Figure 2.

Protein sequence alignment of rosaceous MYB10 and known anthocyanin MYB regulators from other species. Arrows indicate specific residues that contribute to a motif implicated in bHLH co-factor interaction in Arabidopsis [44]. Box (A) a conserved motif [A/S/G]NDV in the R2R3 domain for dicot anthocyanin-promoting MYBs. Box (B) a C-terminal-conserved motif KPRPR [S/T]F for Arabidopsis anthocyanin-promoting MYBs [17].
