Abstract
The study of plant genome organization has benefited greatly from the application of comparative genetic mapping, which allows both the elucidation of chromosomal rearrangements resulting from speciation and the ability to transfer information and resources between species. A significant focus of comparative mapping in the Brassicaceae has been within the agronomically important species of the Brassica genera and between the Brassica crops and their well-characterized relative Arabidopsis thaliana. These studies have demonstrated the ghostly remnants of an hexaploid ancestor in the evolutionary past of the Brassica diploids that explain the observed levels of gene duplication within the genomes. Further, comparative mapping with A. thaliana has uncovered a segmental architecture of conserved ancestral blocks which can be replicated and rearranged to reflect the current genomes of all members of the Brassicaceae studied to date. The correspondence between the A. thaliana and Brassica genomic regions is being exploited to fine map, identify, and clone genes for economically valuable traits.
