Ancestral Chromosomal Blocks Are Triplicated in Brassiceae Species with Varying Chromosome Number and Genome Size

Popis výsledku v původním jazyce

The paleopolyploid character of genomes of the economically important genus Brassica and closely related species (tribe Brassiceae) is still fairly controversial.Here, we report on the 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 Fwere identified per haploid chromosome complement in Brassiceae specieswith 2n=14, 18, 20, 32, and 36. In high-polyploid (n more than 30) species Crambe maritima(2n=60), Crambe cordifolia (2n=120), and Vella pseudocytisus (2n=68), six, 12, and six copies of the analyzed block have been revealed, respectively. Homeologous regions resembled the ancestral structure of block F within the AK orwere altered by inversions and/or translocations. In two species of the subtribe Zillineae, two of the three homeologous regions were combined via a reciprocal translocation onto one ch
