Fig. 2: Genome evolution of A. majus.
a, Phylogenetic tree of angiosperm species including their divergence time on the basis of orthologues of single-gene families. The red star highlights the genome duplication in the A. majus lineage. The number in each node indicates Ma between two divergent branches. Green/red numbers indicate expansion and contraction gene families. A. trichopoda was used as an outgroup. Bootstrap values for each node are above 100%. b, Synteny blocks among chromosomes of A. majus, V. vinifera and S. lycopersicum. The numbers represent individual chromosomes. The selected syntenic gene numbers are more than 50 in each block. c, Density distributions of Ks for paralogous genes among A. majus, V. vinifera and S. lycopersicum. d, A Venn diagram of shared orthologues among four species of A. majus, S. lycopersicum, A. thaliana and O. sativa. Each number represents a gene family number shared among the genomes.
