Bacteria display an abundance of cellular forms and can change shape during their life
cycle. Many plausible models regarding the functional significance of cell morphology have …

First isolated and classified in the 1960s, Caulobacter crescentus has been instrumental in
the study of bacterial cell biology and differentiation. C. crescentus is a Gram-negative …

An ability to sense and respond to changes in extracellular phosphate is critical for the
survival of most bacteria. For Caulobacter crescentus, which typically lives in phosphate …

Cellular differentiation is a fundamental strategy used by cells to generate specialized
functions at specific stages of development. The bacterium Caulobacter crescentus employs …

In recent decades, microbiologists have discovered an astounding disparity of prokaryotic
life. Our field has identified the most anciently divergent prokaryotic lineages, and we have …

Caulobacter crescentus adapts to phosphate starvation by elongating its cell body and a
polar stalk structure. The stalk is an extension of the Gram-negative envelope containing …

Bacterial cell shape is highly variable in the Alphaproteobacteria, suggesting that multiple
molecular mechanisms contribute to the generation of distinct morphologies. Although many …

CcrM is an orphan DNA methyltransferase nearly universally conserved in a vast group of
Alphaproteobacteria. In Caulobacter crescentus, it controls the expression of key genes …

ABSTRACT A suite of molecular sensory systems enables Caulobacter to control growth,
development, and reproduction in response to levels of essential elements. The bacterial …

Bacteria have a variety of mechanisms for adapting to environmental perturbations.
Changes in oxygen availability result in a switch between aerobic and anaerobic respiration …
