The core clock remains rhythmic regardless of age. a Expression of the 39 genes that maintained oscillations across all age groups. b Functional categorization of the GO terms for the 39 genes whose diurnal expression did not change with age. Genes related to diurnal rhythm-related function (shaded blue) or other biosynthetic processes (shaded white). c Relative expression at both times across all age groups for a subset of genes that did not change with age (FDR < 0.05)
