Ciliary adenosinetriphosphatase from a slow swimming mutant of Paramecium caudatum.
The slow swimming mutant (strain 11C 104), isolated from Paramecium caudatum, which swims at a speed about 70% of the wild type, is not different from the wild type (strain Kyky-1) in cell shape, density of cilia over the cell surface, and length of cilia. Cross-sectioned structures of the somatic cilia also do not give any difference between the mutant and the wild type. ATPase activities of c...
متن کاملThe relations between membrane potential and parameters of ciliary beat in free-swimming Paramecium caudatum.
It has been known for many years that electric currents flowing through a suspension of Paramecium modify the beating characteristics of the cilia in such a way that the organisms turn and move towards the cathode (Ludloff, 1895; Jennings, 1906). Jahn (1961) has accounted for this behaviour by supposing that current flows through the cell membrane and either enhances or reverses the normal cili...
متن کاملCalcium and microtubule sliding in ciliary axonemes isolated from Paramecium caudatum.
Microtubule sliding was induced in axonemes obtained from isolated cilia of Paramecium caudatum when they were exposed to a reactivating solution containing ATP after mild treatment with trypsin. Over a very wide range of concentrations (1 nM-4 mM), Ca2+ in the reactivating solution had no effect on the proportion of axonemes that disintegrated as the result of microtubule sliding. Also, the ve...
متن کاملLong-Term Tracking of Free-Swimming Paramecium caudatum in Viscous Media Using a Curved Sample Chamber
It is technically difficult to acquire large-field images under the complexity and cost restrictions of a diagnostic and instant field research purpose. The goal of the introduced large-field imaging system is to achieve a tolerable resolution for detecting microscale particles or objects in the entire image field without the field-curvature effect, while maintaining a cost-effective procedure ...
متن کاملBehavioral Mutants in PARAMECIUM CAUDATUM.
Mutants of Paramecium caudatum with abnormal swimming behavior or responses to cations were obtained by mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine. Some of the mutants, like pawn in P. tetraurelia, cannot swim backward and are called CNR. Seven independently obtained CNR mutants belonged to three complementation groups, designated as cnrA, cnrB and cnrC. Some characteristics of doubl...
