Properties of PJF and of spontaneous Ca²⁺ sparks in WT and MO-injected larvae

Fiber property	WT	Morphant
PJF/JF ratio (mean ± SD)	0.79 ± 0.14a (n = 7)	0.03 ± 0.03b (n = 10)
Spark frequency (sarcomere−1 s−1 (mean ± SEM)	0.083 ± 0.018c (n = 42)	0.001 ± 0.001d (n = 39)

For both properties, the morphant values differ from the WT values at P < 0.01.

^aThree experiments, 7 fish, 410 triads from 70 fibers.

^bFour experiments, 10 fish, 420 triads from 100 fibers.

^cFour experiments, 42 cells.

^dFour experiments, 39 cells.
