Abstract
We have compared the structure of the genomes of rice and hexaploid bread wheat, which speciated more than 60 million years ago, by reciprocal mapping of DNA probes. Results indicate that many wheat chromosomes contain homoeologous genes and genomk DNA fragments in a similar order to that found on rice chromosomes. This conservation of gene order along chromosomes differing in DNA content by some 30–fold, may provide a basis for novel gene isolation strategies in wheat, one of the world's major food crop species.
