The literature demonstrating tight regulation of the Escherichia coli cell cycle is reviewed. Recent evidence is presented indicating that the normal rod cell shape can be abandoned, allowing growth as a coccus, either by increasing the amount of the division proteins FtsZ, FtsA and FtsQ, or by increasing the pool of the nucleotide ppGpp. It is argued that ppGpp may be a cell cycle signal in E. coli.
