Abstract

Specific objectives are to make physical map of 3A short and long arms, anchor to a genetic map, and sequence 48 BACs.

Wheat occupies more arable land (17% of all crop area) and possesses more market share ($31 billion) than any other cereal crop. It is a staple food for 40% of world's population and provides 20% of the calories consumed. The world wheat yield must increase from the current 500M to 1 billion tons to feed 9 billion people by 2030. The yield per unit land area must be increased in an economically and environmentally sustainable manner. It is widely accepted that genome mapping and sequence information is essential for achieving significant step changes in the manipulation of crops by breeding to improve yield, agronomic and quality attributes. Yet wheat genome is the largest among crop plants and presents a challenge in terms of cost and feasibility. In this proposal, a team of scientists affiliated with the International Wheat Genome Sequencing Consortium (IWGSC) will explore a novel approach for constructing an integrated genetic and physical map of wheat chromosome 3A as a sequence ready template for deciphering the hereditary blueprint of 5400 genes. Project resources will be freely shared with the wheat genetics community. This proposal will contribute to the USDA CSREES broad goals of (1) Enhancing opportunities for agriculture producers and (4) Improving the nation's nutrition and health. The wheat physical map will lead to the discovery of new genes controlling disease resistance, grain quality, yield, and identification of genes for antioxidant compounds such as flavonoids, xanthophylls and those involved in lipid metabolism that contribute to human health.
