The secrets of grapevine immunity have been revealed with the discovery of a new disease-causing fungus, Eutypa lata, that is responsible for a severe form of grapevine trunk disease. This fungus is a major threat to grapevine production in many countries, causing major damage to the vineyards and resulting in heavy economic losses. However, thanks to a new research study, scientists now have a better understanding of how grapevines can fight the disease.

The study, conducted by researchers at the University of California, Davis, has identified a unique network of proteins in grapevines that help the plants fight off infection by the Eutypa lata fungus. The proteins are specialized molecules that detect and respond to the presence of the fungus, triggering a complex set of defense mechanisms within the plant. These mechanisms include the production of antifungal compounds, the production of other protective proteins, and the activation of immune responses. Through this network of proteins, grapevines can effectively resist infection by the Eutypa lata fungus, helping to protect the vineyards from the devastating effects of this disease.
