Regulation of the Caulobacter Cell Cycle

1975
This chapter focuses on the aquatic bacterium Caulobacter crescentus, which divides asymmetrically during each cell division cycle, yielding progeny cells that differ both structurally and functionally. The initially motile swarmer cell progeny sheds its flagellum and differentiates into a nonmotile stalked cell.

Spatial regulation in Caulobacter crescentus

Current Opinion in Microbiology, 2009
The proper positioning of regulatory proteins has a central role in the organization of both prokaryotic and eukaryotic cells. Important insights into the principles that underlie the spatial control of cellular processes have been gained from studies on the asymmetric bacterium C. crescentus.

The organization of the Caulobacter crescentus flagellar filament

Journal of Molecular Biology, 1989
The structural organization of the flagellar filament of Caulobacter crescentus, as revealed by immunoelectron microscopy, shows five antigenically distinct regions within the hook-filament complex. The first region is the hook. The second region is adjacent to the hook and is approximately 10 nm in length.

Cell differentiation in Caulobacter

Trends in Genetics, 1985
Abstract The generation of cellular asymmetry is the earliest step in a developmental program. This occurs at each Caulobacter cell division when structural and functional polarity is established in the predivisional cell. To do this, genetic mechanisms act to measure time and to organize cell constituents in three-dimensional space.

A flagellotropic bacteriophage and flagella formation in Caulobacter

Virology, 1976
Abstract A DNA-containing bacteriophage ∅Cp34 was isolated for Caulobacter . Phage ∅Cp34 consists of a prolate cylindrical head with a flexible and noncontractile tail. The host range is limited to Caulobacter crescentus and Caulobacter vibrioides .

Genetic Regulatory Hierarchy In Caulobacter Development

1990
Publisher Summary This chapter describes the Caulobacter regulatory cascade that controls flagellar morphogenesis and then compares the observed mechanisms to those that appear in other prokaryotic developmental systems. It also focuses on the freshwater Caulobacter crescentus, which is the best known species of the group.

Caulobacter its morphogenesis, taxonomy and parasitism

Antonie van Leeuwenhoek, 1955
Arguments have been forwarded in favour of the view that the stalk ofCaulobacter is part of the living cell. Accordingly the familyCaulobacteriaceae Henrici et Johnson should be set apart from bacteria growing on stalks made of secreted material. This should be achieved by elimination of the latter from the suborderCaulobacteriinae Breed, Murray et ...

The Genera Caulobacter and Asticcacaulis

1981
The genera Caulobacter and Asticcacaulis comprise dimorphic prosthecate bacteria which divide by asymmetric binary fission and whose cellular appendage (prostheca) is not involved in reproduction (Poindexter, 1964, 1974). In one species, A. biprosthecum, two lateral appendages are present on the prosthecate cell (Pate and Ordal, 1965; Pate, Porter, and

Development in Caulobacter crescentus

1992
Caulobacters are dimorphic bacteria, with a motile phase in which the cell body is flagellated, and a sessile stage, when the cell grows a stalk. Development involves the asymmetric division of the parent stalked cell to yield one flagellated swarmer cell and one stalked cell, followed by differentiation of the swarmer cell into a stalked cell.
