Proportion of rhythmic genes increases with increasing transcription. All genes expressed in each organ were divided into five groups, namely, bottom 20%, 20–40%, 40–60%, 60–80%, and top 20% expressed genes, with the grouping depending on the mRNA expression level. Different colors represent the proportion of rhythmic genes in different groups. a Adrenal gland (n = 558). b Aorta (n = 434). c Brown fat (n = 1411). d Brainstem (n = 183). e Cerebellum (n = 232). f Heart (n = 1008). g Hypothalamus (n = 180). h Kidney (n = 2607). i Liver (n = 3874). j Lung (n = 2525). k Skeletal muscle (n = 347). l White fat (n = 366). The number of rhythmically expressed genes is noted in parentheses. Proportion of rhythmic genes was calculated by the number of rhythmically expressed genes in each group divided by the total number of rhythmically expressed genes in each organ
