A flagellum-specific chaperone facilitates assembly of the core type III export apparatus of the bacterial flagellum

open access: yesPLoS Biology, 2017
Many bacteria move using a complex, self-assembling nanomachine, the bacterial flagellum. Biosynthesis of the flagellum depends on a flagellar-specific type III secretion system (T3SS), a protein export machine homologous to the export machinery of the ...

The flagellum in malarial parasites

open access: yesCurrent Opinion in Microbiology, 2010
The malarial parasites assemble flagella exclusively during the formation of the male gamete in the midgut of the female mosquito vector. The observation of gamete formation ex vivo reported by Laveran (Laveran MA: De la nature parasitaire des accidents de l'impaludisme. Comptes Rendues De La Societe de Biologie.

The protein network of bacterial motility

open access: yesMolecular Systems Biology, 2007
Motility is achieved in most bacterial species by the flagellar apparatus. It consists of dozens of different proteins with thousands of individual subunits.

A short review on the morphology of Trypanosoma cruzi: from 1909 to 1999

open access: yesMemorias do Instituto Oswaldo Cruz, 1999
The morphology of Trypanosoma cruzi is reviewed since the initial description of Giemsa-stained preparations by Carlos Chagas until the most recent micrographs obtained with freeze-fracture techniques.

Length-dependent disassembly maintains four different flagellar lengths in Giardia. [PDF]

open access: yes, 2019
With eight flagella of four different lengths, the parasitic protist Giardia is an ideal model to evaluate flagellar assembly and length regulation. To determine how four different flagellar lengths are maintained, we used live-cell quantitative imaging ...

A chain mechanism for flagellum growth [PDF]

open access: yesNature, 2013
Bacteria swim by means of long flagella extending from the cell surface. These are assembled from thousands of protein subunits translocated across the cell membrane by an export machinery at the base of each flagellum. Unfolded subunits then transit through a narrow channel at the core of the growing flagellum to the tip, where they crystallize into ...

Flagellum Mutants of Chlamydomonas reinhardii [PDF]

open access: yesJournal of General Microbiology, 1972
Summary: Mutants blocked in different stages of flagellar development were isolated and examined by light and electron microscopy. Flagellum-less mutants had normal basal bodies but lacked the flagellar shaft and showed abnormalities in the transitional region.

Bend Propagation by a Sliding Filament Model for Flagella [PDF]

open access: yes, 1971
1. If active sliding occurs between flagellar filaments, as suggested for the sliding filament mechanism for muscular contraction, it will generate positive bending in one direction along the flagellum and negative bending in the opposite direction ...

Swarm behavior of self-propelled rods and swimming flagella [PDF]

open access: yes, 2010
Systems of self-propelled particles are known for their tendency to aggregate and to display swarm behavior. We investigate two model systems, self-propelled rods interacting via volume exclusion, and sinusoidally-beating flagella embedded in a fluid ...
