Mace C, Seyer D, Chemani C, et al., 2008, Identification of Biofilm-Associated Cluster (bac) in Pseudomonas aeruginosa involved in biofilm formation and virulence, PLoS ONE, Vol: 3, ISSN: 1932-6203
Biofilms are prevalent in diseases caused by Pseudomonas aeruginosa, an opportunistic and nosocomial pathogen. By a proteomic approach, we previously identified a hypothetical protein of P. aeruginosa (coded by the gene pA3731) that was accumulated by biofilm cells. We report here that a ΔpA3731 mutant is highly biofilm-defective as compared with the wild-type strain. Using a mouse model of lung infection, we show that the mutation also induces a defect in bacterial growth during the acute phase of infection and an attenuation of the virulence. The pA3731 gene is found to control positively the ability to swarm and to produce extracellular rhamnolipids, and belongs to a cluster of 4 genes (pA3729–pA3732) not previously described in P. aeruginosa. Though the protein PA3731 has a predicted secondary structure similar to that of the Phage Shock Protein, some obvious differences are observed compared to already described psp systems, e.g., this unknown cluster is monocistronic and no homology is found between the other proteins constituting this locus and psp proteins. As E. coli PspA, the amount of the protein PA3731 is enlarged by an osmotic shock, however, not affected by a heat shock. We consequently named this locus bac for biofilm-associated cluster.

Ventre I, Goodman AL, Filloux A, et al., 2007, Modulation of bacterial lifestyles via two-component regulatory networks, Pseudomonas, Pages: 311-340, ISBN: 9781402060960
The ability of bacteria to survive in specific habitats requires the coordination of the expression of thousands of environmentally regulated genes. The complexity of these regulatory networks increases with the breadth of environments a bacterial species occupies. Species that are able to survive in a broad range of environments generally possess a large coding capacity and devote a significant portion of their genome to signal transduction and gene regulation. Myxococcus xanthus, a free-living bacterium known for its complex multicellular development and differentiation, uses 8% of its genome for regulation. In contrast, the habitat-restricted human pathogen Helicobacter pylori dedicates less than 2% of its genome toward this aim.

This volume collects new information on the genomics of saprophytic soil Pseudomonas, as well as functions related to genomic islands. Pseudomonas are ubiquitous inhabitants and this volume explores life styles in different settings and sheds further insights on the wide metabolic potential of this microbe for the removal of pollutants and production of added-value products. This volume also explores how Pseudomonas responds and reacts to environmental signals, including detection of cell density. This fifth volume covers: genomics, physiology and metabolism, databases, gene regulation, pathogenesis, and catabolism and biotransformations. The first four volumes of the Pseudomonas series covered the biology of pseudomonads in a wide context, including the niches they inhabit, the taxonomic relations among members of this group, the molecular biology of gene expression in different niches and under different environmental conditions, the analysis of virulence traits in plants, animals and human pathogens as well as the determinants that make some strains useful for biotechnological applications and promotion of plant growth.

Ramos JL, Filloux A, 2006, Preface, ISBN: 9780387288345
The five previous volumes of Pseudomonas series covered the biology of pseudomonads in a wide context, including the niches they inhabit, the taxonomic relations among members of this group, the molecular biology of gene expression in different niches and under different environmental conditions, the analysis of virulence traits in plants, animals and human pathogens as well as the determinants that make some strains useful for biotechnological applications and promotion of plant growth. Pseudomonas volume 6 is intended to collect new information on molecular microbiology, infection and biodiversity. This sixth volume covers the following topics: transcription regulation, virulence control, physiology and metabolism, bacteriology, microbial genetics and genomics. Pseudomonas volume 6 will be of use to researchers working on these bacteria, particularly those studying genomics, physiology, quorum sensing, life styles, metabolism etc. Advanced students in biology, medicine and agronomy will also find this volume a valuable reference during their studies.
