Fig. 1From: Functional identification of PsMYB57 involved in anthocyanin regulation of tree peonyThe R2 and R3 MYB repeats are highly conserved across all R2R3 MYB proteins in tree peony. The sequence logos of the R2 (a) and R3 (b) MYB repeats are based on full-length alignments of all R2R3 MYB proteins. The bit score exhibits the information content for each position in the sequence. Asterisks indicate the conserved tryptophan residues (Trp) in the MYB domainBack to article page
