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.
Grape cell 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 suspensions.
(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 walls.
"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 walls.
