Oak genome orthologous relationships. A. Simplified phylogenic tree placing oaks among sequenced malvid (Arabidopsis, eucalyptus), fabids (peach, poplar) and basal rosid (grape) genomes. B. Distribution of Ks values (x-axis) for orthologous gene pairs between oak and malvids (Arabidopsis, eucalyptus: in blue), between oak and fabids (peach, poplar: in red) and between oak and grape (in green). Grape is considered to be the modern representative of the ancestral eudicot genome. C. Distribution of peach gene models (blue curve) and 9,549 orthologous gene pairs with oak (red curve) along the 8 peach chromosomes. Peach chromosomes are illustrated as a mosaic of 7 colours highlighting the features of the ancestral eudicot chromosome (A1, A4, A7, A10, A13, A16, A19) as in [19].
