Phylogeny of Poaceae. The topology and estimated times of divergence in million years (MY) are based on [65, 89–94]. Boxes indicate species accumulating benzoxazinoids [6, 17, 19, 20, 95]. In the Hordeum genus, benzoxazinoids are detected in some of the H-clade species (such as H. flexuosum and H. lechleri) and not in some species of the I-clade (such as H. vulgare and H. spontaneum) [17, 63, 96]. Bold branches indicate species included in our CYP71C phylogenetic study (only B. distachyon is included when considering the common branch B. distachyon/Lolium). Species / genus are in bold when a complete genome is available.
