Fig. 4.
Genes with similar function are coexpressed. (A) Examples of synchronous gene-expression profiles for histone genes, nucleus-encoded plastid RPGs, and genes involved in the chloroplast ETC. All expression estimates are normalized to 1 for the highest value. The green triangles indicate the timing of cell division. (B and C) Phase distributions over the diurnal cycle for genes belonging to chosen gene categories. Phase values are based on the algorithm JTK_CYCLE, with a cut-off rate BH.Q of 1 × 10−5. Functional categories shown are: histones, DNA replication, FAPs, RPGs, mitochondrial and chloroplast ETC, chlorophyll biosynthesis, CCM, cilia (flagellar proteome, including all FAPs).
