Gamma triplication arises via two whole-genome duplications early in eudicot history, but the relative timing of these is unclear. Here, the authors report the genomes of Buxales and Trochodendrales and reject the hypothesis of gamma arising via inter-lineage hybridization between ancestral eudicot lineages.
