  • a Numbers and percentages indicate the overlap in the results of the studies on diamide stress (38), oxidative stress (ROS) (46), and Spx overproduction (50) and this study.

  • b Down, lowered expression; up, elevated expression in response to the specific stresses (38, 46, 50).

  • c The values 25 and 100 μM correspond to the concentration of IPTG in the medium. Down and up indicate the directionality of the response in the ItrxA array experiments.
