The gene structure and comparative analysis of the Rec8 homoeoalleles in wheat and its D-genome ancestor and the Rec8 orthologue in rice (OsRad21–4). a The gene structures and comparative analysis of the Rec8 orthologues in tetraploid wheat and rice. b The gene structure (right) and phylogenetic tree (left) of the Rec8 homoeoalleles in wheat and its D-genome ancestor. c Pairwise comparative analysis of the Rec8 homoeoalleles in wheat and its D-genome ancestor. The DNA sequence variation curves (red) were generated on a sliding window of 10 bp. The Y axes indicate the numbers of polymorphic nucleotides per 10 bp on the alignment
