Single copy nuclear genes improve phylogenetic resolution in the Brassicaceae. A single most-parsimonious tree was found from combined analysis of complete data-matrix containing genes At2 g32520, At2 g13360, and At5 g23290 (L = 961, consistency index = 0.774, retention index = 0.529). Bootstrap values are shown above branches. Note that individual gene trees gave similar topologies. The phylogeny is consistent with published phylogenies using more taxa and other molecular markers. Bootstrap values from Beilstein et al., 2006 are shown below branches.
