Phylogenetic incongruences between horizontally transferred TGTT1 elements and trees of four Rosaceae species. a TGTT1 tree; the ML phylogenetic tree was based on intact sequences of 20 TGTT1 elements from 8 PbrTGTT1 (pink circles), 6 MdTGTT1 (blue squares), 4 PpTGTT1 (red circles) and 2 PmTGTT1 (green triangles). b Species tree; The red star indicates the recent whole-genome duplication event. The nucleotide sequence distances are indicated by the scales
