In a few years, a sip of Cabernet Sauvignon, Merlot or Pinot Noir may include a taste of the "Show-Me" State. The state grape of Missouri – the Norton variety grown at many vineyards around the state – is resistant to powdery mildew, a fungal pathogen that affects winemaking grapes around the world. Now, researchers at the University of Missouri are working to identify valuable genes from the Norton grape for eventual transfer into other grapes to make them less susceptible to mildew, decrease fungicide use and increase world-wide grape production.
