In-phase and anti-phase flagellar synchronization by waveform compliance and basal coupling
We present a theory of flagellar synchronization in the green alga Chlamydomonas , using full treatment of flagellar hydrodynamics and measured beat patterns.

We investigate difference in the chemotactic behavior between peritrichous bacteria (Salmonella typhimurium SJW1103) and monotrichous bacteria (Vibrio alginolyticus YM4).

Bending Moments in Free-Swimming Flagella [PDF]
The bending of a flagellum, such as the flagellum which forms the tail of a sea-urchin spermatozoon, is the result of active mechanochemical processes occurring within the flagellum itself, which cause it to bend actively throughout its length (Gray ...

Flagella bending affects macroscopic properties of bacterial suspensions
To survive in harsh conditions, motile bacteria swim in complex environment and respond to the surrounding flow. Here we develop a PDE model describing how the flagella bending affects macroscopic properties of bacterial suspensions.

Inhibition and relaxation of sea urchin sperm flagella by vanadate [PDF]
Direct measurements of the stiffness (elastic bending resistance) of demembranated sera urchin sperm flagella were made in the presence of MgATP2- and vanadate.

Doing more with less: the flagellar end piece enhances the propulsive effectiveness of human spermatozoa [PDF]
Spermatozoa self-propel by propagating bending waves along a predominantly active elastic flagellum. The organized structure of the "9 + 2" axoneme is lost in the most-distal few microns of the flagellum, and therefore this region is unlikely to have the ability to generate active bending; as such it has been largely neglected in biophysical studies ...

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 ...

Dual flagellar systems have been described in several bacterial genera, but the extent of their prevalence has not been fully explored. Bradyrhizobium diazoefficiens USDA 110T possesses two flagellar systems, the subpolar and the lateral flagella.

Irradiation of Sperm Tails by Laser Microbeam [PDF]
1. Sea-urchin and starfish sperm tails were irradiated at pre-selected points along the flagellum and at pre-selected phases of the beat cycle by means of a pulsed ruby laser microbeam. Multiple-exposure dark-field photomicrographs were taken immediately

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 ...
