| Abstract | The Brassicaceae family which includes Arabidopsis thaliana, is a natural priority for reaching beyond botanical models to more deeply sample angiosperm genomic and functional diversity. Here we report the draft genome sequence and its annoation of Brassica rapa, one of the two ancestral species of oilseed rape. We modeled 41,174 protein-coding genes in the B. rapa genome. B. rapa has experienced only the second genome triplication reported to date, with its close relationship to A. thaliana providing a useful outgroup for investigating many consequences of triplication for its structural and functional evolution. The extent of gene loss (fractionation) among triplicated genome segments varies, with one copy containing a greater proportion of genes expected to have been present in its ancestor (70 percent) than the remaining two (46 percent and 36 percent). Both a generally rapid evolutionary rate, and specific copy number amplifications of particular gene families, may contribute to the remarkable propensity of Brassica species for the development of new morphological variants. The B. rapa genome provides a new resource for comparative and evolutionary analysis of the Brassicaceae genomes and also a platform for genetic improvement of Brassica oil and vegetable crops. |
