  1. Real time PCR gene expression values (log2 ratio of median) for relevant genes alluded in the revised iron or sulfur oxidation models for 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 *). 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 one of the conditions tested (Fe(II) or S0) are indicated in the last column.
