Temperature-Sensitive Pawns: Conditional Behavioral Mutants of Paramecium aurelia

Sheng-Yung Chang 1 and Ching Kung 1

1 Department of Biological Sciences, University of California, Santa Barbara 93106

"Pawns" are mutants of Paramecium aurelia in which the process of calcium activation during membrane excitation is genetically impaired, with a corresponding loss of avoiding reactions. Mutants are selected that behave normally when grown at 23°C but as pawns at 35°C. The normal excitation can now be disrupted and restored in the same strain at will.
