We are studying the global organization of bacterial genomes and its dynamics during the cell cycle and evolution by horizontal gene transfer. Using Escherichia coli as a model organism and a multi-scale approach involving biochemistry, biophysics, molecular genetics and cell biology, we put emphasis on the last steps of chromosome segregation and their integration with the cell cycle and cell division. We also investigate how the molecular machines involved in late segregation are domesticated by mobile genetic elements for their integration as bona fide parts of their host genome.
