Fig. 8. Temperature shift experiments with the temperature-sensitive unc-54(e1157) allele. Shown is the average number of muscle arms extended by muscles 9 through 19 for the indicated genotypes. Counts for genotypes marked with an asterisk represent the average for muscles 9 to 15. For each muscle n=15, except for trIs30 (20°C) and trIs30 (20°C) hatchlings, for which n=30. The allele name is followed by either the temperature at which the animals were constitutively raised or a description of the time point (TP) (in hours) at which the animals were shifted to a different temperature. The coloured bars on the left represent the temperature at which animals were incubated during the indicated developmental times. Green, incubated at 15°C; red, incubated at 25°C; E, embryogenesis; L, larval development; A, adulthood. The error bars represents the standard error of the mean. Averages less than two arms per BWM are all significantly different than averages greater than two (P<0.001).
