  abstract = {{T}he complete sequence of {V}itis vinifera revealed that the rosid clade derives from a hexaploid ancestor. {A}t present, no analysis of complete genome sequence is available for an asterid, the other large eudicot clade, which includes the economically important species potato, tomato and coffee. {T}o elucidate the genomic history of asterids, we compared the sequence of an 800 kb region of diploid {C}offea genome to the orthologous regions of {V}. vinifera, {P}opulus trichocarpa and {A}rabidopsis thaliana. {W}e found a very high level of collinearity between around 80 genes of the three rosid species and {C}offea. {C}ollinearity comparisons between orthologous and paralogous regions indicates that (1) the {C}offea (and consequently all asterids) and rosids share the same hexaploid ancestor; (2) the diploidization process (loss of duplicated and redundant copies from the whole genome duplication) was very advanced in the most recent common ancestor of rosids and asterids. {F}inally, no additional polyploidization events were detected in the {C}offea lineage. {D}ifferences in gene loss rates were detected among the three rosid species and linked to the divergence in protein sequences.},
