Structure and phylogenetic relationship of dep with other WOX3 proteins. (a) Schematic diagram of dep. (b) Amino acid alignment of the highly conserved homeodomain and WUS box of dep and WOX3 orthologues from O. sativa, Z. mays, S. bicolor and A. thaliana. (c) Phylogenetic analysis showing the relationship of dep with other members of the WOX3 family. A. thaliana WOX10 was used as an outgroup. Bootstrap percentages are shown in the branching points.
