    Abstract
    Methylation at the MdMYB1 promoter in apple sports has been reported as a regulator of the anthocyanin pathway, but little is known about how the locus is recognized by the methylation machinery to regulate anthocyanin accumulation. In this study, we analyzed three differently colored ‘Fuji' apples and found that differences in the transcript levels of MdMYB1, which encodes a key regulator of anthocyanin biosynthesis, control the anthocyanin content in fruit skin. The CHH methylation levels in the MR3 region of the MdMYB1 promoter were found to be negatively correlated with MdMYB1...
