Prokaryotes use a wide variety of structures to facilitate motility. The majority of research to date has focused on swimming motility and the molecular architecture of the bacterial flagellum. While intriguing questions remain, especially concerning the specialized export system involved in flagellum assembly, for the most part the structural components and their location within the flagellum and function are now known. The same cannot be said of the other apparati including archaeal flagella…

Flagellar glycosylation - a new component of the motility repertoire?
TLDR
This review focuses on the structural diversity in flagellar glycosylation systems and demonstrates that as a consequence of the unique assembly processes, the type of glycosidic linkage found on archaeal and bacterialflagellins is distinctive.
Identification of Archaea-specific chemotaxis proteins which interact with the flagellar apparatus
TLDR
Results demonstrate that, in the archaeal domain, previously unrecognized archaea-specific Che proteins are essential for relaying taxis signaling to the flagellar apparatus.
Flagellar motility in bacteria structure and function of flagellar motor.
Recent Advances in the Structure and Assembly of the Archaeal Flagellum
TLDR
Questions about the evolution of these systems and possible inclusion of archaeal flagella into this surface complex family are raised.
Bacterial and archaeal flagella as prokaryotic motility organelles
TLDR
The properties and molecular organization of flagella—the bacterial and archaeal motility organelles—are reviewed and similarity is supposed between flagellin and actin with regard to their polymeric forms (BFF and F-actin).
Flagellation and Chemotaxis
TLDR
It is expected that the continued study of archaeal flagellation and chemotaxis will lead to novel discoveries about these structures and processes in archaea, and these may in turn lead to insights into the understanding of bacterialChemotaxis and type IV pili assembly, structure, and function.
Phylogenomics of the archaeal flagellum: rare horizontal gene transfer in a unique motility structure
TLDR
It is shown that the components of the archaeal flagellar system have not been frequently transferred among archaealing species, indicating that gene fixation following HGT can also be rare for genes encoding components of large macromolecular complexes with a structural role.
Type IV pili: paradoxes in form and function.
Pili and flagella biology, structure, and biotechnological applications.
Stepwise formation of the bacterial flagellar system
TLDR
These results show that core components of the bacterial flagellum originated through the successive duplication and modification of a few, or perhaps even a single, precursor gene.

The archaeal flagellum: a different kind of prokaryotic motility structure.
TLDR
The archaeal flagellum is a unique motility apparatus distinct in composition and likely in assembly from the bacterial flageLLum, and techniques to isolate flagella with attached hook and anchoring structures have been developed.
Flagellar assembly in Salmonella typhimurium
TLDR
Out of more than 40 genes required for construction of a fully functional flagellum in Salmonella typhimurium, only 18 gene products have been identified in the mature structure.

TLDR
Twitching motility is a flagella-independent form of bacterial translocation over moist surfaces that is important in host colonization by a wide range of plant and animal pathogens, as well as in the formation of biofilms and fruiting bodies.
Spirochete periplasmic flagella and motility.
TLDR
To better understand spirochete motility on a more molecular level, the proteins and genes involved in motility are being analyzed and unique aspects have already become evident.

TLDR
Studies on the gliding bacterium Myxococcus xanthus suggest that two independent gliding machineries, encoded by two multigene systems, operate in this microorganism, suggesting that the two motors found in this bacterium can be regulated to result in coordinated multicellular movements.
