Flagella are extremely effective organelles of locomotion used by a variety of bacteria and archaea. Some bacteria, including Aeromonas, Azospirillum, Rhodospirillum, and Vibrio species, possess dual flagellar systems that are suited for movement under different circumstances. Swimming in liquid is promoted by a single polar flagellum. Swarming over surfaces or in viscous environments is enabled by the production of numerous peritrichous, or lateral, flagella. The polar flagellum is produced… Expand
Flagella by numbers: comparative genomic analysis of the supernumerary flagellar systems among the Enterobacterales
TLDR
Supernumerary flagellar loci are relatively common features across a broad taxonomic spectrum in the order Enterobacterales and are likely to play a role in the ecological success of members of this family and are postulate on their potential biological functions. Expand
A Complete Set of Flagellar Genes Acquired by Horizontal Transfer Coexists with the Endogenous Flagellar System in Rhodobacter sphaeroides
TLDR
This work found that the second flagellar system of R. sphaeroides can be expressed and produces a functional flagella, and suggests that Expression of the second set of flageLLar genes seems to be positively regulated under anaerobic growth conditions. Expand
Flagellar motility in bacteria structure and function of flagellar motor.
TLDR
This chapter surveys the current knowledge of the flagellar system, based mostly on studies from Salmonella, E. coli, and marine species Vibrio alginolyticus, supplemented with distinct aspects of other bacterial species revealed by recent studies. Expand
Bacterial lateral flagella: an inducible flagella system.
Flagella are complex surface organelles that allow bacteria to move towards favourable environments and that contribute to the virulence of pathogenic bacteria through adhesion and biofilm formationExpand
The bidirectional polar and unidirectional lateral flagellar motors of Vibrio alginolyticus are controlled by a single CheY species
TLDR
It is shown that both swimming and surface‐swarming of V.’alginolyticus involve chemotaxis and are regulated by a single CheY species, implying that CheY interacts with the two motors differently. Expand
Flagellar motor tuning - The hybrid motor in Shewanella oneidensis MR-1
Bacteria are exposed to constantly changing environments. An efficient way to navigate towards favourable conditions is flagella-mediated motility. Flagellar rotation is achieved by the bacterialExpand
Conversion of mono‐polar to peritrichous flagellation in Vibrio alginolyticus
TLDR
The results suggest that the role of FlhF is bypassed through a suppressor mutation which is not related to the flagellar genes. Expand
The cell biology of peritrichous flagella in Bacillus subtilis
TLDR
The cell biology of peritrichous flagella in the model bacterium Bacillus subtilis is explored by fluorescently labelling flagellar basal bodies, hooks and filaments and it is found that basal bodies are not positioned randomly on the cell surface, rather, basal bodies occupy a grid‐like pattern organized symmetrically around the midcell. Expand
In Situ Structures of Polar and Lateral Flagella Revealed by Cryo-Electron Tomography
TLDR
Cryo-electron tomography and subtomogram averaging are used to determine high-resolution in situ structures of polar flagella in Pseudomonas aeruginosa and peritrichous flageella in Salmonella enterica serovar Typhimurium, demonstrating substantial variation between flagellar systems in these organisms. Expand
Na(+)- and H(+)-dependent motility in the coral pathogen Vibrio shilonii.
TLDR
It is shown that V. shilonii produces lateral flagella when seeded on soft agar plates at concentrations of 0.5% or 0.6%, suggesting that this bacterium has a complex flagellar system, more complex possibly than other Vibrio species reported so far. Expand

TLDR
P phenotypic and genotypic analysis of mutant strains with defects in swimming motility coupled with primer extension analysis of flagellar and chemotaxis transcription provides insight into the polar flageLLar organelle, its assembly, and regulation of gene expression. Expand

TLDR
Mutants with single and multiple defects in flagellin genes were constructed in order to determine assembly rules for filament polymerization, and HAP mutants displayed new phenotypes, which were different from those of Salmonella typhimurium and most probably were the result of the filament being sheathed.

TLDR
The framework of the polar flagellar system of Vibrio parahaemolyticus is used to provide a synthesis of what is known about polar motility systems of the Vibrionaceae. Expand
Rhodospirillum centenum Utilizes Separate Motor and Switch Components To Control Lateral and Polar Flagellum Rotation
TLDR
It is demonstrated that R. centenum contains two sets of motor and switch genes, one set for the lateral flagella and the other for the polar flagellum, which indicates that the polar and lateral FliG, FliM, and FliN switch proteins are closely related and most likely arose as a gene duplication event. Expand
Lateral Flagellar Gene System of Vibrio parahaemolyticus
TLDR
This work describes the isolation of mutants with insertions in the structural and regulatory laf genes and the discovery of a gene encoding a MotY-like product, which previously had been associated only with the architecture of sodium-type polar flagellar motors. Expand
Polar and lateral flagellar motors of marine Vibrio are driven by different ion-motive forces
TLDR
Evidence that two distinct types of flagella powered by different energy sources are functionally active in one cell is reported, showing that the energy source for the polar flagellar motor of Vibrio para-haemolyticus is the sodium-motive force, whereas the lateral flageLLar motors are driven by the proton-Motive force.

Iron regulation of swarmer cell differentiation of Vibrio parahaemolyticus
TLDR
It is shown that a second signal, iron limitation, is also required for swarmer cell differentiation, and the control of differentiation by multiple environmental stimuli is discussed. Expand

TLDR
It is likely that the ability to express lateral flagella is a significant virulence determinant for the Aeromonas strains able to cause persistent and dysenteric infections in the gastrointestinal tract, but further work is needed to establish this. Expand
The sodium‐driven polar flagellar motor of marine Vibrio as the mechanosensor that regulates lateral flagellar expression
TLDR
Results indicate that marine Vibrio sense a decrease in the rotation rate of the polar flagellar motor as a trigger for Iaf induction, which is similar to that observed when viscosity was changed. Expand
Chemotactic control of the two flagellar systems of Vibrio parahaemolyticus
TLDR
It is concluded that the two flagellar organelles, which consist of independent motor-propeller structures, are directed by a common chemosensory control system. Expand
