  1. Fold-changes of selected differentially expressed genes of the strain MG1363 in O2 condition in comparison with N2 condition, from a whole-genome microarray analysis (n = 3). Genes were significantly (p-value < 0.5) differentially expressed with a FDR < 0.5 and a |fold-change| > 2. Top table is over-expressed genes; bottom table is under-expressed genes. Under-expressed genes; the ninth last genes are involved in the conjugation.
