Triticum aestivum L. (bread wheat)

Wheat is a cereal grain from the Family of Poaceae and it has been cultivated for more than 5000 years. Nowadays wheat is an important animal feed crop as well as a major contributer to world diet. Regarding produced quantity and cultivated area wheat ranks worldwide as number two after maize.

The bread wheat genome is hexaploid, contains 7 chromosomes and has a size of 17 Gb (which is ~5 times the human genome size). The growing sequence data and subsequent analyses are a valuable resource for comparative cereal genomics and help plant breeders to develop new improved crop varieties.
