Figure S2. Orthology map identified between Prunus and the other two Rosaceous genera based on whole genome sequence analysis. The lines link one to one orthologous region identified using Mercator program (Dewey 2007). Only the orthologous regions between the major orthologous chromosomes, as shown in Table 2, are depicted. The colors represent the 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 (Alekseyev and Pevzner 2009). A through H shows orthologous regions in Fragaria and Malus corresponding to those in Prunus chromosome 1 through 8, respectively.
