  • a Average microarray mRNA ratios of hfq+ wild type (CAG50008) versus the hfq mutant (CAG50009). Averages and standard deviations were calculated from the log2-transformed data of eight independent microarrays (the average ±1 standard deviation is given in parentheses). The values are presented as ratios.

  • b Data for first gene of operon.
