Fig. 2: Betula platyphylla has not undergone any recent genome duplication.

A Blocks with more than 30 syntenic genes among Amborella trichopoda, Vitis vinifera, Prunus mume, Betula platyphylla, Populus trichocarpa, and Arabidopsis thaliana. Red lines show an example of one syntenic block in Amborella whose genome has not undergone gamma triplication matches up to three regions in Vitis, Prunus, and Betula, six regions in Populus, and 12 regions in Arabidopsis. B Pairwise Ks values of all homologous gene pairs from all synteny blocks in the B. platyphylla genome
