The actin cytoskeleton of the mouse sperm flagellum is organized in a helical structure

Journal of Cell Science, 2018
Conception in mammals is determined by the fusion of a sperm cell with an oocyte during fertilization. Motility is one of the features of sperm that allows them to succeed in fertilization, and their flagellum is essential for this function ...

Multiple pathways impact the swarming motility of Pseudomonas fluorescens Pf0-1

Microbiology Spectrum
Swarming motility in pseudomonads typically requires both a functional flagellum and the production/secretion of a biosurfactant. Published work has shown that the wild-type Pseudomonas fluorescens Pf0-1 is swarming deficient due to a point mutation in ...

Contribution of microscopy for understanding the mechanism of action against trypanosomatids [PDF]

, 2018
Transmission electron microscopy (TEM) has proved to be a useful tool to study the ultrastructural alterations and the target organelles of new antitrypanosomatid drugs.

Bidirectional intraflagellar transport is restricted to two sets of microtubule doublets in the trypanosome flagellum

bioRxiv, 2018
Intraflagellar transport (IFT) is the rapid bidirectional movement of large protein complexes driven by kinesin and dynein motors along microtubule doublets of cilia and flagella.

Isolation of the Buchnera aphidicola flagellum basal body complexes from the Buchnera membrane.

PLoS ONE, 2021
Buchnera aphidicola is an intracellular bacterial symbiont of aphids and maintains a small genome of only 600 kbps. Buchnera is thought to maintain only genes relevant to the symbiosis with its aphid host.

TTC6-Mediated Stabilization of the Flagellum Annulus Ensures the Rapid and Directed Motion of Sperm

Cells, 2023
Sperm motility and structural integrity are essential for successful fertilization in vivo, and any hindrance of the correct assembly of the axoneme and peri-axonemal structures in the sperm flagellum can lead to fertility problems.

Analysis of the Movement of Chlamydomonas Flagella: The Function of the Radial-spoke System Is Revealed by Comparison of Wild-type and Mutant Flagella [PDF]

, 1982
The mutation uni-1 gives rise to uniflagellate Chlamydomonas cells which rotate around a fixed point in the microscope field, so that the flagellar bending pattern can be photographed easily .

Direction of flagellum beat propagation is controlled by proximal/distal outer dynein arm asymmetry

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance The motile flagellum/cilium is found across eukaryotic life, and it performs critical functions in many organisms including humans. A fundamental requirement for a motile flagellum is that it must undergo the appropriate waveform for its ...

Pea broth enhances the biocontrol efficacy of Lysobacter capsici AZ78 by triggering cell motility associated with biogenesis of type IV pilus

Frontiers in Microbiology, 2016
Bacterial cells can display different types of motility, due to the presence of external appendages such as flagella and type IV pili. To date, little information on the mechanisms involved in the motility of the Lysobacter species has been available ...

Tubulin Polymerization Promoting Proteins (TPPPs) of Aphelidiomycota: Correlation between the Incidence of p25alpha Domain and the Eukaryotic Flagellum

Journal of Fungi, 2023
The seven most early diverging lineages of the 18 phyla of fungi are the non-terrestrial fungi, which reproduce through motile flagellated zoospores. There are genes/proteins that are present only in organisms with flagellum or cilium.
