DcMYB7

Gene Details:

Changing Carrot Color: Insertions in DcMYB7 Alter the Regulation of Anthocyanin Biosynthesis and Modification1.
Overexpression of DcMYB7, but not DcMYB6, in the orange carrot ‘Kurodagosun’ led to anthocyanin accumulation in roots. Knockout of DcMYB7 in the solid purple (purple periderm, phloem, and xylem) carrot ‘Deep Purple’ using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 system resulted in carrots with yellow roots.
DcMYB7 could activate the expression of its DcbHLH3 partner, a homolog of the anthocyanin-related apple (Malus × domestica) bHLH3, and structural genes in the anthocyanin biosynthetic pathway.
DcMYB7 also regulated the glycosylation and acylation of anthocyanins by directly activating DcUCGXT1 and DcSAT1.
DcMYB7 Increased the Expression Levels of DcbHLH3 and Anthocyanin Biosynthesis-Related Structural Genes in Carrots.
DcMYB7 conditions glycosylation and acylation of anthocyanins via activating DcUCGXT1 and DcSAT1 in purple carrot root.
