Subfamilies

The BOP clade (sometimes BEP clade) is one of two major lineages (or clades) of undefined taxonomic rank in the grasses ( Poaceae), containing more than 5,400 species, about half of all grasses. Its sister group is the PACMAD clade; in contrast with many species of that group who have evolved C4 photosynthesis, the BOP grasses all use the C3 photosynthetic pathway. [1]

The clade contains three subfamilies from whose initials its name derives: [2] the bamboos (Bambusoideae); Oryzoideae (syn. Ehrhartoideae), including rice; and Pooideae, mainly distributed in temperate regions, with the largest diversity and important cereal crops such as wheat and barley. Oryzoideae is the earliest-diverging lineage, sister to the bamboos and Pooideae: [1] [3]
