Reduction in the expression of exoenzyme genes in the corA ^‐ mutant.

Gene	Fold decrease*, †

^* Measured by reverse transcriptase‐quantitative polymerase chain reaction (RT‐qPCR).

^† Expressed as the ratio of gene expression in parent KD100 compared with that of the corA ^‐ mutant KD101 normalized to the level of expression of the recA gene using the method of Schmittgen and Livak (2008). Values are the mean ± standard deviation.
