The structure and evolutionary changes of the CENH3 locus. a Syntenic genes comprising the CENH3 locus. The species with important events, such as the formation of a syntenic group (rice), the emergence of the beta paralog (Stipa, Brachypodium), the inversion of the beta paralog (barley) and replacement of the 5′ marker gene (T. urartu) in their evolutionary history are given as examples. b The evolutionary changes in the size of the genes and intergenic spacers (ISs) comprising the CENH3 locus in Pooideae. Species not belonging to the tribe Triticeae, are marked with asterisks
