One of the most specialized functions of microtubules is found in the sperm tail or flagellum. Sperm flagella are essential for male fertility and thus for sexual reproduction.

An improved understanding of how flagella work may give nanotechnologists ideas about how to regulate tiny engines of their own creation. The flagellum is one of nature's smallest and most ...

Sperm are such great swimmers because of a slender flagellum that ripples like a living whip, trading brute force for ...

To build the machinery that enables bacteria to swim, over 50 proteins have to be assembled according to a logical and well-defined order to form the flagellum, the cellular equivalent of an ...

This flagellum-wrapping movement does not match any known forms of flagella-mediated motility and can be described as a third form of flagella-mediated motility.

Spatial arrangement of several flagellins within bacterial flagella improves motility in different environments. Nature Communications, 2018; 9 (1) DOI: 10.1038/s41467-018-07802-w ...

ALTHOUGH flagella movement or propulsion by means of a single flagellum is probably one of the first types of movement which came into existence, the fact remains that comparatively little is ...
