Chantier qualité GA. International audience. In the past ten years, international initiatives have led to the development of large sets of genomic resources that allow comparative genomic studies between plant genomes at a high level of resolution. Comparison of map-based genomic sequences revealed shared intra-genomic duplications, providing new insights into the evolution of flowering plant genomes from common ancestors. Plant genomes can be presented as concentric circles, providing a new reference for plant chromosome evolutionary relationships and an efficient tool for gene annotation and cross-genome markers development. Recent palaeogenomic data demonstrate that whole-genome duplications have provided a motor for the evolutionary success of flowering plants over the last 50-70 million years.
