Figure 2. Glycerol biosynthesis.

Figure 2

Fold changes between each sampling date through the winter for transcripts annotated as key enzymes in the biosynthetic pathway for glycerol: glycerol-3-phosphate dehydrogenase (G3PDH, KB741112.1) and glycerol kinase (GK, KB740969.1). An asterisk indicates a significant fold change within the two time points measured within each sampling period (Bonferroni adjusted p-value < 0.001). The diagram on the right illustrates a subset of the glycerol biosynthetic pathway (modified with permission from Fraser, 2011) showing the location G3PDH and GK as the enzymes that catalyze the steps immediately preceding the production of glycerol. Metabolites are shown in ovals: dihydroxyacetone phosphate (DHAP), glycerol-3-phosphate (G3P), glyceraldehyde (GA); enzymes are shown in rectangles: glycerol-3-phosphate dehydrogenase (G3PDH), glycerol kinase (GK), alcohol dehydrogenase (ADH).
