The sequences available for specific wheat and barley genes, or gene fragments, have increased dramatically over the past five years. In 1998 there were only 4 expressed sequence tags (EST's) from wheat in the Genebank database and a total of 80 from the Triticeae (Langridge and Fincher 2003). In July this had risen to 426,000 for the Triticeae with 191,182 from wheat and 225,955 for barely (Langridge and Fincher 2003).
