Expression of oxidative stress genes in P. xenovorans LB400 upon exposure to paraquat or H₂O₂. Expression levels of oxidative stress genes were measured by RT-qPCR after strain LB400 exposure to paraquat (PQ) or H₂O₂ (1 mM) for 1 h. The gyrB gene was used as the reference gene. Fold-change levels were calculated as the mean ± SD of three independent experiments. The dotted lines indicate the level of expression from which a significant increase (2) or decrease (-2) of expression is observed
