Figure 2. Gene family and genome evolution of Pse. libanotica (A) The left panel includes the estimation of divergence time of Pse. libanotica and O. sativa , B. distachyon , T. aestivum , A. tauschii , T. durum ,T. dicoccoides , T. urartu , S. cereale , H. vulgare , Z. mays and A. thaliana . The right panel displays the distribution of single-copy, multiple-copy, unique and other orthologues. (B) Distribution of the Ks values of the best reciprocal BLASTP hits in the genomes of Pse. libanotica (Pse),D. glomerata (Dgl) and B. distachyon (Bdi). (C) The number of gene families shared among seven Triticeae species genomes shown in Venn diagrams.
