Bacterial Cell Cycles

Science, 2000
The array of genes that are expressed during the life cycle of a cell can be pictured as a complex genetic circuit. Laub et al. provide a global survey of the part of that circuit expressed during the cell cycle of Caulobacter crescentus , a bacterium that differentiates during ...

Control of the bacterial cell cycle

Current Opinion in Cell Biology, 1991
New insights into the control of DNA replication through growth, hemimethylated DNA and DnaA protein have been described. Fundamental shifts in thinking have resulted in the identification of new cell cycle genes with potential roles in initiation of DNA replication, chromosomal segregation and division.

Cell Type-Specific Phosphorylation and Proteolysis of a Transcriptional Regulator Controls the G1-to-S Transition in a Bacterial Cell Cycle

Cell, 1997
The global transcriptional regulator CtrA controls multiple events in the Caulobacter cell cycle, including the initiation of DNA replication, DNA methylation, cell division, and flagellar biogenesis.

Step by Step, Cell by Cell: Quantification of the Bacterial Cell Cycle

Trends in Microbiology, 2017
The Escherichia coli cell cycle is a classic, but we are still missing some of its essential aspects. The reason is that our knowledge is mostly based on population data, and our grasp of the behavior of single cells is still very limited. Today, new dynamic single-cell data promise to overcome this barrier. Existing data from single cells have already

Spatial complexity of mechanisms controlling a bacterial cell cycle

Current Opinion in Microbiology, 2004
Cell cycle progression in Caulobacter is governed by a multilayered regulatory network linking chromosome replication with polar morphogenesis and cell division. Temporal and spatial regulation have emerged as the central themes, with the abundance, activity and subcellular location of key structural and regulatory proteins changing over the course of ...

Choreographing the Bacterial Cell Cycle

Science, 1996
In the careful dance of a bacterial cell's life, particular movements, such as cell division or the development of particular cell structures, occur only after previous steps are completed. But scientists haven't been able to find a master choreographer—until now.

Regulation of the bacterial cell cycle by an integrated genetic circuit

Nature, 2006
How bacteria regulate cell cycle progression at a molecular level is a fundamental but poorly understood problem. In Caulobacter crescentus, two-component signal transduction proteins are crucial for cell cycle regulation, but the connectivity of regulators involved has remained elusive and key factors are unidentified.

Control of the Bacterial Cell Cycle by Cytoplasmic Growth

Critical Reviews in Microbiology, 2002
For free-living single-celled organisms, it can be assumed that it is their success in acquiring resources and converting them into cytoplasm that controls the timing of their cell cycles. Cytoplasm is the sink for the bulk of the environmental resources.

Hypothesis: Hyperstructures regulate bacterial structure and the cell cycle

Biochimie, 1999
A myriad different constituents or elements (genes, proteins, lipids, ions, small molecules etc.) participate in numerous physico-chemical processes to create bacteria that can adapt to their environments to survive, grow and, via the cell cycle, reproduce.

The structure of bacterial cell cycle and age structure of bacterial populations.

Mikrobiolohichnyi zhurnal (Kiev, Ukraine : 1993), 1996
Study of synchronous and asynchronous cultures of Bacillus megaterium, Bacillus thuringiensis and Bacillus licheniformis has shown that the duration of chromosomal DNA replication (period C) is proportional to the generation time, and time between two cycles of the DNA replication (known as period I).
