GENETIC-BASED EARLY DETECTION Another project goal is to develop a plant-based detec- tion tool to analyze healthy vine leaves with no symptoms for grape genes or a molecular signature associated with fungal infection. Baumgartner said, "We're looking for the presence of genes that may produce antibodies or proteins to fight fun- gal disease that occur before the disease starts spreading." Dr. Grant Cramer of the University of Nevada in Reno is working to identify genomic traits as indicators of vine infec- tion and susceptibility that can be used for analytical test- ing. The reason for looking at genetic disease signatures in leaves is that they can be more easily collected by growers and ground up for lab testing than woody vine parts. "As with developing an early detection tool with spore trapping, this genetic detection tool must be technically and economically feasible for growers and for diagnostic labs," Baumgartner explained. This tool would also benefit grapevine nurseries and clean- %URO-ACHINES )NC 7EST &AIRFIELD #! 0HONE %AST #ULPEPER 6! 0HONE INFO EUROMACHINESUSACOM WWWEUROMACHINESUSACOM !
