RESUMO

DNA microarrays were used to compare gene expression in dividing and nondividing (filamentous) cultures of Escherichia coli. Although cells from these cultures differed profoundly in morphology, their gene expression profiles were nearly identical. These results extend previous evidence that there is no division checkpoint in E. coli, and progression through the cell cycle is not regulated by the transcription of different genes during different parts of the cell cycle.
