evolution of wheat pdf

Wheat is the dominant crop in temperate countries being used for human food and livestock feed. Two of the most important traits in the evolution of bread BT ( )Tj tracked down the shifting genetics that have allowed the emergence of this potentially global threat to wheat crops (see the Perspective by Maekawa and Schulze-Lefert). In these geologically new environments, a group of plants that have symbiotic association with humans evolved from wild plants through domestication in both the Old and New Worlds.
