We provide here a comparative genome analysis of ten strains within the Pseudomonas fluorescens group including seven new genomic sequences. These strains exhibit a diverse spectrum of traits involved in biological control and other multitrophic interactions with plants, microbes, and insects. Multilocus sequence analysis placed the strains in three sub-clades, which was reinforced by high leve...
nas incognita have been previously described as being able to utilize citronellol, geraniol, and linalool (3, 6). Recently, a 50-megadalton (MDa) plasmid has been associated with the degradation of geraniol (9). In this report we describe the isolation of a Pseudomonas fluorescens s train capable of utilizing linalool as a sole carbon and energy source and demonstrate the presence of a transmis...
Pseudomonas fluorescens Q8r1-96 represents a group of rhizosphere strains responsible for the suppressiveness of agricultural soils to take-all disease of wheat. It produces the antibiotic 2,4-diacetylphloroglucinol and aggressively colonizes the roots of cereal crops. In this study, we analyzed the genome of Q8r1-96 and identified a type III protein secretion system (T3SS) gene cluster that ha...
Four gram-negative bacterial species, including Escherichia coli strain B, Serratia marcescens, Pseudomonas fluorescens, and Vibrio cholerae (comma) strain NIH 41, were investigated for fatty acid content by gas-liquid chromatography involving a preparatory technique which facilitated detection of cyclopropane fatty acids. Methyl esters of fatty acids were subjected to mild catalytic hydrogenat...
In the terrestrial ecosystem, plant-microbe symbiotic associations are ecologically and economically important processes. To better understand these associations at structural and functional levels, different molecular and biochemical tools are applied. In this study, we have constructed a suite of vectors that incorporates several new elements into the rhizosphere stable, broad-host vector pME...
Attachment of certain bacteria to living arbuscular mycorrhizal fungal extraradical hyphae may be an important prerequisite for interactions between these microorganisms, with implications for nutrient supply and plant health. The attachment of five different strains of gfp-tagged soil bacteria (Paenibacillus brasilensis PB177 (pnf8), Bacillus cereus VA1 (pnf8), Pseudomonas fluorescens SBW25<gf...
Fungal pathogens pose a major problem in causing reduction in yield of vanilla crop to considerable level. Fusarium oxysporum, was isolated from naturally infected vanilla plants and an attempt was made to minimize the damage caused by the pathogen using biocontrol agents Trichoderma harzianum, and Pseudomonas fluorescens isolated from soil. The combined inoculation of Trichoderma harzianum wit...
هدف از این تحقیق ارزیابی باکتری pseudomonas fluorescens و قارچ metarhizium anisopliae به طور جداگانه و تلفیقی جهت کنترل بیولوژیک نماتد مولد غده گوجه فرنگی در شرایط آزمایشگاهی و گلخانه ای بود. جدایه های مختلف باکتری p. fluorescens از خاک منطقه بویراحمد جداسازی و شناسایی گردید و اثر بیوکنترلی آن ها بر نماتد مولد غده در آزمایشگاه و گلخانه مورد بررسی قرار گرفت. همه ی جدایه های مورد بررسی در آزمایش...
