Genes could be used to improve wine - scientists find

DNA analysis of Italian grapes has highlighted particular genes that could be used to improve berry and wine quality, scientists say.
Researchers in Italy have pinpointed certain DNA sequences that could be used to identify and breed grapevine varieties that are more suited to climate change and increase their consistency in performance.

Environmental influences can affect the qualities of grapevines, and this inconveniences the berry producers. “This can be considered a burden because the berries may mature unevenly and display large interseasonal fluctuations in quality,” the authors of the paper say this morning in the journal Genome Biology.

Grapevine berries vary in their qualities, dependent on the different regions or climates they are grown in. To investigate this, Silvia Dal Santo and her team at the Plant Genetics Lab at the University of Verona, grew a single variety of grape, the Corvina berry, across 11 different regions in Verona.
