Figure 3.

The ancestral core Brassicaceae karyotype (CBK) and the evolutionary history of Brassicaceae karyotypes.

Numbers in brackets indicate the conserved pPGs at each node (see supplementary Table 21). Rearrangement processes include nested chromosome insertions (NCI), end-to-end translocations (EET), and translocations (T), as well as paracentric (I^pa) and pericentric (I^pe) inversions. Black triangles indicate WGD events in Brassicaceae (At-α), and black sandglass-like symbols in karyotypes represent centromeres.
