Brachypodium distachyon genomics for sustainable food and fuel production

Grass crops are the most important sources of human nutrition, and their improvement is centrally important for meeting the challenges of sustainable agriculture, for feeding the world's population and for developing renewable supplies of fuel and industrial products. We describe the complete sequence of the compact genome of Brachypodium distachyon (Brachypodium) the first pooid grass to be sequenced. We demonstrate the many favorable characteristics of Brachypodium as an experimental system and show how it can be used to navigate the large and complex genomes of closely related grasses. The functional genomics and other experimental resources that are being developed will provide a key resource for improving food and forage crops, in particular wheat, barley and forage grasses, and for establishing new grass crops for sustainable energy production.
