Genome-wide investigations of gene expression at the transcriptional level in cyanobacteria, using DNA microarrays, have allowed identification of genes whose expression is induced or repressed by various types of environmental stress and also of previously uncharacterized genes that appear to be involved in stress responses. Acclimation to stress begins with perception of stress and transduction of the stress signal. A combination of the systematic mutation of potential sensors and transducers and DNA microarray analysis has led to significant progress in understanding the mechanisms of perception of and reaction to environmental stress in cyanobacteria. In this chapter, we summarize recent progress in the identification of stress-inducible genes and of systems that regulate responses to stress that has been made using DNA microarrays in cyanobacteria and, in particular, in Synechocystis sp.
