Abstract:Anthocyanins are important flavonoid compounds that are abundant in Tartary buckwheat, providing a variety of bright colors and enhancing abiotic stress resistance. Our study found that FtMYB22 specifically affected anthocyanin anabolism. In this study, overexpression of the FtMYB22 transcription factor in tobacco significantly reduced the accumulation of flavonol in the petals of transgenic tobacco plants. Moreover, it significantly downregulated the expression of the genes involved in anthocyanin biosynthesi… Show more
