Wine quotations:

“ Wine... the intellectual part of the meal” - Alexandre Dumas 1873.

To take wine into our mouths is to savor a droplet of the river of human history” - Clifton Paul Fadiman.

“ A bottle of good wine, like a good act, shines ever in the retrospect “ - Robert Louis Stevenson.

“ I have enjoyed great health at great age because everyday since I can remember I have consumed a bottle of wine except when I have not felt well...then I have consumed two bottles” - Bishop of Seville

The Deluc lab is located at the Department of Horticulture of Oregon State University in Corvallis, OR. Our lab consists of postdocs, graduate students, undergraduate students working on grape functional genomics with the common objective to understand the biology of this plant. A systems biology approach is currently developed to understand the underlying molecular mechanisms that govern the grape berry ripening.

Since 2010, we have developed a scientific project that uses as model the asynchronous cluster of Pinot Noir cultivar. As many fruits growing in a cluster, grapes suffer from developmental variability that is at the greatest at the onset of ripening also named véraison (french viticulturist name that means “change of grape berry color”). The goal of the project is to identify the genetic and the environmental factors responsible for the reduction of developmental variability towards maturity.

In grapevine, quality of grape composition at harvest relies on the subtle ratio between vegetative and reproductive growth, also named vine balance. In cool climate regions, the excess of water and nitrogen in the soils tends to maintain high vine vigor in vineyards, which favor vegetative vigor. We developed a research project aimed at understanding the relationships between vegetative and reproductive growth under reduced vine vigor conditions. Our project focuses on the quantification of several classes of hormones that are involved in the growth of expanding shoots and developing berries during the growing season
