Flavonoid Abundance Across Cultivars and MS/MS Network: (a) Heatmap depicting the log10 average abundance of predicted flavonoids across sweet potato cultivars. BR Beauregard, KB Kotobuki, PP Purple Passion, AP All Purple Sweet Potato. Each flavonoid (row) is annotated with its most specific CANOPUS class, and clades of flavonoids with characteristic classifications and/or abundance patterns are numbered. (b) Venn Diagram depicting the presence/absence of predicted flavonoids across cultivars. The cultivar represented in the Orange set is Beauregard, and all other cultivars are represented in the Purple set. (c) MS/MS Molecular Network of CANOPUS-predicted and in house-predicted flavonoids. Node size and fill color represent flavonoid prediction methods. The largest nodes represent validated anthocyanins with a Cyanidin or Peonidin core (or ANT 16), medium-sized nodes (fill color of “Both”) were predicted as flavonoids by both methods, while small white nodes were predicted by in-house only, and small light green nodes were predicted by CANOPUS only. Gray nodes were doubly charged and thus not able to be predicted by CANOPUS. Border color represents grouping on the heatmap in (a).
