All genes that showed evidence for lower transcript levels in the ΔhrcA strain in the microarray comparison are listed (adjusted P value of <0.05; n-fold change of ≥1.5); as HrcA is a negative regulator, genes downregulated in the ΔhrcA strain are most likely indirectly affected by HrcA.
Putative operons are in bold font; gene names correspond to the gene designations for L. monocytogenes strain EGD-e (as listed on the ListiList server http://genolist.pasteur.fr/ListiList/).
Positive changes indicate genes that have higher transcript levels in the L. monocytogenes parent strain.
