Homologous alignments of selected genome. Homologous alignments with V. vinifera (V) as a reference, V. vinifera chromosomes form the innermost circle, and their paralogous genes in synteny are linked curves. Exhibition the information of 3 plants about genomic paralogous, orthologous, and outparalogous relationship, each of the three sets of V. vinifera paralogous chromosomal regions have three orthologous copy in S. lycopersicum (A), forming 3×3=9 circles, and three orthologous copies in I. triloba (S) forming 3×3=9 circles. Finally, 21 circles are formed, each corresponding to figure 2f. The ch color scheme at the bottom is V. vinifera, if the genes of V. vinifera and S. lycopersicum, I. triloba are homologous, the lines of corresponding colors are displayed in the circle. Eu corresponds to the colors of seven chromosomes of the ancestor before the ECH event, and the innermost reference genome is the corresponding colors of Eu.
