Oak genome orthologous and paralogous relationships. A. The distribution of Ks distance (scaled in MYA) values observed for the orthologous gene pairs identified between oak and Arabidopsis (light blue curve), poplar (red curve), grape (brown curve) and soybean (blue curve) genomes are illustrated as number of syntenic gene pairs (y-axis) per dating intervals (x-axis). Distribution peaks are highlighted with colored arrows. B. Schematic representation of the heterologous oak gene map illustrating the 1,825 orthologs identified between oak and grape and positioned on the 19 grape chromosomes. C. The distribution of Ks distance (scaled in MYA) values observed for the paralogous gene pairs identified for the oak (black bars), Arabidopsis (light blue curve), poplar (red curve), grape (brown curve), soybean (blue curve) genomes are illustrated as number of duplicated gene pairs (y-axis, left scale for oak/Arabidopsis/grape and right scale for poplar/soybean) per dating intervals (x-axis). The distinct rounds of whole genome duplication (p, α, β, γ) reported for the eudicot genome paleo-history are highlighted with grey boxes.
