Plant Genomics

Cereals and Crops

Comparison of the order of blocks within the different cereal chromosomes revealed that each cereal genome can be derived from the cleavage of a single structure, a hypothetical ‘ancestral’ genome, from which the genomes of present day cereals and grasses have evolved. The rice genome is one of the smallest among the cereals and grasses, and in 1995, we demonstrated that rice could be a model for cereals based on this ‘synteny’ because its genome can be divided into groups of genes - a series of genomic building blocks - from which the other larger cereal genomes can be constructed. The genome analysis will also help in our efforts for improvement of staple foods for yield and quality, which is a continuous process because neither the conditions of cultivation nor the genomes have to be targeted to the need of adaptations to a variety of biotic and abiotic stresses. Functional food components vary across the cereal crops and within different tissues of grain.
