Figure 6. DEGs from anthocyanin, carotenoid and ABA biosynthesis. Schematic representation of bilberry anthocyanin biosynthetic pathway branching from phenylpropanoid biosynthesis (top) and representation of carotenoid biosynthetic pathway leading towards abscisic acid (ABA) biosynthesis and catabolism. DEGs from flavonoid, carotenoid-ABA pathway genes and selected TFs visualized as heatmap based on log2 fold changes obtained from light treatments against the control samples.
