Regulation of anthocyanin biosynthesis in fruit ripening. The oval describes the anthocyanin biosynthetic pathway which is positively regulated by MBW complex, specific growth hormones, light, and sucrose signaling. In addition, the negative regulatory factors of anthocyanin biosynthesis have been mentioned. Auxin and gibberellin negatively regulate the signaling by the other growth hormones, while COP1 and nitrogen downregulate MBW complex. Also, MYBL2 and LBD37/38/39 are negative regulators of light signaling while ethylene and gibberellin downregulate the signaling of anthocyanin biosynthesis by sucrose
