| Popis: | In scientific research, we often rely on well-established model systems to tackle important questions. In this context, extensive characterization of specific bacterial species such as Escherichia coli and Bacillus subtilis has provided a vast amount of knowledge that extends well beyond the biology of these two organisms. However, the bacterial world is large and extremely diverse, necessitating the development of additional models that complement the classical rod-shaped and symmetrically dividing systems. Caulobacter crescentus is a species that has met this need effectively, as its dimorphic lifestyle showcases distinctive features, including cellular asymmetry and differentiation during the cell cycle. Studying C. crescentus has reformed our understanding of bacterial intracellular organization, cellular development, and cell-cycle regulation. These findings have, in turn, stimulated studies in other bacteria, shedding light on how protein function and cell morphology can evolve and diversify. Studies in C. crescentus have also deepened our knowledge of other topics (e.g. cell mechanosensing, motility, and bacterial aging), while opening the door to biotechnological innovations. In this Primer, we provide some general background to this peculiar bacterium and highlight specific features that have contributed to its rise as a versatile bacterial model. This Primer is not meant to be exhaustive on any topic and is instead intended to provide a taste of the power of C. crescentus as a model system to explore a diverse range of topics. |
