  1. Gene expression values (log2 ratio of median) for all genes/operons alluded in the revised model of sulfur oxidation in A. ferrooxidans ATCC 23270. Genes with a log2 ratio of median larger than |1.5| (corresponding to genes induced more than 2.8 fold) are considered differentially expressed (indicated with *) and genes p-value <0,005 are considered significant. Gene ID is that of Genbank genome annotation NC 011761. The reference and the strain in which the level of the gene product has been shown to be higher in S0 than in Fe(II) conditions are indicated in the last column.
