Bacterial morphogenesis: learning how cells make cells.

abstract：:Much of what we know about cytokinesis in bacteria has come from studies with Escherichia coli, and efforts to comprehensively understand this fundamental process in this organism continue to intensify. Major recent advances include in vitro assembly of a membrane-tethered version of FtsZ into contractile rings in lip...
