The chromosomes of Prunus, Fragaria, and Malus, with the colors represent the origin from the 49 contiguous ancestral regions (CARs). The spaces with a black line represent chromosomal regions where the ancestral origin was not assigned. CARs that existed before the split of Prunus, Fragaria and Malus, were detected by MGRA (Multiple Genome Rearrangments and Ancestors) algorithm . The figure was drawn using R program (Hornik 2011).
