摘要
Abstract
As the genome sentences of Brassica rapa and Arabidopsis thaliana were released, the comparative research between species has been a focus in plant genomic research. A significant focus of comparative mapping in the Brassicaceae has been within the agronomical important species of the Brassica genera and between the Brassica crops and their well -characterized relative Arabidopsis thaliana. that explain the observed levels of gene duplication within the genomes. A-mounts of researches in plant genome organization have 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 . The correspondence between the A. thaliana and Brassica genomic regions is being exploited to QTL tagging, fine mapping, identifing and cloning genes for economically valuable traits.关键词
