Figure 3: Duplicated and triplicated regions in the peach genome.

Each line links duplicated regions in peach. The seven different colors represent each linkage group of the eudicot ancestor that existed before hexaploidization. Peach genomic regions are colored by their orthology to the grape genome. The lines are colored by the paralogous regions, and the order of precedence when paralogous regions have different ancestral origins is indicated by the colors of TR1, TR2, TR3, TR4, TR5, TR6, TR7 and gray. Seven major triplicated regions (TR1–TR7) are shown. PC, Prunus chromosome.
