Abstract

In an effort to study the sensory-motor pathway of chemotaxis in Paramecium tetraurelia , I have generated mutants defective in their responses to chemicals. One mutant in particular, d4-530, is repelled by sodium acetate, which attracts normal paramecia by klinokinesis. The mutant is repelled by the mechanism of orthokinesis. To my knowledge, this is the first report of orthokinesis in chemotaxis of paramecia.
