Fig. 4.

SNP frequencies and genome proportions of CANR4 satellites in 5x, 4x and 2x Rosa species. Pentaploid dogroses are indicated by red symbols, and tetraploid and diploid Rosa species are indicated by orange and blue symbols, respectively. The diploid representatives of the two early divergent subgenera are shown in green. Reads from individual clusters were mapped to the cluster consensus sequence and variants called at ≥20 % frequency. Increased sensitivity calls resulted in proportionally elevated SNP counts (Supplementary Data Table S2). On the y-axis, SNPs occurring in >20 % of reads; x-axis, genome proportion of the satellite.
