Shared metabolic pathways among glycolysis, the OPPP, and the Calvin cycle, as well as the circadian patterns of genes for their enzymatic steps

Overview of shared metabolic pathways among glycolysis, the OPPP, and the Calvin cycle, as well as the circadian patterns of genes for their enzymatic steps. (A) A diagram of the metabolic pathway which includes overlapping reactions from glycolysis, the OPPP, and the Calvin cycle and overlays the timing of circadian gene expression onto each pathway. Genes exclusively part of the OPPP generally peak at dusk (red), whereas genes exclusively part of the Calvin cycle generally peak at dawn (green). Additionally, glycogen metabolism (gray box) shows a similar pattern in which anabolic genes peak at dawn and catabolic genes peak at dusk. (B) The table indicates the probability of observing the set of coincident peak times strictly by chance. P values were calculated using Fisher’s exact test. 6PG, 6-phosphogluconate; 6PGL, 6-phosphogluconolactone; ADP-Glc, ADP-glucose; DHAP, dihydroxyacetone phosphate; E4P, erythrose-4-phosphate; F1,6P, fructose-1,6-bisphosphate; F6P, fructose-6-phosphate; G1,3P, 1,3-bisphosphoglycerate; G1P, glucose-1-phosphate; G3P, 3-phosphoglycerate; G6P, glucose-6-phosphate; GAP, glyceraldehyde-3-phosphate; R5P, ribose-5-phosphate; Ru5P, ribulose-5-phosphate; RuBP, ribulose-1,5-bisphosphate; S1,7P, sedoheptulose-1,7-bisphosphate; S7P, sedoheptulose-7-phosphate; X5P, xylose-5-phosphate.
