A review of New World Laemophloeus Dejean (Coleoptera: Laemophloeidae) : 1., species with antennal club of more than three antennomeres [PDF]

open access: yes, 2013
Five Neotropical species of Laemophloeus Dejean (s. str.) (Coleoptera: Laemophloeidae) with antennal clubs of more than three antennomeres are reviewed: L. buenavista Thomas, n.sp.; L. concinnus Thomas, n.sp.; L. germaini Grouvelle; L.

BOH1 cooperates with Polo-like kinase to regulate flagellum inheritance and cytokinesis initiation in Trypanosoma brucei

open access: yesJournal of Cell Science, 2019
Trypanosoma brucei possesses a motile flagellum that determines cell morphology and the cell division plane. Inheritance of the newly assembled flagellum during the cell cycle is controlled by the Polo-like kinase homolog TbPLK, which also regulates ...

Helical swimming motion driven by coordinated rotation of flagellar apparatus in marine bacterial cells

open access: yesJournal of Biomechanical Science and Engineering
The magnetotactic bacterium MO-1 possesses a pair of unique flagellar apparatuses. Each apparatus comprises seven flagella and 24 thin fibrils enclosed in a sheath.

Pseudomonas aeruginosa flagellum is critical for invasion, cutaneous persistence and induction of inflammatory response of skin epidermis

open access: yesVirulence, 2018
Pseudomonas aeruginosa, an opportunistic pathogen involved in skin and lung diseases, possesses numerous virulence factors, including type 2 and 3 secretion systems (T2SS and T3SS) and its flagellum, whose functions remain poorly known during cutaneous ...

A Flagellum-specific Calcium Sensor

open access: yesJournal of Biological Chemistry, 2005
The flagellar calcium-binding protein (FCaBP) of the flagellated protozoan Trypanosoma cruzi associates with the flagellar membrane via its N-terminal myristate and palmitate moieties in a calcium-modulated, conformation-dependent manner. This mechanism of localization is similar to that described for neuronal calcium sensors, which undergo calcium ...

Regeneration of the Eyespot and Flagellum in Euglena gracilis during Cell Division

open access: yesPlants, 2021
Cell division of unicellular microalgae is a fascinating process of proliferation, at which whole organelles are regenerated and distributed to two new lives.

Structure and behaviour of the sperm terminal filament [PDF]

open access: yes, 1982
Light- and electron-microscopic observations of Ciona and Lytechinus spermatozoa show a thin terminal filament at the distal end. The terminal filament is 5-6 microns long and contains the two central microtubules and a variable number of A-tubule ...

The Sheathed Flagellum of Pseudomonas stizolobii [PDF]

open access: yesJournal of General Microbiology, 1969
SUMMARY: Organisms of two strains of Pseudomonas stizolobii possessed one polar flagellum of unusual thickness. Negative-contrast staining and ultrathin sectioning indicated that the flagella are sheathed and are comparable in structure to the sheathed flagella described in Vibrio and Bdellovibrio.

Modelling Motility: The Mathematics of Spermatozoa

open access: yesFrontiers in Cell and Developmental Biology, 2021
In one of the first examples of how mechanics can inform axonemal mechanism, Machin's study in the 1950s highlighted that observations of sperm motility cannot be explained by molecular motors in the cell membrane, but would instead require motors ...

Inhibition and relaxation of sea urchin sperm flagella by vanadate [PDF]

open access: yes, 1980
Direct measurements of the stiffness (elastic bending resistance) of demembranated sera urchin sperm flagella were made in the presence of MgATP2- and vanadate.
