Fig. 3: Alignment of the PhAN4MD protein sequence with other anthocyanin-related R2R3-MYB transcription factors.

The conserved R2 and R3 domains are indicated by solid lines. Vertical arrows indicate the bHLH-interacting motif ([D/E]Lx2[R/K]x3Lx6Lx3R) in the R3 domain. Red boxes indicate different residues between the AN4V30 and AN4MD protein sequences
