Pseudomonas aeruginosa produces the toxic secondary metabolite hydrogen cyanide (HCN) at high cell population densities and low aeration. We have used Affimetrix microarrays to investigate the impact of HCN as a signal in cell-cell communication by comparing the transcriptome of the wild-type strain PAO1 to that of an HCN-negative mutant (PAO6344) under cyanogenic conditions. Total RNA was extracted from cultures of the wild-type strain PAO1 as well as from the isogenic HCN negative mutant (PAO6344), when HCN production was maximal (i.e. end of exponential growth phase). Each RNA pool derived from 3 technical replicates. 1 biological replicate per strain was performed on a different day.
