage of long-chain acyl-ACPs [MD:M00573]. Some bacteria synthesize biotin from pimeloyl-CoA derived from pimelate [MD:M00577]. Biotin is covalently attached to biotin-dependent ...
The transcriptional regulator AmrZ is a global regulatory protein conserved within the pseudomonads. AmrZ can act both as a positive and a negative regulator of gene expression, controlling many genes implicated in environmental adaption. Regulated traits include motility, iron homeostasis, exopolysaccharides production and the ability to form biofilms. In Pseudomonas fluorescens F113, an amrZ mutant presents a pleiotropic phenotype, showing increased swimming motility, decreased biofilm formation and very limited ability for competitive colonization of rhizosphere, its natural habitat. It also shows different colony morphology and binding of the dye Congo Red. The amrZ mutant presents severely reduced levels of the messenger molecule cyclic-di-GMP (c-di-GMP), which is consistent with the motility and biofilm formation phenotypes. Most of the genes encoding proteins with diguanylate cyclase (DGCs) or phosphodiesterase (PDEs) domains, implicated in c-di-GMP turnover in this bacterium, appear to ...
The genomic sequence of Pseudomonas fluorescens F113 has shown the presence of a 41 kb cluster of genes that encode the production of a second flagellar apparatus. Among 2535 pseudomonads strains with sequenced genomes, these genes are only present in the genomes of F113 and other six strains, all but one belonging to the P. fluorescens cluster of species, in the form of a genetic island. The genes are homologous to the flagellar genes of the soil bacterium Azotobacter vinelandii. Regulation of these genes is mediated by the flhDC master operon, instead of the typical regulation in pseudomonads, which is through fleQ. Under laboratory conditions, F113 does not produce this flagellum and the flhDC operon is not expressed. However, ectopic expression of the flhDC operon is enough for its production, resulting in a hypermotile strain. This flagellum is also produced under laboratory conditions by the kinB and algU mutants. Genetic analysis has shown that kinB strongly represses the expression of the flhDC

The GGDEF response regulator WspR couples the chemosensory Wsp pathway to the overproduction of acetylated cellulose and cell attachment in the Pseudomonas fluorescens SBW25 wrinkly spreader (WS) genotype. Here, it is shown that WspR is a diguanylate cyclase (DGC), and that DGC activity is elevated in the WS genotype compared to that in the ancestral smooth (SM) genotype. A structure-function analysis of 120 wspR mutant alleles was employed to gain insight into the regulation and activity of WspR. Firstly, 44 random and defined pentapeptide insertions were produced in WspR, and the effects determined using assays based on colony morphology, attachment to surfaces and cellulose production. The effects of mutations within WspR were interpreted using a homology model, based on the crystal structure of Caulobacter crescentus PleD. Mutational analyses indicated that WspR activation occurs as a result of disruption of the interdomain interface, leading to the release of effector-domain repression by the N
Rhizoremediation of organic chemicals requires high-level expression of biodegradation genes in bacterial strains that are excellent rhizosphere colonizers. Pseudomonas fluorescens F113 is a biocontrol strain that was shown to be an excellent colonizer of numerous plant rhizospheres, including alfalfa. Although a derivative of F113 expressing polychlorinated biphenyl (PCB) biodegradation genes (F113pcb) has been reported previously, this strain shows a low level of bph gene expression, limiting its rhizoremediation potential. Here, a high-level expression system was designed from rhizobial nod gene regulatory relays. Nod promoters were tested in strain F113 by using β-galactosidase transcriptional fusions. This analysis showed that nodbox 4 from Sinorhizobium meliloti has a high level of expression in F113 that is dependent on an intact nodD1 gene. A transcriptional fusion of a nodbox cassette containing the nodD1 gene and nodbox 4 fused to a gfp gene was expressed in the alfalfa rhizosphere. ...

Peptidoglycan is a macromolecule made of long aminosugar strands cross-linked by short peptides. It forms the cell wall in bacteria surrounding the cytoplasmic membrane. The glycan strands are typically comprised of repeating N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) disaccharides. Each MurNAc is linked to a peptide of three to five amino acid residues. Disaccharide subunits are first assembled on the cytoplasmic side of the bacterial membrane on a polyisoprenoid anchor (lipid I and II). Polymerization of disaccharide subunits by transglycosylases and cross-linking of glycan strands by transpeptidases occur on the other side of the membrane. Bacterial cell wall biosynthesis inhibitors form a major class of antibiotics ...

Biosurfactants are amphiphilic compounds produced by microorganisms as secondary metabolite. Biosurfactants are microbially produced surface active agents and occur in nature as chemical entities such as glycolipids, phospholipids and lipopeptides. These molecules have attracted considerable scientific attention due to lower toxicity, higher biodegradability. The present study deals with the production and partial purification and characterization of a biosurfactant by Pseudomonas fluorescens. The properties of biosurfactant that was separated by acetone precipitation. The identification of the ability of pseudomonas fluorescens to produce biosurfactants and evaluation their antimicrobial potential are the aim of this work.. ...

Sequence analysis of domains 3 and 4 of 23S rRNA from Pseudomonas fluorescens Ag1 was carried out to allow the design of a strain-specific rRNA oligonucleotide probe targeting this strain. The specificity of the probe, Ps-Ag1, was assessed by dot blot analysis and whole-cell hybridization, and it was found to be specific for P. fluorescens Ag1. The correlation between the ribosomal content of P. fluorescens Ag1 and growth rate was determined during balanced growth conditions with generation times ranging from 1.2 to 31.8 h. Hybridization of the rRNA-targeting probes combined with charged coupled device-enhanced microscopy was used to determine the rRNA content. The total RNA content per cell was determined by staining with acridine orange and charged coupled device-enhanced microscopy. After 2 h under carbon starvation conditions, the rRNA content per cell decreased to 45% of the content of an exponentially growing cell. After 1 day of carbon starvation, the rRNA content had decreased to 20%. ...
Plants of which the roots are colonized by selected strains of non-pathogenic, fluorescent Pseudomonas spp. develop an enhanced defensive capacity against a broad spectrum of foliar pathogens. In Arabidopsis thaliana, this rhizobacteria-induced systemic resistance (ISR) functions independently of salicylic acid but requires responsiveness to jasmonic acid and ethylene. In contrast ... read more to pathogen-induced systemic acquired resistance (SAR), ISR is not associated with systemic changes in the expression of genes encoding pathogenesis-related (PR) proteins. To identify genes that are specifically expressed in response to colonization of the roots by ISR-inducing Pseudomonas fluorescens WCS417r bacteria, we screened a collection of Arabidopsis enhancer trap and gene trap lines containing a transposable element of the Ac/Ds system and the GUS reporter gene. We identified an enhancer trap line (WET121) that specifically showed GUS activity in the root vascular bundle upon colonization of the ...

We have found that the recognition event appears to require transfer of the Avr protein into the plant cell. Elicitation of a genotype-specific HR was observed with avrB+ P. fluorescens in soybean and ...

Abstract: The inoculation of forest seedlings with mycorrhizal fungi and rhizobacteria can improve the morphology and physiology of the seedlings and benefit the reforestation of Mediterranean areas and the reintroduction of mycorrhizal fungal inocula into these areas. Pinus nigra subsp. salzmannii,a forest component of the Mediterranean natural ecosystems, is currently used in the reforestation of Mediterranean regions. Its roots are able to form an ectomycorrhizal symbiosis with the Ascomycetes fungus Tuber melanosporum Vitt., the black truffle. The ecological, economic and social values of this ectomycorrhizal fungus is well known. Previously, we demonstrated that the inoculation of Pinus halepensis seedlings with Pseudomonas fluorescens CECT 844 rhizobacteria and the black truffle T. melanosporum improved the plant growth and N absorption of the seedlings. Furthermore, the addition of P. fluorescens CECT 844 doubled the rate of mycorrhization of T. melanosporum. In the present work, P. nigra

We investigated the phylogeny of 93 sequenced strains within the Pseudomonas fluorescens complex using state-of-the-art whole-genome sequence-based methods such as the Genome Blast Distance Phylogeny approach. As a result we divided the P. fluorescens complex into eight phylogenomic groups that agree with previous works based on type strains. Digital DDH (dDDH; http://ggdc.dsmz.de) identified 69 species and 75 subspecies among the 93 strains. The eight groups corresponded to clustering with a threshold of 31.8% dDDH. The article was published in PLoS ONE.. ...
The pattern (space versus time) and scale (relative to the lifetime of individuals) of environmental variation is thought to play a central role in governing the evolution of the ecological niche and the maintenance of genetic variance in fitness. To evaluate this idea, we serially propagated an initially genetically uniform population of the bacterium Pseudomonas fluorescens for a few hundred generations in environments that differed in both the pattern and scale at which two highly contrasted carbon substrates were experienced. We found that, contrary to expectations, populations often evolved into a single niche specialist adapted to the less-productive substrate in variable environments and that the genetic variance in fitness across different components of the environment was not generally higher in variable environments when compared with constant environments. We provide evidence to suggest that our results reflect a novel constraint on niche evolution imposed by the supply of beneficial ...
A central process in evolution is the recruitment of genes to regulatory networks. We engineered immotile strains of the bacterium Pseudomonas fluorescens that lack flagella due to deletion of the regulatory gene fleQ. Under strong selection for motility, these bacteria consistently regained flagella within 96 hours via a two-step evolutionary pathway. Step 1 mutations increase intracellular levels of phosphorylated NtrC, a distant homolog of FleQ, which begins to commandeer control of the fleQ regulon at the cost of disrupting nitrogen uptake and assimilation. Step 2 is a switch-of-function mutation that redirects NtrC away from nitrogen uptake and toward its novel function as a flagellar regulator. Our results demonstrate that natural selection can rapidly rewire regulatory networks in very few, repeatable mutational steps.. ...
Guangdong Province Material Testing Center, Guangzhou, China. We present evidence of selenium bioaccumulation at lower levels of the aquatic food chain and its antagonistic effect against mercury and methyl mercury assimilation in the aquatic food web. Most of our studies were carried out in freshwater lakes of the mining region of Sudbury, Ontario, Canada where the presence of metal smelters has introduced elevated levels of selenium in the surrounding terrestrial and aquatic ecosystems. The studies with different types of aquatic organisms demonstrate a consistent inverse relationship between concentrations of mercury/methyl mercury and selenium in whole bodies (zooplankton, benthic invertebrates, mayflies and amphipods, beetle larvae and newly hatched perch) or in muscle, liver and brain (perch and walleye). This antagonistic effect was also observed in laboratory controlled experiments with the incubated soil and surface water bacterium Pseudomonas fluorescens. We also present some ...
Yondelis (trabectedin, ecteinascidin-743, ET-743) is an anticancer natural product isolated from a marine organism, the tunicate Ecteinascidia turbinata. The compound was initially extracted from the naturally growing and farmed tunicate, but now its manufactured by semi-synthesis from a structurally-related metabolite produced by the bacterium Pseudomonas fluorescens. It is likely that the actual producer of Yondelis is not the tunicate itself but some unknown, symbiotic bacteria living in close relationship to the tunicate. The drug is being developed by PharmaMar, a Spanish biopharmaceutical company subsidiary of the Zeltia Group. For several years, Yondelis has being studied in clinical trials for treatment of several cancer types ...
Recently it was shown that Pi concentration regulates biofilm formation by Pseudomonas fluorescens Pf0-1 through a cyclic di-GMP (c-di-GMP) signaling pathway. Study of this response has produced one of the more complete pictures of how c-di-GMP signaling can link an environmental signal to a complex biological output. This research supports the idea that c-di-GMP is a conserved modality in biofilm regulation, with distinct outputs in different organisms, and provides a paradigm for conditional, transcriptional control of c-di-GMP signaling pathways. The cellular c-di-GMP levels in wild-type (WT) and the rapA mutant were compared under Pi starvation conditions. While LapA was secreted by lapD mutants, it was not retained in the cell-associated protein fraction and was lost to the culture supernatant. This phenomenon is notably similar to what happens to LapA in these fractions when the WT is grown in low Pi, prompting investigation of LapDs role in Pho regulon control of LapA localization, discussed.
Pseudofactin II is a recently identified biosurfactant secreted by Pseudomonas fluorescens BD5, the strain obtained from freshwater from the Arctic Archipelago of Svalbard. Pseudofactin II is a novel compound identified as cyclic lipopeptide with a palmitic acid connected to the terminal amino group of eighth amino acid in peptide moiety. The C-terminal carboxylic group of the last amino acid forms a lactone with the hydroxyl of Thr3. Adhesion is the first stage of biofilm formation and the best moment for the action of antiadhesive and anti-biofilm compounds. Adsorption of biosurfactants to a surface e.g. glass, polystyrene, silicone modifies its hydrophobicity, interfering with the microbial adhesion and desorption processes. In this study the role and applications of pseudofactin II as a antiadhesive compound has been investigated from medicinal and therapeutic perspectives. Pseudofactin II lowered the adhesion to three types of surfaces (glass, polystyrene and silicone) of bacterial strains of five
A genomic library of Pseudomonas fluorescens subsp. cellulosa DNA constructed in pUC18 and expressed in Escherichia coli was screened for recombinants expressing 4-methylumbelliferyl beta-D-glucoside hydrolysing activity (MUGase). A single MUGase-positive clone was isolated. The MUGase hydrolysed cellobiose, cellotriose, cellotetraose, cellopentaose and cellohexaose to glucose, by sequentially cleaving glucose residues from the non-reducing end of the cello-oligosaccharides. The Km values for cellobiose and cellohexaose hydrolysis were 1.2 mM and 28 microM respectively. The enzyme exhibited no activity against soluble or insoluble cellulose, xylan and xylobiose. Thus the MUGase is classified as a 1,4-beta-D-glucan glucohydrolase (EC and is designated 1,4-beta-D-glucan glucohydrolase D (CELD). When expressed by E. coli, CELD was located in the cell-envelope fraction; a significant proportion of the native enzyme was also associated with the cell envelope when synthesized by its ...

Abiotic and biotic environmental stressors play a key role in the ecophysiology of most organisms. As the presence and activity of stress-inducing agents vary along the day, organisms that are able to predict these periodic changes are better fit to survive. Caenorhabditis elegans, a soil-dwelling nematode, is subjected to daily changes in its natural environment, and its tolerance to osmotic and oxidative stress varies along the day. Pseudomonas fluorescens strain CHA0 is a soil bacterium that produces a set of secondary metabolites that antagonize phytopathogenic fungi and therefore promote healthy growth of several plant species. Here we show that strain CHA0 is able to affect C. elegans either under growth limiting conditions (i.e., slow-killing) or by rapid paralysis in nutrient replete conditions (fast-killing). Both types of toxicity require the post-transcriptional Gac/Rsm regulatory cascade, and the fast paralytic killing depends strongly on hydrogen cyanide production. The response ...
Selenium and silver have unique properties and great potential in the field of physics, chemistry and biology. The bacterial strain Pseudomonas fluorescens was isolated by using KingsB media and Cladosporium sp. was isolated by using potato dextrose agar for soil sample collected from Andhra Pradesh coal field of Singareni. Rapid formation of stable silver and selenium nanoparticles (AgNPs; SeNPs) were observed on exposure of the microbial culture with solution of silver nitrate and sodium selenite. The nanoparticles were characterized by UV-visible spectroscopy, X-ray diffraction (XRD) and atomic force microscopy (AFM). Further, the biologically synthesized nanoparticles were found to have efficient antimicrobial activity against pathogenic bacteria, thus implying significance of the present study in production of biomedical products. AgNPs synthesized by P. fluorescens showed more antimicrobial activity than Cladosporium sp. As the AgNPs are much smaller in size, they showed effective ...
After isolating and identifying the fluorescent pseudomonads, selecting an effective isolate is the first and foremost important step in biological control. P. fluorescens isolate AUPF6 showed the maximum inhibitory effect on mycelial growth. Fluorescent pseudomonads having antagonistic activity and increasing the plant growth would certainly be promising in evaluating suitable isolates in biological control. In addition to direct antagonism, P. fluorescens AUPF6 increased the activities of various defense-related enzymes and chemicals in response to infection by the pathogen. It is well known that all plants are endowed with defense genes which are quiescent in nature and appropriate stimuli or signals are needed to activate them. It has been reported that application of P. fluorescens triggers/activates plants latent defense mechanisms in response to infection by pathogen. Inducing a plants own defense mechanism by prior application of a biological agent is a novel strategy in plant disease ...
Pseudomonas fluorescens EPS62e was selected during a screening procedure for its high efficacy in controlling infections by Erwinia amylovora, the causal agent of fire blight disease, on different plant materials. In field trials carried out in pear trees during bloom, EPS62e colonized flowers until the carrying capacity, providing a moderate efficacy of fire-blight control. The putative mechanisms of EPS62e antagonism against E. amylovora were studied. EPS62e did not produce antimicrobial compounds described in P. fluorescens species and only developed antagonism in Kings B medium, where it produced siderophores. Interaction experiments in culture plate wells including a membrane filter, which physically separated the cultures, confirmed that inhibition of E. amylovora requires cell-to-cell contact. The spectrum of nutrient assimilation indicated that EPS62e used significantly more or different carbon sources than the pathogen. The maximum growth rate and affinity for nutrients in immature ...
A pot experiment was performed to see the interactive potential of Glomus mosseae and Acaulospora laevis alone or in combination with Pseudomonas fluorescens on Ocimum basilicum L. under glass house conditions. Various morphological and physiological parameters were measured after 120 days. Although, all co-inoculation treatments showed beneficial effects but G. mosseae is found to be the most compatible strain found in the rhizosphere of basil plant. G. mosseae alone or in combination with other bioinoculants showed maximum increase in all the different parameters studied (plant height, fresh weight, dry weight, leaf number, inflorescence height, root and shoot phosphorus, acidic and alkaline phosphatase and oil content). The overall results demonstrate that the co-inoculation of P. fluorescens with AM fungi promotes higher mycorrhizal colonization enhancing nutrient acquisition especially phosphorus (P), producing plant growth hormones resulting in improvement of rhizospheric condition of ...
1. GAF inhibits the growth of the bacterium that causes fire blight. Biological properties and the genetic basis for biosynthesis of the Germination Arrest Factor (GAF) produced by the soil bacterium Pseudomonas fluorescens are only partially understood. ARS scientists at Corvallis, Oregon, worked with Oregon State University collaborators and demonstrated that GAF also exhibits a rather specific antimicrobial activity against Erwinia amylovora, the pathogen that causes fire blight in apples and pears. This group also demonstrated that certain amino acids reverse GAF inhibition of bacterial growth, an observation which suggests that GAF affects the activity of aminotransferases, enzymes that are involved in plant nitrogen metabolism. This accomplishment may have commercial applications for GAF and structurally similar compounds because aminovinlyglycine, a compound similar to GAF also inhibited the growth of the fire blight pathogen. 2. Abiotic stress signaling. Forage and turf grasses are ...

Banana (Musa spp.) is one of the most valuable agricultural crops in the world particularly in the tropical and subtropical countries. Nearly three fourth of banana plantation in Thailand grow a banana variety called Kluai Numwa which is highly susceptible for Panama disease caused by Fusarium oxysporum f.sp. cubense (Foc). The use of antagonistic microorganisms offers a more effective and sustainable way of controlling Foc comparing to chemical fungicides. While a number of antagonic microorganisms against Foc have been explored worldwide, biocontrol of Foc in Thailand almost exclusively focuses on the use of Trichoderma spp. In this project, we propose the development of alternative Foc biocontrol agents from rhizobacteria Pseudomonas fluorescens. Here, we plan to isolate, select, modify and prototype Foc biocontrol products from P. fluorescens in Thailand. Expected outcomes of this project includes a) discovery and characterisation of new P. fluorescens strains capable of suppressing Foc, ...
A second, more general mechanism by which Ap4A metabolism affects biofilm formation was also observed. In Pi-replete conditions, when Pho regulon expression was repressed, we observed that the apaH mutant produced approximately 2-fold more biofilm than the wild type produced. The increased propensity for surface attachment is explained by substantial increases in the amount of LapA attached to the outer membrane and the concurrent increases in the level of intracellular c-di-GMP.. In both cases, Ap4A modulates biofilm formation by altering the concentration of c-di-GMP. In low-Pi conditions this connection is mediated through the Pho regulon and RapA; however, mechanisms connecting increases in the Ap4A level with Pho-independent increases in the c-di-GMP level are less obvious. One possibility that we have begun to explore is that imbalances in general nucleotide pools due to a block in Ap4A turnover result in changes in c-di-GMP pools in the cell. Whole-cell nucleotide analysis indicated that, ...

The Pseudomonas genus is a big problem mainly for the poultry food industry. The shelf life of chicken carcasses stored under refrigeration is limited by the appearance of undesirable odors and sliminess surface generated primarily by Gram negative bacteria. Due to the subsequent emergence of resistant bacteria, is necessary proving new alternatives as guaranty the microbiological quality of foods and human health. Bacteriophages or phages are viruses of bacteria that use resources of bacteria for their replication and killing bacteria naturally, showing them as a potential tool for bacteria biocontrol in food industry. In this study, 11 bacteriophages were isolated from the exudate product of defrost of chicken carcasses using as host strains Pseudomonas aeruginosa (ATCC 25619) and Pseudomonas fluorescens (ATCC 13525). This study also aimed at the purification, quantification and morphological and molecular characterization of phages (RFLP). Bacteriophage can be found in all types of ...

Lipase produced by a psychrotroph, Pseudomonas fluorescens P38, was found to catalyse the synthesis of butyl caprylate in n-heptane at low temperatures. The optimum yield of ester synthesis was 75% at 20 °C with an organic phase water concentration of 0.25% (v/v). The results are discussed in terms of the structural flexibility of psychrotroph-derived lipase and the activity of this enzyme within a nearly anhydrous organic solvent phase. ...
Nivatha Balendra, an 18-year-old student at Montreals Marianopolis College, may have found the answer to cleaning up oil spills in bodies of water right in her own backyard.. The young scientist found a particular strain of Pseudomonas fluorescens bacteria while rooting around in her backyard and along the St. Lawrence river. The bacteria is used in biocontrol methods - that is, organic solutions to controlling oil spills..

Results : About 50% of the mRNA-sequencing reads in BME were non-bovine; after contig assembly, up to two thirds of the non-bovine reads mapped to microbial mRNAs (Fig. 1B). IRDye-capB mRNA accumulated in murine intestinal mucosa and liver (and perhaps brain) 6 h and 24 h, respectively, after oral gavage (Fig. 2). Microbial mRNAs, including 55 and 36 mRNAs from P. fluorescens and E. coli were detected in human plasma after but not before a milk meal (Tables 1, 2). capB mRNA-loaded liposomes activated NF-kB and IFN signaling in reporter macrophages (Fig. 3A). C57BL/6 mice fed a BME-depleted diet died within 11 days of influenza A challenge whereas controls fed a BME-sufficient diet survived (Fig. 3B).. ...
