Figure 2. Metabolically active sugar is a zeitgeber which acts differently to light.

Figure 2

a, CCA1:LUC rhythms (mean ± s.e.m) and b, period estimates in seedlings grown in continuous low light with the indicated sugar n =4. c, Phase response of CCA1:LUC rhythms to pulses of sucrose in continuous low light, (mean ± s.d.) n = 8. d, Change in normalised CCA1:LUC activity 3 h after sucrose or mannitol treatment in continuous low light, (mean ± s.d.) n = 4. e, CAB2:LUC rhythms in dark-adapted seedlings treated with sucrose or mannitol in continuous dark or transferred to continuous light, (mean ± s.e.m.) n = 4. f, Time to first circadian peak of CAB2:LUC after treatment with sucrose or light as in e, (mean ± s.d.) n = 4. ** P < 0.01 *** P < 0.001 by t-test.
