What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

TOWARDS IDENTIFYING PIERCES DISEASE RESISTANT GENES FROM A NATIVE AMERICAN GRAPE SPECIES (VITIS SHUTTLEWORTHII) A GENOMICS APPROACH

  • Abstract: There are over 160,000 grape ESTs in the public data bases and the vast majority of these ESTs were generated from the European grape varieties (Vitis vinifera). However, the European grapes are highly susceptible to the Pierces disease and they are not necessary possessing all the genes required for providing a full protection against the GWSS and Xf attack. On the other hand, PD resistant sources exist in some native North American grape species, particularly those species originated in the southeast United States. For example, Vitis shuttleworthii, a species originated from the southeast United States, is considered to be one of the most PD resistant grape, which has long been used for developing PD resistant grape varieties for the deep south - a most severe PD infected area. We therefore propose to search for PD resistant genes from the Vitis shuttleworthii grape.
