Abstract Color potato is rich in anthocyanins, which is one of the natural antioxidants. In this study, one gene related to anthocyanin synthesis was cloned from the color potato “Black King Kong”, and this gene encoding protein is highly homologous to transcription factor R2R3-MYB, and named as StMyb-like . The whole length of this gene is 798 bp, which encodes a 265 amino acid, with a mole-cular weight of 30.23 kD. The expression of StMyb-like gene was analyzed by semi quantitative RT-PCR. It was found that the expression level of the gene in roots and stems was very low, but the expression level of anthocyanin in sweet potato, potato skin, buds and leaves was relatively high. In order to study the function of StMyb-like gene in color potato, the pART-MybRNAi interference vector was constructed by using DNA recombination technology, which provides a basis for fur-ther study of the possible life activities of the gene.
