Figure 1.
Twenty-four hour expression profiles of clock genes in the liver of salmon parr acclimated to LD photoperiod.
Results are displayed in relation to Zeitgeiber time (ZT), where ZT 0 is the onset of light. Gene expression data is displayed as the percentage of the mean ± SEM and includes the spread of the data. The presence of a cosine wave denotes a significant circadian rhythm by acro analysis. The grey bar at the bottom of the graph represents the dark period. The presence of different letters represents statistically significant differences between samples by ANOVA and Tukey’s test (P<0.05).
