Work conducted at our laboratoryillustrates a mechanism of adaptation of bacteria to different environments. After acquisition of new genes, the evolutionary pressure would focus on their regulatory sequences with the consequence of forcing the selection of specific regulatory binding sites and thus adapted expression through pre-existing signalling pathways.
