Conservation of anthocyanin-related WD40 proteins in plant species. (A) Protein sequence alignment of WA1 in rice and cloned WD40 proteins in other plants. The brown underscores indicate WD40 repeats and the stars marked the amino acids of W and D. (B) Matrix analysis of percent identity and divergence among WD40 proteins in plants. (C) Phylogenetic tree of anthocyanin-related WD40 proteins in plant species. ZmPAC1 (AAM76742), AtTTG1 (Q9XGN1), SbTan1 (AFN17366), PhAN11 (AAC18914), MtWD40-1 (ABW08112), MdTTG1 (ADI58760), FaTTG1 (JQ989287), VvWDR1 (ABF66625), LWD1-XP_006829207 (Amborella trichopoda), LWD1-XP_024360619 (Physcomitrium patens). (D) Regional synteny of anthocyanin-related WD40 gene in rice, maize, sorghum, and Arabidopsis.
