Multiple sequence alignment and motif compositions of GAMYB genes. (A) Sequence alignment of GAMYB proteins in Hordeum vulgare (Hv), Solanum lycopersicum (Sl), Oryza sativa (Os), Vitis vinifera (Vv), Zea mays (Zm), Arabidopsis thaliana (At), Gossypium hirsutum (Gh), Theobroma cacao (Tc), and pak choi (Brassica rapa ssp. Chinensis; Bc). The conserved R2R3 domain of GAMYB and GAMYB-like proteins is marked above the blue line, while conserved Box1, Box2, and Box3 are represented in green boxes. (B) Distribution of the conserved motifs of GAMYB genes. The sequences of the 10 motifs are exhibited at the bottom.
