^aShown are a subset of genes identified to be differentially expressed in the mutants and further analyzed in this work. Complete lists of genes that were differentially expressed in the mutants are shown in Tables S3 and S4 in the supplemental material.

^bExpression of genes was increased or decreased 2-fold in the C. jejuni ΔCjj1484 mutant.

^cExpression of genes was increased or decreased 2-fold in the C. jejuni ΔCjj1483 mutant.

^dGenes were divided into one of four classes, as described in the text, based on their expression in the C. jejuni ΔCjj1484 and ΔCjj1483 mutants.

^eExpression of these genes was not affected in the C. jejuni ΔCjj1484 strain, as determined by microarray analysis.

^fExpression of this gene was not affected in the C. jejuni ΔCjj1483 strain, as determined by microarray analysis.
