Figure 2. Phylogenetic tree and amino acid sequence alignment among the R2R3 MYB and R3 MYB regions.

Figure 2

A. Neighbor joining phylogenetic tree of the amino acid sequence of the R2R3 MYB regions (AtWER, AtGL1, AtPAP1, GhMYB2, GhMYB25, GhMYB25-like, GhMYB36, GhMYB109) and R3 MYB regions (AtETC1, AtTRY, AtCPC, GhTRY, GhCPC). B. Sequence alignment of R2R3 MYB and R3 MYB members using ClustalX software. R2 and R3 domains are marked with black bars under the corresponding residues. Three helices of both the R2 and R3 domains are indicated with red and green boxes, respectively. The conserved MYB-bHLH interaction motif on the first and second helices of the R3 domain is underlined with a blue bar.
