Triticeae

The tribe Triticeae within the subfamily Pooideae of grasses includes genera with many domesticated species. Major crop genera found in this tribe include wheat (See Wheat taxonomy), barley, and rye; crops in other genera include some for human consumption and others used for animal feed or rangeland protection. Among the world's cultivated species, this tribe has some of the most complex genetic histories. An example is bread wheat, which contains the genomes of three species, only one of them originally a wheat Triticum species. Seed storage proteins in the Triticeae are implicated in various food allergies and intolerances.
