Figure 5.—
Free-running periodic emergence of cry0 flies into adulthood. Late-developing cry0 cultures displayed periodic adult emergence in both DD and LL. The left-hand plots show adult-emergence profiles after application of a bandpass filter, which removed periodic components <4 and >40 hr (cf. Levine et al. 2002a). The other plots show analytical outcomes, the conventions for which (e.g., ordinate labels) are as in Figure 2. Wild-type cry+ cultures, which routinely eclose periodically in DD (e.g., Table 4), gave an eclosion profile in LL for which daily peaks damped out after ∼48 hr of being shifted to this condition.
