Note: Only correlations with r > +0.5 or r < −0.5 and including at least one gene with significant daily rhythmicity are shown in this table. The following values were set to define the degree of correlation: data are moderately correlated if 0.5 < r < 0.79 and there is a strong correlation when r ≥ 0.80 which are highlighted in bold
