Isolation and characterization of a basic Helix-Loop-Helix transcription factor gene potentially involved in proanthocyanidin biosynthesis regulation in persimmon (Diospyros kaki Thunb.)

► DkMYC1 is a novel gene encoding a basic Helix-Loop-Helix transcription factors in persimmon. ► The expression of DkMYC1 is analyzed in two pollination-constant non-astringent and one astringent persimmon cultivars during fruits development. ► The expression pattern of DkMYC1 correlates with PAs accumulation in the three cultivars. ► The expression pattern of DkMYC1 is in accordance with PAs pathway genes DkDHD, DkF3′5′H, DkANR.
