Fig. 6

Circos plot displaying the copy-number variable regions (CNVRs), R genes, and genes in the region between positions 3,507,000 and 4,107,000 bp on apple chromosome 2. The figure shows the region between 3,507,000 and 4,107,000 bp on chromosome 2 based on the ‘Golden Delicious’ v1.0p pseudohaplotype assembly [16]. This region contains resistance loci to apple scab, including Rvi4/Vh4 and. Rvi15/Vr2. Tracks from outside to inside are: (1) region ideogram ticks show the position in megabases (Mb), (2) trimmed standard deviation of segmentation scores plotted as a histogram with a y-scale from 0 to 0.6 (red bars indicate regions designated as CNVRs, blue bars represent all other regions), (3) the location of resistance genes, and (4) the location of genes other than resistance genes (yellow bars represent the location of these genes)
