Chromosomal structural variations among the Aj, Ar and An subgenomes in Brassica. The scales indicate the physical distance for the genome sequences (Mb) of Ar and An subgenomes and the genetic distance for Aj subgenome. a Inversion events detected among the Aj, Ar, and An subgenomes. The A10 chromosomes from the three subgenomes are shown. Inversion events that occurred in the other chromosomes are given in Additional file 4. The grey lines between the chromosomes indicate consistent alignment, and inversion events are indicated with blue lines. The letters in the body of the chromosomes indicate the large ancestral blocks. b Translocation events detected among the Aj, Ar, and An. The translocation events involving the Aj subgenome are shown with blue lines and the other translocation events are indicated with grey lines inside the circle
