Molecular characterization of a TTG1-like gene expressed in persimmon fruit
Persimmon fruit contain high concentrations of proanthocyanidins (PAs). A ternary protein complex composed of TT2 (MYB), TT8 (bHLH) and TTG1 (WD40) is necessary to activate the PAs biosynthetic genes in Arabidopsis thaliana. DkMYB4 (MYB-like) and DkMYC1 (bHLH-like) genes from persimmon have been previously identified. We have identified a WD40-like gene from persimmon coding for a protein highly similar to TTG1 from Arabidopsis thaliana. DkMYB4, DkMYC1 and DkTTG1 expression were detected in fruit flesh from the 'Hachiya' (astringent) and 'Hana Fuyu' (non-astringent) persimmon cultivars.
