Hydrodynamics Versus Intracellular Coupling in the Synchronization of Eukaryotic Flagella.
The influence of hydrodynamic forces on eukaryotic flagella synchronization is investigated by triggering phase locking between a controlled external flow and the flagella of C. reinhardtii. Hydrodynamic forces required for synchronization are over an order of magnitude larger than hydrodynamic forces experienced in physiological conditions. Our results suggest that synchronization is due inste...
متن کاملNoise and synchronization in pairs of beating eukaryotic flagella.
It has long been conjectured that hydrodynamic interactions between beating eukaryotic flagella underlie their ubiquitous forms of synchronization; yet there has been no experimental test of this connection. The biflagellate alga Chlamydomonas is a simple model for such studies, as its two flagella are representative of those most commonly found in eukaryotes. Using micromanipulation and high-s...
متن کاملElastohydrodynamic Synchronization of Adjacent Beating Flagella
It is now well established that nearby beating pairs of eukaryotic flagella or cilia typically synchronize in phase. A substantial body of evidence supports the hypothesis that hydrodynamic coupling between the active filaments, combined with waveform compliance, provides a robust mechanism for synchrony. This elastohydrodynamic mechanism has been incorporated into ‘bead-spring’ models in which...
متن کاملKinesin-related proteins in eukaryotic flagella.
To identify kinesin-related proteins that are important for ciliary and eukaryotic flagellar functions, we used affinity-purified, polyclonal antibodies to synthetic peptides corresponding to conserved sequences in the motor domain of kinesin (Sawin et al. (1992) J. Cell Sci. 101, 303-313). Using immunoblot analysis, two antibodies to distinct sequences (LNLVDLAGSE, 'LAGSE' and, HIPYRESKLT, 'HI...
متن کاملThe molecular motors of cilia and eukaryotic flagella.
Axonemal dyneins occur in two rows (as inner and outer arms) on each of the nine doublets. Axonemal dynein binds reversibly to the B-microtubule and has an ATP-insensitive anchorage to the A-microtubule of the adjacent doublet. The heavy chains have the form of globular heads and are responsible for chemo-mechanical transduction. The B-tubule-binding site is on a tenuous extension of the head. ...
