Crops of the Brassicaceae family display an amazing diversity of plant architectures; Brassica oleracea alone includes several morphotypes:broccoli,cabbage,cauliflower,kale,and brussel sprouts.The diploid Brassicas have genomes that contain ancient duplication event(s) that occurred after the divergence of the Brassica and Arabidopsis lineages around 14-20 million years ago.Genome duplications,diploidization,and subsequent functional diversification in diploid Brassicas have been recognized as the substrate leading to the phenotypic diversity exhibited by Brassica oleracea.
