Calcium Wave Velocity in Control Worms (N2 and glo-1) and itr-1 Mutants
| Allele | Ca2+ wave velocity | No. of waves observed | No. of waves with velocities too rapid to quantify |
|---|---|---|---|
| μm/s | |||
| N2/glo-1 | 33 ± 3 (10;28) | 30 | 2 |
| itr-1(sa73) | 10 ± 1a (6;16) | 16 | 0 |
| itr-1(sy327) | 64 ± 11b (6;11) | 22 | 11 |
| itr-1(sy290) | 91 ± 16c (5;6) | 13 | 7 |
Values are means ± SEM (n = number of intestines; number of waves). Images were acquired at 1-s intervals.
a
P < 0.05.
b
P < 0.01.
c
P < 0.001 compared with N2/glo-1 control animals.
