In brief

Sequencing Grapevine

A Franco-Italian team1 has produced a high-quality draft of approximately 480 million base-pairs of the genome sequence of Vitis vinifera.2 This is the first published sequence for a fruit crop, cultivated for both fruit and beverage. Scientists have already observed striking features like the high copy number of genes related to wine flavor. This is the case for the genes coding for stilbene synthase, an enzyme that drives the synthesis of resveratrol–the compound responsible for wine's healthy benefits in moderate consumption. A similar observation is made for genes coding for enzymes involved in the synthesis of terpens and tannins (the major components of aromas), resins, and essential oils. Special attention will be given to the search for genes involved in disease resistance, to decrease fungicide and pesticide treatments and develop a more sustainable agriculture.
