Figure 3.

Four cases of recurrent ctDNA transfer from the same regions of the wheat ct genome to different sites in the wheat mt genome. Ct and mtDNA segments involved in each event are drawn, respectively, in the top and bottom of each figure by their positions in the ct and mt genomes, which are shown by their ct- and mt-coordinates. Sequence homologies between the corresponding ct and mtDNA segments are shown in the scale drawn in the space between the ct and mt genomes and the transferred mtDNA segments are drawn in positions that fit their sequence homologies to the corresponding ctDNA segments. (a) Segments no. 7 and 8 originated from the ct-coordinates, 34262–34366. (b) Segments no. 10–13 originated from the ct-coordinates, 34918–36108. (c) Segments no. 18–20 originated from the ct-coordinates, 48013–48128. (d) Segments no. 50–53 originated from the ct-coordinates, 110973–111387.
