Genes involved in the oxidative stress response that are differentially expressed under Na+ depleted conditions.

aLoci numbers are those from the annotation of the genome of strain W83 and the microarrays.bFold expression.cP values were calculated using LIMMA.dThe microarray PCR amplicon for rprY is upstream from the erythromycin resistance cassette that was used to generate the rprY mutation, thus an expression signal was still detectable.
