Frontiers in Microbiology, 2020 Flagella are bacterial organelles of locomotion. Their biogenesis is highly coordinated in time and space and relies on a specialized flagellar type III secretion system (fT3SS) required for the assembly of the extracellular hook, rod, and filament parts

Calcium-induced asymmetrical beating of triton-demembranated sea urchin sperm flagella [PDF]
, 1979 Asymmetrical bending waves can be obtained by reactivating demembranated sea urchin spermatozoa at high Ca2+ concentrations. Moving-film flash photography shows that asymmetrical flagellar bending waves are associated with premature termination of the ...

New Vistas in the Biology of the Flagellum—Leishmania Parasites
Pathogens, 2022 Like other kinetoplastid protozoa, the flagellum in Leishmania parasites plays central roles throughout the life cycle. Discoveries over the past decade have begun to elucidate flagellar functions at the molecular level in both the insect vector stage ...

Dynamics of a bacterial flagellum under reverse rotation [PDF]
, 2016 To initiate tumbling of an E. coli, one of the helical flagella reverses its sense of rotation. It then transforms from its normal form first to the transient semicoiled state and subsequently to the curly-I state.

Uncoupling flagellum formation and maintenance [PDF]
Cilia, 2015 Objective The role of Intraflagellar transport (IFT) in the construction of cilia and flagella is well established in numerous species. In contrast, its involvement in flagellum maintenance has only been shown in Chlamydomonas. Here, the protist Trypanosoma brucei was used as a model to investigate the role of IFT in flagellum maintenance.

The Role of the Flagellar Protein FlgJ in the Virulence of Brucella abortus
Frontiers in Cellular and Infection Microbiology, 2020 Brucella abortus is a facultative intracellular pathogen that causes a zoonosis called brucellosis. This disease leads to abortion and infertility in cattle, and diverse complications in humans. B. abortus is a successful intracellular bacterium that has

Mechanisms of flagellum construction and maintenance [PDF]
Cilia, 2015 Cilia and flagella are cylindrical organelles that protrude at the surface of numerous eukaryotes including most human cells. They are composed, from base to tip, of the basal body (9 triplet microtubules), the transition zone (TZ, 9 doublet microtubules) and the axoneme (9 doublet microtubules ± 2 central microtubules).
