Description	Comparative painting analysis of block F of the crucifer Ancestral Karyotype (AK; n=8), consisting of 24 conserved genomic blocks, in 10 species traditionally treated as members of the tribe Brassiceae. Three homeologous copies of block F were identified per haploid chromosome complement in Brassiceae with 2n=14, 18, 20, 32, and 36. In high-polyploid Crambe maritima (2n=60), C. cordifolia (2n=120), and Vella pseudocytisus (2n=68), 6, 12, and 6 copies have been revealed, respectively. In subtribe Zillineae, two of the three homeologous regions were combined via a reciprocal translocation onto one chromosome. Altogether, these findings provide compelling evidence of an ancient hexaploidization event and corresponding whole-genome triplication shared by the tribe Brassiceae. Only two homeologous copies of block F suggest a whole-genome duplication but not the triplication event in Orychophragmus violaceus (2n=24), and confirm its phylogenetic position outside the tribe Brassiceae.
