Role of Filamentous Phage SW1 in Regulating the Lateral Flagella of Shewanella piezotolerans Strain WP3 at Low Temperatures
ABSTRACT Low-temperature ecosystems represent the largest biosphere on Earth, and yet our understanding of the roles of bacteriophages in these systems is limited. Here, the influence of theExpand

The Histone-Like Nucleoid Structuring Protein (H-NS) Is a Negative Regulator of the Lateral Flagellar System in the Deep-Sea Bacterium Shewanella piezotolerans WP3
ABSTRACT Although the histone-like nucleoid structuring protein (H-NS) is well known for its involvement in the adaptation of mesophilic bacteria, such as Escherichia coli, to cold environments andExpand

pSW2, a Novel Low-Temperature-Inducible Gene Expression Vector Based on a Filamentous Phage of the Deep-Sea Bacterium Shewanella piezotolerans WP3
ABSTRACT A low-temperature-inducible protein expression vector (pSW2) based on a filamentous phage (SW1) of the deep-sea bacterium Shewanella piezotolerans WP3 was constructed. This vector replicatedExpand

Multiple Mechanisms Are Involved in Repression of Filamentous Phage SW1 Transcription by the DNA-Binding Protein FpsR.
SW1 is the first filamentous phage isolated from a deep-sea environment. Nevertheless, the mechanism by which the SW1 genetic switch is controlled is largely unknown. In this study, the function ofExpand

Dynamic Modulation of DNA Replication and Gene Transcription in Deep-Sea Filamentous Phage SW1 in Response to Changes of Host Growth and Temperature
Little is known about the response of deep-sea virus and their relationship with their host towards environmental change. Although viruses are thought to play key roles in the deep-sea ecologicalExpand

Enhancing the Adaptability of the Deep-Sea Bacterium Shewanella piezotolerans WP3 to High Pressure and Low Temperature by Experimental Evolution under H2O2 Stress
ABSTRACT Oxidative stresses commonly exist in natural environments, and microbes have developed a variety of defensive systems to counteract such events. Although increasing evidence has shown thatExpand

The regulatory function of LexA is temperature-dependent in the deep-sea bacterium Shewanella piezotolerans WP3
The SOS response addresses DNA lesions and is conserved in the bacterial domain. The response is governed by the DNA binding protein LexA, which has been characterized in model microorganisms such asExpand
