Synthesis of Bacterial Flagella: Chromosomal Synchrony and Flagella Synthesis [PDF]
Journal of Bacteriology, 1969 Synchronous cultures of Bacillus subtilis 168 M were obtained from light-density spores germinated at 46 C and grown at 37 C. This procedure synchronizes both cell division and chromosome replication. The chromosome synchrony was demonstrated by using transformation to measure changes in marker frequency during the ...

Synthesis of Palladium Nanowires on Flagella Template for Electrochemical Biosensor Detection of microRNA-21. [PDF]
Biology (Basel)In recent years, the use of bacterial flagella as biomimetic templates has gained increasing attention in nanomaterial synthesis due to their unique structural and functional properties.

Physical mechanism reveals bacterial slowdown above a critical number of flagella. [PDF]
J R Soc InterfaceNumerous studies have explored the link between bacterial swimming and the number of flagella, a distinguishing feature of motile multiflagellated bacteria. We revisit this open question using augmented slender-body theory simulations, in which we resolve the full hydrodynamic interactions within a bundle of helical filaments rotating and translating ...

Energetics of synchronisation for model flagella and cilia [PDF]
Phys. Rev. E 103, 042419 (2021), 2021 Synchronisation is often observed in the swimming of flagellated cells, either for multiple appendages on the same organism or between the flagella of nearby cells. Beating cilia are also seen to synchronise their dynamics. In 1951, Taylor showed that the observed in-phase beating of the flagella of co-swimming spermatozoa was consistent with ...

σ28-dependent small RNA regulation of flagella biosynthesis
eLife, 2023 Flagella are important for bacterial motility as well as for pathogenesis. Synthesis of these structures is energy intensive and, while extensive transcriptional regulation has been described, little is known about the posttranscriptional regulation ...

Synchronization, slippage, and unbundling of driven helical flagella. [PDF]
PLoS ONE, 2013 Peritrichous bacteria exploit bundles of helical flagella for propulsion and chemotaxis. Here, changes in the swimming direction (tumbling) are induced by a change of the rotational frequency of some flagella.

A role for the membrane in regulating Chlamydomonas flagellar length. [PDF]
PLoS ONE, 2013 Flagellar assembly requires coordination between the assembly of axonemal proteins and the assembly of the flagellar membrane and membrane proteins. Fully grown steady-state Chlamydomonas flagella release flagellar vesicles from their tips and failure to

Branchial cilia and sperm flagella recruit distinct axonemal components. [PDF]
PLoS ONE, 2015 Eukaryotic cilia and flagella have highly conserved 9 + 2 structures. They are functionally diverged to play cell-type-specific roles even in a multicellular organism.
