Iwatsuki, T. Hirano] To understand the role of calcium ions in thigmotaxis inParamecium caudatum, the effects of caffeine, ruthenium red and lanthanum (LaCl3) on thigmotaxis were examined. Thigmotaxis in the CNR mutant, which lacks voltage-dependent Ca2+-channels in the ciliary membrane, was also examined. Ruthenium red and LaCl3 suppressed thigmotaxis inP. caudatum, while caffeine enhanced it. The CNR mutant showed hardly any thigmotaxis. It can be thought that an increase in Ca2+ influx and the intraciliary concentration of Ca2+ ions induces thigmotaxis inParamecium.
