| Wild typea | dbl-1(ev580) b | |
|---|---|---|
| Pump rate (pumps/min) | 174 ± 39 | 179 ± 25 |
| Procorpus contraction length (msec) | 74 ± 14 | 79 ± 19 |
| Posterior bulb contraction length (msec) | 129 ± 28 | 118 ± 20 |
| Isthmus peristalsis length (msec) | 215 ± 38 | 210 ± 90 |
| % pumps followed by isthmus peristalsis | 2.5% | 10.5% |
a
Five N2 L1s were recorded for 29-30 sec each, and a total of 442 pumps were analyzed.
b
Five dbl-1(ev580) L1s were recorded for 20-30 sec each, and a total of 352 pumps were analyzed.
