Responses of wild-type and thermotaxis mutants to temperature steps as predicted by the pirouette hypothesis
| Stimulus | Wild-type | Cryophilic (ttx-3) | Thermophilic (unc-86) |
|---|---|---|---|
| Downstep | Turn | Run | Turn |
| Upstep | Turn | Turn | Run |
The term “turn” means an increase in the probability of the reversal and/or the omega states with a decrease in the probability of the forward state; conversely, “run” means an increase in the probability of the forward state with a decrease in the probability of the reversal and/or omega states.
