Axonemal bending stiffness of cilia implies single-motor forces above
Maximilian Kotz, Veikko F. Geyer, Benjamin M. Friedrich
The regular bending waves of cilia and flagella provide an iconic model system for the collective dynamics of molecular motors. The known regular arrangement of dynein motors in a…
Motor shot noise explains active fluctuations in a single cilium
Maximilian Kotz, Veikko F. Geyer, Benjamin M. Friedrich
Mesoscopic fluctuations reveal stochastic dynamics of molecules in both inanimate and living matter. We investigate how small-number fluctuations shape the collective dynamics of m…
Ciliary beating patterns map onto a low-dimensional behavioral space that accords with a simple mechanochemical model
Veikko Geyer, Jonathon Howard, Pablo Sartori
Biological systems are robust to perturbations at both the genetic and environmental levels. Yet, these same perturbations can elicit variation in behavior. The interplay between f…
Beat regulation in twisted axonemes
Pablo Sartori, Veikko Geyer, Jonathon Howard +1
Cilia and flagella are hairlike organelles that propel cells through fluid. The active motion of the axoneme, the motile structure inside cilia and flagella, is powered by molecula…
Dynamic curvature regulation accounts for the symmetric and asymmetric beats of Chlamydomonas flagella
Pablo Sartori, Veikko Geyer, Andre Scholich +2
Axonemal dyneins are the molecular motors responsible for the beating of cilia and flagella. These motors generate sliding forces between adjacent microtubule doublets within the a…
Motor regulation results in distal forces that bend partially disintegrated Chlamydomonas axonemes into circular arcs
V. Mukundan, P. Sartori, V. F. Geyer +2
The bending of cilia and flagella is driven by forces generated by dynein motor proteins. These forces slide adjacent microtubule doublets within the axoneme, the motile cytoskelet…
Cell body rocking is a dominant mechanism for flagellar synchronization in a swimming alga
Veikko Geyer, Frank Jülicher, Jonathon Howard +1
The unicellular green algae Chlamydomonas swims with two flagella, which can synchronize their beat. Synchronized beating is required to swim both fast and straight. A long-standin…
