Figure 1.

Comparison of DNA-binding domains of R2R3-MYB transcription factor in H. undatus, B. vulgaris and A. thaliana. Sequence logos of the R2 (A,C,E) and R3 (B,D,F) repeats are based on conserved alignments from H. undatus (A,B), B. vulgaris (C,D) and A. thaliana (E,F). The overall height of each stack indicates the conservation of the sequence at the position, whereas the height of letters within each stack represents the relative frequency of the corresponding amino acid. Highly conserved tryptophan (W) and phenylalanine (F) residues are indicated by asterisks. The positions with different patterns between H. undatus, B. vulgaris and A. thaliana are indicated by arrows.
