Regulation of late flagellar gene transcription and cell division by flagellum assembly in Caulobacter crescentus.
Biogenesis of the single polar flagellum of Caulobacter crescentus is regulated by a complex interplay of cell cycle events and the progression of flagellum assembly. The expression of class III/IV flagellar genes requires the assembly of an early flagellar basal body structure, encoded by class II genes, and is activated by the transcription factor FlbD. Previous experiments indicated that the...
متن کاملCell cycle regulation and cell type-specific localization of the FtsZ division initiation protein in Caulobacter.
Many genes involved in cell division and DNA replication and their protein products have been identified in bacteria; however, little is known about the cell cycle regulation of the intracellular concentration of these proteins. It has been shown that the level of the tubulin-like GTPase FtsZ is critical for the initiation of cell division in bacteria. We show that the concentration of FtsZ var...

متن کاملDependence of cell division on the completion of chromosome replication in Caulobacter.
The relationship between chromosome replication and cell division in the stalked bacterium Caulobacter crescentus has been investigated. Two compounds, hydroxyurea and mitomycin C, were found to inhibit completely deoxyribonucleic acid (DNA) synthesis while allowing continued cell growth and elongation. When these inhibitors were added to exponentially growing cultures, cell division stopped af...
متن کاملFtsEX-mediated regulation of the final stages of cell division reveals morphogenetic plasticity in Caulobacter crescentus
During its life cycle, Caulobacter crescentus undergoes a series of coordinated shape changes, including generation of a polar stalk and reshaping of the cell envelope to produce new daughter cells through the process of cytokinesis. The mechanisms by which these morphogenetic processes are coordinated in time and space remain largely unknown. Here we demonstrate that the conserved division com...
