The following is an edited excerpt.
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 varieties better suited to climate change and improve berry and wine quality.
Much to the inconvenience of winemakers and drinkers, grapevine berries vary within berries on vines grown in different vineyards and in different vintages. This means they may ripen unevenly, affecting the quality of wine from place to place and from vintage to vintage. But although the differences are known to reflect environmental change and differing grape-growing practices, the molecular mechanisms underlying this variability are unclear.
