An important result shown in Figure 1, but not mentioned in the manuscript, is that poplar (Malpighiales) is sister to cacao (Malvales) and Brassicales (Arabidopsis, papaya) in the malvid clade, and not the fabid clade (Fabales, Rosales). This result has been reported in other studies of nuclear gene phylogeny, and conflicts with the widely utilized APG3 classification that is predominantly based on plastid genes.
