The substrate of greatest concern in red winemaking is the pectin between grape cell
walls and within the cell wall structure; a secondary concern is the soluble pectin released upon crushing ripe fruit.
The interest in grape cell
walls has considerably increased in recent years, and it has become one of the main topics of oenological research.
Review : Condensed tannin and grape cell
wall interactions and their impact on tannin extractability into wine.
walls form a physical barrier between the juice in the vacuole of berry cells and the outside medium.
Enhancement of anthocyanin synthesis and dihydroflavonol reductase (DFR) activity in response to phosphate deprivation in grape cell
(10) Utilizing advanced molecular technology, the research team that conducted these studies evaluated possible inhibitory effects of grape cell
culture extract and subfractions on human DNA topoisomerase II catalytic activity.
Once the virus DNA is inserted into grape cell
DNA, the vine is never free of the disease.
The extractablity step in the process--getting the tannins out of the grape solid material and into must--has been investigated, with a focus on the role played by grape cell
"Tissue-specific and developmental modifications of grape cell
walls influence the adsorption of proanthocyanidins." J.
He captured the sum of all genetic instructions or transcripts present in a Cabernet Sauvignon or Chardonnay grape cell
with a microarray.
One factor he singles out is the role of polysaccharides, complex, flavorless carbohydrates found in grape cell
