The choreographed dynamics of bacterial chromosomes

open access: yesTrends in Microbiology, 2005
Despite decades of study, the exquisite temporal and spatial organization of bacterial chromosomes has only recently been appreciated. The direct visualization of specific chromosomal loci has revealed that bacteria condense, move and position their chromosomes in a reproducible fashion.

Bacterial Chromosome Segregation

Annual Review of Microbiology, 2002
▪ Abstract  Recent studies have made great strides toward our understanding of the mechanisms of microbial chromosome segregation and partitioning. This review first describes the mechanisms that function to segregate newly replicated chromosomes, generating daughter molecules that are viable substrates for partitioning.

The Bacterial Chromosome

Critical Reviews in Biochemistry and Molecular Biology, 2008
Bacteria represent the vast majority of biological diversity found on Earth. In this review, we focus on selected aspects of their genetic material, those providing insight into structural, functional, dynamic, and evolutionary aspects of their genomes. Bacterial chromosomes are far more dynamic than previously realized, and dozens of mechanisms giving

Replication of the bacterial chromosome

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1966
Abstract In this paper I shall confine myself to only one aspect of chromosome replication in bacteria: its control and co-ordination with growth and cell division. The nature of the problem to be considered is made clear by two features of chromosome replication in Escherichia coli, First, under conditions of rapid growth, involving ...

The structure and function of the bacterial chromosome

Current Opinion in Genetics & Development, 2005
Advances in microscopic and cell biological techniques have considerably improved our understanding of bacterial chromosome organization and dynamics. The nucleoid was formerly perceived to be an amorphous entity divided into ill-defined domains of supercoiling that are randomly deposited in the cell. Recent work, however, has demonstrated a remarkable

Investigating Bacterial Chromosome Architecture

2016
How is the bacterial chromosome organized within the bacterial cell? Over the last 60 years, a variety of approaches have been used to investigate this question. More recently, the parallel development of epifluorescence microscopy and genetic tools has enabled the direct visualization of the intracellular positioning of DNA sequences in live cells and

Bacterial chromosome origins of replication

Current Opinion in Genetics & Development, 1993
Bacteria regulate chromosomal replication from one specific origin. We compare the regulatory requirements, DNA structures, and biochemical properties of the prototypic Escherichia coli origin with those of evolutionarily distant Bacillus subtilis and Caulobacter crescentus origins.

Plasmids that mobilize bacterial chromosome

Plasmid, 1979
Abstract Cma can now be accepted as a common property of plasmids rather than one limited to a few, intensively studied examples. The mechanisms by which plasmids mobilize chromosome, in particular the role of plasmid integration into the bacterial chromosome and the part played by insertion sequences, are areas to which future interest should be ...

On the growth mechanism of the bacterial chromosome

Journal of Molecular Biology, 1963
Physical methods have been used to determine the number of growth points on the DNA of E. coli bacteria. The thymine analogue [14C]5-bromouracil was incorporated into DNA for varying short times. The labelled DNA was isolated with a molecular weight of 4 × 107. The density distribution of the radioactivity was investigated in CsCl gradients.
