Comparative Cereal Genome Analysis-Reconstructing the Ancestral Cereal Genome
More than 60 million years ago speciation occurred giving rise to the cereals which eventually became the major crops grow today (Wolfe et al., 1989; Martin et al., 1989). In the last 50 years, many of these cereals have been studied largely in isolation, with little exchange of information between the breeders or scientists working on them. With the advent of plant Biotechnology, there is unlikely to be sufficient resources to study individual crops like maize, sorghum, rice, barley, rye, wheat, millet, sugarcane in any great detail, as compared to the resources devoted to the programmes on yeast, human and Arabidopsis. Yet in the next 50 years we will require as much cereal grain as has been consumed since the beginning of agriculture. Clearly it is going to be important to use the information generated from the study of these cereals more efficiently. Comparative genome analysis can provide just such a framework for collation of all this information.
