Identification of parent-specific features (PSFs) in diploid Ae. tauschii and tetraploid wheat Tetra-Cantach. A. Alignment of an AT-specific probe with the target sequences in the D-genome of Ae. tauschii and AB-genomes of Tetra-Cantach. Homoeolog-specific mutation discriminating both the A- and B-genomes from the D-genome is shown in red. B. The scatter plot of observed versus expected d-statistics obtained for each PM probe. Expected values were obtained by permutations of dataset. Threshold Δ = 0.2 was applied for identifying significantly different oligonucleotide features between Ae. tauschii and Tetra-Cantach. C. Frequency distribution of the number of PSFs per probeset under various values of threshold Δ.
