The flagellum in many predatory flagellates is equipped with rigid hairs, which reverse the direction of thrust to generate a feeding current. We have discovered novel mechanism for generation hairy flagella, fundamentally different from slender body theory governing smooth flagella. show that generated at crests flagellar wave, thanks key role hydrodynamic interactions among effectively functi...

ABSTRACT The movement of ciliary membrane proteins is directed by transient interactions with intraflagellar transport (IFT) trains. green alga Chlamydomonas has adapted this process for gliding motility, using retrograde IFT motors to move adhesive glycoproteins in the flagella membrane. Ca2+ signalling contributes directly process, although uncertainty remains over mechanism through which it ...

Peritrichously flagellated bacteria swim in a fluid environment by rotating motors embedded the cell membrane and consequently multiple helical flagella. We present novel mathematical model of microswimmer that can freely run propelled flagellar bundle tumble upon motor reversals. Our is composed rod-shaped rigid body flagella randomly distributed over body. These go through polymorphic transfo...

This paper describes the production of supernumerary flagella by flagellates of Naegleria gniberi exposed to sublethal temperature shocks during the amoeba-to-flagellate transformation. When transformed at any constant temperature below 34 C, cells of N. gniberi strain NB-i may develop from 1 to 4 flagella, but biflagellate cells predominate and the average number of flagella per cell in these ...

Plesiomonas shigelloides is the unique member of the Enterobacteriaceae family able to produce polar flagella when grow in liquid medium and lateral flagella when grown in solid or semisolid media. In this study on P. shigelloides 302-73 strain, we found two different gene clusters, one exclusively for the lateral flagella biosynthesis and the other one containing the biosynthetic polar flagell...

Vaituzis, Z. (University of Maryland, College Park), and R. N. Doetsch. Flagella of Salmonella typhimurium spheroplasts. J. Bacteriol. 89:1586-1593. 1965.-The flagella of penicillin-induced spheroplasts of Salmonella typhimurium were examined by electron and light microscopy. The process of spheroplast formation was followed for a period of 20 hr from its inception. Flagella were found to be co...

Polar monotrichous and peritrichous flagella of Vibrio parahaemolyticus were isolated and purified separately. On hydroxylapatite column chromatography, the flagellins of polar monotrichous flagella were eluted with a higher concentration of phosphate than those of peritrichous flagella. Gel diffusion tests showed an antigenic difference between the flagellins of polar monotrichous and peritric...

During the short-term culturing of mouse spermatogenic cells, flagella were generated by round spermatids previously lacking tails. Unseparated germ cells were obtained by enzymatic treatments and round spermatids (greater than 90% pure) were purified by unit gravity sedimentation. As determined by Nomarski or phase-contrast microscopy, no cells had flagella immediately after isolation; flagell...

Vibrio parahaemolyticus has peritrichous flagella in addition to polar monotrichous flagella (1, 3, 4, 16, 17; E. Yabuuchi, M. Arita, Y. Takeda, and T. Miwatani, Jap. J. Microbiol., in press), and some differences in the characteristics of these two types of flagella have been reported. Polar monotrichous flagella are a normal type, whereas peritrichous flagella are an atypical, curly type (16;...
