About Aegilops umbellulata

Aegilops umbellulata (2n = 2x = 14, UU genome) is the only diploid Aegilops species containing the U genome. Compared to the bread wheat A, B and D genomes, the U genome contains several large chromosome rearrangements and is a source of disease resistance genes that have been transferred into wheat. The genus Aegilops contains several grass species, commonly referred to as goatgrass. The genus comprises at least 23 diploid and polyploid species and six different genomes (C, D, M, N, S, and U). Aegilops species belong to the same tribe as the major cereal crops bread wheat (Triticum aestivum, 2n = 6x = 42; AABBDD genome), durum wheat (Triticum durum, 2n = 4x = 28; AABB genome) and barley (Hordeum vulgare, 2n = 2x = 14). The genus has thus been explored to increase genetic diversity of wheat via wide hybridization and chromosome recombination.
