Cell cycle regulation in bacteria.

Significant progress has been made in the study of ftsZ expression and the topology of FtsZ protein localization in Escherichia coli cells. Exciting results on the identification of new genes required for chromosome resolution and partitioning after the completion of DNA synthesis have also been reported. A recent area of study is asymmetric cell division and its role in differentiation in Bacillus subtilis and Caulobacter crescentus. Biochemical activities of bacterial cell division gene products are also beginning to be addressed.
