Taxonomic relationships of fi ve Brassicaceae species. Phylogenetic tree summarizing the taxonomic relationships among fi ve Brassicaceae species with fully sequenced genomes, plus Carica papaya from the order Brassicales used as out-group. Branch lengths refl ect evolutionary time (in millions of years). Divergence times are shown at internal nodes. For the timing of these events, as well as for the tree topology, we used estimates from [ 16 ]. The history of WGDs is mapped onto the tree, with the four-pointed and six-pointed stars representing WGDs and triplications, respectively. The positions of these events are not meant to refl ect their precise timings of occurrence

... Target Genomes" enter the name of the genomes to be searched. In this case, we will choose a representative set of fi ve Brassicaceae species with whole genome sequences avail- able ( A. thaliana , A. lyrata , Brassica rapa , Capsella rubella , and Thellungiella parvula ), plus Carica papaya , belonging to the order Brassicales, as an outgroup (Fig. 2 ).
