High intracellular c-di-GMP levels antagonize quorum sensing and virulence gene expression in Burkholderia cenocepacia H111
Ontology highlight
ABSTRACT: In this study, we have analysed the transcriptional profile of B. cenocepacia H111 upon artificially altering the global cellular c-di-GMP levels. A total of 111 genes was found to be differentially expressed, of which 96 genes were down-regulated when c-di-GMP concentrations were increased. The BDSF, AHL and c-di-GMP regulons overlap for the regulation of 24 genes. Intriguingly, at a high intracellular c-di-GMP level expression of the AHL synthase cepI was found to be more than 10-fold down-regulated. Among the exclusively c-di-GMP regulated genes were genes of the phenylacetate catabolic pathway and of the type III secretion system.
