The invention provides a transcription factor TaMYB3 of a MYB class, which is separated from the plateau 115 of a purple kernel wheat variety and is used for regulating the synthetization and the metabolization of anthocyanin. TaMYB3 is positioned between 0.62 and 0.95 of a long arm physical map of wheat 4B chromosome. The subcellular fraction of a protein product is positioned on a cell nucleus. Shown by a derived amino acid sequence, the TaMYB3 codes a MYB class transcription factor regulating the synthetization and the metabolization of anthocyanin. The expression quantity of the TaMYB3 in the plateau 115 of a purple kernel wheat variety increases under the induction of light.
