Figure 6: Schematic representation of Arabidopsis cellular and biological processes with diurnal fluctuations in protein abundance or protein phosphorylation.
The inner three circles show terms of processes involving proteins with a maximal change in abundance during the day (yellow) or night (black). The outer circle show terms of processes involving proteins with changes in protein phosphorylation at the dark-to-light (D-L) transition (top) or light-to-dark (L-D) transition (bottom). The segments of each inner circle relative to ZT0 (day) or ZT12 (night) represent the approximate time interval in which proteins (ZT) and phosphoproteins (30 min before light or dark, 10 and 30 min after light or dark) involved in each process have their maximal change. The cellular and biological terms shown here were obtained by GO term enrichment of each protein and phosphoprotein cluster as outlined in Materials and Methods.
