Pseudomonas aeruginosa causes severe and persistent infections in immune compromised
individuals and cystic fibrosis sufferers. The infection is hard to eradicate as P. aeruginosa …

The Pseudomonas quinolone signal (PQS) has been studied primarily in the context of its
role as a quorum-sensing signaling molecule. Recent data suggest, however, that this …

Quorum sensing is a process of cell-cell communication that bacteria use to regulate
collective behaviors. Quorum sensing depends on the production, detection, and group …

The rhizosphere encompasses the millimeters of soil surrounding a plant root where
complex biological and ecological processes occur. This review describes recent advances …

Pseudomonas aeruginosa is a Gram-negative γ-Proteobacterium which is known for its
capacity to colonize various niches, including some invertebrate and vertebrate hosts …

Bacteria were for a long time believed to exist as individual cells that sought primarily to find
nutrients and multiply. The discovery of intercellular communication among bacteria has led …

We show that a single clinical isolate of the human opportunistic pathogen Pseudomonas
aeruginosa (strain PA14), which previously was shown to be pathogenic in mice and plants …

Two seven-gene phenazine biosynthetic loci were cloned from Pseudomonas aeruginosa
PAO1. The operons, designated phzA1B1C1D1E1F1G1 and phzA2B2C2D2E2F2G2, are …

Bacteria communicate through the production of diffusible signal molecules termed
autoinducers. The molecules are produced at basal levels and accumulate during growth …

Random transposon insertion libraries have proven invaluable in studying bacterial
genomes. Libraries that approach saturation must be large, with multiple insertions per …
