Gene expression by cells exposed to 0 (control) or 1 mM H₂O₂ measured by qPCR as mRNA normalized to the DNA copy number of the corresponding gene. a Expression of tfdA involved in the first step of MCPA degradation. b Expression of the ohr/osmC-like gene putatively involved in a response to oxidative stress in C. pinatubonensis AEO106. Data are mean values from triplicate cultures from one representative experiment (the experiment was repeated twice). Error bars represent standard errors of means
