A Burkholderia cenocepacia orphan LuxR homolog is involved in quorum-sensing regulation.

Malott Rebecca J RJ O'Grady Eoin P EP Toller Jessica J Inhülsen Silja S Eberl Leo L Sokol Pamela A PA

Journal of bacteriology 20090206 8

Burkholderia cenocepacia utilizes quorum sensing to control gene expression, including the expression of genes involved in virulence. In addition to CepR and CciR, a third LuxR homolog, CepR2, was found to regulate gene expression and virulence factor production. All B. cenocepacia strains examined contained this orphan LuxR homolog, which was not associated with an adjacent N-acyl-homoserine lactone synthase gene. Expression of cepR2 was negatively autoregulated and was negatively regulated by ...[more]

Transcription profiling by array of Burkholderia cenocepacia J2315 grown under low or atmospheric oxygen concentration conditions

Project description:B. cenocepacia J2315 was grown on LB medium to mid-stationary phase at OD 0.3 under full aeration and then transferred into a 50 ml centrifuge tube and placed upright into a CampyGen Compact (Oxoid, Basingstoke, UK) plastic pouch containing the gas generating paper sachet. The pouch was sealed immediately and then the cap of the centrifuge tube loosened to allow exchange of atmosphere between centrifuge tube and pouch. The culture was further incubated at 37 degrees centigrade and 150 rpm for 2-3 hours until it reached OD 0.5. The centrifuge tube was sealed before opening the pouch and then snap-cooled before harvest to minimise exposure to atmospheric oxygen and to ensure expression profiles reflect the lower oxygen concentration. The expression profile was compared to cells grown to OD 0.5 at atmospheric oxygen concentrations.
