New wheat gene TaMYB3 for regulating synthetization and metabolization of anthocyanin

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. The TaMYB3 can promote skin cells of the plateau 115 kernels after dark treatment to synthetize anthocyanin under the existence of transcription factors ZmR of corns bHLH during transient expression. Single TaMYB3 genes and single ZmR genes can not induct the synthetization of anthocyani, which shows that the TaMYB3 genes have the transcriptional activity of regulating the synthetization and the metabolization of anthocyanin. barly strip mosaic virus (BSMV) mediates the expression quantity decrease of the TaMYB3 in the plateau 115 kernels, and reduces the quantity of anthocyanin in kernels. This shows that the TaMYB3 participates in the biosynthesis of anthocyanin in the plateau 115 kernels.
