About Triticum aestivum

Triticum aestivum (bread wheat) is a major global cereal grain essential to human nutrition. Wheat was one of the first cereals to be domesticated, originating in the fertile crescent around 7000 years ago. Bread wheat is hexaploid, with a genome size estimated at ~17 Gbp, composed of three closely-related and independently maintained genomes that are the result of a series of naturally occuring hybridization events. The ancestral progenitor genomes are considered to be Triticum urartu (the A-genome donor) and an unknown grass thought to be related to Aegilops speltoides (the B-genome donor). This first hybridization event produced tetraploid emmer wheat (AABB, T. dicoccoides) which hybridized again with Aegilops tauschii (the D-genome donor) to produce modern bread wheat.

Wheat sequence search is no longer provided

As we now have a fully assembled and annotated bread wheat genome, there is no more need to provide a specfic wheat search service, which aimed to project wheat public sequences to closely related genomes (barley and Brachypodium). To search for wheat sequences, please use the generic search service provided in Ensembl Plants. This will return alignments in the context of the wheat genome, in place of the barley and Brachypodium genomes.
