| genotypic comparison of pantoea agglomerans plant and clinical strains. | pantoea agglomerans strains are among the most promising biocontrol agents for a variety of bacterial and fungal plant diseases, particularly fire blight of apple and pear. however, commercial registration of p. agglomerans biocontrol products is hampered because this species is currently listed as a biosafety level 2 (bl2) organism due to clinical reports as an opportunistic human pathogen. this study compares plant-origin and clinical strains in a search for discriminating genotypic/phenotypic ... | 2009 | 19772624 |
| characterization of a broad-host-range flagellum-dependent phage that mediates high-efficiency generalized transduction in, and between, serratia and pantoea. | a phage (phiot8) isolated on serratia sp. atcc 39006 was shown to be flagellum-dependent, and to mediate generalized transduction with high efficiency (up to 10(-4) transductants per p.f.u.). phiot8 was shown to have a broad host range because it also infected a strain of pantoea agglomerans isolated from the rhizosphere. transduction of plasmid-borne antibiotic resistance between the two bacterial genera was demonstrated, consistent with purported ecological roles of phages in dissemination of ... | 2010 | 19778959 |
| a single genetic locus in the phytopathogen pantoea stewartii enables gut colonization and pathogenicity in an insect host. | aphids are typically exposed to a variety of epiphytic and phytopathogenic bacteria, many of which have entomopathogenic potential. here we describe the interaction between pantoea stewartii ssp. stewartii dc283 (dc283), an enteric phytopathogen and causal agent of stewart's wilt, and the pea aphid, acyrthosiphon pisum. when ingested by aphids, dc283 establishes and aggregates in the crop and gut, preventing honeydew flow and excretion, resulting in aphid death in 72 h. a mutagenesis screen iden ... | 2010 | 19788413 |
| association and attraction of blueberry maggot fly curran (diptera: tephritidae) to pantoea (enterobacter) agglomerans. | the attraction of washed, medium-free cells of pantoea (enterobacter) agglomerans to wild, adult rhagoletis mendax curran, the blueberry maggot fly, was evaluated in managed blueberry fields in maine. attraction was evaluated using pherocon am and ladd traps, each tested with or without washed bacterial cells. field studies showed significant increases in fly captures on the pherocon am traps. apple volatiles odors on ladd traps seemed to cancel the effects of bacterial odors. aerobic heterotrop ... | 2009 | 19791604 |
| polyphasic study of plant- and clinic-associated pantoea agglomerans strains reveals indistinguishable virulence potential. | pantoea species are ubiquitous in nature and occasionally associated with infections caused by contaminated clinical material. hence, pantoea agglomerans is considered as an opportunistic pathogen of humans. since species of the genus pantoea and closely related species of other enterobacteriaceae genera are phenotypically very similar, many clinical isolates are misassigned into p. agglomerans based on the use of quick commercial-offered biochemical tests. our objective was to find markers enab ... | 2009 | 19800991 |
| the atp-dependent amide ligases ddag and ddaf assemble the fumaramoyl-dipeptide scaffold of the dapdiamide antibiotics. | the enzymes ddag and ddaf, encoded in the pantoea agglomerans dapdiamide antibiotic biosynthetic gene cluster, when expressed in escherichia coli, form the tandem amide bonds of the dapdiamide scaffold at the expense of atp cleavage. ddag uses fumarate, 2,3-diaminopropionate (dap), and atp to make fumaroyl-amp transiently on the way to the n(beta)-fumaroyl-dap regioisomer. then ddaf acts as a second atp-dependent amide ligase, but this enzyme cleaves atp to adp and p(i) during amide bond formati ... | 2009 | 19807062 |
| structure/function analysis of the pantoea stewartii quorum-sensing regulator esar as an activator of transcription. | in pantoea stewartii subsp. stewartii, two regulatory proteins are key to the process of cell-cell communication known as quorum sensing: the luxi and luxr homologues esai and esar. most luxr homologues function as activators of transcription in the presence of their cognate acylated homoserine lactone (ahl) signal. however, esar was initially found to function as a repressor in the absence of ahl. previous studies demonstrated that, in the absence of ahl, esar retains the ability to function as ... | 2009 | 19820098 |
| 2-amino-3-(oxirane-2,3-dicarboxamido)-propanoyl-valine, an effective peptide antibiotic from the epiphyte pantoea agglomerans 48b/90. | the epiphyte pantoea agglomerans 48b/90, which has been isolated from soybean leaves, belongs to the enterobacteriaceae, as does the plant pathogen erwinia amylovora, which causes fire blight on rosaceous plants such as apples and leads to severe economic losses. since p. agglomerans efficiently antagonizes phytopathogenic bacteria, the p. agglomerans strain c9-1 is used as a biocontrol agent (blightban c9-1). here we describe the bioassay-guided isolation of a peptide antibiotic that is highly ... | 2009 | 19820144 |
| microbial diversity changes in soybean sprouts treated with enterocin as-48. | seed sprouts may act as vehicles for foodborne pathogenic bacteria. in the present study, the effect of washing treatment with the enterococcal bacteriocin enterocin as-48 on the microbiota of two batches of soybean sprouts was studied by culture-dependent and independent methods throughout storage at 10 degrees c. viable cell counts of bacteriocin-treated samples revealed some modifications only for lactic acid bacteria and enterococci during storage. in the control samples from batch 1, the cu ... | 2009 | 19835782 |
