Genes whose expression is significantly modulated by σ^E.

aGenes are grouped by putative or known operons (ordered in the direction of transcription). Genes whose expression was found to be significantly modulated are in bold (see Materials and Methods). Genes whose expression was determined by Q-PCR are underlined, and the fold change thus determined is indicated in parentheses after the microarrays value. Genes previously reported to be σE-regulated are indicated by uppercase letters that refer to the concerned study with the following codification: D, reported in [99]; K, reported in [37]; Re, reported in [100]; Rh, reported in [57]; and J, reported in [64]. bb numbers correspond to genes of the first column. cThe fold changes indicate the ratios of gene signal intensities of strains containing pZE21-rpoE to the reference signals (see Materials and Methods). Values correspond and follow the order of genes from the first column. The ratio value of genes not significantly modulated is indicated as “-”. Numbers in italics indicate a p-value>0.01 in case of microarrays or >0.05 in case of qRT-PCR. dMicroarray and qRT-PCR data concerning yaiY were divergent. We consider that yaiY results issued from microarray experiments are likely to be artifacts, possibly due to spotting of a non-yaiY–specific PCR product.
