ABSTRACT
Abstract Our goal in this chapter is to review recent and current themes in the area of redox-dependent gene regulation. Over the last few years there has been an explosion in research looking at mechanisms of oxygen and redox sensing, transmission of these signals to the genome and their consequences on metabolism. These cover Grampositives and -negatives, facultative anaerobes as well as obligate aerobes and phototrophs. We focus on recent aspects of redox sensing and gene regulation only and highlight new areas of research in the field. This research field is flourishing and revealing some very surprising and exciting new science.
