^aThe functional categorization of M. tuberculosis genes was based on their known functions as assigned by the TubercuList database (http://genolist.pasteur.fr/TubercuList/). For each gene, the changes in wild-type M. tuberculosis relative to the levels for the Δ-σ^H mutant in the pre-diamide stress samples and the 0-min-PDS samples are shown, along with standard deviations. Statistical significance was assigned using the ANOVA function within the S⁺ ArrayAnalyzer script.
