A Rhodococcus qsdA-Encoded Enzyme Defines a Novel Class of Large-Spectrum Quorum-Quenching Lactonases
TLDR
Bacteria harboring the qsdA gene interfere very efficiently with quorum-sensing-regulated functions, demonstrating that qSDA is a valuable tool for developing quorum -quorum-quenching procedures. Expand
Quorum Sensing and Quorum Quenching: The Yin and Yang of Bacterial Communication
TLDR
This work has shown that light emission by V. fischeri depends upon the bacterial cell density, and only occurs at high cell densities, which explains why V.fischeri only produces light in the fish organ where it lives at very high densities. Expand
Quorum-sensing system of Agrobacterium plasmids: analysis and utility.
TLDR
The physiological, genetic, biochemical, and structural studies of TraR and the target genes it regulates by quorum sensing have contributed to the understanding of the nature of these systems as well as the molecular mechanisms by which acylhomoserine lactone signals are translated to gene regulation through LuxR-like transcription factors. Expand
Novel bacteria degrading N-acylhomoserine lactones and their use as quenchers of quorum-sensing-regulated functions of plant-pathogenic bacteria.
TLDR
The diversity of the QS-interfering bacteria in the rhizosphere is revealed and the validity of targeting QS signal molecules to control pathogens with natural bacterial isolates is demonstrated. Expand
N-Acylhomoserine lactone quorum-sensing molecules are modified and degraded by Rhodococcus erythropolis W2 by both amidolytic and novel oxidoreductase activities.
TLDR
The Rhodococcus erythropolis strain W2 is shown to be capable of modifying and degrading AHL signal molecules through both oxidoreductase and amidolytic activities. Expand
Acyl-Homoserine Lactone Production Is More Common among Plant-Associated Pseudomonas spp. than among Soilborne Pseudomonas spp
TLDR
A total of 137 soilborne and plant-associated bacterial strains belonging to different Pseudomonas species were tested for their ability to synthesize N-acyl-homoserine lactones (NAHL), and sequence analysis revealed the existence of aluxI homologue that was sufficient to confer NAHL synthesis upon its bacterial host and has strong homology to psyI and ahlI, two genes involved in NAHL production in P. syringae pv. Expand
Genetically engineered plants producing opines alter their biological environment
TLDR
Using opine-producing GEP, it is shown that transgenic plants alter their biological environment, more precisely the root-associated bacterial populations, both transgene-specific and target population-specific. Expand
Agrobacterium is a definable genus of the family Rhizobiaceae.
TLDR
It is concluded that there is little scientific support for the proposal to group the agrobacteria into the genus Rhizobium and consequently recommend retention of the genus AGROBACTERIUM. Expand
Pyrococcus CH1, an obligate piezophilic hyperthermophile: extending the upper pressure-temperature limits for life
TLDR
Comparisons of growth yields obtained under high-temperature/high-pressure conditions for relative organisms isolated from various depths, showed clear relationships between depth at origin and responses to hydrostatic pressure. Expand
Adaptation of the membrane in Archaea.
TLDR
Evidence for homeoviscous adaptation in Archaea is reviewed, the limits of this strategy are discussed, and the knowledge in this very peculiar domain of life is discussed. Expand
