Homologous alignments of 10 legume genomes with V. vinifera as a reference

    Genomic paralogy, orthology, and outparalogy information within and among 10 legumes are displayed in 69 circles, each corresponding to an extant gene in Fig. 1b; The curved lines within the inner circle are formed by 19 grape chromosomes color-coded to correspond to the 7 ancestral chromosomes before the ECH. The short lines forming the innermost grape chromosome circles represent predicted genes, which have 2 sets of paralogous regions, forming another two circles. Each of the three sets of grape paralogous chromosomal regions has 2 orthologous copies in a legume with exception of soybean, which has 4. The resulting 69 circles were marked according to species by a capital letter, as defined in Fig. 1. Each circle has an underline colored as to its source plant corresponding to the color scheme in Fig. 1a and each circle is formed by short vertical lines that denote homologous genes, colored as to chromosome number in their respective source plant as shown in the inset color scheme.
