Phylogenetic tree of R2R3-MYB and R1R2R3-MYB (3R-MYB) subfamilies of <i>A</i>. <i>thaliana</i> and peach MYB proteins.

<p>The phylogenetic tree was constructed for R2R3-MYB and R1R2R3-MYB subfamilies using the sequences of 131 R2R3-MYB and R1R2R3-MYB proteins in <i>A</i>. <i>thaliana</i> and 256 MYB proteins of peach. The small red circles represent the 256 peach MYB proteins; the small green triangles represent the 126 R2R3-MYB subfamily and 5 R1R2R3-MYB subfamily proteins from <i>A</i>. <i>thaliana</i>. The English letters with Arabic numbers outside the large red circle indicate the names of each group of the peach R2R3-MYB and R1R2R3-MYB subfamilies. The red dotted line represents the initial or final boundary of each group of the peach R2R3-MYB and R1R2R3-MYB subfamilies.
