Figure S1. Distribution of 17-mers in raw sequence data from the M. baccata genomes.
Figure S2. Genetic and physical maps of M. baccata genome.
Figure S3. Indication of relationship between genetic distance and physical distance for the M. baccata genome chromosomes.
The left blue bars indicate pseudomolecules, and the right green bars represent linkage groups corresponding to 17 chromosomes. The light green blocks indicate ordered regions and markers, and the dark green blocks and lines represent unordered but matched scaffolds to the genetic map.
Figure S4. Stacked bar plots of the categories of BUSCO groups searched in M. baccatagenome and other Rosaceae plants.
Different color represents complete single copy, complete duplicated copy, fragmented and missing BUSCOs respectively. (Mb, Malus baccata; Md, Malus domestica; Pb, Pyrus bretschneideri; Pp, Prunus persica; Fv, Fragaria vesca)
Figure S5. The distribution of the distance between SNPs in M. baccata genome.
Figure S6. SNP frequency per gene in M. baccata genome.
Figure S7. Venn diagram of genes with homology or functional classifications by different methods.
Figure S8. Histogram of Ka/Ks values for orthologous genes from M. baccata and M. domestica.
Figure S9. Divergence time between 10 species.
Figure S10. Synteny analyses among Rosaceae species.
The numbers of nodes represent divergence time in MYA (million years ago). The red node represents known divergence time range. The polygonal star represents WGD invent according to previous studies.
