sentences:  For example, Poeae and Aveneae share a genetic marker with barley and 10 other members of Triticeae, whereas all 19 genera of Triticeae bear a wheat marker along with Bromeae.Genera within Triticeae contain diploid, allotetraploid and/or allohexaploid genomes, the capacity to form allopolyploid genomes varies within the tribe.In this tribe, the majority of diploid species tested are closely related to "Aegilops", the more distal members (earliest branch points) include "Hordeum" (Barley), "Eremian", "Psathyrostachys".
