Figure 2.

(a) Phylogenetic relationships and times of divergence between A. splendens and other Gramineae species. (b) Expansions and contractions of gene families. Purple and yellow indicate expanded and contracted gene families respectively. (c) Clusters of orthologous and paralogous gene families in A. splendens and other Gramineae species. Only the longest isoform for each gene is shown. (d) Venn diagram of orthologous genes shared among the five species A. splendens, O. sativa, B. distachyon, P. edulis and A. tauschii. © Distribution of average synonymous substitution levels (Ks) between syntenic blocks.
