Quantitative analysis of data reveals axoneme and spoke periodicity.

, 2012
(A) Quantitative analysis of the axonemal repeat periodicity (Ax repeat, stained n = 77, frozen n = 45, FFT n = 5), PFR repeat (PFR-repeat, stained n = 299, frozen n = 34, FFT = 6), periodicity of axoneme-PFR interface densities (Ax-PFR repeat, stained n

Examination of rotational polarity of ciliary axoneme of brain ependymal cells and trachea epithelial cells by transmission electronic miscroscopy.

, 2014
Axoneme cross-sectional images were taken with a transmission electron microscope. The rotational polarity of each axoneme was evaluated by the angle of the line connecting the central pair.

The FC displaces the old flagellum axoneme and its position is fixed in relation to both axonemes.

, 2016
A) 3D reconstructions of the FC region show it in close proximity to microtubule doublets 3–5 in the new flagellum and microtubule doublets 1, 7–9 in the old flagellum both in high pressure frozen and chemically fixed samples.

The evolution of sperm axoneme structure and the dynein heavy chain complement in cecidomid insects.

, 2016
The 9+2 axoneme of cilia and flagella is specialized machinery aimed at the production of efficient, finely tuned motility, and it has been evolutionarily conserved from protists to mammals.

Lack of CCDC146, a ubiquitous centriole and microtubule-associated protein, leads to non-syndromic male infertility in human and mouse

eLife
From a cohort of 167 infertile patients suffering from multiple morphological abnormalities of the flagellum (MMAF), pathogenic bi-allelic mutations were identified in the CCDC146 gene.

Conserved and specific functions of axoneme components in trypanosome motility.

, 2006
The Trypanosoma brucei flagellum is unusual as it is attached along the cell body and contains, in addition to an apparently conventional axoneme, a structure called the paraflagellar rod, which is essential for cell motility.

Axoneme β-Tubulin Sequence Determines Attachment of Outer Dynein Arms

, 2008
SummaryAxonemes of motile eukaryotic cilia and flagella have a conserved structure of nine doublet microtubules surrounding a central pair of microtubules. Outer and inner dynein arms on the doublets mediate axoneme motility [1]. Outer dynein arms (ODAs)

Probing Dynein Motor Activity in the Intact Chlamydomonas Axoneme

, 2019
Eukaryotic flagella and cilia are long rod-like extensions of cells, which play a fundamental role in single cell movement, as well as in fluid transport. Flagella and cilia contain a highly evolutionary conserved mechanical structure called the axoneme.
