Frog eggs help researchers find new information on grapevine disease

Vitis vinifera  are common grapevines and are the world’s favorite wine-producing varietal. However, research has shown that grapevines are susceptible to powdery mildew, a plant disease, which contributes to significant crop loss for most commercial wine varietals that are cultivated each year. Now, researchers at the University of Missouri have used frog eggs to determine the cause...

Measuring grape ripeness with "electronic tongues"

Electronic tongues that provide detailed information on the degree of grape maturity could become a useful tool for grape growers, by according to research by scientists at the Universitat Politècnica de València, in collaboration with Valencia winery Torre Oria. The conclusions of this work have been published in the journal Food Research International. In their study, the...

Scientists sequence genome of high-value grape

Demystifying the chemical processes that create a wine's aroma, and the invaluable potential application of that understanding in winemaking, is the new objective of a team of scientists in Uruguay who, with European partners, also recently sequenced the genome of the high-value Tannat grape, from which "the most healthy of red wines" are fermented. Uruguayan chemistry professor...

Grapevine gene expression study aims to improve wine quality

A gene expression study of grapevine berries grown in different Italian vineyards has highlighted genes that help buffer the plants against environmental change and may explain the different quality performances of grapevine when grown in different “terroirs”. The research, reported in the open access journal Genome Biology, could be used to help identify and breed grapevine...
