Functional Descriptions:
- DkMYB14 is a bifunctional transcription factor that regulates the accumulation of proanthocyanidin in persimmon fruit.
- Demonstrate here that DkMYB14, which regulates the accumulation of PA in persimmon fruit flesh, is a bifunctional transcription factor that acts as a repressor in PA biosynthesis but becomes an activator when involved in acetaldehyde biosynthesis.
- We show that the amino acid Gly39 in the R2 domain and the ethylene response factor-associated amphiphilic repression-like motif in the C-terminal of DkMYB14 are essential for the regulation of both PA and acetaldehyde synthesis.
- Our results demonstrate that DkMYB14 functions as both a transcriptional activator and a repressor, directly repressing biosynthesis of PA and promoting its insolubilization, resulting in non-astringency in persimmon.
