Patterns of gene expressions of terpenoid biosynthesis. The network is compared among samples to indicate at least 2-fold changes of gene expressions (petals in red arrow and leaves in green arrow) during the petal developmental stages, with the highest expression level shown by the sample letter and variation less than 2-fold shown as ≈. The increases of more than 10 folds and 100 folds are indicated by double and triple up-pointing arrows, respectively. Dotted grey arrows show connections to other networks, and a dotted blue one indicates a suspected reaction. The major products are in bold. The enzymes are shown in blue rectangles with the EC numbers provided by the annotated final assembly, and ones in green rectangles were detected via individual blast searches.
