Coregulation of genes involved in basic transcription machinery during the night. BFC clusters from 2038 gene probes selected after PCA. Each colour corresponds to a biological process. Feature Number (Feat Num), BFC cluster number (BFC). Stars indicate two probes corresponding to two Feature Numbers associated to a single gene in the final annotation. Bottom right: The main BFC profiles and coefficients are shown. Note that clusters 61, 54, 111 and 67, clusters 29 and 92 as well as clusters 80 and 28 have almost identical profiles and for convenience only one profile (e.g. 61) is shown.
