Figure 4.
Phase relationships of the rhythms of wild type (AMC149) and P28 after entrainment to LD cycles. These are composites showing the average trace for 60–200 colonies. Colonies were entrained to LD 11:11, LD 12:12 or LD 15:15 for four to five cycles and then transferred to LL at time 0; their circadian rhythms were monitored for the first cycle in LL. Data shown are after entrainment to LD 11:11 (A), LD 12:12 (B), and LD 15:15 (C). All data are from LL; shaded areas are the extrapolated night phases of the prior LD cycles. Ordinates are the luminescence intensities (left, for AMC149; right, for P28).
