HDAC19 recruits ERF4 to the MYB5a promoter and diminishes anthocyanin accumulation during grape ripening.

DNA acetylation alters the expression of responsive genes during plant development. In grapes (Vitis vinifera), however, little is known about this regulatory mechanism. In the present study, 'Kyoho' grapes treated with trichostatin A (TSA, a deacetylase inhibitor) were used for transcriptome sequencing and quantitative proteomics analysis.

Transcriptomic and Metabolomic Profiling Reveals the Effect of LED Light Quality on Fruit Ripening and Anthocyanin Accumulation in Cabernet Sauvignon Grape.

Different light qualities have various impacts on the formation of fruit quality. The present study explored the influence of different visible light spectra (red, green, blue, and white) on the formation of quality traits and their metabolic pathways in grape berries. We found that blue light and red light had different effects on the berries.
