Pseudomonas fluorescens ET76 was isolated from rice rhizosphere in northwestern Morocco. Its draft genome was estimated to be 6,681,652 bp with 5,789 coding sequences (CDSs). Genes encoding for type I to VI secretion systems, PvdQ, proteases, siderophores, hydrogen cyanide synthase, ACC-deaminase, among others, highlight its potential use in biological control of plant pathogens.

Twenty Pseudomonas fluorescens strains were isolated from rice growing soil samples and characterized. One of the P.fluorescens isolated and identified from the dual culture test. It was fermented for secondary metabolite in a small scale and extracted with ethyl acetate. The isolated metabolite tested against rice fungal pathogens. The structure of the compound was elucidated by high-resolutio...

Herein, we report the draft genome sequence of Pseudomonas fluorescens strain CREA-C16, a plant growth-promoting rhizobacterium that was isolated from the rhizosphere of Pisum sativum L. plants. The genome sequence is ~6 Mb in size, with a G+C content of 60.1%, and includes 4,457 candidate protein-encoding genes.

INTRODUCTION Antibiotic sensitivity and the effect of temperature on microbial growth are two standard laboratory activities found in most microbial laboratory manuals. We have found a novel way to combine the two activities to demonstrate how temperature can influence antibiotic sensitivity using a standard incubator in instructional laboratory settings. This activity reinforces the important ...

Pseudomonas fluorescens Pf0-1 exhibited chemotactic responses to l-malate, succinate, and fumarate. We constructed a plasmid library of 37 methyl-accepting chemotaxis protein (MCP) genes of P. fluorescens Pf0-1. To identify a MCP for l-malate, the plasmid library was screened using the PA2652 mutant of Pseudomonas aeruginosa PAO1, a mutant defective in chemotaxis to l-malate. The introduction o...

Type VI secretion systems (T6SSs) are widespread in Gram-negative bacteria, including Pseudomonas. These macromolecular machineries inject toxins directly into prokaryotic or eukaryotic prey cells. Hcp proteins are structural components of the extracellular part of this machinery. We recently reported that MFE01, an avirulent strain of Pseudomonas fluorescens, possesses at least two hcp genes, ...

Two bacterial species; Pseudomonas fluorescens and Pseudomonas putida and three different chemical compounds; copper sulphate (CuSO4), Indole butyric acid (IBA) and potassium chloride (KCl) were tested for their ability to induce resistance in lupine plants against wilt disease caused by Fusarium oxysporum f. sp. lupini. Treatment of seeds with the selected bacterial species and chemical compou...

Protozoan predation of bacteria can significantly affect soil microbial community composition and ecosystem functioning. Bacteria possess diverse defense strategies to resist or evade protozoan predation. For soil-dwelling Pseudomonas species, several secondary metabolites were proposed to provide protection against different protozoan genera. By combining whole-genome transcriptome analyses wi...

Phosphorus deficiency is a major constraint to crop production due to rapid binding of the applied phosphorus into fixed forms not available to the plants. This work was carried out to explain the release of soluble phosphates and its effect on plant growth as a function of phosphate solubilization by fluorescent Pseudomonas. In the current study, Pseudomonas fluorescens K 34 solubilized trical...

In this study we observed the proliferation of Pseudomonas fluorescens (P. fluorescens) in mouse organ homogenates at 4 degrees C. P. fluorescens secreted a protease possessing properties different from those of the mammalian tissue proteases. The specificity of this protease required a basic amino acid residue at the P1 position at a pH optimum of 6.0. The specificity of the protease was simil...
